PENGARUH MIKORIZA DAN ARANG PADA MEDIA TUMBUH TERHADAP PERTUMBUHAN SEMAI MAHONI ( SWIETENIA MACROPHYLLA KING.)
ABSTRACT: Mahogany (Swietania
macruphylla King) is an introduced timber species and a priority in the current
development of plantation forests. This species has a quite good market in the
timber trade in indonesia. It is used as material for furniture, building and
construction. Charcoal contains C (carbon) elements, and pores containing
hydrocarbons and other organic compounds, i.e. water, nitrogen , and sulfur. The objective of this
study was to determine the effect of mycorrhizal and charcoal on growth media
on the mahogany (Swietenia macrophylla King.) seedling growth. The study was
conducted from March to May 2014 in Permanent Nursery of BPDAS Palu-Poso-
Tadulako University, Palu, Central Sulawesi. This study was organized with a
completely randomized design (CDR), which consisted of 7 treatments, namely: MO
= top soil media without mycorrhiza (control); M1= top soil + micorrhiza; AK =
top soil + wood charcol; AT = top soil + coconut shell charcoal; MAK = top soil
+ mycorrhiza + wood charcoal; MAT = top soil + mycorrhiza + coconut shell
charcoal; MKT = top soil + mycorrhiza + wood charcoal + coconut shell charcoal.
These treatments were replicated five times each, so tge total sample were 35
experimental units. The honestly significant difference test (HSD) was used to
determine the difference between treatments. The study result indicate that
treatments (mycorrhizal soil, wood charcoal, coconut shell charcoal, wood
charcoal + mycorhizal, coconut shell charcoal+ mycorrhizal, wood charcoal
mycorrhizal + coconut shell carcoal) might increase significantle growth of
mahogany seedlings compared to the
control (without application of FMA). The seven treatments give significant
difference to the height, number of leaves, and the diameter of mahogany
seedling except for the control treatment.
