Abstract


This research was conducted to evaluate the agronomic characteristics and chemical composition of Gliricidia sepium grown under different residual heights in different seasons. Experimental design used was a complete randomized block in a split-plot. Plots consisted of three residual heights (70, 90 and 110 cm) and subplots were four seasons (fall, winter, spring and summer) with four replications. There was no effect (P>0.05) of 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) for residual height significant effects (P<0.05) were observed for DM, MM, ADF and EE in cutting seasons and residual height. Gliricidia sepium can be cut in residual height of 70 cm, with better agronomic characteristics and chemical composition in fall.
