Abstract: Plant growth and germination can be affected by a number of factors, the most important of which is water stress. The aim of our work is to study the effect of amendment by chickpea flour on the germination of seeds of the Douyet variety and to monitor plant growth under water deficit. After germination of the seeds of the Douyet variety, the plants were separated into two batches and then placed in pots under glass. Different amendments (2, 5 and 10% of chickpea flour) were applied to the plants. Water deficit was applied with irrigation at 40% and 80% of field capacity (FC). The parameters analyzed were the final percentage of seed germination (FPG), and the Germination energy (GE). The final germination percentage of the Douyet variety was FGP 90% and the germination energy of the seeds was GE 58%. The results showed also that plants amended with a concentration of 10% chickpea flour showed an improvement over control plants in the physiological parameters analyzed, in particular chlorophyll (65%), total soluble sugars (33%) and proline levels compared with plants in the control group. The growth of plants amended with chickpea flour powder increased significantly compared with control plants. At 10% amendment, growth increased by 26.7% underwater deficit conditions. In conclusion, treatment with chickpea flour improved the growth of chickpea plants underwater deficit.

Abstract: Natural process of fixing molecular nitrogen to ammonium is called biological nitrogen fixation. By supplying nitrogen to legume plants, it helps to support sustainable agriculture globally. The most significant leguminous crop, faba beans, can coexist symbiotically with soil bacteria called rhizobia. The purpose of this study was to isolate, describe, and assess Rhizobium nodulating faba bean's symbiotic efficacy. YEMA-CR was used to isolate a total of 24 Rhizobium isolates. Every isolate was described using YEMA based on how they responded to phenotypic traits. Every isolate tested positive for BTB, catalase, and indole and was found to be motile, gram-negative, rod-shaped, and incapable of absorbing Congo red. The pattern of intrinsic antibiotic resistance revealed that whereas the majority of isolates were sensitive to tetracycline, the majority were tolerant to ampicillin and pencillin. Every isolate exhibited nodulation in sand culture. All examined metrics showed significant (p<0.05) improvements in plants, according to analyses of variance. Sixty-six percent of isolates were deemed highly successful based on symbiotic effectiveness. According to the results, the study region included Rhizobia bacteria that might be utilized as bio-fertilizer. Therefore, in order to better classify Rhizobium isolates and develop them for inoculants, more research on their field conditions and molecular characterization is required.
