PENGARUH PEMBERIAN BEBERAPA DOSIS KOMPOS KULIT BUAH KAKAO DAN DOLOMIT TERHADAP PERTUMBUHAN BIBIT KAKAO (Theobroma cacao L.) DI MEDIA ULTISOL
Abstract: The aim of research
to determine the effect of compost main pod husks and dolomite as well as their
interaction on the growth of cocoa seedlings in media ultisol. Research conducted
at the Experimental Farm, Faculty of Agriculture, University of Riau from
November 2015 until February 2016. Research in the form of factorial experiment
using completely randomized design (CRD). The first factor pod husks compost
comprises four levels (0, 75, 100 and 125 g / polybag) and the second factor
dolomite consists of three levels (0, 10, and 20 g / polybag), each combination
treatment was repeated 3 times. Parameters measured were plant height, leaf
number, stem diameter, and leaf area. Each parameter the observed data were
statistically analyzed using analysis of variance and test of Duncan's New
Multiple Range Test (DNMRT) at 5% level. The results showed the effect of
compost pod husks dose of 125 g / polybag significantly increased plant height,
stem diameter, number of leaves and leaf area while dolomite dose of 20 g /
polybag no real effect except leaf area compared with no treatment. Interaction
pod husks compost dose of 100 g / polybag and dolomite dose of 20 g / polybag
increase stem diameter, number of leaves and leaf area significantly compared
without compost pod husks and dolomite but less tangible than other
combinations.
