PEMBERIAN KOMPOS TKKS DAN COCOPEAT PADA TANAH SUBSOIL ULTISOL TERHADAP PERTUMBUHAN BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.) DI PRE NURSERY
Abstract: Palm oil (Elaeis
guineensis Jacq.) is a plantation crop which is quite important in Indonesia
because it accounts for foreign exchange and create employment that is high
enough. Palm oil empty fruit bunches (EFB) is estimated at 20% of fresh fruit
bunches ( FFB ) and coco in (cocopeat) are very much in Riau as raw material
for fertilizer / compost. Subsoil ultisol a bottom layer of soil with
sufficient depth within therefore very potential as a medium of palm oil nursery
but has a low fertility signified by the nature of physics, chemistry and
biology poor. Organic matter such as EFB compost and cocopeat can improve
physical, chemical and biological subsoil ultisol. The research aimed to study
the effect of EFB compost , cocopeat and a mixture of both the subsoil ultisol
medium on the growth of palm oil seedlings in pre nursery. The study was
conducted at the experimental station of Agriculture Faculty of the University
of Riau from June to August , 2015. Research conducted an experiment using a
completely randomized design (CRD) consisting of 6 treatments (K0 : without
treatment , K1 : 100 g cocopeat , K2 : 100 g compost EFB , K3 : 50 g compost
EFB + 50 g cocopeat , K4 : 75 g of compost EFB + 25 g cocopeat and K5 : 25 g
compost cocopeat EFB + 75 g per plant) each repeated 4 times. The results
showed treament EFB compost 50 g and cocopeat 50 g produce in the growth palm
oil seedlings better than the other treatments on medium subsoil ultisol in pre
nursery.
