PENGARUH PEMBERIAN CAMPURAN KOMPOS KULIT BUAH KAKAO DENGAN KOMPOS TANDAN KOSONG KELAPA SAWIT TERHADAP PERTUMBUHAN BIBIT KAKAO (Theobroma cacao L.) PADA MEDIUM SUBSOIL ULTISOL
ABSTRACT: The purpose of this
research is to determine the effect a mixture of compost cocoa exocarpium with
compost TKKS and to get the best treatment combination for the growth of cocoa
in the subsoil medium ultisol. This research was conducted in the experimental
field and Laboratory of Production Faculty of Agriculture, University of Riau
in Campus Binawidya Km 12.5 Simpang Baru Pekanbaru. This research was conducted
from March to June 2016. The research used Completely Randomized Design
nonfactorial that consisting of 6 treatment and 3 replications, so that there
are 18 experimental units. Each experimental unit consisted of three plants and
two seeds sampled, so the total crop was 54 plants. Each treatment is : K0 =
without compost; K1 = TKKS compost 100 g/plant; K2 = cocoa exocarpium
compost 25 g/plant + TKKS compost 75
g/plant ; K3 = cocoa exocarpium compost 50 g/plant + TKKS compost 50 g/plant ;
K4 = cocoa exocarpium compost 750 g/plant + TKKS compost 25 g/plant ;K5 = cocoa
exocarpium compost 100 g/plant. Parameters measured were seedling height, number
of leaves, stem diameter, leaf area, root volume and seedling dry weight. Data
obtained from the research results were statistically analyzed by analysis of variance
followed by a further test of Duncan's New Multiple Range Test (DNMRT) at 5%.
Based on the research the application of cocoa exocarpium compost with TKKS
compost on the cocoa seeds that have been carried out, the result showed that
the treatment cocoa exocarpium compost with TKKS compost had significant effect
on all parameters of observation. Treatment of cocoa exocarpium compost 100
g/seed can be recommended to get the growth of cocoa’s seedling.
