Pengaruh Pupuk NPK dan Pupuk Hayati Mikoriza Terhadap Pertumbuhan Bibit Kelapa Sawit (Elaeis Guineensis Jacq.) Di Main Nursery Pada Medium Tanah Ultisol
This study was conducted using a completely randomized design (CRD) factorial consisting of two factors. The first factor is NPK fertilizer consists of three levels P1 : 33 g, P2 : 40 g, P3 : 47 g per plant. The second factor is mycorrhiza biofertilizer consists of three levels M0 : control, M1 : 20 g, M2: 40 g per plant. The parameters observed were the increase in plant height, the increase in the diameter of the weevil, the increase in the number of leaves, the increase in leaf area, root volume, dry weight of seedlings and the percentage of roots infected with mycorrhiza. The Data obtained were analyzed statistically using variety analysis and the results were significantly influential followed by BNJ Test level 5 %. Application of NPK fertilizer and mycorrhiza biofertilizer affects the increase in plant height, weevil diameter, dry weight of seedlings and the percentage of roots infected with mycorrhiza. Application of compound NPK fertilizer affects the increase in plant height, weevil diameter, number of leaves, leaf area, root volume and dry weight of seedlings. Mycorrhiza biofertilizer effect on the increase in plant height, weevil diameter, number of leaves, leaf area, root volume, dry weight of seedlings and the percentage of roots infected with mycorrhiza in palm seedlings varieties D x P PPKS 540 age 3-7 months. Application of NPK fertilizer dose of 40 g per plant and mycorrhiza dose of 20 g per plant was able to increase the growth of palm seedlings in the main nursery phase of Ultisol soil.
