چکیده	Background. The use of biofertilizers can be an eco-friendly method and, in addition to reducing chemical inputs, can be considered a climate-smart agricultural option in semiarid regions. Materials and methods. A field trial was aimed to investigate the effect of biofertilizers (F1: control, F2: Nitroxin, F3: Mesorhizobium, and F4: PhosphoBARVAR) on the growth of chickpea genotypes (G1: ILC-482, G2: ‘Pirouz’, and G3: ‘Jam’) in the Meshginshahr area, Iran. Results. The highest longitudinal growth was recorded with the use of different biofertilizers (F) in G1. The lateral growth and number of secondary branches were higher in G2 + F2 than in the others. The highest aboveground biomass was obtained in G1 + F1 and G1 + F4. Inoculation with Mesorhizobium resulted in the highest number of root nodules in G2 and G3. The application of Mesorhizobium also increased the number of pods. The highest grain yield was obtained in G1+F3 (1.43 t ha–1), and G1 + F2 (1.35 t ha–1). Conclusion. The response of genotypes to bacterial inoculations was different. The weakest growth performance and grain yield production was recorded in G1 without bacterial inoculation. The results showed that the ILC-482 line along with inoculation with Mesorhizobium produced economically acceptable grain yield.
