This is the study of nutrient Foramina in the shaft of upper limb long bones taken from the department of Anatomy at Narayana medical college nellore. Nutrient foramina play an important role in nutrition and growth of the bones. Most of the nutrient arteries follow the rule, 'to the elbow I go, from the knee I flee' but they are very variable in position. Their number, location, direction & its importance in the growing end of long bones were studied in the long bones of upper limb. The present study has variations in the position & direction of long bones especially in the radius & ulna, as most of the nutrient foramina are found in anterior surface of upper 1/3rd and middle 1/3rd of these bones. The study of nutrient foramina is not only of academic interest but also in medico-legal practice in relation to their position. Careful observation has also been made on the position of nutrient foramina in relation to upper end of long bones. This study also gives importance of length long bones to know the height of an individual. With the knowledge of variations in the nutrient foramen, placement of internal fixation devices can be appropriately done. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutrient%20artery" title="nutrient artery">nutrient artery</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20foramina" title=" nutrient foramina"> nutrient foramina</a>, <a href="https://publications.waset.org/abstracts/search?q=shaft%20of%20long%20bones" title=" shaft of long bones"> shaft of long bones</a>, <a href="https://publications.waset.org/abstracts/search?q=upper%20limb%20bones" title=" upper limb bones"> upper limb bones</a> </p> <a href="https://publications.waset.org/abstracts/42312/nutrient-foramina-in-the-shaft-of-long-bones-of-upper-limb" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42312.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">502</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">657</span> Simulation of 'Net' Nutrients Removal by Green Mussel (Perna viridis) in Estuarine and Coastal Areas </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chayarat%20Tantanasarit">Chayarat Tantanasarit</a>, <a href="https://publications.waset.org/abstracts/search?q=Sandhya%20Babel"> Sandhya Babel</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Green mussels (Perna viridis) can effectively remove nutrients from seawater through their filtration process. This study aims to estimate 'net' nutrient removal rate by green mussel through calculation of nutrient uptake and release. Nutrients (carbon, nitrogen, and phosphorus) uptake was calculated based on the mussel filtration rate. Nutrient release was evaluated from carbon, nitrogen, and phosphorus released as mussel feces. By subtracting nutrient release from nutrient uptake, net nutrient removal by green mussel can be found as 3302, 380 and 124 mg/year/indv. Mass balance model was employed to simulate nutrient removal in actual green mussel farming conditions. Mussels farm area, seawater flow rate and amount of mussels were considered in the model. Results show that although larger quantity of green mussel farms lead to higher nutrient removal rate, the maximum green mussel cultivation should be taken into consideration as nutrients released through mussel excretion can strongly affect marine ecosystem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon" title="carbon">carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=ecretion" title=" ecretion"> ecretion</a>, <a href="https://publications.waset.org/abstracts/search?q=filtration" title=" filtration"> filtration</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen" title=" nitrogen"> nitrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=phosphorus" title=" phosphorus"> phosphorus</a> </p> <a href="https://publications.waset.org/abstracts/2464/simulation-of-net-nutrients-removal-by-green-mussel-perna-viridis-in-estuarine-and-coastal-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/2464.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">400</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">656</span> Nutrient Removal and Microalgal Biomass Growth of Chlorella Vulgaris in Response to Centrate Wastewater Loadings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lingfeng%20Wang">Lingfeng Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhipeng%20Chen"> Zhipeng Chen</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuang%20Qiu"> Shuang Qiu</a>, <a href="https://publications.waset.org/abstracts/search?q=Shijian%20Ge"> Shijian Ge</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effects of wastewater, with four different nutrient loadings, from synthetic centrate on biomass production of Chlorella vulgaris, nutrient removal, microalgal settling, and lipid production were investigated in photobioreactors under both batches and, subsequently, semi-continuous operations. At higher centrate concentration factors (17.2% and 36.2%), hydraulic retention time and pH adjustments could be employed to sustain acceptable microalgal growth rates and wastewater treatment. Similar nutrient removals efficiencies (>95%) and biomass production (0.42-0.51 g/L) were observed for the four centrate concentrations. Both the lipid productivity and lipid content decreased with increasing nutrient loading in the wastewater. The results also demonstrated that the mass ratio of carbohydrate to protein could provide a good indication of microalgal settling performance, rather than sole component composition or total extracellular polymeric substances. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lipid%20production" title="lipid production">lipid production</a>, <a href="https://publications.waset.org/abstracts/search?q=microalgae" title=" microalgae"> microalgae</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20removal" title=" nutrient removal"> nutrient removal</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater" title=" wastewater"> wastewater</a> </p> <a href="https://publications.waset.org/abstracts/94539/nutrient-removal-and-microalgal-biomass-growth-of-chlorella-vulgaris-in-response-to-centrate-wastewater-loadings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94539.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">240</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">655</span> Quantitative Analysis of Nutrient Inflow from River and Groundwater to Imazu Bay in Fukuoka, Japan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Keisuke%20Konishi">Keisuke Konishi</a>, <a href="https://publications.waset.org/abstracts/search?q=Yoshinari%20Hiroshiro"> Yoshinari Hiroshiro</a>, <a href="https://publications.waset.org/abstracts/search?q=Kento%20Terashima"> Kento Terashima</a>, <a href="https://publications.waset.org/abstracts/search?q=Atsushi%20Tsutsumi"> Atsushi Tsutsumi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Imazu Bay plays an important role for endangered species such as horseshoe crabs and black-faced spoonbills that stay in the bay for spawning or the passing of winter. However, this bay is semi-enclosed with slow water exchange, which could lead to eutrophication under the condition of excess nutrient inflow to the bay. Therefore, quantification of nutrient inflow is of great importance. Generally, analysis of nutrient inflow to the bays takes into consideration nutrient inflow from only the river, but that from groundwater should not be ignored for more accurate results. The main objective of this study is to estimate the amounts of nutrient inflow from river and groundwater to Imazu Bay by analyzing water budget in Zuibaiji River Basin and loads of T-N, T-P, NO3-N and NH4-N. The water budget computation in the basin is performed using groundwater recharge model and quasi three-dimensional two-phase groundwater flow model, and the multiplication of the measured amount of nutrient inflow with the computed discharge gives the total amount of nutrient inflow to the bay. In addition, in order to evaluate nutrient inflow to the bay, the result is compared with nutrient inflow from geologically similar river basins. The result shows that the discharge is 3.50×107 m3/year from the river and 1.04×107 m3/year from groundwater. The submarine groundwater discharge accounts for approximately 23 % of the total discharge, which is large compared to the other river basins. It is also revealed that the total nutrient inflow is not particularly large. The sum of NO3-N and NH4-N loadings from groundwater is less than 10 % of that from the river because of denitrification in groundwater. The Shin Seibu Sewage Treatment Plant located below the observation points discharges treated water of 15,400 m3/day and plans to increase it. However, the loads of T-N and T-P from the treatment plant are 3.9 mg/L and 0.19 mg/L, so that it does not contribute a lot to eutrophication. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eutrophication" title="Eutrophication">Eutrophication</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20recharge%20model" title=" groundwater recharge model"> groundwater recharge model</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20inflow" title=" nutrient inflow"> nutrient inflow</a>, <a href="https://publications.waset.org/abstracts/search?q=quasi%20three-dimensional%20two-phase%20groundwater%20flow%20model" title=" quasi three-dimensional two-phase groundwater flow model"> quasi three-dimensional two-phase groundwater flow model</a>, <a href="https://publications.waset.org/abstracts/search?q=submarine%20groundwater%20discharge" title=" submarine groundwater discharge "> submarine groundwater discharge </a> </p> <a href="https://publications.waset.org/abstracts/48578/quantitative-analysis-of-nutrient-inflow-from-river-and-groundwater-to-imazu-bay-in-fukuoka-japan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/48578.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">654</span> Dietary Nutrient Consumption Patterns by the Pregnant Mother in Dhaka City, Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kazi%20Muhammad%20Rezaul%20Karim">Kazi Muhammad Rezaul Karim</a>, <a href="https://publications.waset.org/abstracts/search?q=Tasmia%20Tasnim"> Tasmia Tasnim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Pregnancy is a condition of higher nutrient requirement but in developing countries like Bangladesh most of the pregnant women can not meet their nutrient requirement and sometimes they are neglected in the family. The purpose of the study was to assess the nutritional status and dietary nutrient intake by the pregnant women, in Dhaka city, Bangladesh. Methods: The study population comprised of pregnant women from urban or semi-urban, aged between 18 to 35 and free of pregnancy related complication and other diseases. Under a cross-sectional design, 30 healthy non-pregnant as well as 130 pregnant women, at 3 different trimesters of pregnancy were assessed. A questionnaire was developed to obtain demographic, socio-economic, anthropometric, drug and medical history. Three day consecutive 24-hour food recalls were used to assess food intake and then converted to nutrient intake. Results: The average BMI of the nonpregnant women was 22.89 ± 3.4 kg/m2 and that of pregnant women was 23.52 ± 3.71 kg/m2. The mean dietary nutrient intake of dietary fiber, calorie, protein, fat, carbohydrate, calcium, iron, thiamine, riboflavin, vitamin C, Vitamin A, folate, vitamin B6 and Vitamin B12 of the pregnant mothers were 4.38 g, 1619 kcal, 60.05 g, 30.38 g, 268.79 g, 537.21 mg, 21.53 mg, 1.15 mg, 0.94 mg, 97.36 mg, 647.6 µg, 153.93 µg, 1.41 mg and 4.09 µg respectively. Most of pregnant women (more than 90%) can not meet their energy, calcium and folate requirements. Conclusion: Most of the pregnant mother in Bangladesh can not meet their dietary requirements during pregnancy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title="pregnancy">pregnancy</a>, <a href="https://publications.waset.org/abstracts/search?q=dietary%20nutrient" title=" dietary nutrient"> dietary nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20status" title=" nutritional status"> nutritional status</a>, <a href="https://publications.waset.org/abstracts/search?q=BMI" title=" BMI"> BMI</a> </p> <a href="https://publications.waset.org/abstracts/6089/dietary-nutrient-consumption-patterns-by-the-pregnant-mother-in-dhaka-city-bangladesh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6089.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">439</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">653</span> Molecular Profiling of an Oleaginous Trebouxiophycean Alga Parachlorella kessleri Subjected to Nutrient Deprivation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pannaga%20Pavan%20Jutur">Pannaga Pavan Jutur</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Parachlorella kessleri, a marine unicellular green alga belonging to class Trebouxiophyceae, accumulates large amounts of oil, i.e., lipids under nutrient-deprived (-N, -P, and -S) conditions. Understanding their metabolic imprints is important for elucidating the physiological mechanisms of lipid accumulations in this microalga subjected to nutrient deprivation. Metabolic and lipidomic profiles were obtained respectively using gas chromatography-mass spectrometry (GC-MS) of P. kessleri under nutrient starvation (-N, -P and -S) conditions. Relative quantities of more than 100 metabolites were systematically compared in all these three starvation conditions. Our results demonstrate that in lipid metabolism, the quantities of neutral lipids increased significantly followed by the decrease in other metabolites involved in photosynthesis, nitrogen assimilation, etc. In conclusion, the metabolomics and lipidomic profiles have identified a few common metabolites such as citric acid, valine, and trehalose to play a significant role in the overproduction of oil by this microalga subjected to nutrient deprivation. Understanding the entire system through untargeted metabolome profiling will lead to identifying relevant metabolites involved in the biosynthesis and degradation of precursor molecules that may have the potential for biofuel production, aiming towards the vision of tomorrow’s bioenergy needs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=algae" title="algae">algae</a>, <a href="https://publications.waset.org/abstracts/search?q=biofuels" title=" biofuels"> biofuels</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20stress" title=" nutrient stress"> nutrient stress</a>, <a href="https://publications.waset.org/abstracts/search?q=omics" title=" omics"> omics</a> </p> <a href="https://publications.waset.org/abstracts/82900/molecular-profiling-of-an-oleaginous-trebouxiophycean-alga-parachlorella-kessleri-subjected-to-nutrient-deprivation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/82900.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">275</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">652</span> Macroscopic Anatomy of the Nutrient Foramina of Human Scaphoid Bone</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20V.%20Murlimanju">B.

