Abstract

This study aims to determine the interaction effect and the main effect of palm oil effluent and Phonska NPK fertilizer on the growth of oil palm seedlings in the pre-nursery. This research was conducted at the Experimental Garden of the Faculty of Agriculture, Islamic University of Riau, Jalan Kaharuddin Nasution No. 113, Air Cold Village, Bukit Raya District, Pekanbaru City. The study was carried out for 4 months starting from September to December 2021. This study used a Factorial Completely Randomized Design (CRD) consisting of two factors. The first factor is the provision of palm oil liquid waste consisting of 4 levels, namely: 0, 0.75, 1.5, 2.25 l/seed and the second factor is NPK Phonska which consists of 4 levels, namely: 0, 15, 30, 45 g/seed. Parameters observed were plant height, number of midrib per plant, stem girth, dry weight and root volume. The data were statistically analyzed and presented with the Honest Significant Difference Test (BNJ) at the 5% level. The results of the study concluded that the interaction of palm oil effluent and Phonska NPK had an effect on plant height, stem girth, wet weight and root volume of oil palm seedlings. The best treatment was a combination of palm oil effluent treatment of 2.25 l/seed and NPK Phonska 45 g/seed. The main effect of palm oil effluent has a significant effect on all observation parameters, the best treatment is the dose of 2.25 l/seed. The main effect of Phonska NPK significantly affected all observation parameters, the best treatment was a dose of 45 g/seedling.
