Maize flour of different sieve mesh sizes of 1.00mm, 1.9 mm, 1.4 mm, 1.68 mm and 2.0 mm was used to produce Kokoro. The samples were analysed for protein, fat, moisture content, crude fibre, ash and sensory evaluation. The various mixture obtained were separately processed into snacks following essential traditional method of production. The result of the sensory evaluation showed that Kokoro of sample 546 using 1.0mm mesh sieve size was the most preferred and sample 513 using 2.00 was least preferred. The result revealed that the more the maize was well blended the more acceptable the product is to the consumer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=particle%20sizes" title="particle sizes">particle sizes</a>, <a href="https://publications.waset.org/abstracts/search?q=maize%20flour" title=" maize flour"> maize flour</a>, <a href="https://publications.waset.org/abstracts/search?q=quality" title=" quality"> quality</a>, <a href="https://publications.waset.org/abstracts/search?q=Kokoro" title=" Kokoro"> Kokoro</a> </p> <a href="https://publications.waset.org/abstracts/79646/effects-of-particle-sizes-of-maize-flour-on-the-quality-of-traditional-maize-snack-kokoro" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79646.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">272</span> Role of Selenite and Selenate Uptake by Maize Plants in Chlorophyll A and B Content</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Garousi">F.

The present study, 2x3 factorial arrangements in completely randomized design was conducted to investigate the effect of maize stover components (whole and upper stover; cut above 5th node). Urea treatment at levels 0, 3, and 6% DM on dry matter digestibility and fermentation kinetics of maize stover using in vitro gas production. After 21 days of urea treatment, results illustrated that there was no interaction between maize stover components and urea treatment on 48h in vitro dry matter digestibility (IVDMD). IVDMD was unaffected by maize stover components (P > 0.05), average IVDMD was 55%. However, using whole maize stover gave higher cumulative gas and gas kinetic parameters than those of upper stover (P<0.05). Treating maize stover by ensiling with urea resulted in a significant linear increase in IVDMD (P<0.05). IVDMD increased from 42.6% to 53.9% when increased urea concentration from 0 to 3% and maximum IVDMD (65.1%) was observed when maize stover was ensiled with 6% urea. Maize stover treated with urea at levels of 0, 3, and 6% linearly increased cumulative gas production at 96h (31.1 vs 50.5 and 59.1 ml, respectively) and all gas kinetic parameters excepted the gas production from the immediately soluble fraction (P<0.50). The results indicate that maize stover treated with 6% urea enhance in vitro dry matter digestibility and fermentation kinetics. This study provides a practical approach to increasing utilization of maize stover in feeding ruminant animals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maize%20stover" title="maize stover">maize stover</a>, <a href="https://publications.waset.org/abstracts/search?q=urea%20treatment" title=" urea treatment"> urea treatment</a>, <a href="https://publications.waset.org/abstracts/search?q=ruminant%20feed" title=" ruminant feed"> ruminant feed</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20production" title=" gas production"> gas production</a> </p> <a href="https://publications.waset.org/abstracts/73526/investigation-of-influence-of-maize-stover-components-and-urea-treatment-on-dry-matter-digestibility-and-fermentation-kinetics-using-in-vitro-gas-techniques" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/73526.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">224</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">270</span> Brevicoryne brassicae Compatibility with Maize in Multiple Cropping System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zunnu%20Raen%20Akhtar">Zunnu Raen Akhtar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Brevicoryne brassicae, aphid feeds on cabbage and Brassica sp. as preferred host. Brassica plants usually ripen when maize starts growing in multiple cropping systems. Experiment was conducted to observe suitability of B. brassicae by rearing it on maize as host. In a tritrophic eco-system, predator coccinellids can be found in the fields of brassica and maize. This experiment emphasized on issue of aphids growing incidence in a cropping system. Brassica is sown and harvested earlier than maize and is attacked by aphids, while maize is also attacked by aphids. Five mortality tests were conducted of B. brassicae fed on maize. Out of five mortality tests, 3 tests were conducted using 1st instar, while in two mortality tests, 2nd instars of aphids were used. Mortality tests revealed that first instar mortality was quite high on the second day, while in second instar larvae mortality was delayed up to third to the fourth day. These experiments reveal that aphids can use maize as substitute host at later instars as compared to young ones. These experiments can be foundation for studying further crop-insect interaction and sampling techniques used for this purpose. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=host%20suitability" title="host suitability">host suitability</a>, <a href="https://publications.waset.org/abstracts/search?q=B.%20brassicae" title=" B. brassicae"> B. brassicae</a>, <a href="https://publications.waset.org/abstracts/search?q=maize" title=" maize"> maize</a>, <a href="https://publications.waset.org/abstracts/search?q=tritrophic%20interaction" title=" tritrophic interaction"> tritrophic interaction</a> </p> <a href="https://publications.waset.org/abstracts/74393/brevicoryne-brassicae-compatibility-with-maize-in-multiple-cropping-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74393.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">194</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">269</span> Identification of a Novel Maize Dehydration-Responsive Gene with a Potential Role in Improving Maize Drought Tolerance</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyle%20Phillips">Kyle Phillips</a>, <a href="https://publications.waset.org/abstracts/search?q=Ndiko%20Ludidi"> Ndiko Ludidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Global climate change has resulted in altered rainfall patterns, which has resulted in annual losses in maize crop yields due to drought. Therefore it is important to produce maize cultivars that are more drought-tolerant, which is not an easily accomplished task as plants have a plethora of physical and biochemical adaptation methods. One such mechanism is the drought-induced expression of enzymatic and non-enzymatic proteins which assist plants to resist the effects of drought on their growth and development. One of these proteins is AtRD22 which has been identified in Arabidopsis thaliana. Using an in silico approach, a maize protein with 48% sequence homology to AtRD22 has been identified. This protein appears to be localized in the extracellular matrix, similarly to AtRD22. Promoter analysis of the encoding gene reveals cis-acting elements suggestive of induction of the gene’s expression by abscisic acid (ABA). Semi-quantitative transcriptomic analysis of the putative maize RD22 has revealed an increase in transcript levels after the exposure to drought. Current work elucidates the effect of up-regulation and silencing of the maize RD22 gene on the tolerance of maize to drought. The potential role of the maize RD22 gene in maize drought tolerance can be used as a tool to improve food security. