PENGARUH PEMBERIAN PUPUK KANDANG AYAM DAN ZAT PENGATUR TUMBUH GIBERELIN TERHADAP PERTUMBUHAN BIBIT KOPI ARABIKA (Coffea arabica L.)
Abstract: This Researh aims to
determine the effect of chicken manure and plant growth regulator of giberelin
and good dose on the growth coffee arabika seeds. Research was conducted at the
experimental farm of Agriculture Faculty, University of Riau from May to August
2014. This research utilized Split Plot Design, consist of 2 factors. The first
factor, consentration of plant growth regulator as main plot were: without
plant growth regulator, consentration 20 ppm and consentration 60 ppm. The
second factor, chicken manure as sub plot were: without chicken manure, chiken
manure 15 g/plant (10 ton/ha), chicken manure 22.5 g/plant (15 ton/ha), chicken
manure 30 g/plant (20 ton/ha). The treatment with 3 replications and every
replication with 3 units seeds so obtained 108 units experiment. Parameters
observed were the increase of seeds height, leaves number, total wide of leaves
seeds, root volume and root crown ratio. Data were analyzed using Analysis of
Variance (ANOVA). The data obtained were further tested by Least Significant
Diference (LSD) at the level 5 %. Based on the result it can be concluded that
is not apparent after a statistical analysis on the parameters except the total
wide of leaves seeds. Giving chicken
manure at the dose of 30 g/plant (20 ton/ha) and plant growth regulator of
giberelin 60 ppm has not followed the
maximum result in all parameters tested.
