The effect of corn (Zea mays L.) on the growth of Brachiaria brizantha cv. Toledo, as well as the feasibility of intercropping these two crops, was studied in an experiment using a completely randomized block design with five replications and four distances between corn furrows. Treatments of monoculture of the two crops also were studied. With the corn crop the variables yield and number of ears harvested were analyzed. For the forage crop, the botanical composition and the aerial biomass were determined. In addition, the costs of cultivation and the treatments were evaluated. The weight and amount of corn per treatment were not affected by the association with the grass. After 60 days, in the intercropping treatments, the forage had one third ground cover, significantly different from the 44 % ground cover in the monoculture forages (p<0.05). When the grass was cut and fertilized after harvesting the corn, in all treatments, regrowth occurred after four weeks (p>0.05). The cost of establishing the forage was US$ 678 and US$ 806 for the intercropped treatment, per hectare. The forage intercropped with corn covered 49 % of the cost of establishing the forage. The resulting recommendation was to establish Toledo as an intercrop with corn planted at a distance of 1.5 m with three lines of forage between the rows.
