sedimentation, ecosystem degradation, and loss of soil nutrients. A study was conducted to evaluate the effect of some organic amendment on sediment yield, splash loss, and runoff of soils of selected parent materials in southeastern Nigeria. A total of 20 locations, five from each of four parent materials namely: Asu River Group (ARG), Bende Ameki Group (BAG), Coastal Plain Sand (CPS) and Falsebedded Sandstone (FBS) were used for the study. Collected soil samples were analyzed with standard methods for the initial soil properties. Rainfall simulation at an intensity of 190 mm hr-1was conducted for 30 minutes on the soil samples at both the initial stage and after amendment to obtain erosion parameters. The influence of parent material on sediment yield, splash loss and runoff based on rainfall simulation was tested for using one way analyses of variance, while the influence of organic material and their combinations were a factorially fitted in a randomized complete block design. The organic amendments include; goat dropping (GD), poultry dropping (PD), municipal solid waste (MSW) and their combinations (COA) applied at four rates of 0, 10, 20 and 30 t ha-1 respectively. Data were analyzed using analyses of variance suitable for a factorial experiment. Significant means were separated using LSD at 5 % probability levels. Result showed significant (p ≤ 0.05) lower values of sediment yield, splash loss and runoff following amendment. For instance, organic amendment reduced sediment yield under wet and dry runs by 12.91 % and 26.16% in Ishiagu, 40.76% and 45.67%, in Bende, 16.17% and 50% in Obinze and 22.80% and 42.35% in Umulolo respectively. Goat dropping and combination of amendment gave the best results in reducing sediment yield. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=organic%20amendment" title="organic amendment">organic amendment</a>, <a href="https://publications.waset.org/abstracts/search?q=parent%20material" title=" parent material"> parent material</a>, <a href="https://publications.waset.org/abstracts/search?q=rainfall%20simulation" title=" rainfall simulation"> rainfall simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20erosion" title=" soil erosion"> soil erosion</a> </p> <a href="https://publications.waset.org/abstracts/69292/the-effects-of-some-organic-amendments-on-sediment-yield-splash-loss-and-runoff-of-soils-of-selected-parent-materials-in-southeastern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69292.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">2566</span> Effects of Soil Organic Amendment Types and Rates on Growth and Yield of Amaranthus cruentus, Southern Guinea Savannah of Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Yussuf%20Abdulmaliq">S.

Soil and manure samples were collected and analysed for physical and chemical components. The experiments were laid out in 3 x 4 factorial in a randomized complete block design (RCBD). Consisting of three (3) levels of soil amendment types (Poultry manure, goat manure and cowdung) and four (4) levels of amendment rates (0, 6, 12 and 18 t ha-1). Data collected include plant height/plant (cm), number of leaves/plant, leaf area/ plant (cm2) at 2, 4, 6 and 8WAT, fresh vegetable yield/plant, fresh vegetable yield/plot and fresh vegetable yield in tons ha-1. The result obtained showed that, Amaranthus cruentus height, number of leaves and leaf area were not significantly affected by the type of organic amendment and rates at 2WAT in 2013 and 2014 cropping seasons. However, at 4, 6 and 8 WAT, significant differences were observed among the types of amendment and their rates. Application of poultry manure as soil amendment supported taller, large number of leaves and wider leaf area, and higher marketable vegetable yield in 2013 and 2014 cropping seasons (Pα 0.05) which was closely followed by goat manure in the two (2) cropping seasons. In addition, the application of 18 t ha-1 was superior to 12, 6 and the control by producing tallest amaranthus plants, higher number of leaves, wider leaf area and higher marketable vegetable yield in 2013 and 2014 cropping seasons (Pα 0.05). In conclusion, the use of 18 t ha-1poultry manure is therefore recommended as soil amendment for Amaranthus cruentus in southern guinea savannah of Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amaranthus%20cruentus" title="Amaranthus cruentus">Amaranthus cruentus</a>, <a href="https://publications.waset.org/abstracts/search?q=cowdung" title=" cowdung"> cowdung</a>, <a href="https://publications.waset.org/abstracts/search?q=goat%20manure" title=" goat manure"> goat manure</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%20amendment" title=" soil amendment"> soil amendment</a> </p> <a href="https://publications.waset.org/abstracts/43684/effects-of-soil-organic-amendment-types-and-rates-on-growth-and-yield-of-amaranthus-cruentus-southern-guinea-savannah-of-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43684.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">2565</span> Photodegradation of Profoxydim Herbicide in Amended Paddy Soil-Water System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Cervantes-Diaz">A.

Sandin-España</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Profoxydim is a post-emergence herbicide belonging to the cyclohexanedione oxime family, used to control weeds in rice crops. The use of soil organic amendments has increased significantly in the last decades, and their effects on the behavior of many herbicides are still unknown. Additionally, it is known that photolysis is an important degradation process to be considered when evaluating the persistence of this family of herbicides in the environment. In this work, the photodegradation of profoxydim in an amended paddy soil-water system with alperujo compost was studied. Photodegradation experiments were carried out under laboratory conditions using simulated solar light (Suntest equipment) in order to evaluate the reaction kinetics of the active substance. The photochemical behavior of profoxydim was investigated in soil with and without alperujo amendment. Furthermore, due to the rice crop characteristics, profoxydim photodegradation in water in contact with these types of soils was also studied. Determination of profoxydim degradation kinetics was performed by High-Performance Liquid Chromatography with Diode-Array Detection (HPLC-DAD). Furthermore, we followed the evolution of resulting transformation by-products, and their tentative identification was achieved by mass spectrometry. All the experiments allowed us to fit the data of profoxydim photodegradation to a first-order kinetic. Photodegradation of profoxydim was very rapid in all cases. The half-lives in aqueous matrices were in the range of 86±0.3 to 103±0.5 min. The addition of alperujo amendment to the soil produced an increase in the half-life from 62±0.2 min (soil) to 75±0.3 min (amended soil). In addition, a comparison to other organic amendments was also performed. Results showed that the presence of the organic amendment retarded the photodegradation in paddy soil and water. Regarding degradation products, the main process involved was the cleavage of the oxime moiety giving rise to the formation of the corresponding imine compound. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=by-products" title="by-products">by-products</a>, <a href="https://publications.waset.org/abstracts/search?q=herbicide" title=" herbicide"> herbicide</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20amendment" title=" organic amendment"> organic amendment</a>, <a href="https://publications.waset.org/abstracts/search?q=photodegradation" title=" photodegradation"> photodegradation</a>, <a href="https://publications.waset.org/abstracts/search?q=profoxydim" title=" profoxydim"> profoxydim</a> </p> <a href="https://publications.waset.org/abstracts/164086/photodegradation-of-profoxydim-herbicide-in-amended-paddy-soil-water-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164086.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">79</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">2564</span> The Road to Abolition of Death Penalty in China: With the Perspective of the Ninth Amendment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huang%20Gui">Huang Gui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper supplies some possible approaches of the death penalty reform in China basic on the analyzing the reformation conducted by the Ninth Amendment. There now are 46 crimes punishable by death, and this penalty still plays a significant role in the criminal punishment structure. In order to abolish entirely the death penalty in Penal Code, the legislature of China should gradually abolish the death penalty for the nonviolent crimes and then for the nonlethal violent crimes and finally for the lethal violent crimes. In the case where the death penalty has not yet been abolished completely, increasing the applicable conditions of suspension of execution of death penalty and reducing the scope of applicable objects (elderly defendant and other kinds of special objects) of death penalty would be an effective road to control and limit the use of death penalty in judicial practice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=death%20penalty" title="death penalty">death penalty</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20eighth%20amendment" title=" the eighth amendment"> the eighth amendment</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20ninth%20amendment" title=" the ninth amendment"> the ninth amendment</a>, <a href="https://publications.waset.org/abstracts/search?q=suspension%20of%20execution%20of%20death" title=" suspension of execution of death"> suspension of execution of death</a>, <a href="https://publications.waset.org/abstracts/search?q=immediate%20execution%20of%20death" title=" immediate execution of death"> immediate execution of death</a>, <a href="https://publications.waset.org/abstracts/search?q=China" title=" China"> China</a> </p> <a href="https://publications.waset.org/abstracts/45577/the-road-to-abolition-of-death-penalty-in-china-with-the-perspective-of-the-ninth-amendment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45577.