We have to know the competitive capacity of the Bradyrhizobium and Rhizobium strains, which are going to be used in the leguminous seed inoculations. This study consisted of the testing of four strains of Bradyrhizobium lupini and Rhizobium leguminosarum cicer variety, under the action of four antibiotics produced by edaphic actinomycetes. The method applied was the method of rounds imbued with antibiotic. The results achieved proved the general sensibility of these strains to kanamycin, while in the other cases their sensibility ranges from one strain to another.
