In order to evaluation effects of complete micro nutrient … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 5 Oct 2012 · 8,132 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of a Dual-Purpose Chemical Applicator for Paddy FieldsMohammed Shu’aibu Abubakar, Desa Ahmad, Othman Jamarei et al.Problem statement: One of the major problems of rice production is the shortage of labor resulting from migration from rural to urban areas, making it very difficult to meet peak demands for paddy production. In most developing countries of Southeast Asia, agricultural mechanization of paddy field operation is mostly carried out using conventional machines. For example in rice production powerintensive … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,545 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Municipal Solid Waste Compost on the Growth and Production of Vegetable CropsA.E. Ghaly, F.N. AlkoaikProblem statement: MSW has traditionally been dealt with thorough the practice of land filling and incineration. However, deleterious environmental impacts have promoted municipalities in Canada to recycle non-putrescible wastes and compost the putrescible ones. This study aimed at evaluating the effect of MSW compost on the growth and production of three vegetable crops (potatoes, corn and squash). Approach: Each crop … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 8,799 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation the Effects of Biological Fertilizer on Physiological Characteristic and Yield and its Components of Corn (Zea mays L.) Under Drought StressBarmak Jafari Haghighi, Zeynab Yarmahmodi, Omid AlizadehProblem statement: This experiment was carried out for study the effects of chemical and biological fertilizers and interaction between them on some physiological characteristic and yield and its components of seed corn in two different irrigation. Approach: The experiment was conducted in a split plot factorial with completely randomized block design using four replications.

Research ArticleOpen accessIn the abstractEffect of Potassium Levels on Antioxidant Enzymes and Malondialdehyde Content under Drought Stress in Sunflower (Helianthus annuus L.)H. Soleimanzadeh, D. Habibi, M.R. Ardakani et al.Problem Statement: Drought stress as a major adverse factor can lower leaf water potential, leading to reduced turgor and some other responses and ultimately lower crop productivity in arid and semi arid zones. Sunflower is one of the main oil seed crops in Iran, where drought stress is the most limiting factor. Drought stress tolerance requires the activation of complex … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 1 · 31 Mar 2010 · 10,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpatial Variability of Soil Inorganic N in a Mature Oil Palm Plantation in Sabah, MalaysiaAbdul Rahim Anuar, Kah Joh Goh, Tee Bee Heoh, Osumanu Haruna AhmedThe identification and understanding of soil factors influencing yield variability of oil palm enable their efficient management. Soil samples were therefore collected from a fertilizer response trial on oil palm to study the spatial inorganic N distribution and some selected soil chemical properties as affected by long-term N fertilizer applications. The experiment was conducted on mature oil palms grown on … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,689 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Utilization of Peat, Lignite and Industrial Wastes in the Production of Mineral-Organic FertilizersKrystyna Hoffmann, Józef HoffmannThe results of chemical analyses of the composition of peat, lignite, turkey droppings and the potato industry effluent are presented. The results indicate that the substances can be used in mineral-organic fertilizer recipes. Although lignite and peat do not contain assimilable nutrients, from the ecology and pedology point of view they are valuable components of mineral-organic fertilizers. In order to … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,483 accessesView PDFCite