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">478</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">2563</span> Physical and Chemical Properties during Home Composting of Municipal Organic Solid Waste in Jordan and Production of Organic Fertilizer</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Munir%20Rusan">Munir Rusan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Municipal waste management (MWM) represents a cornerstone in the effort to preserve the environment, which guarantees a healthy living environment for communities. MWM is directly affected by population growth and population density, urbanization, and tourism. In Jordan, MWM is currently managed by transferring and dumping waste into landfills. Landfills are mostly saturated and cannot receive any more waste. Besides, the organic waste, which accounts for 50% of municipal waste, will be naturally fermented in the landfills creating an unpleasant odor and emits greenhouse gases as well as generate organic leachates that are harmful to the environment. Organic waste can be aerobically composted and generate organic fertilizer called compost. Compost is very beneficial to soil and plant growth and, in general, to the ecosystem. Home composting is very common in most developed countries, but unfortunately, in developing countries such as Jordan, such an approach is not practiced and is not even socially well acceptable. The objective of this study was to evaluate the physical and chemical properties of home composting materials and to produce compost for further use as a soil amendment. The effect of compost soil application on the soil-plant system was evaluated. The soil application of the compost resulted in enhancing soil organic matter and soil N, P, and K content. The plant growth was also improved quantitatively and qualitatively. It was concluded that composting of municipal organic solid waste and soil application of the compost has a significant positive impact on the environment and soil-plant productivity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=composting" title="composting">composting</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20solid%20waste" title=" organic solid waste"> organic solid waste</a>, <a href="https://publications.waset.org/abstracts/search?q=soil" title=" soil"> soil</a>, <a href="https://publications.waset.org/abstracts/search?q=plant" title=" plant"> plant</a> </p> <a href="https://publications.waset.org/abstracts/164293/physical-and-chemical-properties-during-home-composting-of-municipal-organic-solid-waste-in-jordan-and-production-of-organic-fertilizer" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164293.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">82</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">2562</span> The Problems with the Amendment of a Living Trust in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rika%20van%20Zyl">Rika van Zyl</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It was ruled that an inter vivos trust must be amended according to the rules of the stipulatio alteri, or ‘contract in favour of a third party’, that South African adopted from its Roman-Dutch common law. The application of the principles of the stipulatio alteri on the inter vivos trust has developed in case law to imply that once the beneficiary has accepted benefits, he becomes a party to the contract. This consequently means that he must consent to any amendments that the trustees want to make. This poses practical difficulties such as finding all the beneficiaries that have accepted to sign the amendment that the trustees would want to circumvent in administering the trust. One of the questions relating to this issue is, however, whether the principles of the stipulatio alteri are correctly interpreted and consequently applied to the inter vivos trust to mean that the beneficiaries who accepted must consent to any amendment. The subsequent question relates to the rights the beneficiary receives upon acceptance. There seems to be a different view of what a vested right or a contingent right of the beneficiary means in relation to the inter vivos trust. These rights also have an impact on the amendment of a trust deed. Such an investigation and refining of the interpretation of the stipulatio alteri’s application on the inter vivos trust may result in solutions to circumvent the adverse effects of getting the beneficiary’s consent for amendments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inter%20vivos%20trust" title="inter vivos trust">inter vivos trust</a>, <a href="https://publications.waset.org/abstracts/search?q=stipulatio%20alteri" title=" stipulatio alteri"> stipulatio alteri</a>, <a href="https://publications.waset.org/abstracts/search?q=amendment" title=" amendment"> amendment</a>, <a href="https://publications.waset.org/abstracts/search?q=beneficiary%20rights" title=" beneficiary rights"> beneficiary rights</a> </p> <a href="https://publications.waset.org/abstracts/96582/the-problems-with-the-amendment-of-a-living-trust-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/96582.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">170</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">2561</span> Influence of Environment-Friendly Organic Wastes on the Properties of Sandy Soil under Growing Zea mays L. in Arid Regions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Rashad">Mohamed Rashad</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Hafez"> Mohamed Hafez</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Emran"> Mohamed Emran</a>, <a href="https://publications.waset.org/abstracts/search?q=Emad%20Aboukila"> Emad Aboukila</a>, <a href="https://publications.waset.org/abstracts/search?q=Ibrahim%20Nassar"> Ibrahim Nassar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Environment-friendly organic wastes of Brewers' spent grain, a byproduct of the brewing process, have recently used as soil amendment to improve soil fertility and plant production. In this work, treatments of 1% (T1) and 2% (T2) of spent grains, 1% (C1) and 2% (C2) of compost and mix of both sources (C1T1) were used and compared to the control for growing <em>Zea mays </em>L. on sandy soil under arid Mediterranean climate. Soils were previously incubated at 65% saturation capacity for a month. The most relevant soil physical and chemical parameters were analysed. Water holding capacity and soil organic matter (OM) increased significantly along the treatments with the highest values in T2. Soil pH decreased along the treatments and the lowest pH was in C1T1. Bicarbonate decreased by 69% in C1T1 comparing to control. Total nitrogen (TN) and available P varied significantly among all treatments and T2, C1T1 and C2 treatments increased 25, 17 and 11 folds in TN and 1.2, 0.6 and 0.3 folds in P, respectively related to control. Available K showed the highest values in C1T1. Soil micronutrients increased significantly along all treatments with the highest values in T2. After corn germination, significant variation was observed in the velocity of germination coefficients (VGC) among all treatments in the order of C1T1>T2>T1>C2>C1>control. The highest records of final germination and germination index were in C1T1 and T2. The spent grains may compensate deficiencies of macro and micronutrients in newly reclaimed sandy soils without adverse effects to sustain crop production with a rider that excessive or continuous use need to be circumvented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corn%20and%20squash%20germination" title="corn and squash germination">corn and squash germination</a>, <a href="https://publications.waset.org/abstracts/search?q=environmentally%20friendly%20organic%20wastes" title=" environmentally friendly organic wastes"> environmentally friendly organic wastes</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20carbon%20sequestration" title=" soil carbon sequestration"> soil carbon sequestration</a>, <a href="https://publications.waset.org/abstracts/search?q=spent%20grains%20as%20soil%20amendment" title=" spent grains as soil amendment"> spent grains as soil amendment</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20holding%20capacity" title=" water holding capacity"> water holding capacity</a> </p> <a href="https://publications.waset.org/abstracts/51641/influence-of-environment-friendly-organic-wastes-on-the-properties-of-sandy-soil-under-growing-zea-mays-l-in-arid-regions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/51641.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">509</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">2560</span> Poultry Manure and Its Derived Biochar as a Soil Amendment for Newly Reclaimed Sandy Soils under Arid and Semi-Arid Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=W.%20S.%20Mohamed">W.

