Green gram (Vigna radiata L.) is one of the most extensively grown pulse crop. It is the basically Kharif season crop but now days it has also good summer season crop. The field investigation was carried out during summer season of 2020 to study the effect of nutrient management of summer green gram (Vigna radiata L.) at RCSM College of Agriculture, Kolhapur (MH),India.The field experiment was laid out in randomized block design with eight treatments of nutrient management and three replications. A spacing of 30 cm between rows and 10cm between plants was adopted in seed sowing.The soil of the experimental field was sandy clay loam in texture, slightly alkaline in reaction (pH 7.43), having electrical conductivity 0.22 dS m-1, bulk density 1.34 mg m-3 and organic carbon content was (0.39%), low in available nitrogen (238.29 kg ha-1), high in available phosphorus (30.61 kg ha-1) and medium in available potassium (251.29 kg ha-1). Phule Vaibhav variety of green gram was used for sowing.The different nutrient management treatments included in the field experimental study were T1-Control (unmanured), T2-100% RDF (20:40:00 NPK kg ha-1),T3-100% RDF + Vermicompost 2.5 t ha-1,T4-100% RDF + Vermicompost 2.5 t ha-1 + Biofertilizer (ST),T5-75% RDF (15:30:00 NPK kg ha-1),T6-75% RDF + Vermicompost 2.5 t ha-1, T7-75% RDF + Vermicompost 2.5 t ha-1 + Biofertilizer (ST), T8- Vermicompost 5 t ha-1+ Biofertilizer (ST). The result reveled that, the yield contributing characters like number of pods plant- 1(21.93), length of pod (8.79 cm), weight of pod plant-1 (14.70 g), number of grains pod-1(11.13), grain yield plant-1 (5.97 g), grain yield (15.70 q ha-1), stover yield (33.97 q ha-1) and biological yield (49.67q ha-1), were more with the integrated application of 100% RDF + Vermicompost 2.5 t ha-1 as well as seed treatment with biofertilizer.The application of 100% RDF + Vermicompost 2.5 t ha-1 + biofertilizer (ST) had significantly maximum gross monetary returns (Rs. 123169.20 ha-1). However, higher net monetary returns (Rs. 71137.97 ha-1) and highest B:C ratio (3.25) recorded under application of 100% RDF (20:40:00 NPK kg ha-1) due to lower cost of chemical fertilizers.
