Abstract

Soybean has great economic and social importance for Brazil, and nitrogen, the most required nutrient by plants, is fully supplied by bacteria symbiosis. In order to guarantee the biological process maximization, it is necessary to inoculate strains of efficient and competitive bacteria, that accompany the technological development of new cultivars. In Brazil, 50 million doses of inoculants were marketed in the 2016/2017 harvest. This work intends to determine the establishment, in the soil, of microbial populations (Bradyrhizobium japonicum - strain SEMIA 5079, B. diazoefficiens - SEMIA 5080, B. diazoefficiens - USDA 110, Rhizobium tropici - strain CIAT 889; Azospirillum brasilense Ab-V5 and Ab-V6 strains; and Bacillus subtilis - strain QST 713), which in the future have potential for new commercial co-inoculation packages for the crop. Studies about competition, antagonisms, and synergisms with the native microbiota in Brazilian soils are necessary in order to evaluate of bacteria establishment co-inoculated. Sequencing of the DNA region encoding the 16S rRNA gene, carries enough information for phylogenetic analysis and microbial community assembly of N-fixing microorganisms and growth promoters.