The fracture can damage the arteries and would cause avascular necrosis of the scaphoid. In this present study, the goal was to study the topography and number of nutrient foramina in the scaphoid bones of South Indian population. Methods: We studied 46 human scaphoid bones, among them 20 were left sided and 26 belonged to the right side. The scaphoid bones were available at the department of anatomy of our institution. The scaphoid bones were macroscopically observed for the topography and number of nutrient foramina. The data was collected, tabulated and analyzed. Results: The nutrient foramina were observed in all the scaphoid bones (100%). The locations of the foramina were over the non-articular surfaces in all these scaphoids. They were distributed over the palmar and dorsal surfaces. The foramina were found proximal as well as distal to the mid waist of the scaphoid bone. Their number ranged between 9 and 54 in each scaphoid bone. The number ranged between 2-24 over the palmar surface and 7-36 over the dorsal surface. They ranged between 2-24 proximal to the waist and 3-39 distal to the waist. Conclusion: The knowledge of arterial supply, topography of nutrient foramen and their number is essential to understand the concepts of avascular necrosis of scaphoid bone. It will be enlightening to understand the non-union of the fracture of waist of the scaphoid. The morphological data is required to the operating hand surgeon. We do believe that the present study has provided additional information about the topography and number of nutrient foramina of the human scaphoid bones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=avascular%20necrosis" title="avascular necrosis">avascular necrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20foramen" title=" nutrient foramen"> nutrient foramen</a>, <a href="https://publications.waset.org/abstracts/search?q=scaphoid" title=" scaphoid"> scaphoid</a>, <a href="https://publications.waset.org/abstracts/search?q=vascular" title=" vascular"> vascular</a> </p> <a href="https://publications.waset.org/abstracts/42463/macroscopic-anatomy-of-the-nutrient-foramina-of-human-scaphoid-bone" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42463.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">269</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">651</span> Nutrient Foramina of the Lunate Bone of the Hand – an Anatomical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.J.%20Jiji">P.J.

