Growth and volume productivity of farm grown teak (Tectona grandis Linn. F) in cauvery delta zone of Tamil Nadu

Abstract

A natural Teak resource is available only in few tropical and sub-tropical countries like India, Myanmar, Thailand etc. India is the leading exporter of teak resources in early decades, but presently the country is becoming the major net importer of teak resources in order to meet their requirements. Based on the constrains, the present study was conducted in farmlands under Cauvery delta zone (CDZ) of Tamil Nadu to analyze the available teak resources and their influence on growth and volume production. The growth biometrics and volume production of Teak among different block and boundary plantations of farm grown teak in different age class were recorded in cauvery delta agroclimatic zone of Tamil Nadu. On comparing both plantations, the present study revealed that growth biometrics is significant in boundary plantations of 15-20 years age class attaining maximum DBH (0.201 m), height (9.8 m) and volume (0.282 m3). Hence, it is concluded that under farmland condition, Cauvery delta zone is more superior zone for teak boundary plantation due to the influence of optimum climatic and edaphic factors.
