Abstract The pots experiment carried out under greenhouse conditions at College of Agriculture of Al-Muthana University during 2013. to investigate the interaction effects of using two foreign strains of bacteria R.leguminosarun were obtained from International Centre for Agriculture Research in the Dry Land (ICARD), and three methods for application the inoculant (carrier, infusion seeds, soil inoculation), by using plastic pots of 5 kg capacity research amid to evaluate the effect of inoculation broad bean plants. A strains diagnosed by biochemical testes, microscopically and morphological characteristics. The parameters recording at two stages (65 and 105) day the number of nodule and dry matter weight of shoot, dry matter weight of roots, plant height recorded. The treatments means compared by using L.S.D. and three replications for each treatment and the completely randomized design (CRD). The results obtained from experiments the biochemical test proved that the two strains belong to the genus Rhizobium the inoculated plants had higher measurements in all examined plant parameters than the uninoculated ones. The interaction effects of inoculant (R483+ Carrier) showed the highest influence on increasing all characters.
