PENGARUH BERBAGAI JENIS DAN DOSIS PUPUK KANDANG TERHADAP PERTUMBUHAN SEMAI GAHARU (Aquilaria malaccesis Lamk)

This study aims to determine the effect of various types and doses of manure on the growth of gaharu seedlings (Aquilaria malaccensis Lamk). This research was conducted in the Permanent Nursery of the Center for Watershed Management and Protected Forests (BPDASHL) Palu Poso, Palu, Central Sulawesi. The implementation of this research was carried out for three months, from November 2021 to February 2022. This study used a completely randomized design (CRD) method with a factorial pattern consisting of two factors. The first factor is the type of manure consi sting of P1 = cow manure, P2 = chicken manure. The second factor was the dose of manure consisting of D1 = 200grams/seedling, D2 = 300grams/seedling, D3 = 400grams/seedling. Each combination was repeated 10 times for a total of 60 treatment units (seedlings). Data analysis used the F 5% test then continued with the 5% BNT test if the treatment had a significant effect. The results showed that different types and doses of manure had no significant effect on the increase in height and diameter of gaharu seedlings (Aquilaria malaccensis Lamk), but had a significant effect on the increase in leaf number of agarwood seedlings (Aquilaria malaccensis Lamk). There was no interaction between various types and doses of manure on the growth of gaharu seedlings (Aquilaria malaccensis Lamk). The effect of various types and doses of manure on the growth of gaharu seedlings (Aquilaria malaccensis Lamk) with the best diameter increase parameter (P1D3) is 16.1 mm
