Growth biometry of Farm grown teak (Tectona grandis Linn. F) in high rainfall zone of Tamil Nadu

Teak is an extremely popular timber species regarded as a paragon among timber due to its natural durability, stability and other wood properties. The growth biometry of farm grown teak is a critical aspect of understanding and is crucial for optimizing the cultivation of this valuable hardwood tree under farm settings. The present investigation was carried out in 6 revenue blocks in four age classes under High Rainfall Agro climatic zone in Kanyakumari district of Tamil Nadu to determine the growth and correlate the age with growth biometry of farm grown teak. The boundary plantations of 15-20 years age class, has the maximum DBH (0.285 m), height (11.35 m) and volume (0.760 m 3 ). Positive correlation was observed between diameter at breast height (dbh) (k=0.985, p <0.05), total height (k=0.999, p <0.01), total volume (k=0.922, p <0.05) with the age of the plantations. High Rainfall zone is more suitable for cultivation of teak in farm land conditions owing to the favourable climatic conditions coupled with management practices followed in tree cultivation.
