Hashim Md Noor
Teak (Tectona grandis) stumps were transplanted in a lateriticsite at a spacing of 3 x 3 m at Mata Ayer Forest Reserve, Perlis. About 50% mortality occurred in the first three years after planting. Mechanical impediment to root growth and water stress were suspected to be the main factors for high mortality. Intersections of mean annual increment and current annual increment curves of height and diameter showed that maximum height and diameter increments were reached at ages four to five years after planting. This growth stage was also the best time to conductthe first thinning. Recommendations to improve survival and productivity of teak grown on lateritic soils are given.
