Pakcoy (Brassica rapa L.) is a leafy vegetable whose growth and yield depend strongly on nutrient availability. Declining soil fertility and low organic matter can constrain nutrient availability and crop productivity, particularly in intensively cultivated horticultural land. Golden apple snail (Pomacea canaliculata) is locally abundant and contains protein and amino acids that can be processed into liquid organic fertilizer (LOF). This study aimed to evaluate the response of pakcoy to different concentrations of amino-acid-based golden apple snail LOF and to identify the concentration producing the best growth and yield under the experimental conditions. The experiment was conducted from March to May 2026 in Binaka Village, Gunungsitoli Idanoi District, using a non-factorial Randomized Complete Block Design with five treatments (0, 20, 40, 60, and 80 mL/L) and five replications, for 25 experimental units. Data were analyzed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT) at the 5% level when significant. The 80 mL/L treatment produced the highest values at 4 weeks after transplanting, namely plant height of 29.04 cm, 18.00 leaves plant?1, and fresh weight of 348.80 g plant?1. Relative to the control, these values represented increases of 44.05%, 100.00%, and 316.23%, respectively. The results indicate that 80 mL/L was the best concentration among the concentrations tested. However, the optimum concentration beyond 80 mL/L and the physiological and biochemical mechanisms underlying the response require further study.
