| Abstrak Mahogany is widely planted as a shade tree because of its heat resistance and good adaptability. Solid is solid waste from processing palm fruit into palm oil. Cow dung is a fertilizer that contains a lot of water. This research was carried out for 3 months, namely November 2021-February 2022 at the Tadulako University. The purpose of this study was to determine the effect of the dose of solid oil palm organic with addition of cow dung on the growth of mahogany seedlings in the field. The results of analysis of variance showed that the application of organic fertilizer had a significant effect. Based on the results of the significant difference of 5%, it showed that the average increase in height, diameter and number of leaves of mahogany seedlings at P3 was significantly different from treatments P4, P2, P1 and P0. The results of the average increase in height of mahogany seedlings from the highest P3 = 17.14 cm, P4 = 16.86 cm, P2 = 10.14 cm, P1 = 7.00 cm and P0 = 3.43 cm. The results of the average increase in diameter of mahogany seedlings from the highest were P4 = 1.53 mm, P3 = 1.31 mm, P2 = 0.86 mm, P1 = 0.83 mm and P0 = 0.53 mm. The average result increasing the number of leaves of mahogany seedlings from the highest was P3 = 9.43 sheet, P4 = 8.43 sheet, P2 = 6.29 sheet, P1 = 4.86 sheet.
