PENGARUH SLUDGE LIMBAH KELAPA SAWIT DAN PUPUK NPKMg (15:15:6:4) DALAM MEDIA TANAM ULTISOL TERHADAP PERTUMBUHAN BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.) DI MAIN NURSERY
Abstract: The research aimed
to determine the effect of interaction giving palm oil waste sludge and NPKMg
(15:15:6:4) fertilizer on Ultisol and get the best treatment to the growth of
palm oil (Elaeis guineensis Jacq.) seedlings in main nursery. The research was
conducted at the experimental field of the Faculty of Agriculture, University
of Riau. This research was conducted from March to July 2015. The research used
Completely Randomized Design factorial that consisting of two factors. The
first factor is palm oil waste sludge (S) consists of 4 levels. The second
factor is the NPKMg (15:15:6:4) fertilizer (P) consists of 3 levels. Both these
factors resulted in 12 treatment combinations, each combination made 3 replications,
so that there are 36 experimental units. Each experimental unit consisted of 2
plants, so the total crop was 72 plants. Parameters measured were the increase
seedling height, the number of leaves increase, the increase hump diameter,
leaf area, root volume and dry weight. Data were analyzed by analysis of
variance and further tested using Duncan`s New Multiple Range Test at the level
of 5%.The results of the research showed that there is interaction between
giving application palm oil waste sludge and NPKMg fertilizer on increase of
seed hump diameter dan seed dry weight. Combination treatment of sludge dose
with 100 g/plant and NPKMg fertilizer with 10,5 g/plant is the best treatment
that can be recommended to get the growth palm oil seedling in main nursery on
Ultisol.