The dislocation can interrupt the vasculature and would cause avascular necrosis. The objective of the present study was to study the morphology and number of the nutrient foramina in the cadaveric dried lunate bones of the Indian population. Methods: The present study included 28 lunate bones (13 right sided and 15 left sided) which were obtained from the gross anatomy laboratory of our institution. The bones were macroscopically observed for the nutrient foramina and the data was collected with respect to their number. The tabulation of the data and analysis were done. Results: All of our specimens (100%) exhibited the nutrient foramina over the non-articular surfaces. The foramina were observed only over the palmar and dorsal surfaces of the lunate bones. The foramen ranged between 2 and 10. The foramina were more in number over the dorsal surface (average number 3.3) in comparison to the palmar surface (average number 2.4). Conclusion: We believe that the present study has provided important data about the nutrient foramina of the lunate bones. The data is enlightening to the orthopedic surgeon and would help in the hand surgeries. The morphological knowledge of the vasculature, their foramina of entry and their number is required to understand the concepts in the lunatomalacia and Kienbock’s disease. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=avascular%20necrosis" title="avascular necrosis">avascular necrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=foramen" title=" foramen"> foramen</a>, <a href="https://publications.waset.org/abstracts/search?q=lunate" title=" lunate"> lunate</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient" title=" nutrient "> nutrient </a> </p> <a href="https://publications.waset.org/abstracts/27487/nutrient-foramina-of-the-lunate-bone-of-the-hand-an-anatomical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27487.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">244</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">650</span> Response of Onion to FTM and Inorganic Fertilizers Application on Growth, Yield and Nutrient Uptake in Lateritic Soil of Konkan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rupali%20Thorat">Rupali Thorat</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20B.%20Dodake"> S.

There were 12 treatment combinations, comprising of 3 levels of NPK fertilizers (C1 ,C2-125 kg N, 62.5 kg P205 and 62.5 kg K20 ha-1 and C3-150 kg N, 75 kg P205 and 75 kg K20 ha-1) and 4 levels of FYM (F1-10 t FYM ha-1, F2 - 15 t FYM ha-1, F3-20 t FYM ha-1, F4-25 t FYM ha-1) replicated thrice using Factorial Randomized Block Design. The observations on plant height, number of leaves, girth of plant, polar and equatorial diameter of bulb as well as dry matter yield, onion bulb yield recorded during the course of field study were subjected to statistical analysis. Similarly nutrient content and uptake, quality parameters of bulb and soil properties were also determined and their data were also analyzed statistically. It is revealed from the study that the growth attributes, dry matter yield, onion bulb yield, nutrient content, nutrient uptake, quality parameters were improved significantly due to application of NPK @ 150:75:75 kg ha-1 along with FYM @ 20 t ha-1(C3F3). Application of NPK @ 150:75:75 kg ha-1 along with FYM @ 20 t ha-1 (C3F3) registered highest onion bulb yield (t ha-1). The quality of onion as well as availability of N, P, K, Fe, Mn, Zn and Cu in the soil was improved due to application of NPK @ 150:75:75 kg ha-1 and FYM @ 20 t ha-1. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=onion" title="onion">onion</a>, <a href="https://publications.waset.org/abstracts/search?q=FYM" title=" FYM"> FYM</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20uptake%20and%20fertilizer" title=" nutrient uptake and fertilizer"> nutrient uptake and fertilizer</a> </p> <a href="https://publications.waset.org/abstracts/23182/response-of-onion-to-ftm-and-inorganic-fertilizers-application-on-growth-yield-and-nutrient-uptake-in-lateritic-soil-of-konkan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23182.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">486</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">649</span> Assessing Impacts of Climate Variability and Change on Water Productivity and Nutrient Use Efficiency of Maize in the Semi-arid Central Rift Valley of Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fitih%20Ademe">Fitih Ademe</a>, <a href="https://publications.waset.org/abstracts/search?q=Kibebew%20Kibret"> Kibebew Kibret</a>, <a href="https://publications.waset.org/abstracts/search?q=Sheleme%20Beyene"> Sheleme Beyene</a>, <a href="https://publications.waset.org/abstracts/search?q=Mezgebu%20Getnet"> Mezgebu Getnet</a>, <a href="https://publications.waset.org/abstracts/search?q=Gashaw%20Meteke"> Gashaw Meteke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Changes in precipitation, temperature and atmospheric CO2 concentration are expected to alter agricultural productivity patterns worldwide. The interactive effects of soil moisture and nutrient availability are the two key edaphic factors that determine crop yield and are sensitive to climatic changes. The study assessed the potential impacts of climate change on maize yield and corresponding water productivity and nutrient use efficiency under climate change scenarios for the Central Rift Valley of Ethiopia by mid (2041-2070) and end century (2071-2100). Projected impacts were evaluated using climate scenarios generated from four General Circulation Models (GCMs) dynamically downscaled by the Swedish RCA4 Regional Climate Model (RCM) in combination with two Representative Concentration Pathways (RCP 4.5 and RCP8.5). Decision Support System for Agro-technology Transfer cropping system model (DSSAT-CSM) was used to simulate yield, water and nutrient use for the study periods. Results indicate that rainfed maize yield might decrease on average by 16.5 and 23% by the 2050s and 2080s, respectively, due to climate change. Water productivity is expected to decline on average by 2.2 and 12% in the CRV by mid and end centuries with respect to the baseline. Nutrient uptake and corresponding nutrient use efficiency (NUE) might also be negatively affected by climate change. Phosphorus uptake probably will decrease in the CRV on average by 14.5 to 18% by 2050s, while N uptake may not change significantly at Melkassa. Nitrogen and P use efficiency indicators showed decreases in the range between 8.5 to 10.5% and between 9.3 to 10.5%, respectively, by 2050s relative to the baseline average. The simulation results further indicated that a combination of increased water availability and optimum nutrient application might increase both water productivity and nutrient use efficiency in the changed climate, which can ensure modest production in the future. Potential options that can improve water availability and nutrient uptake should be identified for the study locations using a crop modeling approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=crop%20model" title="crop model">crop model</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change%20scenario" title=" climate change scenario"> climate change scenario</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20uptake" title=" nutrient uptake"> nutrient uptake</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20use%20efficiency" title=" nutrient use efficiency"> nutrient use efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20productivity" title=" water productivity"> water productivity</a> </p> <a href="https://publications.waset.org/abstracts/175106/assessing-impacts-of-climate-variability-and-change-on-water-productivity-and-nutrient-use-efficiency-of-maize-in-the-semi-arid-central-rift-valley-of-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/175106.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">86</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">648</span> The Nutrient Foramen of the Scaphoid Bone – A Morphological Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=B.%20V.%20Murlimanju">B.

The fracture may disrupt the vessels and end up as the avascular necrosis of the bone. The objective of the present study was to investigate the morphology and number of the nutrient foramina in the cadaveric dried scaphoid bones of the Indian population. Methods: The present study included 46 scaphoid bones (26 right sided and 20 left sided) which were obtained from the gross anatomy laboratory of our institution. The bones were macroscopically observed for the nutrient foramina and the data was collected with respect to their number. The tabulation of the data and analysis were done. Results: All of our specimens (100%) exhibited the nutrient foramina over the non-articular surfaces. The foramina were observed only over the palmar and dorsal surfaces of the scaphoid bones. The foramina were observed both proximal and distal to the mid waist of the scaphoid bone. The foramen ranged between 9 and 54 in each scaphoid bone. The foramina over the palmar surface ranged between, 2-24 in number. The foramina over the dorsal surface ranged between, 7-36 in number. The foramina proximal to the waist ranged between 2 and 24 in number and distal to the waist ranged between 3 and 39. Conclusion: We believe that the present study has provided additional data about the nutrient foramina of the scaphoid bones. The data is enlightening to the orthopedic surgeon and would help in the hand surgeries. The morphological knowledge of the vasculature, their foramina of entry and their number is required to understand the concepts in the avascular necrosis of the proximal scaphoid and non-union of the fracture at the waist of the scaphoid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=avascular%20necrosis" title="avascular necrosis">avascular necrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient" title=" nutrient"> nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=scaphoid" title=" scaphoid"> scaphoid</a>, <a href="https://publications.waset.org/abstracts/search?q=vascular" title=" vascular"> vascular</a> </p> <a href="https://publications.waset.org/abstracts/27733/the-nutrient-foramen-of-the-scaphoid-bone-a-morphological-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27733.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">343</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">647</span> Ultrasonic Assisted Growth of ZnO Nanorods at Low Temperature </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khairul%20Anuar">Khairul Anuar</a>, <a href="https://publications.waset.org/abstracts/search?q=Wai%20Yee%20Lee"> Wai Yee Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20C.%20S.%20Bien"> Daniel C.

