Performance of black gram as influenced by organic and inorganic source of nutrients under rainfed conditions

Abstract

A field experiment was conducted to study the effect of integrated nutrient management on growth, development and yield of blackgram at Kuthulia Research farm, College of Agriculture, Rewa (M.P.) during kharif 2019. The experiment was laid out in randomized block design replicated thrice with nine nutrient management treatments. The results revealed that integration of 50% RDF + 50% RDN through compost + Rhizobium resulted into significantly higher maximum leaf area index (4.42) at 45 DAS, number of pods/plant (32.40), number of seeds/pod (8.50), 1000 seed weight (46.40 g) and seed yield (778 kg/ha) closely followed by 100% RDN through compost (organic). N, P and K content in soil differed significantly due to combination of INM treatments during the year of investigation (Table 2). Among treatments, the highest available nitrogen, phosphorus and potassium in (50% RDF + 50% RDN through compost + Rhizobium) (T9), respectively was noted with the soil test based over control.
