PENGARUH DOSIS PUPUK NPK TERHADAP PERTUMBUHAN BIBIT JABON MERAH (Anthocephalus macrophyllus) PADA MEDIA CAMPURAN TANAH PMK, KOMPOS DAN PASIR
Abstract: The red jabon
(Anthocephalus macrophyllus) is one type that has an important role in the forest
and land rehabilitation activities, beacause the cycle is shorter so it can
provide high production in short time. The purpose of this research is to get
the dose of appropriate NPK fertilizer for the red jabon growth on mixed media
ultisol soil, compost and sand. The problem is how many doses of NPK fertilizer
should be given to the plant. This research is an experimental research
prepared using Completely Random Design methode that which consisted of 6
treatment with 4 replication so there is a 24 unit experiments. Treatment without
fertilizer is control (P 0 ), fertilizer treatment of NPK with the dose 0,5 g
plant/(P 1 ), fertilizer treatment of NPK with the dose 1 g/plant (P 2 ), fertilizer
treatment of NPK with the dose 1.5 g/plant (P 3 ), fertilizer treatment of NPK
with the dose 2 g/plant (P 4 ), fertilizer treatment of NPK with the dose 2,5
g/plant (P 5 ). The result of research showed treatment of giving NPK
fertilizer with the kinds of dose on the red Jabon seed with mix media of ultisol
soil, compost and sand (2:1:1) not yet the real effect to height, diameter and
number of leaves.
