Note. Application of fertilizer in eleven months of experiment for growth analysis of oil palm seedlings. Amount of fertilizer needed for 1 replication for each level (g); TSP: triple superphosphate, MOP: muriate of potash. Level N1, P1, K1 (30%) less than N2, P2, and K2. Level N3, P3, and K3 (30%) more than N2, P2, and K2.
