PENGARUH PUPUK HIJAU Azolla microphylla DAN NPK TERHADAP PERTUMBUHAN KELAPA SAWIT (Elaeis guineensis Jacq.) FASE MAIN NURSERY
Abstract: This study aims to
determine the effect of the interaction and the single factor green manure,
Azolla microphylla and NPK fertilizer on plant oil palm in the main nursery as
well as getting the best dose. This research has been conducted in the
experimental garden of Faculty of Agriculture, University of Riau in November
2015 to March 2016. The study was conducted experimentally using a completely
randomized design (CRD) factorial, consisting of two factors and three
replications. The first factor is Green manure Azolla Microphylla with 6 levels
(0, 20, 40, 60, 80 and 100 / polybag) and the second factor is NPK fertilizer
with 4 levels (0, 10, 20 and 30 g / polybag). The parameters measured were the
increase of plant height, , in the number of leaves, stem diameter increase,
root volume, dry weight, the uptake of N in the leaves and the leaves outbreak.
The results were analyzed statistically using Analysis Of Variance (ANOVA). The results of the analysis
of the test manifold followed by Duncan's New Multiple Range Test (DNMRT) level
of 5%. The results showed that administration of green manure, Azolla
microphylla and NPK on oil palm seedlings no real effect on the increase of
plant height, stem diameter increase, in the number of leaves root volume and
dry wight . In morphology, palm trees aged 7 months treated green manure Azolla
microphylla and NPK grow well, but development in general leaves only reached
the stage of development bifurcate. Oil palm seedlings were given the green
manure Azolla microphylla with a dose of 40 g / polybag and NPK at a dose of 10
g / polybag provide good seedling growth and nutrient uptake of N highest.
