Abstract

Two tropical grass species under increasing percent base saturation were grown in greenhouse in order to be determined the ratio on which best response is reached on dry matter yield basis. The four percent base saturation rates were 10, 30, 50 and 70%, provided by an addition of calcium and magnesium oxides equivalent to 0; 1,2; 2,4 and 3,6 t ha-1 of lime, with five replicates. A complete random design for statistical analysis was used. Soil analysis at the 20th day showed an increase in pH values and percent base saturation and a decrease in Al3+ values due to liming. There was a significant effect of increasing percent base saturation represented by an increasing of dry matter up to 43% for Marandu grass (Brachiaria brizantha Stapf. cv. Marandu) and up to 47% for guinea grass (Panicum maximum Jacq. cv. IZ-I). The effect of liming in increasing tillering ocurred up to 37% of percent base saturation for guinea grass in the first cutting. There was a predominance in increasing of total quantity of nitrogen by aerial parts due to the treatments.
