Response of oil palm seedlings to combined application of NPKMg 12: 12:17: 2 and liquid fertilizers (humikon and metalon) was studied in the main nursery of the Nigerian Institute for Oil Palm Research (NIFOR) for two cropping seasons. The trial consisted of 8 treatments laid down in Randomized Complete Block Design (RCBD) in three replicates. Treatments were Zero application (control), 28g NPKMg + 15g metalon, 28g NPKMg + 15g humikon, 42g NPKMg + 30g humikon, 42g NPKMg + 30g metalon, 28g NPKMg only and 42g NPKMg only. Treatments were applied at 3, 5 and 8 months after planting and data were collected on seedling height, girth, leaf number, leaf area, dry matter yield and percentage of transplantable seedlings at 3, 6, and 12 months after planting. Data collected were analysed using analysis of variance and their mean compared with Turkey’s Honest Significance Difference (THSD) at 5 % level of probability. At 3 and 6 months after planting seedling height, girth, leaf number and leaf area were not significantly affected by the treatment. However, at 9 and 12 months after planting the palm height, girth, leaf number, leaf area, dry matter yield and the number of transplantable seedlings were significantly affected by the treatments. The highest palm height (118.5 cm), girth (27.0 cm), leaf number (14), transplantable percentage (95.7 %) and dry matter yield (195.7 g) were obtained in seedlings that received combined application of 28g NPKMg 12: 12:17 : 2 and 15ml metalon, while the least palm height, girth, number of leaf, leaf area, transplantable percentage and dry matter yield were obtained from the control.
