PENGARUH TANAH MINERAL DAN ABU JANJANG KELAPA SAWIT PADA MEDIUM GAMBUT TERHADAP PERTUMBUHAN BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.) DI PEMBIBITAN UTAMA
Abstract: The research aimed
to determine the effect of mineral soil and oil palm bunch ash on peat medium
on the growth of oil palm seedling (Elaeis guineensis Jacq.) in main nursery.
The research was conducted from April to August 2015. This research is a 4 x 4
factorial experiment arranged in a completely randomized design (CRD). The
first factor is effect mineral soil consist of four levels: 0, 50, 75 and 100
g/5,6 kg peat soil. The second factor is effect oil palm bunch ash consist of
four levels: 0, 25, 50 and 75 g/5,6 kg peat soil, thus there are 16
combinations of treatment is repeated three times, so there are 48 experimental
units. Data were analyzed using ANOVA and continued with further test Duncan’s
New Multiple Range Test (DNMRT) at 5%. The results showed that the combination
of mineral soil 10 ton/ha with oil palm
bunch ash 15 ton/ha increase height and seedling dry weight. Giving oil palm bunch ash increase
hight and tends to increase the volume of roots, dry weight and ratio root
crown. Giving mineral soil up to 15 ton/ha tends to increase the volume of
roots, dry weight and ratio root crown.
