Low soil fertility is the major production constraints for common bean. A field experiment was conducted at National Agricultural Research Council (NARC), Islamabad, Pakistan during 2016- 2017 to study the impact of blended NPS levels on the yield and yield traits of common bean cultivars. The factors studied were six rates of blended NPS (0, 50, 100, 150, 200 and 250 kg ha-1) that contain 19% N, 38% P2O5 and 7% S and three common bean varieties (Long Red Bean, Nasir, and Local Kashmir). The experiment was laid out in RCB design with split plot arrangements replicated thrice. Results showed that greatest branches and pods plant-1 were recorded with 250 kg NPS ha-1. Sub effect revealed that Long Red Bean gave the highest branches and pods plant-1. Interactions revealed that Long Red Bean exhibited highest No. of days to flowering and physiological maturity with 200 - 250 kg NPS ha-1. Long Red Bean gave maximum biomass and grain yield with 250 kg NPSha-1.It is concluded that Long Red Bean had high yield potential and best suited to agro-climatic conditions of NARC, Pakistan.
