PEMBERIAN JENIS LIMBAH KULIT BUAH KAKAO DAN PUPUK NPK TERHADAP PERTUMBUHAN BIBIT TANAMAN KAKAO (Theobroma cacao L.)
Abstract: The purpose of this
research is determining the effect of some kinds from cocoa’s kind waste and
NPK fertilizer and to get the best dose for the growth of cocoa plantation.
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 January to April
2015. The research used Completely Randomized Design factorial that consisting
of two factors. The first factor is the cocoa’s kind waste (T) consists of four
levels, they are T1 = wet waste in chopped 100 g/plant; T2 = dry waste chopped
100 g/plant; T3 = dry waste burned 100 g/plant; T4 = compost cocoa exocarpium
waste 100 g/plant. The second factor is the NPK fertilizer (U), which consists
of 4 levels, namely U (3.75, 7.5, 11:25, 15) g/polybag. Both these factors
resulted in 16 treatsment combinations, each combination made three
replications, so that there are 48 experimental units. Each experimental unit
consisted of four plants, so the total crop was 192 plants. Parameters measured
were seedling height, number of leaves, stem diameter, leaf area, the ratio of
crown roots 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 provision of cocoa’s kind waste and
NPK fertilizer on the cocoa seeds that have been made, the result showed that
the treatment cocoa’s kind waste and NPK fertilizer had no significant on all
parameters of observation. Treatment of cocoa’s kind waste burnt 100 g/seed and
fertilizer NPK 7.5 g/seeds can be recommended to get the growth of cocoa’s
seedling.
