An experiment was conducted during kharif 2019 at University Farm, Banda University of Agriculture and Technology, Banda on silty clay loam. The experiment comprised of 12 treatment combinations of two greengram cultivars viz., ‘IPM 2-3’ and ‘Virat’ and six integrated nutrient management protocols, viz. control, 100% RDF, 100% vermicompost (2.5 t/ha), 100% RDF + 100% VC (2.5 t/ha), 75% RDF + 50% VC (1.25 t/ha) and 50% RDF + 50% VC (1.25 t/ha) were assigned in randomized block design with three replications. The results revealed that both the cultivars of greengram were found comparable with each other, but cultivar ‘IPM 2-3’ found superior in respect of growth, yield attributes, yields and economics over the cultivar ‘Virat’. Further combined effect of organic and inorganic fertilizers established its superiority over the 100% sole application of RDF and vermicompost (2.5 t/ha). Among the INM treatments, application of 50% RDF blended with 50% vermicompost (1.25 t/ha) recorded at par values of growth, yield attributes and yields over the application of 100% RDF + 100% vermicompost (2.5 t/ha) and 75% RDF + 50% vermicompost (1.25 t/ha). On an average, INM treatments recorded 77.2, 12.4 and 30.1% additional gross returns, 169.2, 14.5 and 64.5% higher net returns as well as 43.0, 2.3 and 26.3% more benefit: cost ratio over the control, 100% RDF and 100% vermicompost (2.5 t/ha), respectively. Application of 50% RDF intermingled with 50% vermicompost (1.25 t/ha) recorded statistically at par values of economics, viz. gross and net return to other INM treatments, but this treatment recorded significantly higher values of benefit: cost ratio (2.32) than plot receiving 100% RDF + 100% VC (2.5 t/ha) (2.17) but at par with 75% RDF + 50% VC (1.25 t/ha) (2.30). Thus, it can be concluded that combined application of 50% RDF and 50% vermicompost (1.25 t/ha) was found more productive and economically remunerative particularly for Bundelkhand regions of Uttar Pradesh.
