PENGARUH PERBANDINGAN MEDIUM TOPSOIL DENGAN EFFLUENT DAN PEMBERIAN PUPUK NPK PADA BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.) DI PEMBIBITAN UTAMA
Abstract: The aim of this
research was to determine the effect ofmedium comparison (Topsoil : Effluent)
and get the best dose giving NPK fertilizer on oil palm seedling at main
nursery. This research was conducted at the experimental station of Agriculture
Faculty, University of Riau on April 2015 until July 2015. This research was
arranged on using Completely Rendomized Design (CDR) with two factorial: Factor
1;medium comparison , E0 (10kgTopsoil : 0 kg Effluent), E1 (9 kg Topsoil : 1 kg
Effluent), E2 (8 kg Topsoil : 2 kg Effluent), E3 (7 kg Topsoil : 3 kg
Effluent), E4 (6 kg Topsoil : 4 kg Effluent). Factor II; N0 (NPK 5 g/polybag),
N1( NPK 10 g/polybag), N2 (NPK 15 g/polybag) and replicated 3 times, so
abtained 45 unit experiment. Parameter observed were the accretion of plant
heigh, accretion of stump diameter, accretion of leaves number, root shoot
ratio and dry weight. The result showed that medium comparison(Topsoil :
Effluent) and giving NPK fertilizer interaction effect on accretion of leaves
number, but not significantly on accretion of plant heigh, accretionof stump
diameter, root shoot ratio and dry weight. The best result shows on 6 kg
Topsoil : 4 kg Effluent and NPK 15 g /polybag.Effluent treatment on oil palm
seedling effect to all parameters, whereas on the NPK giving effect to all
parameters except the accretionof stump diameter and root shoot ratio.
