The crop-livestock integration system has proven to be an excellent alternative to maximize productivity in agricultural systems, optimizing the use of natural resources such as water and soil. The goal was to identify viable intercropping of grass with other forage plants, in succession to soybean cultivation. Two trials were carried out in a completely randomized design with five replicates. In the first experiment (1), the treatments consisted of six intercropping with Brachiaria brizantha cv. BRS Paiaguás palisadegrass (grass + forage turnip, grass + pigeon pea cv. BRS mandarim, grass + pigeon pea v. IAPAR 143, grass + C. spectablis, grass + C. ochroleuca and grass + C. juncea), while the second experiment (2) was composed of three intercropping with paiaguás grass (Grass + pigeon pea cv Super N Bonamigo, Grass + Sorghum BRS 716 and the "Sextuplo" intercrop - grass + finger millet + pigeon pea + C. ochroleuca+ Niger + forage turnip). The intercropping with forage turnip, biomass sorghum and “sextuplo” were implanted on March 22, 2017, while the other intercropping, on March 13, 2017, at Embrapa agrossilvipastoril, in Sinop-MT, Brazil. The samples were collected on May 12 of the same year. The analysed variables were dry matter content, fresh mass and forage and paiaguás palisadegrass dry mass. The treatments proved to be viable for use in soybean succession. It was observed that the intercroppingusing sorghum decreasing the dry mass of paiaguas palisadegrass. To increase biomass, the intercrop that stood out to the others was the paiaguas palisadegrass with C. juncea. For soybean cultivation in succession, in the first half of March, the intercropping of paiaguas palisadegrass with Crotalaria juncea allows good production of dry mass, with a good stock of nutrients, while for the second half of March it is recommended the paiaguas palisadegrass intercropped with BRS 716 biomass sorghum.
