Binjai Km 10.8 complex T.D. Pardede at a height of ± 23 m above sea level. The study used a Randomized Block Design (RBD) consisting of two factors. The first factor is dosage of Mabar Fine Compost fertilizer: M₀ = 0 g/polybag,  M₁ = 150 g/polybag and M₂ = 300 g/polybag. The second factor is dosage of NPK fertilizer: N₀ = 0 g/plant, N₁ = 3 g/plant, N₂ = 6 g/plant, and N₃ = 9 g/plant.   The results showed that Mabar Fine Compost significantly affected plant height, leaf length, leaf width and leaf area, but had no significant effect on stem diameter and number of leaves. NPK significantly affected plant height, leaf length, leaf width, and leaf area, but no significant effect on stems diameter and number of leaves. The interaction between the two treatments had no significant effect on all observed variables.
