APLIKASI PUPUK HIJAU Mucuna bracteata PADA BEBERAPA JENIS MEDIA BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.)DI MAIN-NURSERY
Abstract: The purpose of this
research to determine combination of green fertilizer Mucuna bracteata in some
type of soil media and single-factor as well getting the best dose to the
growth of oil palm seedlings. This reseach uses three type of soil media namely, sub soil Ultisol taken
from desa batu belah, kab.kampar, province Riau, sub soil Inceptisol taken from
Faculty of Agriculture, University of Riau and peat soil taken from Desa Rimbo
Panjang, Kab. Kampar, Province Riau as
growing media.Three type of media is utilized as soil media treatment of soil
mix for growing oil palm seed is ground Ultisol sub soil mixed with peat soil
and sub soil Inceptisolmixed with peat soil. Treatment of the soil media mix
with appropriate comparison would be able to increase the growth of oil palm
seedlings that can be developed with green fertilizer Mucuna bracteata
appropriate and in accordance with the ability of the soil. This research
exprimental units were arranged in
Factorial Competely Randomized Design
with three replication. The first factor is composed of green fertilizer mucuna
bracteata P0: Green fertilizer mucuna dose 0 g/polybag, P1: Green fertilizer
mucuna dose 10,9 g/polybag, P2: Green fertilizer mucuna dose 21,6 g/polybag,
P3: Green fertilizer mucuna dose 32,4 g/polybag. The second factor comprises
several type of soil medium consisting of T1: Sub soil Ultisol + Peat soil, T2:
Sub soil Inceptisol + Peat soil. Parameters studiet were an increase plant
height, leaf number increase, the increase in diameter stump, root volume, root
canopy ratio, dry weight and visual rupture leaves. The results showed that
administration of mucuna green
fertilizer 21.6 g/polybag on the type of media subsoil Inceptisol +
peat soil gives the best growth to the growth of oil palm seedlings. It
is the same with the standards recommended by the research center of Indonesia
oil palm seedlings.
