Abstract:
Field investigation was carried out to study the Impact of integrated nutrient management for maximizing productivity and profitability of soybean [(Glycine max (L.) Merrill] at Tirhut College of Agriculture, farm Dholi, Muzaffarpur, Bihar during kharif season 2016. The experiment was laid out in split-plot design having five nutrient levels in main plot and four in weed management practices in subplot with three replications. Application of 50% RDF + 2.5 t FYM/ha + Vermicompost 1.25 t/ha and 50% RDF + 5 t FYM/ha were equally efficient in increasing the No. of pods/plant (23.50), No. of grain/pod (2.52), grain yield/plant (5.15 g), grain yield (16.94 q/ha) and straw yield (28.64 q/ha) and gross returns (` 67880/ha) than other treatment but net returns (` 40225/ha) and benefit-cost ratio (1.60) was obtained maximum with 50% RDF + 5 t FYM/ha which was at par with 50% RDF + 2.5 t FYM/ha + Vermicompost 1.25 t/ha.
