Most of common bean is capable to be produced in Malaysia but production of common bean in our country is insufficient to meet with local market demand. In conventional farming, farmers typically applied 10,000 kg / ha of compost during preparation of bed. So, this research were trying to decrease the amount of compost used by investigating the best dosage of bokashi application. The objective of this research was to assess the growth performance and yield of common bean when different amounts of bokashi are applied.
Randomized Block Design (RBD) with three replicates for each treatment were used in this research. There were six treatments of different amounts of bokashi which is 0kg/ha
(as negative control), 2000kg/ha, 4000kg/ha, 6000kg/ha, 8000kg/ha of bokashi and 10000kg/ha of compost as the positive control. There are 9 parameters were taken for analysis such as plant height, number of leaves, number of branches, number of flowers per plant, numbers of flowers per plot, number of pod per plant, number of pod per plot, yield per plant and yield per plot. The results showed that the treatment that has high growth production was treatment 5 that contained 8000kg/ha bokashi and the treatment that produced high number of yield was treatment 2 that contained 2000kg/ha bokashi.
