A field experiment was conducted to evaluate the effect of phosphorus (P) levels and Rhizobium inoculation on yield-components and grain yield of (chickpea c.v. NIFA-88) under rainfed conditions at Arid Zone Research Institute, Dera Ismail Khan, during 2003-04. The treatments consisted of P levels; 0, 30, 60 and 90 kg per ha, with and without inoculum. A basal dose of 20 kg per ha, nitrogen was applied just before sowing, at the time of seedbed preparation. The experiment was laid out according to the randomized complete block design, with three replications. The results showed significant variation in number of pods per plant, 1000 seed weight and grain yield, with the application of P and Rhizobium inoculum. The maximum number of pods per plant (25.00) was recorded in the plots receiving 60 kg P2O5 per ha, plus inoculum, but was statistically at par with the pods produced by the treatment of 90 kg P2O5 per ha, plus inoculum (24.67).
