Abstract

A field experiment was conducted during kharif seasons of 2010 and 2011  to find out the suitable integrated nutrient management (INM) package for successful blackgram production in eastern part of Uttar Pradesh. The results indicates that significantly higher grain (959 kg ha-1), stover (2479 kg ha-1) and biological (3438 kg ha-1) yields and harvest index (27.9%) of blackgram were recorded with the application of soil test based NPK+10 t FYM ha-1+ Rhizobium + 30kg S ha-1+ 1kg Mo ha-1 over rest of the treatments. With regards to economics, soil test based application of NPK + 10t FYM ha-1 + Rhizobium + 30kg S ha- 1+ 1kg Mo ha-1 resulted in highest gross returns (44,580 ha-1), net returns (26,519 ha-1) and benefit: cost ratio (2.27) over other nutritional treatments. Similarly, integration of FYM, NPKSMo with Rhizobium significantly enhances the nitrogen (3.98% and1.55%), phosphorus (0.53% and 0.27%), potassium (2.52% and 3.53% ), sulphur (0.39% and 0.31%), and molybdenum (4.25 mg kg-1 and 3.59 mg kg-1) contents in grain and stover of blackgram over control, respectively.
