A study was conducted to examine the effect of different sources of phosphorus on soil properties, growth, yield, quality and nutrient content in green gram (Vigna radiata L.) in the soil at Department of Agronomy, College of Agriculture, Dapoli during Summer season of 2022 in Randomized Blok Design comprising eight treatments replicated thrice. It was found from the study that the growth parameters, yield contributing characters, seed and Stover yield, quality parameter viz., protein content, nutrient content and uptake had recorded the highest favourable parameters and there was a significant increase in soil organic carbon, available macronutrients (N, P and K), micronutrients (Fe, Mn, Zn and Cu) contents and optimum net return with good B:C ratio, with the application of 80% N and 100% P₂O₅ through DAP (with 20% N through Urea), followed by the application of N (100%) through Urea and P₂O₅ (100%) through SSP. Thus, the effectiveness of P fertilizers with regard to seed yield follow the order: DAP > SSP > RP.