The results show that the ZnO nanorods are successfully grown on the sample annealed at 50°C in the sonicated ZnO nutrient solution with a length and a diameter of approximately 8.025 µm and 92 nm, respectively. However, no ZnO nanorods structures are observed for the sample annealed at 50°C and grown in unsonicated ZnO nutrient solution. Meanwhile, the ZnO nanorods for the sample annealed at 100°C are successfully grown in both sonicated and unsonicated ZnO nutrient solutions. The length and diameter of the nanorods for the sample grown in the sonicated solution are 8.681 µm and 1.033 nm, whereas those for the sample grown in the unsonicated solution are 7.613 µm and 1.040 nm. This result shows that with ultrasonic treatment, the length of the ZnO nanorods increases by 14%, whereas their diameter is reduced by 0.7%, resulting in an increase of aspect ratio from 7:1 to 8:1. Electroconductivity and pH sensors are used to measure the conductivity and acidity level of the sonicated and unsonicated solutions, respectively. The result shows that the conductivity increases from 87 mS/cm to 10.4 mS/cm, whereas the solution pH decreases from 6.52 to 6.13 for the sonicated and unsonicated solutions, respectively. The increase in solution conductivity and acidity level elucidates the higher amount of zinc nutrient in the sonicated solution than in the unsonicated solution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ultrasonic%20treatment" title="ultrasonic treatment">ultrasonic treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20annealing%20temperature" title=" low annealing temperature"> low annealing temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=ZnO%20nanostructure" title=" ZnO nanostructure"> ZnO nanostructure</a>, <a href="https://publications.waset.org/abstracts/search?q=nanorods" title=" nanorods"> nanorods</a> </p> <a href="https://publications.waset.org/abstracts/10106/ultrasonic-assisted-growth-of-zno-nanorods-at-low-temperature" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10106.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">646</span> The Effect of Fermentation and Germination on the Nutrient and Antinutrient Composition of Lima Bean (Phaseolus lunatus) Flour</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20N.%20Okeke">P.

In this study, the influence of fermentation and germination on the chemical properties of Lima bean (Phaseolus lunatus) flour were evaluated. The flours were analyzed for their proximate and mineral composition, using the standard assay methods. The result showed that fermentation and germination increased the moisture, protein and ash content of the flours while fiber, fat and carbohydrate were decreased. The protein level of fermented and germinated lima bean increased from 21.06–26.60%. The minerals: iron, copper, zinc, and phosphorous increased due to germination and fermentation. The phytate and tannin levels were drastically reduced in both the fermented and germinated flours. The result of this study revealed that fermentation and germination makes the nutrient in lima beans more accessible as it reduces the anti-nutrients. It is therefore recommended that lima bean be process accordingly for richer and more bio-availability of the nutrients. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutrient" title="nutrient">nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-nutrient" title=" anti-nutrient"> anti-nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=fermented" title=" fermented"> fermented</a>, <a href="https://publications.waset.org/abstracts/search?q=germinated" title=" germinated"> germinated</a>, <a href="https://publications.waset.org/abstracts/search?q=lima%20bean%20flour" title=" lima bean flour "> lima bean flour </a> </p> <a href="https://publications.waset.org/abstracts/22168/the-effect-of-fermentation-and-germination-on-the-nutrient-and-antinutrient-composition-of-lima-bean-phaseolus-lunatus-flour" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/22168.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">390</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">645</span> Developing a Town Based Soil Database to Assess the Sensitive Zones in Nutrient Management</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sefa%20Aksu">Sefa Aksu</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%9Cnal%20K%C4%B1z%C4%B1l"> Ünal Kızıl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For this study, a town based soil database created in Gümüşçay District of Biga Town, Çanakkale, Turkey.

We examined the yield, the yield production per 1kg NPK fertilizer and the water and nutrient utilization of hybrid PR37N01 and PR37M81 in 2013. We found that PR37N01 produced the most yield at the level of N120+P (17,476kg ha-1) while PR37M81 reached the highest yield at level N150+PK (16,754kg ha-1). Studies related to yield production per 1kg NPK indicated that the best results were achieved at level N30+PK compared to the control treatment. Yield production per 1kg NPK was17.6kg kg-1 by P37N01 and 44.2kg kg-1 by PR37M81. By comparing the water utilization of hybrids we found that the worst water utilization results were reached in the control treatment (PR37N01: 26.2kg mm-1, PR37M81: 19.5kg mm-1). The best water utilization values were produced at level N120+PK in the case of hybrid PR37N01 (32.1kg mm-1) and at N150+PK in the case of hybrid PR37M81 (30.8kg mm-1). We established the values of the nutrient reaction and the fertilizer optimum of hybrids. We discovered a strong relationship between the amount of fertilizer applied and the yield produced (r2= 0.8228–0.9515). The best nutrient response was induced by hybrid PR37N01, while the weakest results were reached by hybrid PR37M81. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid" title="hybrid">hybrid</a>, <a href="https://publications.waset.org/abstracts/search?q=maize" title=" maize"> maize</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient" title=" nutrient"> nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield"> yield</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20utilization" title=" water utilization"> water utilization</a> </p> <a href="https://publications.waset.org/abstracts/3689/examination-of-the-water-and-nutrient-utilization-of-maize-hybrids-on-chernozem-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3689.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">413</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">643</span> Adaptive Strategies to Nutrient Deficiency of Doubled Diploid Citrumelo 4475: A Prospective Study Based on Structural, Ultrastructural, Physiological and Biochemical Parameters </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20Oustric">J.

