PENGARUH BEBERAPA BAHAN ORGANIK TERHADAP MAKROFAUNA TANAH DAN PERTUMBUHAN KELAPA SAWIT (Elaeis guineensis Jacq.)
Abstract: Palm oil (Elaeis
guineensis Jacq.) is a plantation commodity which plays important role in
economics of Indonesia. Palm oil can grow at various ground type by paying
attention to the soil characteristics including soil biology. Soil biology like
existence of soil macrofauna depend on availibility of energy such as organic
matter and decomposed it, so that can maintain the soil productivity. This
research aims to determine the effect of organic matters and to determine the
better of organic matters for soil macrofauna and palm oil growth. This
research has been conducted at the experimental farm of Agricultural Faculty
Riau University on May to August 2015. This research was carried out
experimentally by using randomized block design (RBD) with 4 treatments
(without organic matter, palm oil empty fruit bunch, sawdust and congongrass of
10 kg/plant) and 6 replications, so there are 24 experimental units.The data
obtained were analyzed using ANOVA and followed by further test DNMRT at 5%
level. The result showed that the application of 10 kg/plant sawdustgave the
best for number of individu, number of type and population densityof soil
macrofauna. The application of 10 kg/plant palm oil empty fruit bunch showed
the best results for increasing of plant height, increasing number of fronds,
increasing of fronds length and increasing of leaves. Organic matter which
showed the best result for soil macrofauna was not show the best results for
oil palm growth.
