Abstract

Abstract. Moringa leaf bokashi contains many nutrients but a low C/N ratio. Therefore, moringa leaf bokashi must be combined with another ingredient containing a high C/N ratio. This study aimed to obtain the appropriate proportion of moringa leaves and empty oil palm fruit bunches for making good bokashi according to standard organic fertilizers and their application dosage to okra plants. The experiment of the combination of moringa leaf and empty palm oil fruit bunches (1:1, 1:2, and 1:3) and the application dosage to okra plants (10, 15, 20, and 25 tons ha-1) were arranged according to a completely randomized design with three replication. The results showed that single moringa leaf bokashi with a C/N ratio of 2.8 became 6-7.5 in bokashi made from a combination of moringa leaves and empty oil palm fruit bunches. Bokashi, made from moringa leaves mixed with empty palm oil fruit bunches in a ratio of 1:1, has a crumb texture and is black. Bokashi, with a ratio of 1:2 and 1:3, has a slight crumb texture and blackish-brown color. Only the number of leaves was affected by the ratio of moringa leaves and empty palm oil bunches and the application dose. The composition of moringa leaves and empty oil palm fruit bunches and the application dosage did not significantly affect the growth and yield of okra plants. However, the growth and yield of okra plants tended to be better at a 1:2 ratios of 10 tons-1 application dose.
