Abstract:
Soybean (Glycine max. L.) has become a miracle crop of the twentieth century. It is a triple beneficiary crop, a valuable feed and an industrial raw material. It is one of the important protein and oil seed crop and occupies third place both in seed and oil production throughout the world. It is also ‘treated as manmade meat’ because of its rich source of protein and fat. Soybean also has medicinal value and helps in prevention as well as treating chronic diseases like heart ailments, osteoporosis, cancer, kidney ailments and menopausal syndromes. The continuous use of NPK fertilizers under intensive cropping system has caused adverse effects on soil properties such as soil structure, density, pH, quantity and quality of organic matter, nutrient cycle within soil profile and biological properties thereby affecting the sustainability of crop production, besides causing environmental pollution (Virmani, 1994) ^[8]. Farmers are facing severe problem on availability of chemical fertilizers for soybean production (Suresh Meena and Ghasolia, 2013) ^[11]. The integrated nutrient management paves the way to overcome these problems, which involves the Methods of sowing and conjunctive use of chemical fertilizers, organic manures and bio-fertilizers to sustain crop production as well as maintenance of soil health. Systematic approach to nutrient management by tapping all possible sources of inorganic in a judicious manner to maintain soil fertility and crop productivity is the essence of integrated nutrient management (INM) (Sangeeta et al., 2014) ^[3]. The present study was planned with hypothesis that among the factors responsible for low productivity in soybean, Sowing Methods and inadequate fertilizer use and emergence of multiple nutrient deficiencies due to poor recycling of organic resources and unbalanced use of fertilizers are important (Chaturvedi et al., 2010) ^[12]. Soybean is an energy rich crop and hence the requirement of major nutrients including secondary and micronutrients is high for soybean (Singh et al., 2006) ^[5]. Keeping above facts in mind the present study was undertaken to study the effect of Integrated approach for maximization of seed yield and Quality in soybean (Glycine max. L.).