Hammam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Sandy soils under arid and semi-arid conditions are characterized by poor physical and biochemical properties such as low water retention, rapid organic matter decomposition, low nutrients use efficiency, and limited crop productivity. Addition of organic amendments is crucial to develop soil properties and consequently enhance nutrients use efficiency and lessen organic carbon decomposition. Two years field experiments were developed to investigate the feasibility of using poultry manure and its derived biochar integrated with different levels of N fertilizer as a soil amendment for newly reclaimed sandy soils in Western Desert of El-Minia Governorate, Egypt. Results of this research revealed that poultry manure and its derived biochar addition induced pronounced effects on soil moisture content at saturation point, field capacity (FC) and consequently available water. Data showed that application of poultry manure (PM) or PM-derived biochar (PMB) in combination with inorganic N levels had caused significant changes on a range of the investigated sandy soil biochemical properties including pH, EC, mineral N, dissolved organic carbon (DOC), dissolved organic N (DON) and quotient DOC/DON. Overall, the impact of PMB on soil physical properties was detected to be superior than the impact of PM, regardless the inorganic N levels. In addition, the obtained results showed that PM and PM application had the capacity to stimulate vigorous growth, nutritional status, production levels of wheat and sorghum, and to increase soil organic matter content and N uptake and recovery compared to control. By contrast, comparing between PM and PMB at different levels of inorganic N, the obtained results showed higher relative increases in both grain and straw yields of wheat in plots treated with PM than in those treated with PMB. The interesting feature of this research is that the biochar derived from PM increased treated sandy soil organic carbon (SOC) 1.75 times more than soil treated with PM itself at the end of cropping seasons albeit double-applied amount of PM. This was attributed to the higher carbon stability of biochar treated sandy soils increasing soil persistence for carbon decomposition in comparison with PM labile carbon. It could be concluded that organic manures applied to sandy soils under arid and semi-arid conditions are subjected to high decomposition and mineralization rates through crop seasons. Biochar derived from organic wastes considers as a source of stable carbon and could be very hopeful choice for substituting easily decomposable organic manures under arid conditions. Therefore, sustainable agriculture and productivity in newly reclaimed sandy soils desire one high rate addition of biochar derived from organic manures instead of frequent addition of such organic amendments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biochar" title="biochar">biochar</a>, <a href="https://publications.waset.org/abstracts/search?q=dissolved%20organic%20carbon" title=" dissolved organic carbon"> dissolved organic carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=N-uptake" title=" N-uptake"> N-uptake</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry" title=" poultry"> poultry</a>, <a href="https://publications.waset.org/abstracts/search?q=sandy%20soil" title=" sandy soil"> sandy soil</a> </p> <a href="https://publications.waset.org/abstracts/98788/poultry-manure-and-its-derived-biochar-as-a-soil-amendment-for-newly-reclaimed-sandy-soils-under-arid-and-semi-arid-conditions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98788.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">145</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">2559</span> Effects of Application of Rice Husk Charcoal-Coated Urea and Rice Straw Compost on Growth, Yield, and Properties of Lowland Rice</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20A.%20S.%20Gamage">D.

