Respon Pertumbuhan Bibit Kelapa Sawit (Elaeis Guineensis Jacq.) Terhadap Kombinasi Pupuk Npk Dengan Pupuk Organik Cair Limbah Ikan Nila
ABSTRACT
This research aims to determine the best combination of NPK fertilizer
with tilapia waste liquid organic fertilizer to the growth of oil palm seeds. This
research was conducted at Experimental Garden, Agriculture Faculty, University
of Riau, Pekanbaru. The research was conducted from May to September 2019.
This research was conducted experimentally using a completely randomized
design (CRD) with 7 treatments and 3 replications in order to obtain 21
experimental units. The treatments used were NPK fertilizer 2.50 g per plant
(control), NPK fertilizer 1.25 g per plant + LOF tilapia waste 25%, NPK fertilizer
1.25 g per plant + LOF tilapia waste 50%, NPK fertilizer 1.25 g per plant + LOF
tilapia waste 75%, NPK fertilizer 2.50 g per plant + LOF tilapia waste 25%, NPK
fertilizer 2.50 g per plant + LOF tilapia waste 50% and NPK fertilizer 2.50 g per
plant + LOF tilapia waste 75%. Parameters observed were seedling height (cm),
number of seed leaves (strands), seed bulb diameter (cm), seedling leaf area (cm2),
seedling root volume (cm3), seedling root shoot ratio and seed dry weight (g). The
data obtained were analyzed using analysis of variance and continued with the
Duncan's New Multiple Range Test (DNMRT) at the 5% level. The results
showed that the combination of NPK fertilizer treatment with tilapia waste LOF
affected the parameters of seed height, number of seed leaves, seed bulb diameter,
seedling leaf area, seed root volume, root shoot ratio and seed dry weight. The
combination of NPK fertilizer 1.25 g per plant + LOF tilapia waste 25% is the
best treatment to increase the growth of oil palm seedlings.
