PENGARUH KOMBINASI KOMPOS TANDAN KOSONG KELAPA SAWIT DENGAN PUPUK NPK PADA MEDIUM PODZOLIK MERAH KUNING TERHADAP PERTUMBUHAN BIBIT KAKAO (Theobroma cacao L.)
Abstract: The aim of this
research is to identifity the effects and to get the best dosage of TKKS compost combination with
NPK fertilizer in red-yelow podzolic medium for cocoa seeds growth varieties
forestero the age of 4 months. This research was conducted at the experimental
garden of Agriculture Faculty, University of Riau, Bina Widya street KM 12,5
Pekanbaru. This research arranged experimentally using Completely Randomized
Design (CRD), with some treatment dosage combination of TKKS compost with NPK
fertilizer (P) consist of: P1=37.5 g Compost + NPK 7.5 g, P2= 37,5 g Compost +
NPK 11.25 g, P3= 37,5 g Compost + NPK 15 g, P4= 75 g Compost + NPK 7.5 g, P5=
75 g Compost + NPK 11.25 g, P6= 75 g Compost + NPK15 g and consist of 3
replication. Data were analyzed statistically using variety of analysis and
further test followed by Duncant’s test at 5 % level. Parameters observed were
the seeds height, number of leaves, stem diameter, leaves widht, root width
ratio, dry seeds weight, NPK fertilizer efficiency and it relation with dry
seeds weight. The result show by giving some treatment of TKKS compost
combination with NPK fertilizer on medium podzolic red-yellow on cocoa seeds
growth varieties forestero the age of 4 months not reveal significantly to all
observed. Giving P1 tretment tend to produce better growth of cocoa seeds. It
is seen from seeds height, stem diameter
and dry seeds weight. Giving P3 treatment gave the largest efficiency of using
NPK fertilizer to 46.113%.
