Conteúdo:	It was conducted a study of reclamation of degraded pasture of Brachiaria decumbens, comparing the following treatments: 1) conventional broadcasting of fertilizer and disking; 2) reclamation as in 1, plus the introduction of Calopogonium mucunoides and Stylosanthes guianensis; 3)"Barreirao" system (recuperation using upland rice, cropped simultaneously with the grass); 4)conventional system of upland rice (soil preparation using a heavy plougher and disking, low level of fertilizer, without liming); 5) modifield Barreirao-1 (including liming and increasing fertilizer level); 6) modifield Barreira-2 (as treatment; 5)but weeding 20 days after rice emergence); and 7) control. There was a significant increase in the grass dry matter production in the treatment without rice compared to the control, specially the green faction of leaves and stems. The grass production was afected by the rice in the remaning treatments, due to a significant increase of its biomass. The benefits of the rice grain yeild were not enough to account fully for the recuperation costs, but helped substantially in that matter. The real benefits of the pasture reclamation, however, would be truly available only over time.
