Abstract
A field experiment was conducted to study the effect of integrated nutrient management on growth and yield of spring mungbean (Vigna radiata (L.) Wilczek) cultivars in Bundelkhand region of Uttar Pradesh during season of 2019 at Banda University of Agriculture and Technology, Banda (Uttar Pradesh). The experiment was laid out in asymmetrical factorial randomized block design with 6 treatment combinations of integrated nutrient management practices with 2 varieties. Results revealed that cultivar “Shikha” suits to be the better over “Samrat” in respect of growth, yield attributes, seed yield and economics. Additionally, INM practices had better effect on growth, yield attributes compared to sole application of inorganic fertilizers and vermicompost treatments. 100% RDF + 100% vermicompost had highest seed yield (771kg/ha), closely followed by 75% RDF + 50% vermicompost (741 kg/ha) compared to rest of treatments. Among the INM treatments, application of 50% RDF blended with 50% vermicompost recorded at par values of growth, yield attributes and seed yield over the application of 100% RDF + 100% vermicompost and 75% RDF + 50% vermicompost. On an average, INM treatments noted 69.89, 14.07 and 43.39% higher net returns as well as 68.92, 21.2 and 51.57% more benefit: cost ratio over the control, 100% RDF and 100% vermicompost, respectively. Therefore, application of 50% RDF + 50% vermicompost (1.25 t/ha) was optimum under the existing condition of Bundelkhand.