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abscisic%20acid" title="abscisic acid">abscisic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=drought-responsive%20cis-acting%20elements" title=" drought-responsive cis-acting elements"> drought-responsive cis-acting elements</a>, <a href="https://publications.waset.org/abstracts/search?q=maize%20drought%20tolerance" title=" maize drought tolerance"> maize drought tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=RD22" title=" RD22"> RD22</a> </p> <a href="https://publications.waset.org/abstracts/24320/identification-of-a-novel-maize-dehydration-responsive-gene-with-a-potential-role-in-improving-maize-drought-tolerance" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24320.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">464</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">268</span> Modelling Public Knowledge and Attitude towards Genetically Modified Maize in Kenya</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ezrah%20Kipkirui%20Tonui">Ezrah Kipkirui Tonui</a>, <a href="https://publications.waset.org/abstracts/search?q=George%20Otieno%20Orwa"> George Otieno Orwa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A survey of 138 farmers was conducted in Rift valley, Kenya, in November and December 2013 in three counties (Uasin-gishu, Elgeyo-marakwet, and Tranzoia) to determine public knowledge and attitude towards genetically modified (GM) maize. Above two third (70%) of the respondents had knowledge of GM maize, mostly those educated and male. Female was found to be having low knowledge on GM maize. Public acknowledged the technology’s potential positive impacts, with more than 90% willing to adopt and more than 98% willing to buy GM seedlings at any given price. A small percentage less than 3% were of a negative opinion about willing to buy and adopt GM seeds. We conclude that GM technology has a role to play in food security in Kenya. However, the public needs more information about the technology, which can be provided through established sources of information and training. Finally, public knowledge and attitude on GM maize should be studied on a regular basis, and the survey population broadened to 47 counties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=public" title="public">public</a>, <a href="https://publications.waset.org/abstracts/search?q=knowledge" title=" knowledge"> knowledge</a>, <a href="https://publications.waset.org/abstracts/search?q=attitudes" title=" attitudes"> attitudes</a>, <a href="https://publications.waset.org/abstracts/search?q=GM%20maize" title=" GM maize"> GM maize</a>, <a href="https://publications.waset.org/abstracts/search?q=Kenya" title=" Kenya"> Kenya</a> </p> <a href="https://publications.waset.org/abstracts/8651/modelling-public-knowledge-and-attitude-towards-genetically-modified-maize-in-kenya" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/8651.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">267</span> Effect of Selenite and Selenate Uptake by Maize Plants on Specific Leaf Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20Garousi">F.

Traditional maize sheller needs to be carried from place to place by hooking with two-wheel tractor (2WT) and set up again for shelling operation which takes longer time for preparation of maize shelling. The mobile maize sheller eliminates the transportation problem and can start shelling operation instantly any place as it is attached together with 2WT. It is counterclockwise rotating cylinder, axial flow type sheller, and grain separated with a frictional force between spike tooth and concave. The maize sheller is attached with nuts and bolts in front of the engine base of 2WT. The operating power of the sheller comes from the fly wheel of the engine of the tractor through ‘V” belt pulley arrangement. The average shelling capacity of the mobile sheller is 2.0 t/hr, broken kernel 2.2%, and shelling efficiency 97%. The average maize shelling cost is Tk. 0.22/kg and traditional custom hire rate is Tk.1.0/kg, respectively (1 US$=Tk.78.0). The service provider of the 2WT can transport the mobile maize sheller long distance in operator’s seating position. The manufacturers started the fabrication of mobile maize sheller.

A hydroponic experiment was conducted to investigate the role of exogenous application of silicon under cadmium stress in six different maize hybrids with five treatments comprising of control, 7.5 µM Cd + 5 mM Si, 7.5 µM Cd + 10 mM Si, 15 µM Cd + 5 mM Si and 15 µM Cd + 10 mM Si. Results revealed that treatments of plants with 10mM Si application under both 7.5µM Cd and 15 µM Cd stress resulted in maximum improvement in plant morphological attributes (root and shoot length, root and shoot fresh and dry weight, leaf area and relative water contents) and antioxidant enzymes (POD and CAT) relative to 5 mM Si application in all maize hybrids. Results regarding Cd concentrations showed that Cd was more retained in roots followed by shoots and then leaves and maximum reduction in Cd uptake was observed at 10mM Si application. Maize hybrid 6525 showed maximum growth and least concentration of Cd whereas maize hybrid 1543 showed the minimum growth and maximum Cd concentration among all maize hybrids. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title="antioxidant">antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=cadmium" title=" cadmium"> cadmium</a>, <a href="https://publications.waset.org/abstracts/search?q=maize" title=" maize"> maize</a>, <a href="https://publications.waset.org/abstracts/search?q=silicon" title=" silicon"> silicon</a> </p> <a href="https://publications.waset.org/abstracts/35284/effect-of-silicon-in-mitigating-cadmium-toxicity-in-maize" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35284.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">518</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">261</span> Nutritional Composition of Provitamin A-Biofortified Amahewu, a Maize Based Beverage with Potential to Alleviate Vitamin A Deficiency </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Temitope%20%20D.%20%20Awobusuyi">Temitope D.

