An present field experiment was carried out to assess the effect of nutrient management on summer green gram (Vigna radiata L.) during summer 2020 at Agronomy Research Farm, RCSM College of Agriculture, Kolhapur (MH), India. The soil of experimental field was sandy clay loam textural class, slightly alkaline in reaction (pH 7.43), having electrical conductivity 0.22 dS m-1, bulk density 1.34 mg m-3 and low organic carbon content (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). The field experiment was laid out in Randomized Block Design (RBD) having eight treatments and three replications. A 30 cm x10cm spacing and Phule Vaibhav variety was used for seed sowing.Total uptake of nutrients were (109.23, 24.63 & 69.92 NPK kg ha-1), respectively by green gram crop and available N, P and K were (259.61, 37.74 & 263.63 NPK kg ha-1), respectively, in soil after harvest were found significantly maximum with the application of 100% RDF + Vermicompost 2.5 t ha-1 as well as seed treatment with biofertilizer. Neutral pH (7.00), lower bulk density (1.30 mg m-3) and highest organic carbon (0.48%) observed under organic treatment such as application of Vermicompost 5 t ha-1 with seed treatment of biofertilizer. However, highest EC (28 dSm-1) recorded under combined application of organic and inorganic sources such as 100% RDF + Vermicompost 5 t ha-1 + biofertilizer (ST).
