Respon Pertumbuhan Bibit Kelapa Sawit (Elaeis Guineensis Jacq.) Terhadap Pemberian Mikoriza Dan Pupuk Rock Phosphate Pada Medium Ultisol Di Main Nursery
ABSTRACT
Oil palm (Elaeis guineensis Jacq.) is an important plantation crop in Indonesia, because of its high economic value and one of the leading plantation commodities in Riau which is used as a source of vegetable oil. This study aims to evaluate the interaction effect between mycorrhiza and Rock Phosphate fertilizer, single factor of mycorrhiza and Rock Phosphate fertilizer, and get the most effective combination of mycorrhiza and Rock Phosphate fertilizer doses on the growth of oil palm seedlings (Elaeis guineensis Jacq.) on Ultisol medium in the main nursery. This research was conducted at the oil palm nursery in Jalan Garuda Sakti KM 7, Karya Indah Village, Tapung District, Kampar Regency, Riau Province. The study used a 3 × 3 factorial experimental method arranged in a completely randomized design (CRD). There are two factors, namely: The first factor is the dose of mycorrhiza (M) which consists of three levels: M0 = without mycorrhiza (control), M1 = 10 g for each plant, M2 = 20 g for each plant. The second factor is the dose of Rock Phosphate fertilizer (R) which consists of three levels: R1 = 10 g for each plant, R2 = 20 g for each plant, and R3 = 30 g for each plant. The results showed an interaction between mycorrhiza and Rock Phosphate fertilizer on the number of leaves, stump diameter, root volume, seedling dry weight, and percentage of mycorrhiza-infected roots. Application of mycorrhiza at a dose of 20 g for each plant gave the best growth results of oil palm seedlings in the main nursery.