It is traditionally made with white maize which is deficient in vitamin A. Provitamin A-biofortified maize has been developed for use as a complementary strategy to alleviate vitamin A deficiency. In this study the nutritional composition and protein digestibility of amahewu produced using provitamin A-biofortified maize was determined. Provitamin A-biofortified amahewu was processed by fermenting cooked maize porridge using malted provitamin A-biofortified maize, wheat bran and lactobacillus mixed starter culture with either malted maize or wheat bran. The total provitamin A content in amahewu products ranged from 3.3-3.8 μg/g (DW). The % retention of total provitamin A ranged from 79 %- 90 % μg/g (DW). The lowest % retention was observed in products fermented with the addition of starter culture. The gross energy of amahewu products were approx. 20 MJ/kg. There was a slight increase in the lysine content of amahewu after fermentation. Protein digestibility of amahewu (approx.91%) was slightly higher compared to unprocessed provitamin A maize (86%). However, a general decrease was observed in the minerals when compared to the unprocessed provitamin A maize. Amahewu processed using starter cultures has higher iron content than those processed with the addition of malt. These result suggests that provitamin A-biofortified amahewu has the potential to make a significant contribution towards alleviating Vitamin A Deficiency in rural communities who are also the most vulnerable to VAD. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=vitamin%20A%20deficiency" title="vitamin A deficiency">vitamin A deficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=provitamin%20A%20maize" title=" provitamin A maize"> provitamin A maize</a>, <a href="https://publications.waset.org/abstracts/search?q=biofortification" title=" biofortification"> biofortification</a>, <a href="https://publications.waset.org/abstracts/search?q=fermentation" title=" fermentation "> fermentation </a> </p> <a href="https://publications.waset.org/abstracts/42204/nutritional-composition-of-provitamin-a-biofortified-amahewu-a-maize-based-beverage-with-potential-to-alleviate-vitamin-a-deficiency" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42204.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">417</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">260</span> Effect of Tillage Practices and Planting Patterns on Growth and Yield of Maize (Zee Maize)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=O.%20R.%20Obalowu">O.

In order to maximize output, there is need to recommend a suitable tillage practice for crop production which will increase the growth and yield of maize. This study investigated the effect of tillage practices and planting pattern on the growth and yield of maize. The experiment was arranged in a 4x3x3 Randomized Complete Block Design (RCBD) layout, with four tillage practices consisting of no-tillage (NT), disc ploughing only (Ponly), disc ploughing followed by harrowing (PH), and disc ploughing, harrowing then ridging (PHR). Three planting patterns which include; 65 x 75, 75 x 75 and 85 x 75 cm spacing within and between the rows respectively, were randomly applied on the plots. All treatments were replicated three times. Data which consist of plant height, stem girth, leaf area and weight of maize per plots were taken and recorded. Data gathered were analyzed using Analysis of Variance (ANOVA) in the Minitab Software Package. The result shows that PHR under the third planting pattern has the highest growth rate (216.50 cm) while NT under the first planting pattern has the lowest mean value of growth rate (115.60 cm). Also, Ponly under the first planting pattern gives a better maize yield (19.45 kg) when compared with other tillage practices while NT under first planting pattern recorded the least yield of maize (9.40 kg). In conclusion, considering soil and weather conditions of the research area, plough only under the first planting pattern (65 x 75 cm) is the best alternative for the production of the Swan maize variety. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=tillage%20practice" title="tillage practice">tillage practice</a>, <a href="https://publications.waset.org/abstracts/search?q=planting%20pattern" title=" planting pattern"> planting pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=disc%20ploughing" title=" disc ploughing"> disc ploughing</a>, <a href="https://publications.waset.org/abstracts/search?q=harrowing" title=" harrowing"> harrowing</a>, <a href="https://publications.waset.org/abstracts/search?q=ridging" title=" ridging"> ridging</a> </p> <a href="https://publications.waset.org/abstracts/35634/effect-of-tillage-practices-and-planting-patterns-on-growth-and-yield-of-maize-zee-maize" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35634.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">491</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">259</span> The Impact of Three Different Insecticides Against Fall Armyworms on Maize Productivity, in Somalia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ali%20Hassan">Ahmed Ali Hassan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The fall armyworm (FAW) was first identified in 2016 in Africa. FAW is widely distributed in Somalia and severely damages the maize crop. The effect of three different pesticides used to control the autumn armyworm, Spodoptera frugiperda (Noctuidae: Lepidoptera), on maize productivity was investigated in this study. During the 2020–2021 growing season, three insecticides (Malathion 57 EC, Ampligo150 ZC, and Carbryle 85 WP) were evaluated at field demonstration plots. Our result showed that significant mortality of S. frugiperda was observed on the treatment plot treated with Amplico. After spraying, Ampligo resulted in (92.200%) larval death. Compared to Carbaryl, which was less active and only caused 36.367% mortality after application, Malathion had a moderate mortality rate of 53.733%. Consequently, our current finding shows that the three selected insecticides reduced the damage and infestation level of S. frugiperda in the maize field conditions, and the most effective treatment was Amplico. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=maize" title="maize">maize</a>, <a href="https://publications.waset.org/abstracts/search?q=fall%20armyworm" title=" fall armyworm"> fall armyworm</a>, <a href="https://publications.waset.org/abstracts/search?q=insecticides" title=" insecticides"> insecticides</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a> </p> <a href="https://publications.waset.org/abstracts/191889/the-impact-of-three-different-insecticides-against-fall-armyworms-on-maize-productivity-in-somalia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191889.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">25</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">258</span> Understanding the Impact of Climate-Induced Rural-Urban Migration on the Technical Efficiency of Maize Production in Malawi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Innocent%20Pangapanga-Phiri">Innocent Pangapanga-Phiri</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Dada%20Mungatana"> Eric Dada Mungatana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study estimates the effect of climate-induced rural-urban migrants (RUM) on maize productivity.

