DescriptionTeak plantations, 3 to 16 years old, were thinned and fertilized in an effort to increase productivity. The best single method for increasing rate of tree increment was removal of competitors. Larger trees had a faster basal area increment but slower height growth than smaller trees on the same site conditions. Height growth was greater in the areas with higher rainfall, but basal area increment was not. Both height and basal area growth were greater on the andesite-derived alluvial sites than on the residual soils over limestone. Basal area increment was correlated with addition of phosphorus; total height growth was correlated with added potassium. The effect was quite minor in both cases, and neither height nor basal area was signifi cantly influenced by added nitrogen, calcium, nor magnesium.