Santini</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Nowadays, the objective of durable agriculture, and in particular organic agriculture, is to reduce the level of fertilizer inputs used in crops. Limiting the quantity of fertilizer inputs would optimize the economical result and minimizing the environmental impact. Nutrient deficiency, particularly of a major nutrient (N, P, and K), can seriously affect fruit production and quality. In citrus crops, rootstock/scion combinations. In citrus crop, scion/rootstock combinations are used frequently to improve tolerance to various abiotic stresses. New rootstocks are needed to respond to these constraints, and the use of new tetraploid rootstocks better adapted to lower nutrient intake could offer a promising way forward. The aim of this work was to determine whether a better tolerance to nutrient deficiency could be observed in a doubled diploid seedling and whether this tolerance could be observed in common clementine scion if used as rootstocks. We selected diploid (CM2x) and doubled diploid (CM4x) Citrumelo 4475 seedlings and common clementine (C) grafted onto Citrumelo 4475 diploid (C/CM2x) and doubled diploid (C/CM4x) rootstocks. Nutrient deficiency effects on the seedlings and scion/rootstock combinations were analyzed by studying anatomical, structural and ultrastructural determinants (chlorosis, stomata, ostiole and cells and their organelles), photosynthetic properties (leaf net photosynthetic rate (Pₙₑₜ), stomatal conductance (gₛ), chlorophyll a fluorescence (Fᵥ/Fₘ)) and oxidative marker (malondialdehyde). Nutrient deficiency affected differently foliar tissues, physiological parameters, and oxidative metabolism in leaves of seedlings depending on their ploidy level and of common clementine scion depending on their rootstocks ploidy level. Both CM4x and C/CM4x presented lower foliar damages (chlorosis, chloroplasts, mitochondria, and plastoglobuli), photosynthesis processes alteration (Pₙₑₜ, gₛ, and Fᵥ/Fₘ), and malondialdehyde accumulation than CM2x and C/CM2x after nutrient deficiency. Doubled diploid Citrumelo 4475 can improve nutrient deficiency tolerance, and its use as a rootstock allows to confer this tolerance to the common clementine scion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutrient%20deficiency" title="nutrient deficiency">nutrient deficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=photosynthesis" title=" photosynthesis"> photosynthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=polyploid%20rootstocks" title=" polyploid rootstocks"> polyploid rootstocks</a> </p> <a href="https://publications.waset.org/abstracts/132134/adaptive-strategies-to-nutrient-deficiency-of-doubled-diploid-citrumelo-4475-a-prospective-study-based-on-structural-ultrastructural-physiological-and-biochemical-parameters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132134.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">128</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">642</span> A Review of the Factors That Influence on Nutrient Removal in Upflow Filters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Alzeyadi">Ali Alzeyadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Edward%20Loffill"> Edward Loffill</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafid%20Alkhaddar%0D%0AAli%20Alattabi"> Rafid Alkhaddar Ali Alattabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phosphate, ammonium, and nitrates are forms of nutrients; they are released from different sources. High nutrient levels contribute to the eutrophication of water bodies by accelerating the extraordinary growth of algae. Recently, many filtration and treatment systems were developed and used for different removal processes. Due to enhanced operational aspects for the up-flow, continuous, granular Media filter researchers became more interested in further developing this technology and its performance for nutrient removal from wastewater. Environmental factors significantly affect the filtration process performance, and understanding their impact will help to maintain the nutrient removal process. Phosphate removal by phosphate sorption materials PSMs and nitrogen removal biologically are the methods of nutrient removal that have been discussed in this paper. Hence, the focus on the factors that influence these processes is the scope of this work. The finding showed the presence of factors affecting both removal processes; the size, shape, and roughness of the filter media particles play a crucial role in supporting biofilm formation. On the other hand, all of which are effected on the reactivity of surface between the media and phosphate. Many studies alluded to factors that have significant influence on the biological removal for nitrogen such as dissolved oxygen, temperature, and pH; this is due to the sensitivity of biological processes while the phosphate removal by PSMs showed less affected by these factors. This review work provides help to the researchers in create a comprehensive approach in regards study the nutrient removal in up flow filtration systems. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nitrogen%20biological%20treatment" title="nitrogen biological treatment">nitrogen biological treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrients" title=" nutrients"> nutrients</a>, <a href="https://publications.waset.org/abstracts/search?q=psms" title=" psms"> psms</a>, <a href="https://publications.waset.org/abstracts/search?q=upflow%20filter" title=" upflow filter"> upflow filter</a>, <a href="https://publications.waset.org/abstracts/search?q=wastewater%20treatment" title=" wastewater treatment"> wastewater treatment</a> </p> <a href="https://publications.waset.org/abstracts/40270/a-review-of-the-factors-that-influence-on-nutrient-removal-in-upflow-filters" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40270.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">322</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">641</span> Growth Performance and Nutrient Digestibility of Cirrhinus mrigala Fingerlings Fed on Sunflower Meal Based Diet Supplemented with Phytase</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Syed%20Makhdoom%20Hussain">Syed Makhdoom Hussain</a>, <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Afzal"> Muhammad Afzal</a>, <a href="https://publications.waset.org/abstracts/search?q=Farhat%20Jabeen"> Farhat Jabeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Arshad%20Javid"> Arshad Javid</a>, <a href="https://publications.waset.org/abstracts/search?q=Tasneem%20Hameed"> Tasneem Hameed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A feeding trial was conducted with Cirrhinus mrigala fingerlings to study the effects of microbial phytase with graded levels (0, 500, 1000, 1500, and 2000 FTUkg-1) by sunflower meal based diet on growth performance and nutrient digestibility. The chromic oxide was added as an indigestible marker in the diets. Three replicate groups of 15 fish (Average wt 5.98 g fish-1) were fed once a day and feces were collected twice daily. The results of present study showed improved growth and feed performance of Cirrhinus mrigala fingerlings in response to phytase supplementation. Maximum growth performance was obtained by the fish fed on test diet-III having 1000 FTU kg-1 phytase level. Similarly, nutrient digestibility was also significantly increased (p<0.05) by phytase supplementation. Digestibility coefficients for sunflower meal based diet increased 15.76%, 17.70%, and 12.70% for crude protein, crude fat and apparent gross energy as compared to the reference diet, respectively at 1000 FTU kg-1 level. Again, maximum response of nutrient digestibility was recorded at the phytase level of 1000 FTU kg-1 diet. It was concluded that the phytase supplementation to sunflower meal based diet at 1000 FTU kg-1 level is optimum to release adequate chelated nutrients for maximum growth performance of C. mrigala fingerlings. Our results also suggested that phytase supplementation to sunflower meal based diet can help in the development of sustainable aquaculture by reducing the feed cost and nutrient discharge through feces in the aquatic ecosystem. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sunflower%20meal" title="sunflower meal">sunflower meal</a>, <a href="https://publications.waset.org/abstracts/search?q=Cirrhinus%20mrigala" title=" Cirrhinus mrigala"> Cirrhinus mrigala</a>, <a href="https://publications.waset.org/abstracts/search?q=growth" title=" growth"> growth</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20digestibility" title=" nutrient digestibility"> nutrient digestibility</a>, <a href="https://publications.waset.org/abstracts/search?q=phytase" title=" phytase "> phytase </a> </p> <a href="https://publications.waset.org/abstracts/26230/growth-performance-and-nutrient-digestibility-of-cirrhinus-mrigala-fingerlings-fed-on-sunflower-meal-based-diet-supplemented-with-phytase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26230.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">300</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">640</span> Climate-Smart Agriculture for Sustainable Maize-Wheat Production: Effects on Crop Productivity, Profitability and Irrigation Water Use</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20K.%20Kakraliya">S.

