A field experiment was conducted to study the individual and combined effect of phosphorus and potassium on morphophysiological traits and yield of chickpea (Cicer arietinum L.) cv. Pusa 417. The observations were recorded on branch number, shoot dry weight, root dry weight and nodule number/plant, nitrogenase activity of nodules, leaf area index, crop growth rate and net assimilation rate. At maturity pod number, 100 seed weight, seed yield and seed yield merit were recorded. A combination of 40 kg P per O per and 20 kg K per O/ha produced maximum yield. The low input of P per O per was compensated by high input of K per O and vice versa. At lower phosphorus levels (0 or 20 kg P per O per/ha) the requirement of potassium was high (40 kg K per O/ha). However, at higher level of phosphorus (40 or 60 kg P per O per/ha) the application of only 20 kg K per O/ha proved effective. Seed yield and seed seed yield merit were enhanced by 82 and 85
