Conteúdo: 	The search for cultivation practices that provide productive, social and environmental benefits to the agroecosystem is of great importance for the sustainable intensification of agriculture. The objective of this study was to determine the effect of multifunctional microorganisms (MM) and mix of cover crops on gas exchange, production components and grain yield of soybean. In the field experiment, conducted by two growing seasons, the experimental design of randomized blocks in factorial scheme 8x2 was used, with four replications. The treatments were composed by the combination of eight vegetal cover and the use or not of MM. The vegetal cover were composed of: 1. Fallow, 2. Corn, 3. Mix 1 (white lupine, buckwheat, white oats, black oats, Crotalaria ochroleuca, C. juncea, turnip, coracana grass, white lupine), 4. Mix 2 (millet, C. ochroleuca, black oats, white oats, buckwheat, coracana grass), 5. Mix 3 (Millet, C. ochroleuca, black oats, white oats, buckwheat, coracana grass), 6. Mix 4 (C. spectabilis, buckwheat, millet and C. breviflora), 7. Mix 5 (oats, buckwheat, millet, piatã grass and C. Ocholeuca); and 8. Mix 6. (black oats, turnip forage, white lupine, coracana grass, buckwheat). The MM consortium used was Serratia marcenses (BRM 32114) + Bacillus sp. (BRM 63573). Soybean plants coinoculated with (BRM 32114) + (BRM 63573) showed an increase in photosynthetic rate (16.65%), stomatal conductance (37.50%), internal CO2 concentration (10%), number of pods per plant (15%), mass of 100 grains (4.04%) and grain yield (14.83%). However, no differences were observed in soybean plants grown in succession to the mix of cover crops, except for the number of grains per pod. Therefore, in this study, the highlight was the consortium of multifunctional microorganisms, technology considered strategic for the sustainable intensification of agriculture.
