Abstract
In this study, we utilised manure, fish protein fertilizer Fish Emulsion, and seaweed foliar fertilizers. The experiments were conducted from April to October 2022 with 11 treatments and three replicates. The results show that organic fertilizers significantly increase the growth, yield, and quality of Quang Tho pennywort. The treatment with 30 tons of manure and 0.5% fish protein fertilizer provided the highest economic yield (5.35 tons/ha).
