Integrated nutrient management on economics of green gram (Vigna radiata L.)

An experiment was conducted at Research Farm, Department of Agronomy, Faculty of Agriculture, AKS University, Sherganj, Satna (M.P.) during Kharif season of 2021-22. The experiment consisted of randomize block design three replications. In this experiment, 12 treatment combinations viz., RDF (NPK @ 20: 60: 20 kg/ha) – T₁, 100% nitrogen through FYM – T₂, 100% nitrogen through vermicompost –T₃, 100% nitrogen through poultry manure - T₄, 75% nitrogen through FYM + 25% nitrogen through vermicompost – T₅, 75% nitrogen through vermicompost + 25% nitrogen through poultry manure – T₆, 75% nitrogen through poultry manure + 25% nitrogen through FYM – T₇, 50% nitrogen through FYM + 50% nitrogen through poultry manure – T₈, 50% nitrogen through vermicompost + 50% nitrogen through poultry manure – T₉, 50% nitrogen through FYM + 50% nitrogen through vermicompost – T₁₀, 33% nitrogen through FYM + 33% nitrogen through vermicompost + 33% nitrogen through poultry manure – T₁₁ & 25% nitrogen through FYM + 25% nitrogen through poultry manure + 50% nitrogen through vermicompost – T₁₂. Concluded that application of 100% RDF prove best treatment. Among the INM treatment, application of 100% nitrogen through poultry manure recorded the maximum and significantly higher grain yield (12.19q/ha), gross returns (₹100083.00/ha), net returns (₹79320.00/ ha) and highest B: C ratio of 3.8:1 followed by T₄ than T₃.
