Abstract: 【Objective】 To understand the effect of rhizobia inoculation on the growth and development of chickpea and the effect of nitrogen fixation under reduced nitrogen fertilizer. 【Methods】 Using Muying1 as the test material, set C₁ (rhizobium A, 1/2 nitrogenfertilizer), C₂ (rhizobium B, 1/2 nitrogenfertilizer), C₃ (rhizobium A. No nitrogen fertilizer), C₄ (rhizobium B, no nitrogen fertilizer), CK₁ (no inoculation, total nitrogen fertilizer), CK₂ (no inoculation, 1/2 nitrogenfertilizer), CK₃ (no inoculation, no nitrogen fertilizer). A total of 7 treatments, measuring the nodule fresh weight, chlorophyll content, dry weight and and its constituent factors of chickpeas in each treatment. 【Results】 The fresh weight of rhizobia inoculated treatment increased significantly, and the dry matter accumulation showed: C₁>C₂> CK₁> CK₂> C₃> C₄> CK₃ in the later biological stage. As the growth period progressed, inoculation with rhizobia increased the chlorophyll content. Main stem pods, seeds per plant, grain weight per plant and yield of chickpea under C₁ and C₂ treatments increased. The yield under the C₁ treatment was 1,928.84 kg/hm², which was 8.83% higher than that of the total nitrogen control; the yield under C₂ treatment was 1,827.59 kg/hm², with an increase of 3.11%. 【Conclusion】 It is possible to achieve stable yield or even increase the yield of chickpea under the condition of reducing nitrogen fertilizer by inoculation of rhizobia, and 1/2 nitrogen fertilizer plus rhizobia A has the best effect.
