Abstract

The purpose of this study was to determine the growth response of oil palm seedlings (Elaeis guineensis Jacq) in main-nursery to the interaction of banana stem bokashi doses and NPK pearl fertilizer 16:16:16. This research was carried out in the experimental garden of the Faculty of Agriculture, Riau Islamic University, Pekanbaru City for 5 months starting September 2021 – January 2022. The design used in this study was a factorial Completely Randomized Design (CRD) consisting of two factors. The first factor was banana stem bokashi fertilizer (B) consisting of 4 ie without bokashi, 800, 1,600, 2,400 g/plant. The second factor was pearl NPK 16:16:16 consisting of 4 levels, namely without NPK, 11.25, 22.50, 33.75 g/plant, 16 treatment combinations were obtained with 3 replications, so there were 48 experimental units. Parameters observed were increase in plant height, increase in the number of fronds, increase in the length of the longest frond, increase in stem circumference, root length and root volume. Data were analyzed statistically and continued with BNJ level of 5%. The results showed that the interaction of banana stem bokashi fertilizer and pearl NPK 16:16:16 gave a real response to all parameters. Best response to bokashi fertilizer 2,400 g/plant and pearl NPK 16:16:16 33.75 g/plant. Keywords: Bokashi Banana Stems, NPK Mutiara 16:16:16, Oil Palm
