The experiment was accomplished in the experimental field of Univale from december/1998 to may/1999. Three systems comprising mayze intercrop with bean were assessed: Double-spaced rows of mayze 0,5 m and 1,5 m between couples with three bean rows (system 1); simple-spaced rows of mayze 1,0 m with a row of bean in the middle (system 2); simple rows of mayze 1,0 m with two rows of bean in the middle (system 3); as well as single crops. The mayze utilized was the hybrid AG1051 and the bean was Carioca CI257. Both species were sowed simultaneously and fertilized. Bean yield component factors and productivity were assessed. As for production of green mass for silage and productivity were assessed as well. In the intercrop system, the pod number per plant suffered a significant reduction in relation to the single crop. Such factor was the most important to productivity decreased. The components seed per pod number and seed weight showed no difference from single plantation. In mayze, the doubled-row sowing significantly reduced productivity. Intercrop system 3 presented higher index of area equivalency when grain and mayze silage production was concenrned.
