The purpose of this study was to determine the effect of various concentrations of liquid organic fertilizer from market waste on the growth and N uptake of oil palm leaves seedlings in pre-nursery. This experiment used a completely randomized design with ten replications. There were eight treatments namely 15%, 25%, 35%, 45%, 55%, 65%, chemical fertilizer (NPKMg and urea) as control and solid compost. The results showed that the application of liquid organic fertilizer at concentrations of 35% to 45% and solid compost gave the highest stem diameter and N uptake of oil palm leaves. The application of liquid organic fertilizer from a concentration of 25% to 45% and solid compost gives the highest dry weight and leaves of oil palm seedlings. Application of liquid organic fertilizer with a concentration of 45% to 65%, solid compost, or chemical fertilizer produces the highest amount of chlorophyll.
