EFEKTIVITAS PUPUK MAJEMUK DAN Cu TERHADAP PERTUMBUHAN VEGETATIF TANAMAN KELAPA SAWIT (Elaeis guineensis Jacq.) DI LAHAN GAMBUT
Abstract: This studyaims to
determine the effective eness of compound fertilizer and Cuon the vegetative
growth of oil palm (Elaeisguineensis Jacq.) inpeat land.This research has been
carried out in village Rantau Bais ,sub-district Tanah Putih, Rokan Hilir
regency from March to July 2014. This study used arandomized block design (RBD)
factorial consisting of two factors. First factoris thedoses of compound
fertilizer NPK (M),consists of 4 levels is: without NPK fertilizer, 400g/plant
NPKfertilizer application, 600g/plant NPK fertilizer as and 800g/plant NPK
fertilizer. Second factoris thedoses of Cu(C)fertilizerin4levels is: withoutCu
fertilizer application, 25g/plant Cufertilizer application, 50g/plant
fertilizer application and 75g/plant Cufertilizer aplication. Parameter
observed was the increase in plant height, number of fronds, added girth and
length fronds. Data were analyzed statistically using ANOVA followed by
Duncan’s test at the 5% level. The results showed that the best interaction
demonstrated by NPK compound fertilizers of 800 g/plant and fertilizer Cu of 75
g/plant was effective in increasing the length of the stem but not effective in
increasing plant height, number of fronds and increase girth. The NPK compound
fertilizers are not effectivelyall parameters. Copper fertilizer of 75 g/plant
was effective in increasing the length of the stem, but not effectively for
other parameters.
