With the purpose of evaluating the behavior of sorghum and soybean cultivars in intercropping for forage production and sorghum in monoculture, a trial was conducted in the agricultural year of 1996/1997 at the Department of Agriculture of the Universidade Federal de Lavras- MG, on a distrophic red dusky latosol. The experimental design was that of randomized blocks in a 4 x 4 + 4 factorial scheme, with three replications, being made up of four hybrids of forage sorghum (AG-2002, AG-2006, BR-601 and CMSXS-756), four soybean cultivars (CAC-1, Doko RC, UFV-16 and UFV-17) and four additional treatment corresponding to the respective monoculture of sorghum. In the intercropping, a single cutting chose to the soil surface at R5 stage was performed (beginning of the set of the soybean crop seeds), in the sorghum monoculture the cut was done, with grains in mealy stage. The results obtained made it evident that the combination of the cultivar UFV-16 with the hybrids AG-2002 and AG-2006 were the ones which provided the greatest green mass, dry matter and total crude protein yields. Both in the consortium and monoculture, the hybrid AG-2002 was that which stood out the most for dry matter and green mass production. In general, the consortium system provided, in relation to monocultivation, the highest green mass,dry matter and total crude protein yields.
