In this study, a culture with bitter gourd seedlings (Momordica charantia L.) was conducted in a field (clay slate noncalcareous alluvial soil, Tsp2), located in Wanli, Miaoli. There kinds of composted animal manure (chicken compost, cattle compost, and cattle-hog compost) as well as chemical fertilizer were applied to different treatment plots to investigate and compare their effects on soil fertility and the growth, and on the quality of bitter gourd. One check treatment was also conducted.
