Abstract


The use of liquid organic fertilizer (LOF) derived from JAKABA (Jamur Keberuntungan Abadi) has gained attention as an environmentally friendly alternative to synthetic fertilizers in leafy vegetable production. This study evaluated the effects of different LOF concentrations on the growth and biomass of kailan. The experiment was conducted using a randomized block design with six treatments, including a control, four LOF concentrations (20, 40, 60, and 80 mL L⁻¹), and a mineral fertilizer control, with three replications. Growth parameters observed included plant height, number of leaves, leaf area, fresh plant weight, fresh shoot weight, and fresh root weight. The results showed that LOF application influenced vegetative growth and biomass accumulation, with moderate concentrations (20-40 mL L⁻¹) generally producing more favorable responses compared to the control. Higher concentrations did not consistently enhance growth, indicating a non-linear dose–response relationship. Overall, JAKABA-derived LOF demonstrated potential as a sustainable nutrient input for kailan cultivation under the experimental conditions. Further studies are recommended to explore wider dose ranges, longer cultivation periods, and different soil types to refine application guidelines for practical use.
