The number of seeds per plant， number of pods and grain weight of N2R and N3R were higher than those ofcontroland othertreatments;Compared with the control （CK），the yield increased by 6. 15% and 1.32% ，respectively，and the yield of other treatments decreased by 7.47%-16.37% .[Conclusion]In chickpea production，inoculation of rhizobium （especially with 25% nitrogen fertilizer reduction） can achieve stable yield and increase efficiency.
