PENGGUNAAN ARANG KOMPOS PADA MEDIA TUMBUH ANAKAN MAHONI

This report described results of an application of two kinds of compost charcoals on the growing media of mahoni seedlings(Swietenia rnacropbylla King)for 5-month duration. Objective of this study is to learn such applicationon the characteristics of seedlings growth. The two kinds of compost charcoals were : the one derived from tusam litters (Al) ; and the other from a mixture of litters and mahoni seeds (A.2). Results revealed that the application of compost charcoal (A1 and A2) each at 30% dosage could increase height of mahoni seedlings as much as 17.67 - 25.02 cm, which Is approximately 3 times greater than the control. The compost application also increased girth of mahoni seedling up to twice that of the controls. The application of compost charcoal at 40% dosage of either (Al) or (A2), however, showed a smaller increase in height and girth increament compared with the 30% dosage. Cummulatively,the application of compost charcoal could increase the seedling biomass by more than 400%
