| Sumario: | As a second step in Rhizobium meliloti strain selection, field trials were conducted in the central region of Córdoba, Argentina. The main objective was to assess its N-fixation ability under local average climate-soil-plant conditions, compared with other strains from different sources, and to evaluate its response to massive or multiple inoculation methods in order to address competition problems. Medicago sativa L. cv. Polihíbrido Manfredi seeds were planted in a completely randomized block design with 5 repetitions over 2 seasons. Dry matter and N-content (as protein percentage) were determined at 3 cuttings when the crop reached 10% flowering. The results showed an increase in yield and protein content with inoculation, even with a high indigenous population. Under these ecological conditions, both selected indigenous strains and those recommended by INTA showed similar behavior in terms of N-fixation ability, and no differences were detected in response to inoculation methods (simple or multiple). |
