PENGARUH PERBANDINGAN TANAH DAN KOMPOS DAUN KELOR TERHADAP PERTUMBUHAN SEMAI NYATOH (PALAQUIUM OBTUSITOLIUM BURCK)

The use of soil mixed with organic matter of Moringa leaf compost with a certain dose is expected to increase the growth of nyatoh seedlings (Palaquium obtusifolium Burck). This study aims to determine the effect of the ratio of soil and Moringa leaf compost on the growth of nyatoh (Palaquium obtusifolium Burck) seedlings in the nursery.The research was carried out for three months, from March to June 2020, at the Permanent Nursery of BPDASHL Palu-Poso, Tadulako University.. This study used a completely randomized design (CRD) method which consisted of 4 treatments, namely S0 = soil without moringa leaf compost S1 = soil + moringa leaf compost (1:0,5) ; S2 = soil + moringa leaf compost (1:1); S3 = soil + moringa leaf compost (1:2). Each treatment was repeated 7 times, so there were 28 seedlings, the parameters observed were the increase of height, number of leaves, diameter, and stem sturdiness. Analysis of variance was used to determine the significant and unsignificant effect of treatment on the observation parameters, if it had a significant effects, then test of Honest Significant Difference (BNJ) was carried out at a significant level of 5%. The results showed that different composition ratios of soil and Moringa leaf compost had a significant effect on the growth of Nyatoh (Palaquium obtusifolium Burck) seedlings. The ratio of soil: Moringa leaf compost 1:2 (S3) have the best effect on all growth parameters, namely the increase in height (8.91 cm), number of leaves (4.14 sheets), and diameter (1.70 mm) compared to other treatments.Keywords: compost, moringa, nyatoh, Palaquium obtusifolium Burck, seedlin
