<![CDATA[This study aimed to analyze the effect of liquid organic fertilizer (LOF) derived from goat manure and banana peels, applied either individually or in combination, on the growth and yield of pakcoy (Brassica rapa L.) cultivated under a hydroponic system as an alternative to AB mix nutrient solution. The experiment employed a Randomized Block Design (RBD) with two treatment factors: goat manure LOF concentrations (0 ml, 30 ml, and 60 ml) and banana peel LOF concentrations (0 ml, 20 ml, and 30 ml). Observed parameters included number of leaves, plant height, leaf width, root length, and fresh weight. Data were analyzed using analysis of variance (ANOVA) followed by Duncan’s Multiple Range Test at a 5% significance level. The results indicated that the best single treatment was obtained with 30 ml of banana peel LOF at 4 weeks after planting (WAP). Furthermore, the combination of 60 ml goat manure LOF and 30 ml banana peel LOF (P2K2) produced the highest and significantly different results across all observed parameters at 4 WAP, particularly in leaf number, plant height, root length, and fresh weight. Therefore, the combined application of banana peel and goat manure LOF effectively enhanced the growth and yield of hydroponic pakcoy and has the potential to serve as a more economical and environmentally friendly alternative nutrient source in hydroponic cultivation systems.]]>
