Competitive behavior of three strains of Rhizobium japonicum was evaluated in a soil free of this organism. The three strains differed in their competitive ability. Strain 110 produced 98% of the nodules when applied in combination with strain 38, and 76% when in combination with strain 76. Strain 76 produced 95% of the nodules when applied in combination with strain 38. Results from treatments inoculated with the individual strains indicated that strain 110 produced the greatest fresh weight and greatest bean yield.
