Abstract

Afield experiment was carried out at field of College of Agricultural Engineering Sciences, University of Duhok during winter season 2020 -2021 to investigate different bio-fertilizer and promising chickpea genotypes on yield and yield components.
The experiment designed in factorial experiments complete randomize block design with three replications. The results showed that the effected of chickpea genotypes, bio- fertilizer and their interaction between them on the most studied traits. The chickpea FLipo7- 245c was superior in the plant height (65 cm), first pod height (39 cm), number of nodules per plant (29.25), 100 seed weight (44.33 g) comparing with FLipo7-223c genotype. Concerning the bio – fertilizer, the rate 6 kg ha-1 recorded the highest values for all studied traits except number of pods per plant with increasing in yield 33.9% comparing with zero bio-fertilizer. Also the interaction between chickpea genotypes and bio-fertilizer were significant for all traits except number of nodules per plant and 100 seed weight (g). For these results, the chickpea was responded to different rate of bio-fertilizer and its important role in the most yield components. The simple correlation coefficient gave high value between yield and main branches (0.63) and first pod height 0.74 and also this study exhibited that the main branches per plant, number of pods per plant and plant height were the major contributed to seed yield
