UJI PENGGUNAAN KOMPOS KULIT BUAH KAKAO DAN PUPUK NPK TERHADAP PERTUMBUHAN BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.) ASAL KECAMBAH KEMBAR PADA MEDIUM SUBSOIL ULTISOL
Abstract: The purpose of this
study the interaction KKBK with NPK and determined the best treatment for
growing of twin sprouts oil palm seedlings
(Elaeis guineensis Jacq.) in the subsoil ultisol medium. Research
conducted at the Laboratory of Plant Experimental Farm, Faculty of Agriculture,
University of Riau, Pekanbaru. The study was conducted four months from
February to May 2016, carried out with completely randomized design (CRD)
factorial comprises two factors and 3 replications. KKBK first factor (K)
comprises 4 levels : K0 = without KKBK, K1 = KKBK 12.5 tonnes/ha or 50 g/plant,
K2 = KKBK 25 tonnes/ha or 100 g/plant, K3 = 37.5 tonnes KKBK/ha or 150 g/plant.
The second factor NPK (P) comprises 4 levels : P0 = ¼ dose of 0.1125 tonnes/ha
or 6.25 g/plant, P1 = ½ dose of 0.225 tonnes/ha or 12.5 g/plant, P2 = ¾ doses
of 0.3375 tonnes/ha or 18.75 g/plant, P3 = 1 dose of 0.45 tonnes/ha or 25
g/plant. Each unit contains 2 plant samples. The parameters those observed were
plant height, leaf number, stump diameter, root volume, seedlings fresh weight
,seedling dry weight, fresh and dry
weight of shoot and roots. Data were
analyzed with analysis of variance
and Honestly Significant Difference
(HSD) of 5%. The results showed interaction of KKBK 150 g/plant and NPK 25
g/plant in the nursery generate the highest of all the parameters compared to
other treatments.
