PERTUMBUHAN TANAMAN JATI (Tectona grandis L.f) DARI BERBAGAI RAS LAHAN DI PULAU MUNA

Abstract

Land race trial of teak species was carried out in Tampo, Muna Island, South East Sulawesi Province to assess the suitability of the land race on teak at eighteen months old. A Randomized Complete Block Design using 25 tree plots with 6 blocks as replications and 7 land races as treatments were used. The site of study is located at altitude about 5-10 m above sea level, with average temperature 25 °C to 27 °C and rainfall of 1,800 mm per year. The results showed that treatment had a highly significant effect on survival rate (49.33-82.67 %), but no significant effect was indicated in growth of height and diameter. Bonea land race showed highest growth (118.23 cm) and diameter (20.08 mm).
