Effect of integrated nutrient management on growth and yield of green gram [Vigna radiata (L) Wilczek].

The impact of integrated nutrient management was studied on growth and production, in green gram (Vigna radiata L.). Ten nutrient management treatments including fertilizer levels with or without inorganic fertilizers, Rhizobium, PSB and FYM were used in the present study. The plant height, dry weight per plant, leaf area index, no. of root nodules per plant and number of pods per plant were significantly increased with the use of fertilizers, biofertilizers and FYM application. It also improved yield (grain yield by 164% and straw yield by 121%), and yield attributing factors. The addition of FYM, together with Rhizobium and PSB, assisted in boosting output in comparison to the control. However, 100% RDF + PSB + Rhizobium + FYM (2.5 t ha^-1) significantly improved the gross return (154%), net returns (551%), and benefit-cost ratio (137%). Therefore, higher yield of green gram can be achieved with integrated use of various nutrient sources were achieved usingsuch as inorganic fertilizers (RDF), bio-fertilizers, and FYM).