The application of inorganic fertilizer has become a burden to the country. The excessive application of organic and inorganic fertilizers can potentially lead to deterioration of the quality of water. In mixing both urea and rice husk charcoal and rice straw compost in soils causes a slow release of nitrogen fertilizer, thus reducing the cost of importations of nitrogen based fertilizers per unit area of cultivation. Objective of this study was to evaluate rice husk charcoal coated urea as a slow releasing fertilizer and compare the total N,P, K, organic matter in soil and yield of rice production. Five treatments were used for twenty pots (pot size 30 cm diameter and 45 cm height) each replicated four times as: inorganic fertilizer only (Urea, TSP and MOP) (Treatment 1); rice husk charcoal coated urea, TSP and MOP (Treatment 2); inorganic fertilizer (Urea, TSP and MOP) with rice straw compost only (Treatment 3); rice husk charcoal urea, TSP and MOP with rice straw compost (Treatment 4); and no fertilizer as the control (Treatment 5). Rice grain yield was significantly higher in treatment 4 where rice husk charcoal coated urea, TSP and MOP with rice straw compost. The lowest yield was observed in control (treatment 5). The lower the value of the nitrogen to phosphorous ratio in soil, it indicates higher uptake of phosphorous. Charcoal can be used as a soil amendment and organic fertilizer, but adjustment of pH was required at high application rates. K content of soil of treatment 3 and 4 were the highest with compared to the treatment 1. Rice husk charcoal coated urea can potentially be used as a slow releasing nitrogen fertilizer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=charcoal" title="charcoal">charcoal</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20husk" title=" rice husk"> rice husk</a>, <a href="https://publications.waset.org/abstracts/search?q=nitrogen%20to%20phosphorous%20ratio" title=" nitrogen to phosphorous ratio"> nitrogen to phosphorous ratio</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20amendment" title=" soil amendment"> soil amendment</a> </p> <a href="https://publications.waset.org/abstracts/35609/effects-of-application-of-rice-husk-charcoal-coated-urea-and-rice-straw-compost-on-growth-yield-and-properties-of-lowland-rice" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35609.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">308</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">2558</span> Combating Illegal Logging in Malaysia: Policies and Strategies under National Forestry Act (NFA) 1984</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20Nur%20Haniff%20Mohd%20Noor">Muhammad Nur Haniff Mohd Noor</a>, <a href="https://publications.waset.org/abstracts/search?q=Rokiah%20Kadir"> Rokiah Kadir</a>, <a href="https://publications.waset.org/abstracts/search?q=Suriyani%20Muhamad"> Suriyani Muhamad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The National Forestry Act (NFA) 1984 is the primary forest law that regulates forest-related activities in Peninsular Malaysia. In the 1990s, abundance of illegal logging cases have called for legislative reform of the NFA 1984. As a result, NFA 1984 was amended in 1993 with the principal goal of controlling illegal forest encroachment in the forms of illegal logging, unauthorized harvesting, unlicensed forest settlement and other forms of unlawful activities. At a conceptual level, this paper discusses the policies and strategies implemented under the NFA 1984 (Amendment 1993) that are dedicated to overcome illegal logging. Then, the policies and strategies employed are reviewed and evaluated. Next, this paper conceptually discusses the loopholes of NFA 1984 (Amendment 1993) in relation to aspects where the regulation is considered insufficient to curb illegal logging. In the final section, vital actions and suggested improvements to improve the overall effectiveness of NFA 1984 (Amendment 1993) are examined. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=forest%20law%20and%20regulation" title="forest law and regulation">forest law and regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=illegal%20logging" title=" illegal logging"> illegal logging</a>, <a href="https://publications.waset.org/abstracts/search?q=National%20Forestry%20Act%201984" title=" National Forestry Act 1984"> National Forestry Act 1984</a>, <a href="https://publications.waset.org/abstracts/search?q=NFA%201984" title=" NFA 1984"> NFA 1984</a>, <a href="https://publications.waset.org/abstracts/search?q=Amendment%201993" title=" Amendment 1993"> Amendment 1993</a>, <a href="https://publications.waset.org/abstracts/search?q=Peninsular%20Malaysia" title=" Peninsular Malaysia"> Peninsular Malaysia</a> </p> <a href="https://publications.waset.org/abstracts/88446/combating-illegal-logging-in-malaysia-policies-and-strategies-under-national-forestry-act-nfa-1984" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88446.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">260</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">2557</span> A Comparative Analysis of the Private and Social Benefit-Cost Ratios of Organic and Inorganic Rice Farming: Case Study of Smallholder Farmers in the Aveyime Community, Ghana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jerome%20E.%20Abiemo">Jerome E.

In the past, rice farmers applied organic pesticides to control pests, and compost as a soil amendment to improve fertility and productivity. However, the introduction of chemical pesticides and fertilizers have led many farmers to convert to inorganic system of rice production, without considering the social costs (e.g. groundwater contamination and health costs) related to the use of pesticides. The study estimates and compares the private and social BCRs of organic and inorganic systems of rice production. Both stratified and simple random sampling techniques were employed to select 300 organic and inorganic rice farmers and 50 pesticide applicators. The respondents were interviewed with pre-tested questionnaires. The Contingent Valuation Method (CVM) which elucidates organic farmers` Willingness-to-Pay (WTP) was employed to estimate the cost of groundwater contamination. The Cost of Illness (COI) analysis was used to estimate the health cost of pesticide-induced poisoning of applicators. The data collated, was analyzed with the aid of Microsoft excel. The study found that high private benefit (e.g. increase in farm yield and income) was the most influential factor for the rapid adoption of pesticides among rice farmers. The study also shows that the social costs of inorganic rice production were high. As such the social BCR of inorganic farming (0.2) was low as compared to organic farming (0.7). Based on the results, it was recommended that government should impose pesticide environmental tax, review current agricultural policies to favour organic farming and promote extension education to farmers on pesticide risk, to ensure agricultural and environmental sustainability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=benefit-cost-ratio%20%28BCR%29" title="benefit-cost-ratio (BCR)">benefit-cost-ratio (BCR)</a>, <a href="https://publications.waset.org/abstracts/search?q=inorganic%20farming" title=" inorganic farming"> inorganic farming</a>, <a href="https://publications.waset.org/abstracts/search?q=pesticides" title=" pesticides"> pesticides</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20cost" title=" social cost"> social cost</a> </p> <a href="https://publications.waset.org/abstracts/68341/a-comparative-analysis-of-the-private-and-social-benefit-cost-ratios-of-organic-and-inorganic-rice-farming-case-study-of-smallholder-farmers-in-the-aveyime-community-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68341.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">478</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">2556</span> Factors Influencing the Resistance of the Purchase of Organic Food and Market Education Process in Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fety%20Nurlia%20Muzayanah">Fety Nurlia Muzayanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Arif%20Imam%20Suroso"> Arif Imam Suroso</a>, <a href="https://publications.waset.org/abstracts/search?q=Mukhamad%20Najib"> Mukhamad Najib</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The market share of organic food in Indonesia just reaches 0.5-2 percents from the entire of agricultural products.

