Pertumbuhan dan Serapan Nitrogen Bibit Kelapa Sawit (Elaeis guineensis Jacq.) Pada Fase Main-Nursery Di Beberapa Medium Tumbuh Dengan Efek Sisa Pupuk Organik
Abstract: This research aimed
to determine the response of the growth of oil palm seedlings and how much
nitrogen can reserve by oil palm seedlings on different organic fertilizer
sources with some planting medium. This research has done in experimental
plantation Agriculture Faculty, University of Riau from October until December
2012. This research used completely randomized factorial design with two
treatment factors and three replications. The first factor was source of
residue effect of different organic fertilizer include P0: without fertilizer,
P1: bird’s manure, P2: Sludge fertilizer, P3: liquid organic fertilizer. The
second factor was plant medium as T1: PMK soil, T2: Peat soil, T3: the
combination of PMK soil and Peat Soil 50:50. The result showed that the best
treatment was of residue effect of liquid organic fertilizer in PMK and Peat
soil medium because its can be inclined grow up plant height, stump diameter,
amount of leaves, root volume, seedling dry weight and the reserve of nitrogen.
Treatment of plant medium was not significant for all parameters. Interaction
between the two treatments significantly effect plant height, seedling dry
weight and the reserve of nitrogen, but non significantly for amount of leaves,
stump diameter and root volume.