Coupled with more pumping of groundwater over the years to meet the high irrigation water requirement of the RW system has resulted in over-exploitation of groundwater. Replacement of traditional rice with less water crops such as maize under climate-smart agriculture (CSA) based management (tillage, crop establishment and residue management) practices are required to promote sustainable intensification. Furthermore, inefficient nutrient management practices are responsible for low crop yields and nutrient use efficiencies in maize-wheat (MW) system. A 7-year field experiment was conducted in farmer’s participatory strategic research mode at Taraori, Karnal, India to evaluate the effects of tillage and crop establishment (TCE) methods, residue management, mungbean integration, and nutrient management practices on crop yields, water productivity and profitability of MW system. The main plot treatments included four combinations of TCE, residue and mungbean integration [conventional tillage (CT), conventional tillage with mungbean (CT + MB), permanent bed (PB) and permanent bed with MB (PB + MB] with three nutrient management practices [farmer’s fertilizer practice (FFP), recommended dose of fertilizer (RDF) and site-specific nutrient management (SSNM)] using Nutrient Expert® as subplot treatments. System productivity, water use efficiency (WUE) and net returns under PB + MB were significantly increased by 25–30%, 28–31% and 35–40% compared to CT respectively, during seven years of experimentation. The integration of MB in MW system contributed ~25and ~ 28% increases in system productivity and net returns compared with no MB, respectively. SSNM based nutrient management increased the mean (averaged across 7 yrs) system productivity by 12- 15% compared with FFP. The study revealed that CSA based sustainable intensification (PB + MB) and SSNM approach provided opportunities for enhancing crop productivity, WUE and profitability of the MW system in India. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Conservation%20Agriculture" title="Conservation Agriculture">Conservation Agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=Precision%20water%20and%20nutrient%20management" title=" Precision water and nutrient management"> Precision water and nutrient management</a>, <a href="https://publications.waset.org/abstracts/search?q=Permanent%20beds" title=" Permanent beds"> Permanent beds</a>, <a href="https://publications.waset.org/abstracts/search?q=Crop%20yields" title=" Crop yields"> Crop yields</a> </p> <a href="https://publications.waset.org/abstracts/123908/climate-smart-agriculture-for-sustainable-maize-wheat-production-effects-on-crop-productivity-profitability-and-irrigation-water-use" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/123908.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">132</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">639</span> Assessing Nutrient Concentration and Trophic Status of Brahma Sarover at Kurukshetra, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shailendra%20Kumar%20Patidar">Shailendra Kumar Patidar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Eutrophication of surface water is one of the most widespread environmental problems at present. Large number of pilgrims and tourists visit sacred artificial tank known as “Brahma Sarover” located at Kurukshetra, India to take holy dip and perform religious ceremonies. The sources of pollutants include impurities in feed water, mass bathing, religious offerings and windblown particulate matter. Studies so far have focused mainly on assessing water quality for bathing purpose by using physico-chemical and bacteriological parameters. No effort has been made to assess nutrient concentration and trophic status of the tank to take more appropriate measures for improving water quality on long term basis. In the present study, total nitrogen, total phosphorous and chlorophyll a measurements have been done to assess the nutrient level and trophic status of the tank. The results show presence of high concentration of nutrients and Chlorophyll a indicating mesotrophic and eutrophic state of the tank. Phosphorous has been observed as limiting nutrient in the tank water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Brahma%20Sarover" title="Brahma Sarover">Brahma Sarover</a>, <a href="https://publications.waset.org/abstracts/search?q=eutrophication" title=" eutrophication"> eutrophication</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrients" title=" nutrients"> nutrients</a>, <a href="https://publications.waset.org/abstracts/search?q=trophic%20status" title=" trophic status"> trophic status</a> </p> <a href="https://publications.waset.org/abstracts/12723/assessing-nutrient-concentration-and-trophic-status-of-brahma-sarover-at-kurukshetra-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12723.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">372</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">638</span> Vascular Foramina of the Capitate Bone of the Hand – an Anatomical Study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Latha%20V.%20Prabhu">Latha V.

There exists no literature about the vascular foramina of the capitate bone. The objective of the present study was to investigate the morphology and number of the nutrient foramina in the cadaveric dried capitate bones of the Indian population. Methods: The present study included 59 capitate bones (25 right sided and 34 left sided) which were obtained from the gross anatomy laboratory of our institution. The bones were macroscopically observed for the nutrient foramina and the data was collected with respect to their number. The tabulation of the data and analysis were done. Results: All of our specimens (100%) exhibited the nutrient foramina over the non-articular and articular surfaces. The foramina were observed at the medial, lateral, palmar and dorsal surfaces of the capitate bones. The foramina were ranged from 6 to 23 in each capitate bone. In the medial surface, the foramina ranged from 1 to 6, lateral surface from 0 to 7, the foramina ranged between 0 and 5 in the palmar surface. However most of the foramina were located at the dorsal surface which ranged from 3 to 11. Conclusion: We believe that the present study has provided additional data about the nutrient foramina of the capitate bones. The data is enlightening to the orthopedic surgeon and would help in the hand surgeries. The knowledge about the foramina is also important to the radiologists to prevent the misinterpretation of the findings in the x ray and computed tomogram scan films. The foramina may mimick like erosions and ossicles. The morphological knowledge of the vasculature, their foramina of entry and number is required to understand the concepts in the avascular necrosis of the capitate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=avascular%20necrosis" title="avascular necrosis">avascular necrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=capitate" title=" capitate"> capitate</a>, <a href="https://publications.waset.org/abstracts/search?q=morphology" title=" morphology"> morphology</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20foramen" title=" nutrient foramen"> nutrient foramen</a> </p> <a href="https://publications.waset.org/abstracts/27508/vascular-foramina-of-the-capitate-bone-of-the-hand-an-anatomical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27508.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">343</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">637</span> Yield Enhancement and Reduced Nutrient Removal by Weeds in Winter Irrigated Cotton Using Potassium Salt Based Glyphosate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Viji">N.

The objective of the investigation was to determine the effect of Cocoa Pod Ash (CPA) and Poultry Manure (PM) applied solely and their combined form, as sources of fertilizers on soil properties, leaf nutrient composition, growth and yield of yam. Three soil amendments: CPA, PM (sole forms), CPA and PM (mixture), were applied at 20 t ha<sup>-1</sup> with an inorganic fertilizer (NPK 15-15-15) at 400 kg ha<sup>-1 </sup>as a reference and a natural soil fertility, NSF (control). The five treatments were arranged in a randomized complete block design with three replications. The test soil was slightly acidic, low in organic carbon (OC), N, P, K, Ca and Mg. Results showed that soil amendments significantly increased (p = 0.05) tuber weights and growth of yam, soil and leaf N, P, K, Ca and Mg, soil pH and OC concentrations compared with the NSF (control). The mixture of CPA+PM treatment increased tuber weights of yam by 36%, compared with inorganic fertilizer (NPK) and 19%, compared with PM alone. Sole PM increased tuber weight of yam by 15%, compared with NPK. Sole or mixed forms of soil amendments showed remarkable improvement in soil physical properties, nutrient availability, compared with NPK and the NSF (control). Integrated application of CPA at 10 t ha<sup>-1</sup> + PM at 10 t ha<sup>-1</sup> was the most effective treatment in improving soil physical properties, increasing nutrient availability and yam performance than sole application of any of the fertilizer materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cocoa%20pod%20ash" title="cocoa pod ash">cocoa pod ash</a>, <a href="https://publications.waset.org/abstracts/search?q=leaf%20nutrient%20composition" title=" leaf nutrient composition"> leaf nutrient composition</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry%20manure" title=" poultry manure"> poultry manure</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20properties" title=" soil properties"> soil properties</a>, <a href="https://publications.waset.org/abstracts/search?q=yam" title=" yam"> yam</a> </p> <a href="https://publications.waset.org/abstracts/50710/effects-of-sole-and-integrated-application-of-cocoa-pod-ash-and-poultry-manure-on-soil-properties-and-leaf-nutrient-composition-and-performance-of-white-yam" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50710.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">324</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">635</span> Development and Automation of Medium-Scale NFT Hydroponic Systems: Design Methodology and State of the Art Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oscar%20Armando%20Gonz%C3%A1lez-Marin">Oscar Armando González-Marin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jhon%20F.%20Rodr%C3%ADguez-Le%C3%B3n"> Jhon F.