In maize processing, one of its post-harvest operations that is still facing a major challenge is dehusking. Therefore, a maize dehusking machine that could replace the prevalent traditional method of dehusking maize in developing countries, especially Nigeria was designed, constructed and tested at the Department of Agricultural and Bio-Environmental Engineering Technology, Rufus Giwa Polytechnic, Owo. The basic features of the machine are feeding unit (hopper), housing frame, dehusking unit, drive mechanism and discharge outlets. The machine was tested with maize of 50mm average diameter at 13% moisture content and 2.5mm machine roller clearance. Test results showed appreciable performance with the dehusking efficiency of 92% and throughput capacity of 200 Kg/hr at a machine speed of 400rpm. The estimated production cost of the machine at the time of construction is forty-five thousand, one hundred and eighty nairas (₦45,180) excluding the cost of the electric motor. It is therefore recommended for small and medium-scale maize farmers and processors in Nigeria. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=construction" title="construction">construction</a>, <a href="https://publications.waset.org/abstracts/search?q=dehusking" title=" dehusking"> dehusking</a>, <a href="https://publications.waset.org/abstracts/search?q=design" title=" design"> design</a>, <a href="https://publications.waset.org/abstracts/search?q=efficiency" title=" efficiency"> efficiency</a>, <a href="https://publications.waset.org/abstracts/search?q=maize" title=" maize"> maize</a> </p> <a href="https://publications.waset.org/abstracts/84517/design-and-construction-of-a-maize-dehusking-machine-for-small-and-medium-scale-farmers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84517.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">323</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">256</span> Laboratory Scale Purification of Water from Copper Waste</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mumtaz%20Khan">Mumtaz Khan</a>, <a href="https://publications.waset.org/abstracts/search?q=Adeel%20Shahid"> Adeel Shahid</a>, <a href="https://publications.waset.org/abstracts/search?q=Waqas%20Khan"> Waqas Khan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heavy metals presence in water streams is a big danger for aquatic life and ultimately effects human health. Removal of copper (Cu) by ispaghula husk, maize fibre, and maize oil cake from synthetic solution in batch conditions was studied. Different experimental parameters such as contact time, initial solution pH, agitation rate, initial Cu concentration, biosorbent concentration, and biosorbent particle size has been studied to quantify the Cu biosorption. The rate of adsorption of metal ions was very fast at the beginning and became slow after reaching the saturation point, followed by a slower active metabolic uptake of metal ions into the cells. Up to a certain point, (pH=4, concentration of Cu = ~ 640 mg/l, agitation rate = ~ 400 rpm, biosorbent concentration = ~ 0.5g, 3g, 3g for ispaghula husk, maize fiber and maize oil cake, respectively) increasing the pH, concentration of Cu, agitation rate, and biosorbent concentration, increased the biosorption rate; however the sorption capacity increased by decreasing the particle size. At optimized experimental parameters, the maximum Cu biosorption by ispaghula husk, maize fibre and maize oil cake were 86.7%, 59.6% and 71.3%, respectively. Moreover, the results of the kinetics studies demonstrated that the biosorption of copper on ispaghula husk, maize fibre, and maize oil cake followed pseudo-second order kinetics. The results of adsorption were fitted to both the Langmuir and Freundlich models. The Langmuir model represented the sorption process better than Freundlich, and R² value ~ 0.978. Optimizations of physical and environmental parameters revealed, ispaghula husk as more potent copper biosorbent than maize fibre, and maize oil cake. The sorbent is cheap and available easily, so this study can be applied to remove Cu impurities on pilot and industrial scale after certain modifications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biosorption" title="biosorption">biosorption</a>, <a href="https://publications.waset.org/abstracts/search?q=copper" title=" copper"> copper</a>, <a href="https://publications.waset.org/abstracts/search?q=ispaghula%20husk" title=" ispaghula husk"> ispaghula husk</a>, <a href="https://publications.waset.org/abstracts/search?q=maize%20fibre" title=" maize fibre"> maize fibre</a>, <a href="https://publications.waset.org/abstracts/search?q=maize%20oil%20cake" title=" maize oil cake"> maize oil cake</a>, <a href="https://publications.waset.org/abstracts/search?q=purification" title=" purification"> purification</a> </p> <a href="https://publications.waset.org/abstracts/78915/laboratory-scale-purification-of-water-from-copper-waste" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78915.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">410</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">255</span> Integration of Agroforestry Shrub for Diversification and Improved Smallholder Production: A Case of Cajanus cajan-Zea Mays (Pigeonpea-Maize) Production in Ghana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20O.%20Danquah">F.

