Abstract
Alfalfa and soybean are the most important leguminous plants in the agricultural system of the semi-arid region of Argentina. The possible action of phosphorous solubilizing bacteria on the leguminous-rhizobia simbiosis was studied since in this region the available phosphorous distribution (Pd) is not uniform. The strains used were Sinorhizobium meliloti 3DOh13, excellent solubilizer of Fe and P for alfalfa, Bradyrhizobium japonicum TIIIB for soybean and two strains of Pseudomonas putida (Sp21 and Sp22) solubilizers of P for the treatments on growth promotion through an improvement in the nodulation and biological nitrogen fixing activity. The rhizobia strains assayed are capable of coexisting with Pseudomonas, with meaningful differences being observed in percentage of nodulation and air portion in co-inoculated soybean.
