Abstract
Fertilisation is crucial to sustaining optimum vegetative growth and yield performance of oil palm in high-density planting (HDP). In this study, the fresh fruit bunch yield was significantly improved by increasing the application of nitrogen up to 6 kg of ammonium sulphate palm-1 year-1. Nonetheless, the yield performance was less responsive to potassium fertiliser mainly due to the high potassium reserve in the coastal clay soil of Peninsula Malaysia. No significant interaction effects were observed between nitrogen and potassium on the yield performance. Conclusively, considering the palm vegetative growth, FFB yield, and economic benefits, the optimum N and K rates for high-density planting in oil palm under the coastal environment of Peninsula Malaysia were 4 kg of ammonium sulphate palm-1 year-1 and 1 kg of muriate of potash palm-1 year-1 respectively
