CARBON ESTIMATION AND CARBON YIELD TABLE FOR TEAK (<em>TECTONA</em> <em>GRANDIS</em>) AT CAUVERY DELTA ZONE OF TAMIL NADU

Abstract

Teak plantations are generally managed for timber production and presently there is an increasing interest in understanding the carbon stocks of Teak plantation. A study was developed on carbon yield table for Teak in Cauvery delta zone of Tamil Nadu, India and field data was taken from 15 sample plots of 30 m × 30 m size in different age classes, for instance 4–5 years, 7–8 years, 12–13 years, 15–16 years, 18–19 years, 23–24 years, 40–41 years and 46–47 years, respectively. Tree height and diameter of 2 meter segments from ground level to top height were measured and the average merchantable volume of 1.246 m3 and carbon content of 373.80 kg were recorded in the age class of 46–47 years. The carbon model constructed for Tectona grandis using multiple linear regression was Y = -113.001+2.8616(Age)-3.6946(Total height)+1245.813(Diameter). The carbon yield table was constructed using the age class, top height class and diameter class. The overall observation of the study concluded that, the best fit carbon yield models were developed for T. grandis with 91 per cent accuracy by comparing actual carbon stock and predicted carbon stock.
