Introduction Soybean is a significant export product for several countries, including the United States and Brazil. There are numerous varieties of soybean. Among them, genetically modified type known as INTACTA RR2 PRO™ has been designed to demonstrate resistance glyphosate produce toxins that lethal species caterpillars. Limited information available on use Trichoderma harzianum Bacillus subtilis promote plant growth their impact microbiome. Methods This study aimed evaluate effects these microorganisms this soybean cultivar by analyzing parameters, such root shoot dry matter, nutritional status, soil microbial diversity. Results The results indicated treatments with B. alone or in combination T. seed applications significantly enhanced height biomass compared other control. No differences phosphorus nitrogen concentrations were detected across treatments, although some showed close correlations nutrients. Microbial inoculations slightly influenced microbiomes, beta diversity between environments, but had limited overall community composition. Discussion combined application particularly promoted plant-associated groups, Rhizobiaceae, optimizing plant-microbe interactions. Furthermore, resulted slight reduction fungal richness
