PENGARUH KOMBINASI DOSIS VERMIKOMPOS DAN MIKORIZA TERHADAP PERTUMBUHAN SEMAI FLAMBOYAN (Delonix Regia. Hook Raf) PADA TANAH ULTISOL.

Flamboyan (Delonix regia Hook Raf) is a tree species that has a very large ability to absorb carbon dioxide from the air. so it is good to be used as a city greening plant / protective plant. The research was conducted for 3 months, from January 2023 to April 2023, at the Kemiri Jaya Farmers Group in Uwemanje Village, Kinovaro District, Sigi Regency. This study used a completely randomized design (CRD) which consisted of 8 treatment combinations for each level. Each treatment combination was repeated 5 times so that there were 8x5 = 40 treatment units. The results showed that the combination treatment of vermicompost and mycorrhizal fungi had a significant effect on the growth of flamboyant seedlings, namely on the parameters of seedling height and stem toughness, but had no significant effect on stem diameter and number of petioles of flamboyant seedlings. . The treatment with vermicompost doses of 100g + 5g mycorrhizal fungi (V3M1) had a better effect on the growth of flamboyant seedlings compared to other treatments, namely an average height of 10.4 cm (V3M1), a diameter of 4.44mm (V3M1), a petiole of 8.6 strands (V3M1), and seed firmness value of 2.7.
