%X A major problem is tropical pasture conditions in acid soils of low fertility. In this context the condition of nutrition of forage plants has low availability of phosphorus (P). The present study aimed to evaluate the effect of two phosphate sources (meat and bone meals and superphosphate) in dry matter production of Tifton (Cynodon dactylon L.). The experiment was conducted from March to July 2011, in the experimental farm of UNIR, Rolim de Moura, RO. The experiment was carried out in buckets of 10 kg of soil. Treatments were the addition of increasing doses of P2O5 (0, 100, 200 and 300 kg ha-1) plots with nitrogen fertilization (20 kg ha-1) in each section (30 days), there is still a witness (only N) and absolute control (no N and no P). The randomized blocks design was used with five replicates (3x2+2). Variable analysis, had different levels of production in relation to the cutting times can be attributed to the difference in solubility between the sources of P2O5 studied. In terms of response in four sections, the production levels of dry matter generated by the meat and bones proved effective in relation to single super phosphate, ranging from 94%, 66% and 78% compared with the doses 100, 200 and 300 kg ha-1, respectively. The meat and bone meal produced satisfactory answers in relation to dry matter production of Tifton, compared to conventional fertilization.
