This study used a completely randomized design (CRD) with a single factor, namely there were six treatment combinations of doses of inorganic fertilizers and palm oil mill effluent. 0% NPC+100% NPA = PC LCPKS (0% of fertilization dose) + Inorganic Fertilizer (100% of fertilization dose) 20% NPC+80% NPA = PC LCPKS (20% of the fertilizer dose) + Inorganic Fertilizer (80% of the fertilizer dose) 40% NPC+60% NPA= PC LCPKS (40% of the fertilizer dose) + Inorganic Fertilizer (60% of the fertilizer dose) 60% NPC+40% NPA = PC LCPKS (60% of the fertilizer dose) + Inorganic Fertilizer (40% of the fertilizer dose) 80% NPC+20% NPA = PC LCPKS (80% of the fertilizer dose) + Inorganic Fertilizer (20% of the fertilizer dose) 100% NPC+0% NPA = PC LCPKS (100% of the fertilizer dose) + Inorganic Fertilizer (0% of the fertilizer dose) Each treatment uses the same fertilizer dose, which is equivalent to 200 kg Urea ha^-1, 150 kg TSP ha^-1 and 125 kg KCl ha^-1. The conclusion of this study on the plant height parameter treatment (80% NPC + 20% NPA) is a combination of fertilizers that can match 100% inorganic fertilizers. In the dry weight parameter, treatment plants (80% NPC + 20% NPA) is a combination of fertilizers that can match 100% inorganic fertilizers.
