Research ArticleOpen accessIn the keywordsPotential of Industrial Waste Water Use for Jatropha Cultivation in Arid LandHanaa Hussein Abd El Baky, Mohamed Moursy Hussein, Eman Ahamed IbrahemA pot experiment was conducted in the greenhouse of the National Research Center, Dokki, Cairo, Egypt to investigate the effect of NKP foliar fertilizer and irrigation by Industrial Drainage Water (IDW) on Lipid Peroxidation (LP) and antioxidant enzyme activities [Catalase (CAT), Suproxide Desmatase (SOD) and Ascorbate Peroxidas (APX)] of jatropha plants. Plants fertilized with NPK fertilizers (N0g+P0g+K0g, N3g+P3g+K3g and N6g+P6g+k6g/pot) … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 13 Nov 2013 · 7,472 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Different Exogeneous Compounds on Biosorption of EndosulfanDeepika Dave, A. K. DikshitProblem statement: Organochlorine pesticide endosulfan is widely used as a replacement for DDT and dieldrin in many parts of the world. Presence of residual pesticides in the water, air and soil environment was confirmed since 1960s. Such Persistent Organic Pollutants (POPs) are of concern because of their long-term subtle effects on hormones, the immune system and reproduction. Therefore, it becomes … …American Journal of Environmental Sciences, Vol. 7, Issue 3 · 11 Jul 2011 · 7,202 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSeeking an Alternative Modality to the Management of Nigeria's Fertilizer Subsidy Scheme-An Empirical Approach to the Case Study of Ondo State (1976-1996)Victor O. Asekunowo, Grace T. Olutunla, Adebiyi G. DaramolaProblem statement: The objective of Nigeria’s fertilizer subsidy scheme was to make inorganic fertilizers readily available to farmers at affordable prices in order to boost food production in the country. Shortly into the scheme, farmers complained that fertilizers were not received at the time of need and in sufficient quantities. Approach: Using Ondo State, Nigeria as a case study, to … …Journal of Social Sciences, Vol. 6, Issue 3 · 30 Sep 2010 · 7,831 accessesView PDFCite
Research ArticleOpen accessIn the keywordsReduction of Ammonia Loss by Mixing Urea with Liquid Humic and Fulvic Acids Isolated from Tropical Peat SoilSusilawati Kasim, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid et al.Problem statement: Fertilizer N use efficiency is reduced by ammonia volatilization. Under low soil CEC and high pH, N from soil solution is released to the atmosphere. Ammonia loss due to low worldwide N use efficiency (33%) has been implicated in global warming. Thus, the objectives of this laboratory study were to evaluate the effectiveness of liquid humic and fulvic … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 9,513 accessesView PDFCite

Research ArticleOpen accessIn the keywordsThe Effect of Differentiated Nitrogen Fertilization using Satellite Navigation Systems on the Spring Wheat (Triticum aestivum L.) Crop Yield in the Conditions of Chernozem-Like Soils in the Northern Forest Steppe of the Tyumen Region of RussiaAltynay Oxukbayeva, Nikolai Abramov, Marden Baidalin, Sergei SemizorovSoil cultivation without layers turnover impeded the process of nitrate nitrogen accumulation compared with plowing. The traditional scheme of mineral fertilization applying the averaged standard did not create a heterogeneous level of nutrient supply in primary soil cultivation systems. These factors set them in unequal conditions by default in terms of nitrogen supply to crops. Solid mineral fertilization with the … …OnLine Journal of Biological Sciences, Vol. 23, Issue 1 · 16 Jan 2023 · 5,201 accessesView PDFCite
