Abstract: The consortium of cover crops with Bolivian forage sorghum can be interesting for sustainable and profitable agriculture with the forage production for animal feed. In addition, the forage can contribute to increase the productivity of soybeans grown in succession. The objective of this research was to evaluate the influence of the intercropping of Bolivian sorghum and forage on soybean yield. The experimental design was in randomized blocks with 6 treatments and 4 replications. The treatments were the cultivation systems aiming at the following soybean crop: T1: Control (fallow); T2: Single Bolivian sorghum; T3: Bolivian Sorghum + Brachiaria ruziziensis; T4: Bolivian Sorghum + Brachiaria ruziziensis + Pigeon pea; T5: Bolivian Sorghum + Brachiaria ruziziensis + Crotalaria; T6: Brachiaria ruziziensis. Green and dry mass, 100 grains, plant height, stem diameter and biomass productivity were evaluated in Bolivian forage sorghum. The use of Brachiaria ruziziensis is a great option for intercropping with sorghum in the off-season providing soybean productivity in successive cultivation. The fact that forage does not reduce sorghum productivity, this system can be recommended for agricultural renewal, generating economic, agronomic results and benefits.