However, the price of farmyard manure, the organic amendment typically applied to many arid and semi-arid soils has highly increased in the last years. To investigate at field scale whether cheap, highly available organic amendments, such as sewage sludge compost and municipal solid waste compost, may be acceptable as substitutes for farmyard manure is therefore of great interest. A field plots experiment was carried out to assess the effects of a single application of three organic amendments on soil fertility, distribution of trace elements and on barley yield. Municipal solid waste compost (MSWC), farmyard manure (FYM) and sewage sludge compost (SSC) were applied at rates of 0, 20, 40 and 60 t ha⁻¹, and barley was cultivated in two consecutive years. Plant samples and soils were collected for laboratory analyses after two consecutive harvests. Compared with unamended soil, the application of the three organic residues improved the fertility of the topsoil, showing a significant dose-dependent increase of TOC, N, P contents up to the highest dose of 60 t ha⁻¹ (0.74%, 0.06% and 40 mg kg⁻¹, respectively). The enhancement of soil nutrient status impacted positively on grain yield (up to 51%). The distribution of trace elements in the soil, analysed by a sequential extraction procedure, revealed that the MSWC increased the acid-extractable Co and Cu and reducible Ni, while SSC increased reducible Co and Ni and oxidisable Cu, relative to the control soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=municipal%20solid%20waste%20compost" title="municipal solid waste compost">municipal solid waste compost</a>, <a href="https://publications.waset.org/abstracts/search?q=sewage%20sludge%20compost" title=" sewage sludge compost"> sewage sludge compost</a>, <a href="https://publications.waset.org/abstracts/search?q=fertility" title=" fertility"> fertility</a>, <a href="https://publications.waset.org/abstracts/search?q=trace%20metals" title=" trace metals"> trace metals</a> </p> <a href="https://publications.waset.org/abstracts/159940/monitoring-soil-organic-amendments-under-arid-climate-evolution-of-soil-quality-and-of-two-consecutive-barley-crops" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159940.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">88</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">2554</span> Consumer Attitude and Purchase Intention towards Organic Food: Insights from Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muneshia%20Maheshwar">Muneshia Maheshwar</a>, <a href="https://publications.waset.org/abstracts/search?q=Kanwal%20Gul"> Kanwal Gul</a>, <a href="https://publications.waset.org/abstracts/search?q=Shakira%20%20Fareed"> Shakira Fareed</a>, <a href="https://publications.waset.org/abstracts/search?q=Ume-Amama%20Areeb%20Gul"> Ume-Amama Areeb Gul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Organic food is commonly known for its healthier content without the use of pesticides, herbicides, inorganic fertilizers, antibiotics and growth hormones.

Field and pot experiments were conducted to assess soil microbial activities, growth and yield of tomato varieties in response to 4 rates of composted plant and animal residues. The compost rates were 0, 5, 10 and 20 t ha-1, and improved Ibadan and Ibadan local constituted the varieties. Fungi population, microbial biomass nitrogen, cellulase and proteinase activities were significantly higher (P≤ 0.05) at the rhizosphere of the local variety than that of improved variety. This led to a significantly higher number of branches, plant height, leaf area, number of fruits and less days to maturity in the local variety. Furthermore, compost-amended soil had significantly higher microbial populations, microbial biomass N, P and C, enzyme activities, soil N, P and organic carbon than control, but amendment of 20 t ha-1 gave significantly higher values than other compost rates. Consequently, growth parameters and tissue N significantly increased in all compost treatments while dry matter yield and weight of fruits were significantly higher in soil amended with 20 t ha-1. Correlation analysis showed that microbial activities at 6 weeks after transplanting (6 WAT) were more consistently and highly correlated with growth and yield parameters. It was concluded that microbial activities could be optimized to improve the yield of the two tomato varieties in an organic production system, through the application of compost, particularly at 20 t ha-1. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=compost" title="compost">compost</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20activities" title=" microbial activities"> microbial activities</a>, <a href="https://publications.waset.org/abstracts/search?q=microbial%20contribution" title=" microbial contribution"> microbial contribution</a>, <a href="https://publications.waset.org/abstracts/search?q=tomato%20growth%20and%20yield" title=" tomato growth and yield"> tomato growth and yield</a> </p> <a href="https://publications.waset.org/abstracts/81437/contributions-of-microbial-activities-to-tomato-growth-and-yield-under-an-organic-production-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81437.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">265</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">2552</span> Consumer Behavior and Knowledge on Organic Products in Thailand</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Warunpun%20Kongsom">Warunpun Kongsom</a>, <a href="https://publications.waset.org/abstracts/search?q=Chaiwat%20Kongsom"> Chaiwat Kongsom</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study was to investigate the awareness, knowledge and consumer behavior towards organic products in Thailand. For this study, a purposive sampling technique was used to identify a sample group of 2,575 consumers over the age of 20 years who intended or made purchases from 1) green shops; 2) supermarkets with branches; and, 3) green markets. A questionnaire was used for data collection across the country. Descriptive statistics were used for data analysis. The results showed that more than 92% of consumers were aware of organic agriculture, but had less knowledge about it. More than 60% of consumers knew that organic agriculture production and processing did not allow the use of chemicals. And about 40% of consumers were confused between the food safety logo and the certified organic logo, and whether GMO was allowed in organic agriculture practice or not. In addition, most consumers perceived that organic agricultural products, good agricultural practice (GAP) products, agricultural chemicals free products, and hydroponic vegetable products had the same standard. In the view of organic consumers, the organic Thailand label was the most seen and reliable among various organic labels. Less than 3% of consumers thought that the International Federation of Organic Agriculture Movements (IFOAM) Global Organic Mark (GOM) was the most seen and reliable. For the behaviors of organic consumers, they purchased organic products mainly at the supermarket and green shop (55.4%), one to two times per month, and with a total expenditure of about 200 to 400 baht each time. The main reason for buying organic products was safety and free from agricultural chemicals. The considered factors in organic product selection were price (29.5%), convenience (22.4%), and a reliable certification system (21.3%). The demands for organic products were mainly rice, vegetables and fruits. Processed organic products were relatively small in quantity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consumer%20behavior" title="consumer behavior">consumer behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=consumer%20knowledge" title=" consumer knowledge"> consumer knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20products" title=" organic products"> organic products</a>, <a href="https://publications.waset.org/abstracts/search?q=Thailand" title=" Thailand"> Thailand</a> </p> <a href="https://publications.waset.org/abstracts/47388/consumer-behavior-and-knowledge-on-organic-products-in-thailand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47388.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">296</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">2551</span> An Organic Dye-Based Staining for Plant DNA</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Beg%C3%BCm%20Terzi">Begüm Terzi</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96zlem%20Ate%C5%9F%20S%C3%B6nmezo%C4%9Flu"> Özlem Ateş Sönmezoğlu</a>, <a href="https://publications.waset.org/abstracts/search?q=Kerime%20%C3%96zkay"> Kerime Özkay</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmet%20Y%C4%B1ld%C4%B1r%C4%B1m"> Ahmet Yıldırım</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In plant biotechnology, electrophoresis is used to detect nucleic acids.

