【 摘 要 】

A field trial was carried out to evaluate the establishment methods (Furrow only: row 1,5 and 1,0 m apart at one time; 1.5 and 1.0 at two and three times, respectively; Plowing and horrowing: row 1,0 apart), limestone (25, 50, 75 e 100% of necessity of limestone, obtained by Al, Ca e Mg exchangeable), gypsum (0, 230, 940, 1.880 e 2.820 kg/ha) and P2O5 (50, 100, 150, 200 e 250 kg/ha) on minerals concentration (P, K, Ca, Mg e S); crude protein (CP), neutral detergent fiber (NDF), acid detergent acid (ADF) and in vitro dry matter disappearance (IVDMD) of Brachiaria decumbens and Stylosanthes guianensis cv.Mineirão pasture mixture. The establishing methods at two and three times increased K concentration in the brachiaria and Ca concentration in the stylosanthes. The plowing and horrowing of soil provided higher CP concentration in the brachiaria. The substitution of the limestone CaO by gypsum CaO caused an increase in the S, Ca and CP concentration in both species and decreased of NDF of grass DM. The P2O5 increased the P, PB concentration and IVDMD and decreased NDF in DM of brachiaria improving the nutritive value of forage.
