Description:	The agronomic performance of seven forage grasses, under a mature rubber plantation, was assessed in a cutting trial carried out at Porto Velho, Rondônia. During the rainy season, the higher dry matter yields were obtained with B. brizantha, P. atratum BRA-9610 and B. humidicola. During the dry season, the grasses more productive were B. brizantha and P. atratum BRA-9610. In both seasons, magnesium and potassium contents did not vary among grasses. During the rainy season, the higher nitrogen and phosphorus contents were obtained with P. regnelli BRA-0159 and, P. guenoarum BRA-3824 and B. humidicola, respectively, while P. atratum BRA-9610 and B. humidicola provided higher contents of calcium. During the dry season, P. regnelli BRA-0159 showed the highest nitrogen content, while B. humidicola and B. brizantha gave the highest phosphorus and calcium contents. In order to obtain greater forage yields with better quality, the grasses more promising for pasture establishment in a silvipastoral systems were B. brizantha, B. humidicola and P. atratum BRA-9610.
