Abstract
A study was carried out at the Forest College and Research Institute (Tamil Nadu) to elicit information on the growth and yield of teak (Tectona grandis L.f.) under irrigated condition. The oldest (11 year) available irrigated teak had a mean volume of 0.109 m3 (3.85 ft3) tree1 with a Mean annual Volume Increment (MAI) of 0.0099 m3 tree1. Based on this, the volume at 20 years is extrapolated to be 0.199 m3 (7.00 ft3) tree1. Based on the diameter classes of 11 year wood lot, only the diameter class of 15.1-25.0 cm is expected to attain a girth of 90 cm in 20 years and trunk with a GBH of 90 cm and above alone is considered as a log. This class of trees accounted for only 13.7% in 11 year wood-lot raised.
