Leucaena leucocephalais a fast‐growing tree that can provide both high quality forage and firewood. The objective of this trial was to determine the optimum height and frequency of cutting for both wood and forage production. Cutting heights at 0.3 m, 0.6 m and 1.0 m were superimposed on 3‐month and 6‐month cutting frequencies on mature rows ofL. leucocephalafor three years. Effects of year or its interaction with the other factors were not significant (P≥0.10). There was an increase (P=0.07) in wood production but not forage production (P≥0.10) with the longer interval. Cutting height had an effect on forage (P<0.001) production, with 5.47 t ha−1a−1for the 0.3‐m height, 7.62 t ha−1a−1for the 0.7‐m height, and 8.71 t ha−1a−1for the 1.0‐m height. Cutting height also had an effect on wood production (P<0.001), with 7.22 t hd−1a−1for the 0.3‐m height, 9.33 t ha−1a−1for the 0.7‐mheight, and 11.55 t hd−1a−1for the 1.0‐m height. In this experiment, the six‐month interval produced more wood than the three‐month interval, but there were no differences in quantity of forage dry matter inL. leucocephala; there were advantages in both wood and forage production with the taller trunk base.
