Research ArticleOpen accessIn the abstractIMPROVING PHOSPHORUS NUTRITION OF CORNWalter B. Gordon, Larry Murphy, Pawel WiatrakPhosphorus (P) generally occurs in soils as the anions H2PO4- or HPO4-2 depending on soil pH. These anions readily react with soil cations such as calcium, magnesium, iron and aluminum to produce various phosphate compounds of very limited water solubility. Crop recovery of applied phosphate fertilizer can be quite low during the season of application. In addition, the large amounts … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 18 Mar 2014 · 7,446 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT OF POLYETHYLENE BLACK PLASTIC MULCH ON GROWTH AND YIELD OF TWO SUMMER VEGETABLE CROPS UNDER RAIN-FED CONDITIONS UNDER SEMI-ARID REGION CONDITIONSAtif Y. MahadeenWater use efficiency in agriculture can be enhanced by several strategies mainly by reducing evaporation from the soil surface. The mulching techniques were being used widely in irrigated crop production worldwide. The mulching techniques can be also implemented in summer vegetables production under rain-fed conditions. The current study aimed at evaluating the effect of polyethylene black plastic mulch on growth … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 29 Jan 2014 · 9,007 accessesView PDFCite
Research ArticleOpen accessIn the abstractDisposal of Agro-Industrials Wastes as Soil AmendmentsAli Mekki, Fatma Arous, Fathi Aloui, Sami SayadiWe investigated the fertilizing potential of three agro-industrial wastes (Compost (C), Dehydrated Manures (DM) and Digestate (D)) on soil properties, on seeds germination and the plants growth. Results showed that the addition of wastes modified several soil properties as pH, Electrical Conductivity (EC), Water Retention Capacity (WRC) and Soil Organic Matter (SOM). Hence, SOM increase from 1.5% in unamended soil … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 11 Jan 2014 · 7,014 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT OF UREA WITH NUTRISPHERE-N POLYMER IN FALL AND SPRING NITROGEN APPLICATIONS FOR CORNPawel Wiatrak, Walter B. GordonPolymer coated urea may be a viable option to improve Nitrogen (N) uptake and corn (Zea mays L.) grain yields, especially in areas with relatively high soil N loss. The objective of this study was to evaluate the effect of two urea application timings (fall and spring) and three N rates (90, 180 and 270 kg N ha-1) with and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 27 Dec 2013 · 8,150 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential 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 abstractPotential Environment and Public Health Risk Due to Contamination of Heavy Metals from Industrial Waste Water in Lam Thao, Phu Tho, VietnamNguyen Cong Vinh, Ingrid Oborn, Pham Quang Ha et al.Problem statement: In Vietnam, rice cultivation plays an important role in national economic development and food security. However, rice production is facing many problems associated with rapid industrialization and urbanization in the country. Resultant emissions of solid and liquid wastes are often untreated and discharged directly to agricultural land. These practices have potential impacts on the environment and human health. … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 28 Feb 2012 · 8,427 accessesView PDFCite
Research ArticleOpen accessIn the abstractAgricultural Resources Allocation and Field Crops CompetitionElgilany Ahmed, Jamalludin Sulaiman, Saidatulakmal MohdProblem statement: Field crops are considered as essential cash and food crops produced in River Nile State (RNS) of North Sudan include cereal, food-legumes, vegetables and fodders beside the perennial crops. They are the main source of household income and regarded as a major part of the daily diet for the Sudanese. In other words they play an important role … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 7,979 accessesView PDFCite
Research ArticleOpen accessIn the abstractWheat Production and EconomicsElgilany Ahmed, Jamalludin Sulaiman, Saidatulakmal MohdProblem statement: The crop in the irrigated scheme has faced by manifold problems contributed to low level of productivity and high cost of production of wheat. The crop is commonly produced under pump irrigation from the River Nile. In River Nile State (RNS), wheat is grown under the irrigated sector, the State is considered as a suitable environment for producing … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 3 · 4 Aug 2011 · 10,569 accessesView PDFCite
