Background and Objective: The problem of fertilization in Indonesia is indeed complex, especially on palm oil seedling. This study aimed to observe the effect of NPK treatment and frequency of watering to growth and proline of palm oil seedlings in pre-nursery. Materials and Methods: The experiment was done in June-September 2019. This experiment uses the RCBD Factorial method consisting of 2 treatment factors: NPK consists of 3 levels, namely, N1 = 5.0 g planting per media, N2 = 10.0 g planting per media, N3 = 15.0 g planting per media, Frequency of watering consisting of 4 levels namely L0 = 200 mL water planting per media day–1, L1 = 200 mL water planting per media days–3, L2 = 200 mL water planting per media days–5, L3 = 200 mL water planting per media days–7. The observation variables which reflect plant growth namely plant height, stem diameter, number of leaves, leaf area and one of the characteristics lack of water namely leaf proline. Results: Fertilizer NPK up to 15 g planting per media has a trend increase plant growth of palm oil seedlings in pre-nursery, frequency of watering significantly decreases plant growth, on treatment 200 mL water planting per media days–7 increases the proline content about 3.26 mM g–1. The combination of NPK fertilizer and frequency of watering has no significant effect. Conclusion: Hence it was concluded that NPK has no significant effect to the growth of seedlings, the frequency of watering which is rarely caused the growth of seedling decreased but the proline content increased in leaves.
