Twenty rainfed crops of chickpea on farmer’s fields were surveyed to determine the nodulation status of this important legume crop in Lakki Marwat and Karak districts of North West Frontier Province (NWFP). Ten fields (50%) were found with poor nodulation and 4 fields with fair nodulation, which means that about 70 % crop area needs artificial seed inoculation of this crop. Field experiment to evaluate the effect of rhizobial inoculation and nitrogen application on the performance of chickpea was conducted at two different sites in Bannu division of NWFP. It was found that rhizobial inoculation improved nodulation on the root system of the crop at both sites, however, nitrogen application @ 30 kg ha -1 at sowing could not affect the nodulation status of the crop. Inoculation and fertilizer nitrogen @ 30 kg ha-1 individually and in combination significantly increased the grain yield of the crop at both locations. Significantly higher yield was obtained at Marmondi Azim as compared to Titar khel. The inoculated treatment receiving 30 kg N ha-1 produced the highest grain yield at both locations. There was no significant difference in between the nitrogen treated and inoculated plot
