Abstract

Isolation from local soil samples with Phaseolus vulgaris (L.) produced 20 samples from which pure cultures were obtained. A commercial strain of Rhizobium #132 was obtained from Becker Underwood and included as a standard in the experiment. The results demonstrated that a variety of infective and effective of strains of Rhizobium nodulating Phaseolus vulgaris (L.) exist in the native soils of the Rio Grande Valley of Texas. A cluster of effective bacteria was identified and can serve as a basis for recommendations to inoculant industry in the Valley. An isolate collection has been established to serve as a source of material for further research.