The study was conducted in the Forest zones of Ghana during the major and minor seasons of 2023 cropping seasons to evaluate maize yield productivity improvement and profitability of integrating Cajanus cajan (pigeonpea) into a maize production system described as a pigeonpea-maize cropping system. This is towards an integrated soil fertility management (ISFM) with a legume shrub pigeonpea for sustainable maize production while improving smallholder farmers' resilience to climate change. A split-plot design with maize-pigeonpea (Pigeonpea-Maize intercrop – MPP and No pigeonpea/ Sole maize – NPP) and inorganic fertilizer rate (250 kg/ha of 15-15-15 N-P2O5-K2O + 250 kg/ha Sulphate of Ammonia (SoA) – Full rate (FR), 125 kg/ha of 15-15-15 N-P2O5-K2O + 125 kg/ha Sulphate of Ammonia (SoA) – Half rate (HR) and no inorganic fertilizer (NF) as control) was used as the main plot and subplot treatments respectively. The results indicated a significant interaction of the pigeonpea-maize cropping system and inorganic fertilizer rate on the growth and yield of the maize with better and similar maize productivity when HR and FR were used with pigeonpea biomass. Thus, the integration of pigeonpea and its biomass would result in the reduction of recommended fertiliser rate to half. This would improve farmers’ income and profitability for sustainable maize production in the face of climate change. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agroforestry%20tree" title="agroforestry tree">agroforestry tree</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20soil%20fertility%20management" title=" integrated soil fertility management"> integrated soil fertility management</a>, <a href="https://publications.waset.org/abstracts/search?q=resource%20use%20efficiency" title=" resource use efficiency"> resource use efficiency</a> </p> <a href="https://publications.waset.org/abstracts/182972/integration-of-agroforestry-shrub-for-diversification-and-improved-smallholder-production-a-case-of-cajanus-cajan-zea-mays-pigeonpea-maize-production-in-ghana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182972.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">57</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">254</span> Evaluation of the Most Effective Insecticides against the Spodoptera Frugiperda, on the Maize Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Ali%20Hassan">Ahmed Ali Hassan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In 2016, the Fall Armyworm (FAW) was first discovered in Africa. FAW is abundantly present in Somalia and seriously harms the maize crop. This investigation examined the impact on maize productivity of three different pesticides used to combat the autumn armyworm, Spodoptera frugiperda (Noctuidae: Lepidoptera). During the 2020–2021 growing season, three insecticides (Malathion 57 EC, Ampligo150 ZC, and Carbryle 85 WP) were evaluated at field demonstration plots. Our result showed that, significant mortality of S. frugiperda was observed on the treatment plot treated with Amplico. Ampligo caused over 90% larval mortality after application. Malathion had moderate activity, causing 53.733% mortality after application, while Carbaryl was less effective, causing 36.367% mortality after application. Consequently, the current finding shows that the three selected insecticides reduced the damage and infestation level of S. frugiperda in the maize field conditions and the most effective treatment were Amplico. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pesticides" title="pesticides">pesticides</a>, <a href="https://publications.waset.org/abstracts/search?q=maize%20fall%20army%20worm" title=" maize fall army worm"> maize fall army worm</a>, <a href="https://publications.waset.org/abstracts/search?q=insecticides" title=" insecticides"> insecticides</a>, <a href="https://publications.waset.org/abstracts/search?q=mortality" title=" mortality"> mortality</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20frugiperda" title=" S. frugiperda"> S. frugiperda</a> </p> <a href="https://publications.waset.org/abstracts/169800/evaluation-of-the-most-effective-insecticides-against-the-spodoptera-frugiperda-on-the-maize-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/169800.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">70</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">253</span> Prediction of Metals Available to Maize Seedlings in Crude Oil Contaminated Soil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stella%20O.%20Olubodun">Stella O.

Three methods were used to determine the bioavailability of metals in the soils: maize (<em>Zea mays</em>) plant, EDTA and BCR sequential extraction. The sequential extract acid soluble fraction of the BCR extraction (most labile fraction of the soils, normally associated with bioavailability) were compared with total metal concentration in maize seedlings as a means to compare the chemical and biological measures of bioavailability. Total Fe was higher in comparison to other metals for the crude oil contaminated soils. The metal concentrations were below the limits of 4.7% Fe, 190mg/kg Cu and 720mg/kg Zn intervention values and 36mg/kg Cu and 140mg/kg Zn target values for soils provided by the Department of Petroleum Resources (DPR) guidelines. The concentration of the metals in maize seedlings increased with increasing rates of crude oil contamination. Comparison of the metal concentrations in maize seedlings with EDTA extractable concentrations showed that EDTA extracted more metals than maize plant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=availability" title="availability">availability</a>, <a href="https://publications.waset.org/abstracts/search?q=crude%20oil%20contamination" title=" crude oil contamination"> crude oil contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=EDTA" title=" EDTA"> EDTA</a>, <a href="https://publications.waset.org/abstracts/search?q=maize" title=" maize"> maize</a>, <a href="https://publications.waset.org/abstracts/search?q=metals" title=" metals"> metals</a> </p> <a href="https://publications.waset.org/abstracts/38382/prediction-of-metals-available-to-maize-seedlings-in-crude-oil-contaminated-soil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38382.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">227</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">252</span> Gendered Perceptions in Maize Supply Chains: Evidence from Uganda</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anusha%20De">Anusha De</a>, <a href="https://publications.waset.org/abstracts/search?q=Bjorn%20Van%20Campenhout"> Bjorn Van Campenhout</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Faced with imperfect information, economic actors use judgment and perceptions in decision-making. Inaccurate perceptions or false beliefs may result in inefficient value chains, and systematic bias in perceptions may affect inclusiveness. In this paper, perceptions in Ugandan maize supply chains are studied. A random sample of maize farmers where they were asked to rate other value chain actors—agro-input dealers, assembly traders and maize millers—on a set of important attributes such as service quality, price competitiveness, ease of access, and overall reputation. These other value chain actors are tracked and asked to assess themselves on the same attributes. It is observed that input dealers, traders and millers assess themselves more favorably than farmers do. Zooming in on heterogeneity in perceptions related to gender, it is evident that women rate higher than men. The sex of the actor being rated does not affect the rating. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gender" title="gender">gender</a>, <a href="https://publications.waset.org/abstracts/search?q=input%20dealers" title=" input dealers"> input dealers</a>, <a href="https://publications.waset.org/abstracts/search?q=maize%20supply%20chain" title=" maize supply chain"> maize supply chain</a>, <a href="https://publications.waset.org/abstracts/search?q=perceptions" title=" perceptions"> perceptions</a>, <a href="https://publications.waset.org/abstracts/search?q=processors" title=" processors"> processors</a> </p> <a href="https://publications.waset.org/abstracts/137754/gendered-perceptions-in-maize-supply-chains-evidence-from-uganda" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/137754.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">166</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">251</span> Effect of Tillage Technology on Species Composition of Weeds in Monoculture of Maize</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Svetlana%20Chovancova">Svetlana Chovancova</a>, <a href="https://publications.waset.org/abstracts/search?q=Frantisek%20Illek"> Frantisek Illek</a>, <a href="https://publications.waset.org/abstracts/search?q=Jan%20Winkler"> Jan Winkler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of tillage technology of maize on intensity of weed infestation and weed species composition was observed at experimental field.

