[Inoculation of chickpeas with Rhizobium sp. native to the province of Córdoba, Argentina].

Native strains of Rhizobium were selected from a chickpea growing area with the purpose of producing inoculants tolerant to environmental conditions of the province of Córdoba. The strains were selected for nitrogen fixing capacity and specificity with four plant genotypes using the following parameters: number of nodules, plant biomass and nitrogen content. Native population of Rhizobium spp in the province of Córdoba showed better competition ability than foreign strains with similar response to different plant genotypes.
