| Abstrak Tailing soil is soil that has low NPK nutrients. Leucaena leaf compost provides nutrients needed by plants (NPK). Coconut shell charcoal is a plant growth stimulant. This study aims to determine the effect of leucaena leaf compost dosage, the effect of coconut shell charcoal and the effect of the interaction of leucaena leaf compost and coconut shell charcoal on the growth of mahogany seedlings in tailing soil. The study was conducted for three months in August-November 2024 at the BPDAS Palu Poso nursery. This study used a completely randomized design (CRD) method with a factorial pattern consisting of 2 factors, namely: the first factor is the dose of leucaena leaf compost and the second factor is coconut shell charcoal. Each treatment was repeated 7 times, so that the total used was 42 seedling units. The observation parameters were the increase in height, number of leaves, diameter and seedling strength value. The analysis of variance test (F) is used for observation parameters. If the calculated F is greater than the F table of 5%, then a further test of the Honestly Significant Difference (LSD) is carried out at a significance level of 5%. The results showed that lamtoro leaf compost had a significant effect on the increase in height and number of leaves of mahogany seedlings, while coconut shell charcoal had a significant effect on the increase in height, number of leaves, and strength value of mahogany seedlings and the interaction between lamtoro leaf compost and coconut shell charcoal had a significant effect on the increase in height, diameter, and number of leaves of mahogany seedlings. The best treatment was obtained in the combination of lamtoro leaf compost 500 gr/polybag and coconut shell charcoal 75 gr/polybag (P2A1), which gave an increase in height of 10 cm, diameter 3.14 mm, number of leaves 28.85 strands, and seedling strength 3.21. |
