This study was conducted to develop an eco-friendly slow-release fertilizer by utilizing activated biochar through black carbonization of rice hull biochar and activated palm biochar. To manufacturing these fertilizers, the raw materials were ground into powder form, mixed with the binder, granulated, and then screened and dried. The best six types were selected by considering the hardness and coupling degree with activated biochar and binder. The nutrient contents of the granular fertilizer contained within the activated biochar were 30-0-13 (N-P₂O₅-K₂O, %). Results did not show a significant effect on cabbage’s leaf color, length, and width among the different treatments except for the control. However, it showed that the highest yield among the treatments was 3.5 ㎏ plant<SUP>-1</SUP> in the treatment of 5% of rice hull activated biochar. In this treatment, the yield was increased by 20% relative to that of the control. Therefore, it was decided that the optimum mixing ratio was 5% of activated rice hull biochar.
