Volume and growth model for Neolamarckia cadamba plantation in Coimbatore district of Tamil Nadu

Abstract

The study was conducted to identify the volume, growth attribute factors and design to construct the growth models of Neolamarckia cadamba plantation in Coimbatore district of Tamil Nadu. Different age stages of plantations viz., two to three, three to four, four to five eleven to twelve, twelve to thirteen, thirteen to fourteen, fourteen to fifteen, and fifteen to sixteen years were used for the study. Biometric parameters were collected on each plantation such as tree girth, tree height and tree diameter by using measuring tape and Haga altimeter respectively during 2018, 2019 and 2020. The study was carried out farmer’s plantation of Narashipuram & Devanathapuram and FC&RI, Mettupalayam of Coimbatore district to develop the growth model for Neolamarckia cadamba. The average volume of Kadam in Thondamuthur plantations was 1.147m3 it was in the age class 17-18 years. In Narashipuram plantation, the volume was 0.523m3 at 14-15 years. In FC&RI, Mettupalayam the volume was 0.0893m3 at age class 3-4 years. Deriving growth model for fast growing and high yielding Kadam trees would help the farming community to easily predict the volume as well as yield. The study results concludes that power model is the Best-fit for volume growth prediction equation developed for Neolamarckia cadamba plantation in Coimbatore district of Tamil Nadu Y = 18.299 x 2..5108
