Abstract
This study aims to determine the effect of swiftlet manure bokashi on several soil chemical properties such as pH, C Organic, N, P, K, CEC and to determine the appropriate dose of swallow manure for the growth of ebony seedlings. The research was carried out for 3 months from February 2021 - April 2021 in the Palu-Poso BPDASHL Permanent Nursery located at Tadulako University, Palu city. The study was conducted using a completely randomized design (CRD) with 5 treatments and 4 replications to obtain 20 experimental units with details P0 (control), P1 (7 tons.ha-1), P2 (14 tons.ha-1), P3 (21 tons.ha-1). and P4 (28 tons.ha-1). The results showed that swallow dung bokashi fertilizer was able to improve several soil chemical properties, namely soil pH from 7,18 to 7,55 with neutral status- Phosphorus (P) from 41,34 to 65,06 with very high status, Potassium (K) from 46,26 to 53,87 with high status, C Organic from 0.53 to 1.03 with low status and N Total from 0.07 to 0,15 although in low status in soil. The application of swiftlet dung bokashi with treatment of 28 tons.ha-1 equivalent to 84.34 g per pot was the best dose for height growth and leaf number growth in ebony (Diospyros celebica Bakh) seedlings.