In addition, the overexploitation of agricultural lands, combined with food and water scarcity, has highlighted the urgent need for sustainable cultivation methods. Hydroponics has emerged as a sustainable farming technique that enables plant cultivation using nutrient solutions without the requirement for traditional soil. Among hydroponic methods, the Nutrient Film Technique (NFT) facilitates plant growth by circulating a nutrient solution continuously. This approach allows the monitoring and precise control of nutritional parameters, with potential for automation and technological integration.

These WRRFs account for about 1% of overall power demand and 2% of total greenhouse gas emissions (GHG) in the United States and contribute for 10 to 15% of the overall nutrient load to surface rivers in the United States. The evolution of densification technologies toward more compact and energy-efficient nutrient removal processes has been impacted by a number of factors. Existing facilities that require capacity expansion or biomass densification for higher treatability within the same footprint are being subjected to more stringent requirements relating to nutrient removal prior to surface water discharge. Densification of activated sludge has received recent widespread interest as a means for achieving process intensification and nutrient removal at WRRFs. At the core of the technology are the aerobic sludge granules where the biological processes occur. There is considerable interest in the prospect of producing granular sludge in continuous (or traditional) activated sludge processes (CAS) or densification of biomass by moving activated sludge flocs to a denser aggregate of biomass as a highly effective technique of intensification. This presentation will provide a fundamental understanding of densification by presenting insights and practical issues. The topics that will be discussed include methods used to generate and retain densified granules; the mechanisms that allow biological flocs to densify; the role that physical selectors play in the densification of biological flocs; some viable ways for managing biological flocs that have become densified; effects of physical selection design parameters on the retention of densified biological flocs and finally some operational solutions for customizing the flocs and granules required to meet performance and capacity targets. In addition, it will present some case studies where biological and physical parameters were used to generate aerobic granular sludge in the continuous flow system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=densification" title="densification">densification</a>, <a href="https://publications.waset.org/abstracts/search?q=aerobic%20granular%20sludge" title=" aerobic granular sludge"> aerobic granular sludge</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20removal" title=" nutrient removal"> nutrient removal</a>, <a href="https://publications.waset.org/abstracts/search?q=intensification" title=" intensification"> intensification</a> </p> <a href="https://publications.waset.org/abstracts/152616/sludge-densification-emerging-and-efficient-way-to-look-at-biological-nutrient-removal-treatment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152616.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">186</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">633</span> Macronutrient Accumulation and Partitioning for Six Wheat Genotypes Grown at Contrasting Nitrogen Supply</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Chakwizira">E.

Teixeira</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Partitioning of macro-nutrients in wheat (Triticum aestivum L.) plant organs have not been extensively studied, particularly for modern genotypes grown under contrasting N supply. Nutrient accumulation and partitioning of phosphorus, potassium, calcium, magnesium and sulphur (P, K, Ca, Mg and S) were determined for six wheat genotypes [12S2-2021, 12S3-3019, 13S3-2026, Discovery, Duchess and Reliance] grown with (200 kg/ha) or without (0 kg/ha) nitrogen (N), in a fully irrigated field experiment in 2017-18 season at Lincoln, New Zealand. Data were collected at three growth stages (GS): tillering (GS21), anthesis (GS60) and grain maturity (GS92). Grain yield varied with both N and genotype; from 6-7.5 t/ha for the 0 kg N/ha crops and 8.1-9.3 t/ha for the 200 kg N/ha treatments. Plant nutrient uptake at maturity responded to both N supply and genotype for all nutrients, except S which did not differ among the genotypes. For example, total P uptake averaged 13.5 (12.4-14.3) kg/ha for the 0 kg N/ha treatments and 17.8 (15.1-19.7) kg/ha when 200 kg N/ha was applied. Similarly, K uptake increased from an average of 23 (21.6-25.3) for the 0 kg N/ha treatments to 34.3 (32.4-40.8) kg/ha when 200 kg N/ha was applied. Similar trends were observed for Ca and Mg. The S content only responded to N supply but not to genotype, increasing from 7.9 kg/ha for the 0 kg N treatments to 12.8 kg/ha when 200 kg N was applied. Relative nutrient content at anthesis compared with those at maturity were 30% for P, 100% for both K and Ca and 34% of Mg. Sulphur content at anthesis decreased 29% with N supply and was highest for genotypes 12S2-2021 compared with the other five genotype. At grain maturity, the ratio of nutrients in grain to total plant nutrient, defined as the nutrient harvest index (NHI) varied with both N supply and genotype. Averaged across treatments, the NHI was 0.96 for P, 0.53 for K, 0.58 for Ca, 0.90 for Mg and 0.85 for S. These results suggest that Ca and K should be provided earlier in the season as there is limited or no uptake after anthesis. These results also show that Ca and K are important for structural functions, while P, Mg and S are remobilised to the grains and become important for quality. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthesis" title="anthesis">anthesis</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20harvests%20index" title=" nutrient harvests index"> nutrient harvests index</a>, <a href="https://publications.waset.org/abstracts/search?q=NHI" title=" NHI"> NHI</a>, <a href="https://publications.waset.org/abstracts/search?q=Triticum%20aestivum%20L." title=" Triticum aestivum L."> Triticum aestivum L.</a> </p> <a href="https://publications.waset.org/abstracts/98953/macronutrient-accumulation-and-partitioning-for-six-wheat-genotypes-grown-at-contrasting-nitrogen-supply" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98953.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">163</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">632</span> Slow and Controlled Release Fertilizer Technology via Application of Plant-available Inorganic Coatings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eugene%20Rybin">Eugene Rybin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reduction of nutrient losses when using mineral fertilizers is a very important and urgent challenge, which is of both economic and environmental significance. This paper shows the production of slow- and controlled release fertilizers through application of inorganic coatings, which make the released nutrients plant-available. The method of production of coated fertilizers with inorganic cover material is an alternative to other methods where polymer coatings are used. The method is based on spraying an aqueous slurry onto the surface of granules with simultaneous drying in drums under certain conditions and subsequent cooling of granules. This method of production of slow- and controlled-release fertilizers is more ecofriendly compared with others because inorganic materials are used to create a membrane. That is why the coating material is definitely biodegradable. There is also shown the effect of these coatings on the properties of fertilizers, as well as on the agrochemical efficiency and nutrient efficiency/ availability to the plants. The agrochemical tests have proved the increase of nutrient efficiency for every nutrient in compound fertilizers (NPK, NPS) for 3 consecutive years by 10-20 % and by 25-28% for urea, as well as an increase in crop yield, by 10-15% in general, and its quality. Moreover, the decrease in caking by almost 70% was proven as well as slowing down the release rate of nutrients from fertilizers. Control of the release rate was achieved by regulation of thickness and contents of coating materials. All of those characteristics were researched according to the standard-used methods. The performed research has developed the fertilizer technology of slow- and controlled release of nutrients through applying of plant-available inorganic coatings. It leads to a better synchronization of nutrient release rate and plants needs, as well as reduces the harmful effects on the environment from the fertilizers applied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=controlled%20release" title="controlled release">controlled release</a>, <a href="https://publications.waset.org/abstracts/search?q=fertilizers" title=" fertilizers"> fertilizers</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrients" title=" nutrients"> nutrients</a>, <a href="https://publications.waset.org/abstracts/search?q=plant-available%20coatings" title=" plant-available coatings"> plant-available coatings</a> </p> <a href="https://publications.waset.org/abstracts/159617/slow-and-controlled-release-fertilizer-technology-via-application-of-plant-available-inorganic-coatings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159617.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">97</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">631</span> A Dynamic Model for Circularity Assessment of Nutrient Recovery from Domestic Sewage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anurag%20Bhambhani">Anurag Bhambhani</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Peter%20Van%20Der%20Hoek"> Jan Peter Van Der Hoek</a>, <a href="https://publications.waset.org/abstracts/search?q=Zoran%20Kapelan"> Zoran Kapelan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The food system depends on the availability of Phosphorus (P) and Nitrogen (N). Growing population, depleting Phosphorus reserves and energy-intensive industrial nitrogen fixation are threats to their future availability. Recovering P and N from domestic sewage water offers a solution. Recovered P and N can be applied to agricultural land, replacing virgin P and N. Thus, recovery from sewage water offers a solution befitting a circular economy. To ensure minimum waste and maximum resource efficiency a circularity assessment method is crucial to optimize nutrient flows and minimize losses. Material Circularity Indicator (MCI) is a useful method to quantify the circularity of materials. It was developed for materials that remain within the market and recently extended to include biotic materials that may be composted or used for energy recovery after end-of-use. However, MCI has not been used in the context of nutrient recovery. Besides, MCI is time-static, i.e., it cannot account for dynamic systems such as the terrestrial nutrient cycles. Nutrient application to agricultural land is a highly dynamic process wherein flows and stocks change with time. The rate of recycling of nutrients in nature can depend on numerous factors such as prevailing soil conditions, local hydrology, the presence of animals, etc. Therefore, a dynamic model of nutrient flows with indicators is needed for the circularity assessment. A simple substance flow model of P and N will be developed with the help of flow equations and transfer coefficients that incorporate the nutrient recovery step along with the agricultural application, the volatilization and leaching processes, plant uptake and subsequent animal and human uptake. The model is then used for calculating the proportions of linear and restorative flows (coming from reused/recycled sources). The model will simulate the adsorption process based on the quantity of adsorbent and nutrient concentration in the water. Thereafter, the application of the adsorbed nutrients to agricultural land will be simulated based on adsorbate release kinetics, local soil conditions, hydrology, vegetation, etc. Based on the model, the restorative nutrient flow (returning to the sewage plant following human consumption) will be calculated. The developed methodology will be applied to a case study of resource recovery from wastewater. In the aforementioned case study located in Italy, biochar or zeolite is to be used for recovery of P and N from domestic sewage through adsorption and thereafter, used as a slow-release fertilizer in agriculture. Using this model, information regarding the efficiency of nutrient recovery and application can be generated. This can help to optimize the recovery process and application of the nutrients. Consequently, this will help to optimize nutrient recovery and application and reduce the dependence of the food system on the virgin extraction of P and N. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circular%20economy" title="circular economy">circular economy</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20substance%20flow" title=" dynamic substance flow"> dynamic substance flow</a>, <a href="https://publications.waset.org/abstracts/search?q=nutrient%20cycles" title=" nutrient cycles"> nutrient cycles</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20recovery%20from%20water" title=" resource recovery from water"> resource recovery from water</a> </p> <a href="https://publications.waset.org/abstracts/140973/a-dynamic-model-for-circularity-assessment-of-nutrient-recovery-from-domestic-sewage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140973.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">197</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">630</span> Site Specific Nutrient Management Need in India Now</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20H.%20Nanher">A.

