Abstract

This research aims to know the growth of oil palm seeds and composition of empty oil palm bunches of compost and ex- coal mining soil as a medium for planting oil palm seedlings in pre nursery. This research consists of 4 level of treatment, namely k
0
: top soil as a control, k
: the composition of media from ex-coal mining soil and
empty oil palm bunches compost (75%: 25%), k
1
: the composition of media from excoal
mining
soil
and
empty palm bunches of compost (50%: 50%), k
2
: the composition
of media from ex-coal mining soil and empty oil palm bunches of compost (25%: 75%).
Each treatment was repeated 6 times, so there are 24 units of treatment. The variables
measured in this study are number of leaves, stem diameter, total dry weight, leaf area
and dry weight of roots. The results showed that the composition of media from ex-coal
mining soil and empty palm bunches of compost can increase oil palm growth seedling.
The treatment of 75 % of media from ex coal mining soil: 25% empty of oil palm
bunches of compost show the highly number of leaves, stem diameter, total dry weight,
leaf area, and dry weight of roots.
