The experiment consisted of 8 treatments comprising of combinations of four nutrient management practices i.e. organic nutrient management [soil treatment with jeevamrit & seed treatment with Rhizobium + PSB, vermicompost (VC) @ 5 t ha-1 & 3 sprays of vermiwash], inorganic nutrient management (recommended NPK), integrated nutrient management (2.5 t ha-1 VC + 50% of recommended NPK) and farmer’s practice (1.25 t ha-1 VC + 25% of recommended NPK) with two conditions i.e. irrigated and rainfed were tested in split plot design with three replications. Results revealed that growth, yield attributes, grain and straw yield of gram were increased with irrigated condition and nutrient management practices. Under irrigated condition, 15.20 per cent higher yield and 10.41 per cent higher net returns per rupee invested were recorded over rainfed condition. Among nutrient management practices, organic nutrient management recorded significantly higher seed yield (1060.1 kg ha -1 ) as compared to other treatments, followed by integrated nutrient management practice. At the same time organic nutrient management recorded highest net returns (₹ 52467 ha-1 ) and 7.10 net returns per rupee invested. Integrated nutrient management was the second best treatments, recorded higher net returns (₹ 32210 ha-1 ) as compared to inorganic and farmers practice. The available nutrient status of soil (NPK) was significantly higher under organic nutrient management as compared to other treatments.EnglishThesis
