Peat soils have relatively low productivity due to poor nutrients, so needto pay attention to the nutrient needs of the plants. The solution needs to be donefertilization, you should use a complete fertilizer type such as NPK. Selection of NPKMutiara fertilizer because it includes inorganic fertilizer that has the advantage that is, theprovision of fertilizer can be measured and the dosage is right. The objective of thisresearch is to know how to fertilize and dose of NPK Mutiara fertilizer which givesoptimum growth on swamp jelutung plant. The expected benefits are as materialinformation and consideration of the selection of species for reforestation andrehabilitation of peatlands that want to develop the type of jelutung swamp plants.Keywords: plant growth, NPK, peat, jelutung swamp.
