A field experiment was conducted at Agronomy farm, College of Agriculture, Bikaner during Rabi, 2009-10. The experiment was laid out in factorial randomized block design with three replications, assigning twelve treatments consisting of four levels of phosphorus (control, 20, 40 and 60 kg ha-1) and three levels of zinc (control, 3.0 and 6.0 kg ha-1). The results indicated that the application of phosphorus up to 40 kg ha-1 significantly increased the plant growth (plant height at 60, 90, at harvest, dry matter accumulation at 60, 90 and 120 DAS and nodules per plant), yield attributes (grain pod-1, pods plant-1), yield (grain, straw and biological yield), net returns (Rs. 21006.58 ha-1), B:C ratio (2.58) whereas, dry matter accumulation at 30 DAS, primary and secondary branches at 60 DAS and at harvest, increasing dose of zinc up to 6 kg ha-1 significantly increased the plant growth (Primary and secondary branches plant-1 at 30 DAS and at harvest, dry matter accumulation at 60, 90 and 120 DAS, chlorophyll content, nodules plant-1), yield attributes (grains pod-1, pods plant-1), yield (grain, straw and biological yield), net returns (Rs. 21810.83 ha-1), B:C ratio (2.62) whereas, phosphorus content in grain and straw decreased with the increasing level of zinc. Dry matter accumulation at 30 DAS and plant height at different stages significantly increased only up to application of zinc 3 kg ha-1. The combined effect of phosphorus x zinc were found significant for nodules per plant, pods per plant, grain yield.
