Yield responses of young mature oil palms to NPK fertiliser application on loamy sand in Riau Province, Indonesia


, : Yield responses of young mature oil palms to NPK fertiliser application on loamy sand in Riau Province, Indonesia. Planter 80(944): 689-696, 699-708

A study was conducted during 1999-2003 to determine the early responses of young mature oil palms grown in Indonesia to various combinations of NPK fertilizers (N at 2.0 and 3.0 kg palm-1 year-1, P at 2.0 and 3.0 kg palm-1 year-1, and/or K at 3.0 and 4.5 kg palm-1 year-1). The soils of the trial sites were incapable of supporting high fresh fruit bunch (FFB) production without fertilizer inputs.
