The production systems have been modified due to greater sustainability. The intercropped corn crops with Urochloa ruziziensis provide biomass that can be used as straw in sequential crops, favoring the intensification of productive areas. Investigating and proposing a phytotechnical arrangement between corn and brachiaria is important to favor the production of forage / grain, and consequently animal production, by minimizing the negative effects of forage shading and maximizing grain productivity. This study was conducted in Colinas do Tocantins, Brazil. The experimental design was in complete randomized blocks in a factorial scheme (2x2x2). The treatments consisted of three factors: 1- corn seeding spacing (0.45m and 0.90m); 2- planting orientation (north-south and east-west); 3- forage planting method (corn planting line and in between corn planting line). Corn grain yield, forage dry matter yield and grass height were evaluated on the day of the corn harvest. The yield of corn grains and dry mass of forage, does not depend on the spacing and orientation of the planting of corn. The height of the grass at the time of the corn harvest shows significant differences.
