Conteúdo: 	The use of beneficial microorganisms in crop systems can contribute to sustainable agriculture by promoting improvements in crop development and grain yield without damaging the environment. However, there is much uncertainty surrounding the effects of using a combination of microorganisms to promote plant development. The objective of this work was to determine the effects of microorganism species individually and in combination on the biomass production, gas exchange and nutrient contents in the shoots and roots of soybean plants. The experimental design was completely randomized, with 30 treatments and three replicates. The treatments consisted of the application of the rhizobacteria BRM 32109, BRM 32110 and 1301 (Bacillus sp.); BRM 32111 and BRM 32112 (Pseudomonas sp.); BRM 32113 (Burkholderia sp.); BRM 32114 (Serratia sp.); Ab-V5 (Azospirillum brasilense) and 1381 (Azospirillum sp.); the fungus Trichoderma asperellum (a mixture of the isolates UFRA. T06, UFRA. T09, UFRA. T12 and UFRA. T52); 19 combinations of these microorganisms, and a control (no microorganisms). At sowing, the soil was treated with Bradyrhizobium, and then the soybean seeds were inoculated. The microorganism suspension was applied in each treatment at 7 days after planting (DAP) in the soil and at 21 DAP on the seedlings. The Trichoderma pool, Ab-V5, 1301 + 32110, 1301 + 32114, 1301 + Ab-V5 and 32110 + Ab-V5 treatments resulted in significantly higher total biomass accumulation in the soybean plants, with values that were, on average, 25% higher than that in the control treatment. Our results suggest that the use of beneficial microorganisms in cropping systems is a promising technique.