There is a need to develop a biologically-based method of soil disinfestation that facilitates profitable and sustainable production without the use of chemical fumigants. Anaerobic Soil Disinfestation (ASD), as well know as biodisinfestation, has been shown to control a wide range of soil-borne pathogens and nematodes in numerous crop production systems. This method implies soil wetting, incorporation of a easily decomposable carbon-rich organic amendment and covering with plastic film for several weeks. ASD with rapeseed cake (var. Tocatta, a glucosinolates-free variety) used as C-source was assayed in spring 2014, before the pepper crop establishment. The field experiment was conducted at the Agricultural Research Centre Finca La Orden (Southwestern Spain) and the treatments were: rapeseed cake (RCP); rapeseed cake without plastic cover (RC); control non-amendment (CP) and control non-amendment without plastic cover (C). The experimental design was a randomized complete block design with four replicates and a plot size of 5 x 5 m. On 26 March, rapeseed cake (1 kg·m-2) was incorporated into the soil with a rotovator. Biological probes with the inoculum were buried at 15 and 30-cm depth (biological probes were previously prepared with 100 g of disinfected soil inoculated with chlamydospores (chlam) of P. nicotianae P13 isolate [100 chlam·g-1 of soil] and wrapped in agryl cloth). Sprinkler irrigation was run until field capacity and the corresponding plots were covered with transparent plastic (PE 0.05 mm). On 6 May plastics were removed, the biological probes were dug out and a bioassay was established. One pepper seedling at the 2 to 4 true-leaves stage was transplanted in the soil from each biological probe. Plants were grown in a climatic chamber and disease symptoms were recorded every week during 2 months. Fragments of roots and crown of symptomatic plants were analyzed on NARPH media and soil from rizospheres was analyzed using carnation petals as baits. Results of “survival” were expressed as the percentage of soil samples where P. nicotianae was detected and results of “infectivity” were expressed as the percentage of diseased plants. No differences were detected in deep effect. Infectivity of P. nicotianae chlamydospores was successfully reduced in RCP treatment (4.2% of infectivity) compared with the controls (41.7% of infectivity). The pattern of survival was similar to infectivity observed by the bioassay: 21% of survival in RCP; 79% in CP; 83% in C and 87% in RC. Although ASD may be an effective alternative to chemical fumigants to pest management, more research is necessary to show their impact on the microbial community and chemistry of the soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biodisinfestation" title="biodisinfestation">biodisinfestation</a>, <a href="https://publications.waset.org/abstracts/search?q=BSD" title=" BSD"> BSD</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20fumigant%20alternatives" title=" soil fumigant alternatives"> soil fumigant alternatives</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20amendments" title=" organic amendments"> organic amendments</a> </p> <a href="https://publications.waset.org/abstracts/47517/anaerobic-soil-disinfestation-feasible-alternative-to-soil-chemical-fumigants" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47517.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">217</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">2549</span> Combined Application of Rice-Straw Biochar and Poultry Manure Promotes Nutrient Uptake and Yield of Capsicum Frutescens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fawibe%20O.%20O.">Fawibe O.

The experiment was a randomized complete block design with five replicates. Treatments were 10 t/ha biochar (BC), 5 t/ha biochar + 5 t/ha poultry manure (BC+PM), 10 t/ha poultry manure (PM), and no amendment as the control (NA ). Parameters determined were fruit yield, aboveground biomass, macro and micro nutrients in leaves, antinutrients content, and pigments (chlorophyll a, chlorophyll b, and carotenoids) concentration. Data were analysed with one-way analysis of variance, while means were separated using Duncan’s Multiple Range Test at p<0.05. Soil amended with PM increased the nitrogen content of C. frutescens leaves by 40.9%, while polyphenol and phytic acid were reduced by 20.5% and 29.2%, respectively, compared with NA. Moreover, PM increased chlorophyll a and chlorophyll b by 91.9% and 16.4%, whereas proline was reduced by 31.3% compared with NA. However, PM and BC+PM had comparable influence on pigments, nutrients and antinutrients contents of C. frutescens. BC+PM significantly increased yield and aboveground biomass of C. frutescens by 52.9% and 99.2%, respectively, compared with NA. BC had no significant influence on the yield and nutrient uptake of C. frutescens compared with NA. In conclusion, sole application of poultry manure or combined with rice-straw biochar increased yield and nutrients availability in the leaves of C. frutescens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=capsicum%20frutescens" title="capsicum frutescens">capsicum frutescens</a>, <a href="https://publications.waset.org/abstracts/search?q=biochar" title=" biochar"> biochar</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=poultry%20manure" title=" poultry manure"> poultry manure</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20amendment" title=" organic amendment"> organic amendment</a> </p> <a href="https://publications.waset.org/abstracts/164922/combined-application-of-rice-straw-biochar-and-poultry-manure-promotes-nutrient-uptake-and-yield-of-capsicum-frutescens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164922.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">101</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">2548</span> Utilizing Mahogany (Swietenia Macrophylla) Fruits, Leaves, and Branches as Biochar for Soil Amendment in Okra (Abelmoschus Esculentus) Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ayaka%20A.%20Matsuo">Ayaka A.

In a more straightforward approach, our results show that biochar derived from isn't just a minor player but emerges as a key contributor to our study. This finding holds profound implications, as it highlights the material significance of biochar derived from Mahogany (Swietenia macrophylla) fruits, leaves, and branches in shaping the outcomes. The importance of this discovery lies in its contribution to an enhanced comprehension of the overall effects of biochar on the variables explored in our investigation. Notably, the positive changes observed in height, number of leaves, and width of leaves in okra plants further support the premise that the incorporation of biochar improves soil quality. These findings provide valuable insights for agricultural practices, suggesting that biochar derived from Mahogany (Swietenia macrophylla) fruits, leaves, and branches holds promise as a sustainable soil amendment with positive implications for plant growth. The statistical results from multivariate tests serve to solidify the conclusion that biochar plays a pivotal role in driving the observed outcomes in our study. In essence, this research not only sheds light on the potential of mahogany fruit-derived biochar but also emphasizes its significance in fostering healthier soil conditions and, consequently, enhanced plant growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20amendment" title="soil amendment">soil amendment</a>, <a href="https://publications.waset.org/abstracts/search?q=biochar" title=" biochar"> biochar</a>, <a href="https://publications.waset.org/abstracts/search?q=mahogany" title=" mahogany"> mahogany</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20health" title=" soil health"> soil health</a> </p> <a href="https://publications.waset.org/abstracts/183179/utilizing-mahogany-swietenia-macrophylla-fruits-leaves-and-branches-as-biochar-for-soil-amendment-in-okra-abelmoschus-esculentus-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/183179.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">75</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">2547</span> Simulation and Characterization of Organic Light Emitting Diodes and Organic Photovoltaics Using Physics Based Tool</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20A.%20Shahul%20Hameed">T.

