At 4 week intervals selected groups of Gliricidia sepium trees were cut to 1 m in height to give 4 growing season cutting treatments and an uncut control. This trial was carried out from February to September. At each harvest, the height of the individual tree was recorded and the number of primary branches arising from the base was counted. It appeared that previous cutting history had no effect on leaf retention in Gliricidia in a sub-tropical environment once the minimum temperature in the cool dry season falls below 10 degrees C. Another experiment was carried out in the month of November in which the following treatments were evaluated: 6 harvests at monthly intervals over the growing period (October-April); 3 harvests at 2-monthly intervals; and one harvest at the end of the growing period (April). The results suggest that Gliricidia would be best utilized as a supplement for late autumn/early winter grazing and that for maximum yields at this time the trees should be left uncut during the growing season
