Abstract Field experiments were conducted during 2013–2014 at Tashkent, Uzbekistan to evaluate the performance of chickpea variety “Jakhongir” with the variable proportion of nitrogen (N) and bio-fertilizer inoculation in the moderate saline (5.6 ± 0.6 dSm−1) soil condition. The studied treatments were No control (non-fertilized), N1 mineral-N (50 kg N ha−1), N2, mineral-N (75 kg N ha−1), N3, mineral-N (100 kg N ha−1) equivalent 0%, 50%, 75%, and 100% from recommended rate for chickpea, Rhizobium inoculation (Bio) + No control, Rhizobium inoculation (Bio) + N1, Rhizobium inoculation (Bio) + N2, and Rhizobium inoculation (Bio) + N3. Seed inoculation with Rhizobium was significantly superior over no inoculation treatments at all rate of N fertilization. The middle rate of N fertilization 75 kg N ha−1 combined with biofertilizer inoculation had of superior effect on chickpea, producing 73.2% more yield (1.68 Mg ha−1), oil, protein, and sugar content performed 16.4%; 15.0%, and 17.9% higher value, respectively, in comparison to control.
