| dc.description.abstract | The demand for pagoda mustard (Brassica rapa L.) has been increased in line with
awareness growing of healthy vegetable consumption. This study investigates the
effects of a combination of liquid organic fertilizer (LOF) derived from fermented
catfish (Clarias sp.) waste and AB Mix solution on the growth of the pagoda mustard
in a wick hydroponic system. The LOF serves as a source of organic nutrients and
beneficial microbes, while the AB Mix provides readily available macro- and
micronutrients. The experiment was arranged in a factorial Completely Randomized
Design (CRD), consisting of four levels of LOF (0, 75, 150, 225 ml/L) and three
levels of AB Mix (5, 7.5, 10 ml/L), with four replication each. Observed parameters
included the plant height, the number of leaves, the fresh and the dry weight of the
shoots and roots, the root-to-shoot ratio, and the chlorophyll content. The LOF was
prepared by fermenting 5 kg of catfish waste (Clarias sp.) with EM4, rice-washing
water, distilled water, and palm sugar for 14 days. The fermented product was
filtered and analyzed for nutrient content such as nitrogen, phosphorus, and organic
carbon. The results demonstrate that the combination of catfish waste-based LOF and
AB Mix significantly enhances the growth of pagoda mustard (p > 0.05). The best
treatment observed is P0M1 (0 ml/L LOF + 5 ml/L AB Mix), which yielded the
highest plant height, the number of leaves, the fresh plant weight, the root dry
weight, and the shoot dry weight. This study concludes the combination of catfish
waste-derived LOF and AB Mix has the potential to serve as an effective,
environmentally friendly organic fertilizer for wick hydroponic systems. | en_US |
