Two experiments were conducted: the first was concerned with new growth media for the mass production of Rhizobium strains effective in fixing nitrogen with soybean variety S.J.2., and the second was the evaluation of soybean yield as affected by Rhizobium and fertilizers. From the results of the first experiment, new growth media for the mass production of Rhizobium japonicum strains S-18, UB-138, UB-80, and UB-87 were proposed. The media were obtained by substituting some of the components of the conventional yeast extract mannitol medium with materials such as cane sugar and baker's yeast readily available in the country. Mineral contents required for optimal growth of this strains of organism were also adjusted. The new media appeared to be markedly cheaper than the conventional medium. Results of the second experiment indicated that the highest yield of soybean cultivated in Loie soil series was obtained when the seed was inoculated with a mixed culture of Rhizobium japonicum and phosphorus fertilizer was applied. Direct interaction between the organism and phosphorus fertilizer was also observed
