Abstract

This research was conducted at the Palm Oil Nursery, Jl. Lintas Timur KM 12, Hamlet I, Baru Village, Siak Hulu Subdistrict, Kampar Regency, from March - July 2019. The purpose of the study was to determine the interaction and main effects of NPK 15:15:15 fertilizer and mycorrhizal biological fertilizer on oil palm nurseries in Main Nursery. This research uses a Factorial Complete Randomized Design. The first factor is NPK 15:15:15 (N) fertilizer consisting of 4 levels, 0, 75, 150 and 225 g / plant and mycorrhizal (M) biological fertilizer consisting of 4 levels, 0, 20, 40 and 60 g /plant. There were 16 combinations of treatments and 3 replications. The parameters observed were plant height (cm), increase in the number of fronds (strands), increase in length of the longest stem (cm), girth of the stem (cm), root volume (cm3) and longest root length (cm). Observational data were analyzed statistically and continued with BNJ further tests at the 5% level. The results showed the interaction of NPK 15:15:15 and mycorrhizal biofertilizers had a significant influence on the addition of the longest midrib stem length (cm). The best combination of treatment at a dose of NPK 15:15:15 225 g / plant and 40 g mycorrhizal biological fertilizer (N3M2). The main effect of NPK fertilizer 15:15:15 and mycorrhizal biofertilizers have a real influence on all parameters observed. The best treatment is the dosage of NPK 15:15:15 225 g / plant (N3) and the dose of mycorrhizal biological fertilizer 40 g / plant (M2).