They can be removed by various physiochemical methods but are costly and responsible for additional environmental problems. Bioremediation that exploits plants and their associated microbes have been referred as cost effective and environmental friendly technique. In this study, a pot experiment was conducted in a greenhouse to evaluate the potential of Celosia cristata and effects of bacteria, Pseudomonas japonica, and organic amendment moss/compost on tolerating/accumulating heavy metals. Two weeks old seedlings were transferred to soil in pots, and after four weeks they were inoculated with bacterial strain, while after growth of six weeks they were watered with a metal containing synthetic wastewater and were harvested after a growth period of nine weeks. After harvesting, morphological and physiological parameters and metal content of plants were measured. The results showed highest plant growth and biomass production in case of organic amendments while highest metal uptake has been found in non-amended pots. Positive controls have shown highest Pb uptake of 2900 mg/kg DW, while P. japonica amended pots have shown highest Cd, Cr, Ni and Cu uptake of 963.53, 1481.17, 1022.01 and 602.17 mg/kg DW, respectively. In conclusion organic amendments have strong impacts on growth enhancement while P. japonica enhances metal translocation and accumulation to aerial parts with little significant involvement in plant growth. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ornamental%20plants" title="ornamental plants">ornamental plants</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20microbe%20interaction" title=" plant microbe interaction"> plant microbe interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=amendments" title=" amendments"> amendments</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteria" title=" bacteria"> bacteria</a> </p> <a href="https://publications.waset.org/abstracts/71841/influence-of-pseudomonas-japonica-on-growth-and-metal-tolerance-of-celosia-cristata-l" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/71841.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">294</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">2543</span> State Coercion and Social Movements: Legacy of Authoritarian Regime</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyun-Ji%20Choi">Hyun-Ji Choi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to examine the meaning of ‘state’ as a monopoly of violence, in regard with South Korean democratic transition. Since institutional democratization in 1987, it is conventionally known that governmental authority has exercised its power through law and police force, rather than inclusive or private violence. In other words, 1987 pro-democracy movement has been a critical juncture for a step towards democratic consolidation. However, state coercion may continually be exerted despite institutional specification by law in South Korean context. Explicit case would be amendment of ‘the Law on Assembly and Demonstration’ which determines citizens’ right to take collective action mostly against government actions. This paper investigates amendment process of the law along with social reality since 1987 until 2015 to see how effectively institutionalization has progressed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=democratic%20transition" title="democratic transition">democratic transition</a>, <a href="https://publications.waset.org/abstracts/search?q=historical%20institutionalism" title=" historical institutionalism"> historical institutionalism</a>, <a href="https://publications.waset.org/abstracts/search?q=state%20coercion" title=" state coercion"> state coercion</a>, <a href="https://publications.waset.org/abstracts/search?q=the%20law%20on%20Assembly%20and%20Demonstration" title=" the law on Assembly and Demonstration"> the law on Assembly and Demonstration</a> </p> <a href="https://publications.waset.org/abstracts/84621/state-coercion-and-social-movements-legacy-of-authoritarian-regime" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84621.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">191</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">2542</span> Pesticide Risk: A Study on the Effectiveness of Organic/Biopesticides in Sustainable Agriculture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Berk%20K%C4%B1l%C4%B1%C3%A7">Berk Kılıç</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96mer%20Ayd%C4%B1n"> Ömer Aydın</a>, <a href="https://publications.waset.org/abstracts/search?q=Kerem%20Mestani"> Kerem Mestani</a>, <a href="https://publications.waset.org/abstracts/search?q=Defne%20Uzun"> Defne Uzun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In agriculture and farming, pesticides are frequently used to kill off or fend off any pests (bugs, bacteria, fungi, etc.). However, traditional pesticides have proven to have harmful effects on both the environment and the human body, such as hazards in the endocrine, neurodevelopmental, and reproductive systems. This experiment aims to test the effectiveness of organic/bio-pesticides (environmentally friendly pesticides) compared to traditional pesticides. Black pepper and garlic will be used as biopesticides in this experiment. The results support that organic farming applying organic pesticides operates through non-toxic mechanisms, offering minimal threats to human well-being and the environment. Consequently, consuming organic produce can significantly diminish the dangers associated with pesticide intake. In this study, method is introduced to reduce pesticide-related risks by promoting organic farming techniques within organic/bio-pesticide usage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pesticide" title="pesticide">pesticide</a>, <a href="https://publications.waset.org/abstracts/search?q=garlic" title=" garlic"> garlic</a>, <a href="https://publications.waset.org/abstracts/search?q=black%20pepper" title=" black pepper"> black pepper</a>, <a href="https://publications.waset.org/abstracts/search?q=bio-pesticide" title=" bio-pesticide"> bio-pesticide</a> </p> <a href="https://publications.waset.org/abstracts/179368/pesticide-risk-a-study-on-the-effectiveness-of-organicbiopesticides-in-sustainable-agriculture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/179368.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">68</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">2541</span> Influence of Biochar Application on Growth, Dry Matter Yield and Nutrition of Corn (Zea mays L.)

There is need to increase soil organic carbon in the soil for higher crop productivity and soil sustainability. Recently biochar is considered as sixth element and work as a catalyst for increasing crop yield, soil fertility, soil sustainability and mitigation of climate change. Biochar was generated at the Sansoli Farm of Anand Agricultural University, Gujarat, India by pyrolysis at temperatures (250-400°C) in absence of oxygen using slow chemical process (using two kilns) from corn stover (Zea mays, L), cluster bean stover (Cyamopsis tetragonoloba) and Prosopis julifera wood. There were 16 treatments; 4 organic sources (3 biochar; corn stover biochar (MS), cluster bean stover (CB) & Prosopis julifera wood (PJ) and one farmyard manure-FYM) with two rate of application (5 & 10 metric tons/ha), so there were eight treatments of organic sources. Eight organic sources was applied with the recommended dose of fertilizers (RDF) (80-40-0 kg/ha N-P-K) while remaining eight organic sources were kept without RDF. Application of corn stover biochar @ 10 metric tons/ha along with RDF (RDF+MS) increased dry matter (DM) yield, crude protein (CP) yield, chlorophyll content and plant height (at 30 and 60 days after sowing) than CB and PJ biochar and FYM. Nutrient uptake of P, K, Ca, Mg, S and Cu were significantly increased with the application of RDF + corn stover @ 10 metric tons/ha while uptake of N and Mn were significantly increased in RDF + corn stover @ 5 metric tons/ha. It was found that soil application of corn stover biochar @ 10 metric tons/ha along with the recommended dose of chemical fertilizers (RDF+MS ) exhibited the highest impact in obtaining significantly higher dry matter and crude protein yields and larger removal of nutrients from the soil and it also beneficial for built up nutrients in soil. It also showed significantly higher organic carbon content and cation exchange capacity in sandy loam soil. The lower dose of corn stover biochar @ 5 metric tons/ha (RDF+ MS) was also remained the second highest for increasing dry matter and crude protein yields of forage corn crop which ultimately resulted in larger removals of nutrients from the soil. This study highlights the importance of mixing of biochar along with recommended dose of fertilizers on its synergistic effect on sandy loam soil nutrient retention, organic carbon content and water holding capacity hence, the amendment value of biochar in sandy loam soil. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biochar" title="biochar">biochar</a>, <a href="https://publications.waset.org/abstracts/search?q=corn%20yield" title=" corn yield"> corn yield</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20%20nutrient" title=" plant nutrient"> plant nutrient</a>, <a href="https://publications.waset.org/abstracts/search?q=fertility%20status" title=" fertility status"> fertility status</a> </p> <a href="https://publications.waset.org/abstracts/122460/influence-of-biochar-application-on-growth-dry-matter-yield-and-nutrition-of-corn-zea-mays-l-grown-on-sandy-loam-soils-of-gujarat-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/122460.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">149</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">2540</span> The Influence of Organic Waste on Vegetable Nutritional Components and Healthy Livelihood, Minna, Niger State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Abdulkadir">A.