Variants of tillage technology are CT: plowing – conventional tillage 0.22 m, MT: loosening – disc tillage on the depth of 0.1 – 0.12 m, NT: direct sowing – without tillage. The evaluation of weed infestation was carried out by numerical method in years 2012 and 2013. Within the monitoring were found 20 various species of weeds. Conventional tillage (CT) primarily supports the occurrence of perennial weeds (Cirsium arvense, Convolvulus arvensis). Late spring species (Chenopodium album, Echinochloa crus-galli) were more frequently noticed on variants of loosening (MT) and direct sowing (NT).

To this end, the study sought to identify the factors influencing adoption intensity of certified maize varieties. The data used were obtained from a sample household survey of 406 maize farmers, conducted in the northern guinea savannah of Nigeria through multistage stratified sampling, structured questionnaire. A triple hurdle model was adopted to estimate the determinants of adoption intensity; considering awareness, adoption, and intensity as three separate stages. The result showed that the drivers of farmers’ awareness, adoption, and intensity of usage may not necessarily be the same, and where they are, not of the same magnitude and direction. However, factors which were found to be statistically significant were age, education, membership of association and frequency of extension advice. In addition, awareness and adoption of the technologies were likely to be increased with male respondents. Farmers that were members of either community organizations or cooperative organizations had a higher tendency of being aware and adopting certified maize seed varieties. It was also discovered that though some of the farmers were fully aware of the existence of some certified maize varieties, majority lacked detailed knowledge and technical know-how. There is a need for creation of awareness through an excellent trained extension and restructuring of the educational sector to improve on the adoption process as well as improve maize productivity in the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adoption" title="adoption">adoption</a>, <a href="https://publications.waset.org/abstracts/search?q=awareness" title=" awareness"> awareness</a>, <a href="https://publications.waset.org/abstracts/search?q=maize%20farmers" title=" maize farmers"> maize farmers</a>, <a href="https://publications.waset.org/abstracts/search?q=Nigeria" title=" Nigeria"> Nigeria</a>, <a href="https://publications.waset.org/abstracts/search?q=regression" title=" regression"> regression</a> </p> <a href="https://publications.waset.org/abstracts/83281/drivers-of-adoption-intensity-of-certified-maize-varieties-in-northern-guinea-savannah-of-nigeria-a-triple-hurdle-model-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83281.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">174</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">249</span> Mapping QTLs Associated with Salinity Tolerance in Maize at Seedling Stage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Muhebbullah%20Ibne%20Hoque">Mohammad Muhebbullah Ibne Hoque</a>, <a href="https://publications.waset.org/abstracts/search?q=Zheng%20Jun"> Zheng Jun</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang%20Guoying"> Wang Guoying</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Salinity stress is one of the most important abiotic factors contributing to crop growth and yield loss. Exploring the genetic basis is necessary to develop maize varieties with salinity tolerance. In order to discover the inherent basis for salinity tolerance traits in maize, 121 polymorphic SSR markers were used to analyze 163 F2 individuals derived from a single cross of inbred line B73 (a salt susceptible inbred line) and CZ-7 (a salt tolerant inbred line). A linkage map was constructed and the map covered 1195.2 cM of maize genome with an average distance of 9.88 cM between marker loci. Ten salt tolerance traits at seedling stage were evaluated for QTL analysis in maize seedlings. A total of 41 QTLs associated with seedling shoot and root traits were detected, with 16 and 25 QTLs under non-salinity and salinity condition, respectively. And only 4 major stable QTLs were detected in two environments. The detected QTLs were distributed on chromosomes 1, 2, 4, 5, 6, 7, 8, 9, and chromosome 10. Phenotypic variability for the identified QTLs for all the traits was in the range from 6.27 to 21.97%. Fourteen QTLs with more than 10% contributions were observed. Our results and the markers associated with the major QTL detected in this study have the potential application for genetic improvement of salt tolerance in maize through marker-assisted selection. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=salt%20tolerance" title="salt tolerance">salt tolerance</a>, <a href="https://publications.waset.org/abstracts/search?q=seedling%20stage" title=" seedling stage"> seedling stage</a>, <a href="https://publications.waset.org/abstracts/search?q=root%20shoot%20traits" title=" root shoot traits"> root shoot traits</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20trait%20loci" title=" quantitative trait loci"> quantitative trait loci</a>, <a href="https://publications.waset.org/abstracts/search?q=simple%20sequence%20repeat" title=" simple sequence repeat"> simple sequence repeat</a>, <a href="https://publications.waset.org/abstracts/search?q=maize" title=" maize"> maize</a> </p> <a href="https://publications.waset.org/abstracts/14120/mapping-qtls-associated-with-salinity-tolerance-in-maize-at-seedling-stage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14120.