This study was conducted at the Libyan Biotechnology Research Center to investigate  and evaluate the efficiency of two local isolates of Rhizobium Leguminosarum bacteria in root nodulation and improvement of the growth of faba bean. The two studied isolates were isolated from two geographically different regions in Libya (Qasir Ibn Ghashir and Shahhat). The experiment was designed according to the completely randomized Design (CRD). The experiment included two treatments (isolates) and three replicants of every isolate. The results showed superiority of R2 isolate in all studied growth characteristics (plant height, number of leaves, root length, root fresh weight, and the fresh and dry weight of stems and leaves) when compared to R1 isolate. Treating the plant with R2 isolate increased also the number of active nodules and the total weight of nodules. The results of all examined characteristics indicate that R2 isolate which is isolated from shahhat is significantly better in improving plant growth, which is as a result of the effect on nitrogen fixation and production of some plant hormones.