Niger state has abundant arable land and water resources thus should be one of the highest producers of agricultural crops in the country. However, the major challenge to agricultural sector today is the loss of soil nutrient coupled with high cost of fertilizer. These have continued to increase the use of fertilizer and decomposed solid waste for enhancing agricultural yield, which have varying effects on the soil as well a threat to human livelihood. Consequently, vegetable yield samples from poultry droppings decomposed household waste manure, NPK treatments and control from each replication were subjected to proximate analysis to determine the nutritional and anti-nutritional component as well as heavy metal concentration. Data collected was analyzed using SPSS software and Randomized complete Block Design means were compared. The result shows that the treatments do not devoid the concentrations of any nutritional components while the anti-nutritional analysis proved that NPK had higher oxalate content than control and organic treats. The concentration of lead and cadmium are within safe permissible level while the mercury level exceeded the FAO/WHO maximum permissible limit for the entire treatments depicts the need for urgent intervention to minimize mercury levels in soil and manure in order to mitigate its toxic effect. Thus, eco-agriculture should be widely accepted and promoted by the stakeholders for soil amendment, higher yield, strategies for sustainable environmental protection, food security, poverty eradication, attainment of sustainable development and healthy livelihood. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-nutritional" title="anti-nutritional">anti-nutritional</a>, <a href="https://publications.waset.org/abstracts/search?q=healthy%20livelihood" title=" healthy livelihood"> healthy livelihood</a>, <a href="https://publications.waset.org/abstracts/search?q=nutritional%20waste" title=" nutritional waste"> nutritional waste</a>, <a href="https://publications.waset.org/abstracts/search?q=organic%20waste" title=" organic waste"> organic waste</a> </p> <a href="https://publications.waset.org/abstracts/32315/the-influence-of-organic-waste-on-vegetable-nutritional-components-and-healthy-livelihood-minna-niger-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32315.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">382</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">2539</span> Secondary Compression Behavior of Organic Soils in One-Dimensional Consolidation Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rinku%20Varghese">Rinku Varghese</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Chandrakaran"> S.

Incremental loading tests were conducted on the clay without and with organic matter. The study was conducted with soil having different organic content keeping all other parameters constant. The tests were conducted on clay and artificially prepared organic soil sample at different vertical pressure. The load increment ratio considered for the test is equal to one. Artificial organic soils are used for the test by adding starch to the clay. The percentage of organic content in starch is determined by adding 5% by weight starch into the clay (inorganic soil) sample and corresponding change in organic content of soil was determined. This was expressed as percentage by weight of starch, and it was found that about 95% organic content in the soil sample. Accordingly percentage of organic content fixed and added to the sample for testing to understand the consolidation behaviour clayey soils with organic content. A detailed study of the results obtained from IL test was investigated. The main items investigated were (i) coefficient of consolidation (cv), (ii) coefficient of volume compression (mv), (iii) coefficient of permeability (k). The consolidation parameter obtained from IL test was used for determining the creep strain and creep parameter and also predicting their variation with vertical stress and organic content. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=consolidation" title="consolidation">consolidation</a>, <a href="https://publications.waset.org/abstracts/search?q=secondary%20compression" title=" secondary compression"> secondary compression</a>, <a href="https://publications.waset.org/abstracts/search?q=creep" title=" creep"> creep</a>, <a href="https://publications.waset.org/abstracts/search?q=starch" title=" starch"> starch</a> </p> <a href="https://publications.waset.org/abstracts/54271/secondary-compression-behavior-of-organic-soils-in-one-dimensional-consolidation-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54271.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">281</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">2538</span> Consumer Behavior in Buying Organic Product: A Case Study of Consumer in the Bangkok Metropolits and Vicinity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Piluntana%20Panpluem">Piluntana Panpluem</a>, <a href="https://publications.waset.org/abstracts/search?q=Monticha%20Putsakum"> Monticha Putsakum</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objectives of this study were to investigate 1) consumers’ behaviors in buying organic products; and 2) the relationships between personal factors, cultural factors, social factors, psychological factors and marketing mix factors, and the behavior in buying organic products of consumers in the greater Bangkok metropolitan area. The sample group was 400 consumers at the age of 15 and older, who bought organic agricultural products from green markets and green shops in Bangkok, including its suburbs. The data were collected by using a questionnaire, which were analyzed by descriptive statistics and chi-square test. The results showed that the consumers bought 3 – 4 types of fresh vegetables with a total expenditure of less than 499 Baht each time. They purchased organic products mainly at a supermarket, 2 – 4 times per month, most frequently on Sundays, which took less than 30 minutes of shopping each time. The purpose of the purchase was for self-consuming. Gaining or retaining good health was the reason for the consumption of the products. Additionally, the first considered factor in the organic product selection was the quality. The decisions in purchasing the products were made directly by consumers, who were influenced mainly by advertising media on television. For the relationships among personal, cultural, social, psychological and marketing mix factors, and consumers’ behavior in buying organic products, the results showed the following: 1) personal factors, which were gender, age and educational level, were related to the behavior in terms of “What”, “Why”, and “Where” the consumers bought organic products (p<0.05); 2) cultural factors were related to “Why” the consumers bought organic products (p<0.05); 3) social factors were related to “Where” and “How” the consumers bought organic products (p<0.05); 4) psychological factors were related to “When” the consumers bought organic products (p<0.05). 5) For the marketing mix factors, “Product” was related to “Who participated” in buying, “What” and “Where” the consumers bought organic products (p<0.05), while “Price” was related to “What” and “When” the consumers bought organic products (p<0.05). “Place” was related to “What” and “How” the consumers bought organic products (p<0.05). Furthermore, “Promotion” was related to “What” and “Where” the consumers bought organic products (p<0.05). <p class="card-text"><strong>Keywords:</strong> <a