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">320</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">248</span> Effects of Molybdenum Treatments on Maize and Sunflower Seedlings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Eva%20Bodi">Eva Bodi</a>, <a href="https://publications.waset.org/abstracts/search?q=Szilvia%20Veres"> Szilvia Veres</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzaneh%20Garousi"> Farzaneh Garousi</a>, <a href="https://publications.waset.org/abstracts/search?q=Szilvia%20Varallay"> Szilvia Varallay</a>, <a href="https://publications.waset.org/abstracts/search?q=Bela%20Kovacs"> Bela Kovacs</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the present study was to examine whether increasing molybdenum (Mo) concentration affects on the growth and Mo concentration of maize and sunflower (Helianthus annuus L. cv Arena PR) seedlings within laboratory conditions. In this experiment calcareous chernozem soil was used and Mo was supplemented into the soil as ammonium molybdate [(NH4)6Mo7O24.4H2O] in four different concentrations as follow: 0 (control), 30, 90 and 270 mg/kg. In this study we found that molybdenum in small amount (30 mg/kg) affects positively on growth of maize and sunflower seedlings, however, higher concentration of Mo reduces the dry weights of shoots and roots. In the case of maize the highest Mo treatment (270 mg/kg) and in sunflower 90 mg/kg treatment caused significant reduction in plant growth. In addition, we observed that molybdenum contents in the roots and shoots were very low in case of control soil but were significantly elevated with increasing concentration of Mo treatment. Only in case of sunflower the highest 270 mg/kg Mo treatment caused decrease in Mo concentration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dry%20weight" title="dry weight">dry weight</a>, <a href="https://publications.waset.org/abstracts/search?q=maize" title=" maize"> maize</a>, <a href="https://publications.waset.org/abstracts/search?q=molybdenum" title=" molybdenum"> molybdenum</a>, <a href="https://publications.waset.org/abstracts/search?q=sunflower" title=" sunflower"> sunflower</a> </p> <a href="https://publications.waset.org/abstracts/21245/effects-of-molybdenum-treatments-on-maize-and-sunflower-seedlings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21245.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">247</span> Women Entrepreneurial Skills in Maize Processing and Value Addition in Ogun State, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wasiu%20Oyeleke%20Oyediran">Wasiu Oyeleke Oyediran</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Maize is a common staple food for human consumption and livestock feeds. It provides employment and means of livelihood for women in both rural areas and urban centres in Nigeria. However, the entrepreneurial skills of women engaged in its processing and value addition has not been fully enhanced. This study was therefore carried out to investigate rural women entrepreneurial skills in maize processing and value addition in Ogun State, Nigeria. Snow ball sampling technique was used in the selection of 70 respondents for this study. Data were analyzed with descriptive statistics and chi-square. Results revealed that majority (50.0%) of the respondents were 31 - 40 years of age and 60% of the respondents had spent 6 – 10 years in maize processing. The respondents have great entrepreneurial skills in popcorn (85.7%), corn cake (80.0%), corn balls (64.3%) and kokoro (52.9%) making. The majority of the respondents accessed information and entrepreneurial skills through fellow processors (88.6%) and friends and neighbours (62.9%). Major constraints to maize processing and value addition were scarcity of raw materials during off season periods (95.7%), ineffective preservation methods (88.6%), lack of modern processing equipment (82.9%), and high cost of processing machines (72.9%). Result of chi-square showed that there is significant association between personal characteristics of the respondents and entrepreneurial skills of the women at p < 0.05. It is hereby recommended that subsidized processing equipment should be made available to the maize processors in the study area by the government and NGOs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=women" title="women">women</a>, <a href="https://publications.waset.org/abstracts/search?q=entreprenuerial%20skills" title=" entreprenuerial skills"> entreprenuerial skills</a>, <a href="https://publications.waset.org/abstracts/search?q=maize%20prcessing" title=" maize prcessing"> maize prcessing</a>, <a href="https://publications.waset.org/abstracts/search?q=value%20addition" title=" value addition"> value addition</a> </p> <a href="https://publications.waset.org/abstracts/77023/women-entrepreneurial-skills-in-maize-processing-and-value-addition-in-ogun-state-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77023.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">220</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">246</span> Mapping the Land Use Changes in Cultivation Areas of Maize and Soybean from 2006 to 2017 in North West and Free State Provinces, South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Ngcinela">S.

