HEVEA AND COCOA ASSOCIATION IN RONDONIA STATE. The present paper describe the results of an agroforestry system rubber and cocoa, in Ouro Preto D'Oeste, state of Rondonia. The experimental design was randomized blocks, in factorial 3X3, with two aditional treatments, and three replications. The factors were: spacing (2,5 m x 3,0 m; 3,0 m x 3,0 m and 3,5 m x 3,0 m) and density (two, three and four rows between doble rows of rubber) of cocoa . The aditional treatments were hevea and cocoa in monoculture with 6,0 m x 3,0 m and 2,5 m x 3,0 m spacings, respectively. The parameters measured were rubber tree vigour and latex production and cocoa yield . Under experimental conditions, it was observed that the rubber vigour was not affected in consortium with coco a, that consortium improved hevea culture, and that the best agroforestry system was rubber spaced 6,0 m x 3,0 m in double rows, associated with two lines of cocoa spaced 2,5m x 3,Om.
