| Abstrak Abstract Mahogany growth is slow due to environmental soil conditions so development is supported by media or fertilizer so that quality seedlings are produced. Alternatives include adding husk charcoal as a medium and applying liquid organic fertilizer. The research aims to determine the effect of husk charcoal, liquid organic fertilizer concentration, and the interaction of media and POC on mahogany growth. Research from June to September 2023, at the Palu-Poso BPDSH Nursery, Tadulako University. using the (RAL) method. The first factor is control (P0), soil + charcoal husk 2:1 (P1), the second factor is control (C0), 15%POC (C1), 20%POC (C2), 25%POC (C3). There were eight treatments, eight replications, 64 experiments. Parameters were observed for height, diameter and leaves. research using (F test). Real treatment was obtained using 5% Test (BNT). husk charcoal as medium P1 (soil+husk charcoal 2:1) Has a significant effect on height with a value of 8.45 cm, and has no real effect on diameter and leaves. poc C3 concentration (25%) had a real influence on the growth of the highest value of 8.72 cm, diameter of 2.43 mm, and C1 (15%) number of leaves of 8.12. The interaction of husk charcoal and poc concentration had a significant effect on the increase in height, diameter and leaves. The research showed that the best increase in height and number of leaves was in the P1C3 treatment (soil+husk charcoal 2:1+25%POC) 9.31 cm and 8.63 pieces, while the best diameter was in the P1C2 treatment (soil+husk charcoal 2:1+20 %POC) 2.69 mm.
