Efeito da calagem sobre a produção de matéria seca de três gramíneas forrageiras

A greenhouse investigation was carried out to study the effects of liming on the dry matter (DM) production of the grasses Brachiaria brizantha (Hoscht.) Stapf. cv. Marandu, Andropogon gayanus Kunth cv. Planaltina and Panicum maximum Jacq cv. Aruana, cultivated on a Dark-Red Latosol, medium texture. The liming levels were obtained through the addition of carbonates in a Ca:Mg ratio of 4:1, necessary to increase the degree of base saturation (V%) to the following values; 4% (control), 20%, 36%, 52%, 68% and 84%. During the experimental period (180 days), four cuts were done to determine the DM production. The results indicated that the DM production was increased (P
