Abstract

The research entitled Growth Response of Oil Palm Seedlings (Elaeis guineensis Jacq.) in Early Nurseries on Peat Media. This study aims to determine the interaction effect and the main effect of POC of cow urine and urea fertilizer. This research was carried out at the Experimental Garden of the Faculty of Agriculture, Islamic University of Riau, Pekanbaru from November to February 2023. This study used a completely randomized design (CRD) in a factorial manner which consisted of two factors. The first factor was the POC concentration of cow urine which consisted of 3 treatment levels, namely: 75, 150 and 225 ml/l of water. The second factor was the dose of urea fertilizer which consisted of 5 treatment levels, namely: 0, 1.5, 3, 4.5 and 6 g/polybag. Each treatment consisted of 3 replications so that there were 45 experimental units. Parameters observed were plant height, number of fronds, length of fronds, stem diameter, root volume and root length. The data were analyzed statistically and continued with the honest significant difference test (BNJ) at the 5% level. The results showed that the interaction effect of cow urine POC and urea fertilizer was not significantly different on the parameters of plant height, number of fronds, frond length and stem diameter. The main effect of POC of cow urine was significantly different on all observation parameters with the best treatment at a concentration of 225 ml/l water. The main effect of urea fertilizer was significantly different on all observation parameters with the best treatment at a dose of 4.5 g/polybag.
