Abstract
This research was conducted to evaluate the agronomic characteristics and chemical composition of Gliricidia sepium (Jacq.) Steud grown under different residual heights in different seasons. The experimental design used was a complete randomized block in a split-plot. The plots consisted of three residual heights (70, 90 and 110 cm), and the subplots were four seasons (fall, winter, spring and summer) with four replicates. There was no (P>0.05) interaction between season and residual heights for agronomic characteristics. However, these features were influenced by the cutting season, with no significant effect (P>0.05) on residual height. Significant effects (P<0.05) were observed for dry matter, mineral matter, acid detergent fiber and ether extract in cutting seasons and residual height. Gliricidia sepium can be cut at a residual height of 70 cm, with better agronomic characteristics and chemical composition occurring in the fall.
