Response of mungbean (Vigna radiata L.) cultivars to integrated nutrient management in Bundelkhand region of Uttar Pradesh

A field experiment was conducted at Banda University of Agriculture and Technology, Banda (Uttar Pradesh) to study the effect of integrated nutrient management on growth and yield of mungbean (Vigna radiata (L.) Wilczek) cultivars in Bundelkhand region of Uttar Pradesh during kharif season of 2019. The experiment comprised of 12 treatment combinations of integrated nutrient management practices in asymmetrical factorial randomized block design with three replications. Results revealed that cultivar 'IPM 2–3 ’was better over “Virat ”in respect of growth, yield attributes, seed yield and economics. Similarly, INM practices had better effect on growth, yield parameters such as number of pods/plant, number of seeds/pod, seed weight/plant and 1000-seed weight, seed yield and economics as compared to sole application of inorganic fertilizers and vermicompost treatments. However, 100% RDF + 100% vermicompost had highest seed yield (822 kg/ha), closely followed by 75% RDF + 50% vermicompost (791 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 recorded 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, respectively. Therefore, application of 50% RDF + 50% vermicompost (1.25 t/ha) was optimum under the existing condition of Bundelkhand.
