| Abstract: | The effect of cutting height and cutting interval on dry matter production of Leucaena leucocephala (Lam) De Wit was investigated at Njala, Sierra Leone using three year old Leucaena trees. Four cutting heights, (25, 50, 75 and 100 cm), and two cutting intervals (one and three months), were adopted.Dry matter yields were highest at the 75 and 100 cm cutting heights, especially at the longer, three-monthly, cutting interval. They were significantly reduced by more frequent cutting, probably due to the increased number of recovery phases.Leaf nitrogen yields per tree for trees cut at three-monthly intervals were over twice as high as the total yields obtained from monthly cutting over the same period. |