Therefore, judicious management of all the inputs is essential for the sustainability of such a complex system. Precision agriculture gives farmers the ability to use crop inputs more effectively including fertilizers, pesticides, tillage and irrigation water. More effective use of inputs means greater crop yield and/or quality, without polluting the environment the focus on enhancing the productivity during the Green Revolution coupled with total disregard of proper management of inputs and without considering the ecological impacts, has resulted into environmental degradation. To evaluate a new approach for site-specific nutrient management (SSNM). Large variation in initial soil fertility characteristics and indigenous supply of N, P, and K was observed among Field- and season-specific NPK applications were calculated by accounting for the indigenous nutrient supply, yield targets, and nutrient demand as a function of the interactions between N, P, and K. Nitrogen applications were fine-tuned based on season-specific rules and field-specific monitoring of crop N status. The performance of SSNM did not differ significantly between high-yielding and low-yielding climatic seasons, but improved over time with larger benefits observed in the second year Future, strategies for nutrient management in intensive rice systems must become more site-specific and dynamic to manage spatially and temporally variable resources based on a quantitative understanding of the congruence between nutrient supply and crop demand. The SSNM concept has demonstrated promising agronomic and economic potential. It can be used for managing plant nutrients at any scale, i.e., ranging from a general recommendation for homogenous management of a larger domain to true management of between-field variability. Assessment of pest profiles in FFP and SSNM plots suggests that SSNM may also reduce pest incidence, particularly diseases that are often associated with excessive N use or unbalanced plant nutrition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutrient" title="nutrient">nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=pesticide" title=" pesticide"> pesticide</a>, <a href="https://publications.waset.org/abstracts/search?q=crop" title=" crop"> crop</a>, <a href="https://publications.waset.org/abstracts/search?q=yield" title=" yield "> yield </a> </p> <a href="https://publications.waset.org/abstracts/23288/site-specific-nutrient-management-need-in-india-now" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23288.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">430</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">629</span> Effects of Nitrogen Addition on Litter Decomposition and Nutrient Release in a Temperate Grassland in Northern China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lili%20Yang">Lili Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Jirui%20Gong"> Jirui Gong</a>, <a href="https://publications.waset.org/abstracts/search?q=Qinpu%20Luo"> Qinpu Luo</a>, <a href="https://publications.waset.org/abstracts/search?q=Min%20%20Liu"> Min Liu</a>, <a href="https://publications.waset.org/abstracts/search?q=Bo%20%20Yang"> Bo Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Zihe%20Zhang"> Zihe Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Anthropogenic activities have increased nitrogen (N) inputs to grassland ecosystems. Knowledge of the impact of N addition on litter decomposition is critical to understand ecosystem carbon cycling and their responses to global climate change. The aim of this study was to investigate the effects of N addition and litter types on litter decomposition of a semi-arid temperate grassland during growing and non-growing seasons in Inner Mongolia, northern China, and to identify the relation between litter decomposition and C: N: P stoichiometry in the litter-soil continuum. Six levels of N addition were conducted: CK, N1 (0 g Nm−2 yr−1), N2 (2 g Nm−2 yr−1), N3 (5 g Nm−2 yr−1), N4 (10 g Nm−2 yr−1) and N5 (25 g Nm−2 yr−1). Litter decomposition rates and nutrient release differed greatly among N addition gradients and litter types. N addition promoted litter decomposition of S. grandis, but exhibited no significant influence on L. chinensis litter, indicating that the S. grandis litter decomposition was more sensitive to N addition than L. chinensis. The critical threshold for N addition to promote mixed litter decomposition was 10 -25g Nm−2 yr−1. N addition altered the balance of C: N: P stoichiometry between litter, soil and microbial biomass. During decomposition progress, the L. chinensis litter N: P was higher in N2-N4 plots compared to CK, while the S. grandis litter C: N was lower in N3 and N4 plots, indicating that litter N or P content doesn’t satisfy microbial decomposers with the increasing of N addition. As a result, S. grandis litter exhibited net N immobilization, while L. chinensis litter net P immobilization. Mixed litter C: N: P stoichiometry satisfied the demand of microbial decomposers, showed net mineralization during the decomposition process. With the increasing N deposition in the future, mixed litter would potentially promote C and nutrient cycling in grassland ecosystem by increasing litter decomposition and nutrient release. <p
