PENGARUH PUPUK KASCING DAN PUPUK NPK TERHADAP PERTUMBUHAN BIBIT TANAMAN KAKAO (Theobroma cacao L.)
Abstract: This research aims
to determine the interaction of vermicompost and NPK fertilizers as well as get
the best dose of the growth of cocoa seedling (Theobroma cacao L.). This
research has been conducted on the experimental field of the Faculty of
Agriculture, University of Riau from April to August 2015. The study was
conducted in 4 x 4 factorial experiment arranged in completely randomized
design. The first factor is the dose of vermicompost that consists of 4 levels:
0 g/plant, 15 g/plant, 25 g/plant and 35 g/plant and the second factor is the
dose of NPK fertilizer which consisting of 4 levels: 0 g/plant, 7,5 g/plant, 15
g/plant and 22,5 g/plant. In this study, there are 16 combinations of treatment
with 3 replications so that there are 48 experimental units. Each experiment
contained 3 unit seedling and two nursery plants into samples so obtained total
144 seedlings. Observations was plant heigh, number of leaves, stem diameter,
leaf area, root volume, the ratio of crown roots and dry weight of plants. The
results showed that the interaction of vermicompost and NPK fertilizers give
the best effect at treatment of vermicompost 25 g/plant and NPK fertilizer 7,5
g/plant. Vermicompost best factor is 15 - 25 g/plant, while the factor that
best NPK fertilizer is 7,5 g/plant.
