Yield, Economics and Energetics of Soybean as Influenced by Integrated Nutrient Management and Genotypes

摘要

Among the yield contributing factors of soybean, nutrient management have been pivotal since the nutrient turnover in soil - plant system is considerably high under intensive cropping, Neither the chemical fertilizer nor the organic/ biological sources alone can achieve production sustainability. Thus, for sustainable soil fertility and productivity of soybean, it becomes imperative to adopt the strategies which are of low cost, eco-friendly, high viable and efficient in managing the crop productionwith no adverse effect on the environment. Therefore, the integrated nutrient management (INM) now -a- days is the only concept which needs to be adopted in agriculture. Similarly, crop genotypes may very in their ability to produce economic yield in a given set of agro -climatic condition. Considering the above facts the present study was under taken.
