The indiscriminate use of chemical fertilizers, its process of production and its application had increased the costs of agricultural production and the environmental problems because of the pollution of air, soil and water sources. The alternative is the use of biological fertilizers as an economical and clean tool in order to sustainable management of ecosystems. However, in the escalation processes of a biofertilizer the costs of production could increase due to the type of formulation and the culture media used for the multiplication of the bacteria. This research, by using statistical designs sequentially, presents the standardization of an economical culture media used to multiply the strain C50 ofRhizobium sp. From eight nutritional sources, five were selected taking as criteria the low economical costs and the availability of above mentioned nutritional sources; from these five sources, three of them influenced the development of the strain significantly. The optimized composition of the alternative culture media included glycerol, molasses, glutamate, yeast extract and salts. There were no significantly differences in the growth of the strain C50 in the alternative culture media compared with the traditional one (yeast extract – mannitol); nor in viability of the strain growth on traditional media culture compared with the alternative one, when it was inoculated on peat. The inoculants conserved its quality in refrigeration during 30 days. The strains J01, T14 and C2 showed a better rate of growth on the alternative culture media; it was not show significant differences in the counts between the strains J01 and T14; whereas, the strain C2 growth better in the alternative culture media.
