【 摘 要 】

The aim of this research was to produce the oil palm empty fruit bunch (EFB) compost for ornamental plant cultivation. EFB compost was produced by chopping fresh EFB into 1-3 cm pieces, inserting the pieces into basket composter (33 cm W × 28 cm L × 40 cm H), and adding activated liquid organic fertilizer (ALOF) until moisture content (MC) in the range of 55-65%. During composting, the compost pile was turned every 3 days and the MC was maintained at 55-65% range by adding the ALOF. The compost processed was then mixed with sand and rice husk with a ratio of 1:1:1; 1:3:1; 1:0:1 and was used as a potting medium for planting some valuable ornamental plants i.e. cactus (cactaceae), sansevieria, and anthurium. Composting was carried out for 40 days and the compost characteristic were pH 9.0; MC 52.59%; WHC 76%; CN ratio 12.15; N 1.96%; P 0.58%; and K 0.95%. The compost-sand-husk rice mixture can be used as a growing medium where the best ratio for cactus, sansevieria, and anthurium was 1:3:1; 1:1:1; and 1:0:1, respectively.
