The paper presents the study of nutrient sources influence on the growth of Bradyrhizobium japonicum and Azospirillum brasilense at their co-cultivation. It was shown that at cultivation of diazotrophs in nutrient media with different concentrations of its components, soybean rhizobia had uneven growth activity. Glucose and molasses was observed to have the greatest impact on the rhizobia count. The results obtained are used as the basis for the optimization of culture medium for co-cultivation of rhizobia and azospirills.