Several factors contribute to this trend, for example, the ever-increasing human population, the need to produce more food than before, and the expansion of industrial and agricultural areas. This paper, focused on the cultivation patterns, land use change over time, of maize and soybean (i.e. both genetically modified and non-genetically modified) in two South African provinces to establish their land cover changes over time. From a global context, genetically modified crops have been advocated by some to be saving land – due to more yield over small cultivation area(s); while other argue and even criticise their cultivation as they take up more land, replace other crops or are the expense of natural (pristine) vegetation. The study quantified and mapped land used for the cultivation of maize and soybean from 2006 to 2017 in Free State and North West provinces, using ArcGIS. The results show both provinces to have minimal expansion or change in cultivation area for both maize and soybean between 2006 and 2017. The results further indicate that both maize and soybean cultivation areas in these provinces, did not expand beyond the current agricultural areas (space), and did not encroach onto new land areas. This suggests that both maize and soybean, do not currently pose a threat to the surrounding landscape and are not in direct coemption with other neighboring land use practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=agriculture" title="agriculture">agriculture</a>, <a href="https://publications.waset.org/abstracts/search?q=crops" title=" crops"> crops</a>, <a href="https://publications.waset.org/abstracts/search?q=cultivation" title=" cultivation"> cultivation</a>, <a href="https://publications.waset.org/abstracts/search?q=genetically%20modified" title=" genetically modified"> genetically modified</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use" title=" land use"> land use</a>, <a href="https://publications.waset.org/abstracts/search?q=maize" title=" maize"> maize</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean" title=" soybean"> soybean</a> </p> <a href="https://publications.waset.org/abstracts/158126/mapping-the-land-use-changes-in-cultivation-areas-of-maize-and-soybean-from-2006-to-2017-in-north-west-and-free-state-provinces-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/158126.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">167</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">245</span> Characterization of Common Maize Ear Rot Pathogens in Ilesa Nigeria and Their Potential Control Using Selected Arbuscular Mycorrhizal Fungi</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olumayowa%20M.%20Olowe">Olumayowa M.

This study, therefore, aims at characterizing and controlling Fusarium strains using arbuscular mycorrhizal fungi. Maize ear showing rot symptoms were obtained from some selected farms located at Ilesa East and West using random sampling technique. Isolation of Fusarium pathogen from infected maize grain was done using direct pour plate method on potato dextrose agar (PDA) and was characterized based on morphological and molecular ITS-amplification methods. The reaction of PVASYN8F2, T2LCOMP1STR SYN-W-1, and T2LCOMP4 maize varieties, to the Fusarium ear rot pathogens and biocontrol efficacy of the mycorrhizal fungi were assessed on growth, yield, agronomic parameters and symptoms observed. The strains; olowILH1 and olowILH2 identified as Fusarium napiforme were the most dominant and virulent pathogens associated with the maize. They showed genetic similarity with documented ear rot pathogens on NCBI with accession numbers Fusarium proliferatum KT224027, KT224023, and Fusarium sp AY237110. They both exhibited varying inhibitory effects on the three maize varieties compare to control (uninfected plant) which had better growth characteristics. It was also observed that strain olowILH1 was more virulent than olowILH2. T2LCOMP4 was generally more susceptible to both fungal strains compared to the other two maize (T2LCOMP1STR SYN-W-1 and T2LCOMP4 ). In all, strain olowILH1 was more virulent than olowILH2, and Glomus clarum had higher inhibitory pathogenic effect against Fusarium strains compared to G. deserticola. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arbuscular%20mycorrhizal%20fungi" title="arbuscular mycorrhizal fungi">arbuscular mycorrhizal fungi</a>, <a href="https://publications.waset.org/abstracts/search?q=disease%20management" title=" disease management"> disease management</a>, <a href="https://publications.waset.org/abstracts/search?q=Fusarium%20strains" title=" Fusarium strains"> Fusarium strains</a>, <a href="https://publications.waset.org/abstracts/search?q=identification" title=" identification"> identification</a> </p> <a href="https://publications.waset.org/abstracts/106889/characterization-of-common-maize-ear-rot-pathogens-in-ilesa-nigeria-and-their-potential-control-using-selected-arbuscular-mycorrhizal-fungi" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106889.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">173</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">244</span> Effect of Different Phosphorus Levels on Vegetative Growth of Maize Variety</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tegene%20Nigussie">Tegene Nigussie</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Maize is the most domesticated of all the field crops. Wild maize has not been found to date and there has been much speculation on its origin. Regardless of the validity of different theories, it is generally agreed that the center of origin of maize is Central America, primarily Mexico and the Caribbean. Maize in Africa is of a recent introduction although data suggest that it was present in Nigeria even before Columbus voyages. After being taken to Europe in 1493, maize was introduced to Africa and distributed (spread through the continent by different routes. Maize is an important cereal crop in Ethiopia in general, it is the primarily stable food, and rural households show strong preference. For human food, the important constituents of grain are carbohydrates (starch and sugars), protein, fat or oil (in the embryo) and minerals. About 75 percent of the kernel is starch, a range of 60.80 percent but low protein content (8-15%). In Ethiopia, the introduction of modern farming techniques appears to be a priority. However, the adoption of modern inputs by peasant farmers is found to be very slow, for example, the adoption rate of fertilizer, an input that is relatively adopted, is very slow. The difference in socio-economic factors lay behind the low rate of technological adoption, including price & marketing input. Objective: The aim of the study is to determine the optimum application rate or level of different phosphorus fertilizers for the vegetative growth of maize and to identify the effect of different phosphorus rates on the growth and development of maize. Methods: The vegetative parameter (above ground) measurement from five plants randomly sampled from the middle rows of each plot. Results: The interaction of nitrogen and maize variety showed a significant at (p<0.01) effect on plant height, with the application of 60kg/ha and BH140 maize variety in combination and root length with the application of 60kg/ha of nitrogen and BH140 variety of maize. The highest mean (12.33) of the number of leaves per plant and mean (7.1) of the number of nodes per plant can be used as an alternative for better vegetative growth of maize. Conclusion and Recommendation: Maize is one of the popular and cultivated crops in Ethiopia. This study was conducted to investigate the best dosage of phosphorus for vegetative growth, yield, and better quality of maize variety and to recommend a level of phosphorus rate and the best variety adaptable to the specific soil condition or area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=leaf" title="leaf">leaf</a>, <a
