PENGARUH PENAMBAHAN GAMBUT DAN SEKAM PADI PADA MEDIA TANAM ALLUVIAL TERHADAP PERTUMBUHAN BIBIT MAHONI (Swietenia mahagoni) DI PERSEMAIAN
Abstract: Mahogany is a
pioneer plant that can grow well in brackish sand near beach. Mahogany trees
are also widely used as a bioremediation agent. Mahogany plants that will be
used as a bioremediation agent must be a good seed , one of the factors that
must be corrected to obtain good seed is by providing a good planting media as
well. In West Kalimantan, there are a lot of alluvial soil that can be used as
a medium of nursery . Alluvial soil is generally acidic (low pH) and nutrient
poor so it will be a problem when it is used as a medium of nursery. The
attempts to overcome this problem is by adding peat and rice husk on alluvial
palanting media . This study was aimed to determine the effect of peat and rice
husk on alluvial planting media on the growth of mahogany seedlings in the
seedbed. According to analysis carried out showed there were not significantly
different between treatments, but when viewed from the mean of plant height and
the number of leaf growth, treatment B with the comparison of alluvial soil ,
peat and rice hulls (5:5:0) was the highest growth of trunks and leaves . Based
on the observation, the largest growth of trunk diameter was on treatment C
that was 0:59 mm. The difference of diameter growth at every treatment is
essentially influenced by many factors, both external factors from natural (
climate and environment ) and internal factors (genetic) of seed plants.
