The objective of this research was to evaluate the corn grain yield and dry mass of Brachiaria forage in two intercrop in crop-livestock integration system at winter-spring season in the Brazilian Cerrado. The experiment was carried out during the 2006 growing season, at the Engineering College Experimental Station (FE/UNESP, Ilha Solteira Campus), Selvíria, Mato Grosso do Sul State, Brazil. The experimental design used was in randomized blocks, in factorial scheme (4x2), with five replications. The treatments were four Brachiaria species (Brachiaria brizantha cv. 'Marandu', Brachiaria decumbens, Brachiaria ruziziensis and Brachiaria híbrido cv. 'Mulato II') intercropped on rows and spread on total area during corn sowing. It were evaluated the production components, the grain corn yield and the dry mass yield of Brachiaria forage after the corn harvest. The forages intercropped at spread on total area, with emphasis to Brachiaria ruziziensis, provided lower development of corn plants, lower values of production components and grain yield. Although the dry mass yield was satisfactory (above 2,500kg ha-1), except for Brachiaria brizantha, the other species intercropped at spread on total area were higher, with highlight to Brachiaria decumbens and Brachiaria ruziziensis that showed greater adaptability and forage yield at corn intercrop in crop-livestock integration system.
