Abstract:

A field experiment entitledIntegrated Nutrient Management on Summer Mung bean (Vigna radiata) under Malwa Region was conducted during summer season2021and2022at the field of Agronomy, SAGE University, Indore. There were nine treatment combinations of integrated nutrient management i.e. T1: Control, T2: RDF (20 kg N + 40 kg P2O5/ha), T3: RDF + Rhizobium + PSB, T4: FYM (10 Kg/Ha), T5: FYM + Rh + PSB, T6: RDF (50%) + FYM (2.5 t/ha) + (Rh+ PSB), T7: RDF (50%) + FYM (5 t/ha) + (Rh+ PSB), T8: RDF (25%) + FYM (5 t/ha) + (Rh+ PSB) and T9: RDF (75%) + FYM (5 t/ha) + (Rh+ PSB) with four replications under Randomized Block Design. Based on two years experimental finding on mungbean under the influence of integrated nutrient management during the both seasons i.e., 2021 and 2022 with pooled, it appeared that conjoint application of T9 treatment combination RDF (75%) + FYM (5t/ha) + (Rh + PSB) resulted in significantly superior in plant height, plant dry matter accumulation (gram per meter row length), number of branches (plant-1), chlorophyll content in leaves (mg/g fresh weight of leaves), total number of root nodules (plant-1), effective number of root nodules (plant-1), fresh weight of root nodules (plant-1), and dry weight of root nodules (plant-1), various yield and yield attributing characteristics viz., number of pods (plant -1), number of seeds (Pod -1), test weight (1000 seed weight in grams), seed yield (Kg ha -1), straw yield (Kg ha -1), biological yield (Kg ha -1), harvest index (%), protein content (%) in seed, protein yield (Kg ha -1) by seed, nutrient content, nutrient uptake, cost of cultivation (Rs. ha-1), gross return (Rs. ha-1), net return (Rs. ha-1) and B:C ratio.
