Abstract

Studies on growth and biomass accumulation were conducted in 5 years old Hopeaodorata plantation in Segamat, Johor. The objectives of this study are, firstly, to determine and compare the growth of H. odorata on three different soil series of Ultisols(Baling, Rengam and Kuala Berang) and secondly, to develop an allometric equation to estimate the biomass accumulation of H. odorataplantation in three different soil series five years after planting. Results of this study show that, the highest growth performances in terms of diameter and height was found in the Baling soil series, followed by the Rengam and Kuala Berang soil series. The highest stem volume and biomass accumulation were recorded at Baling (33.75 m3 h-1 and 46.20 t ha-1, respectively), followed by the Rengam (33.66 m3 h-1 and 42.90t ha-1, respectively) and Kuala Berang soil series (21.54 m3 h-1 and 32.47 t ha-1, respectively). The best model for site-specific equations developed from the independent variable D are recommended for estimating tree component biomass and stem volume in each site. The information of this study indicates that the productivity of forest plantation is correlated by soil type. This study also shows that, the good soil type for Hopeaodorata grow this in Baling soil series.
