The experiment was conducted to study the response of green gram varieties to different levels of phosphorus and potassium. The experiment was laid out in factorial randomized block design (FRBD) with 12 treatments replicated thrice. Three different green gram varieties viz., V1: IPM 02-3, V2: SGC-20 and V3: SGC-16 were used along with four levels of phosphorus and potassium i.e., N1: control, N2: 40 kg ha-1 P2O5 + 40 kg ha-1 K2O, N3: 50 kg ha-1 P2O5 + 50 kg ha-1 K2O and N4: 60 kg ha-1 P2O5 + 60 kg ha-1 K2O. The study showed that different varieties and application of phosphorus and potassium had major influence on crop growth, yield attributes and yield. The variety IPM 02-3, was found to perform better than the other varieties and recorded the highest seed yield at 548.08 kg ha-1. Application of 60 kg ha-1 P2O5 + 60 kg ha-1 K2O resulted in maximum growth attributes such as plant height, branches plant-1, Leaf area index (LAI), crop growth rate (CGR) and yield attributes and seed yield.
