Water dropwort(Oenanthe javanica) is grown usually in submerged paddy field and is widely used as additive in foods like Kimchi, fish soup. However, its cultivation in the under submerged cultivation has been known to cause the reduction in quality of water dropwort plants mainly due to the presence of dirt and some parasites like leeches and water animals. Thus, this study was conducted to evaluate a wetland cultivation(WLC) of water dropwort plants compared to the conventional submerged cultivation(SBC) in the greenhouse paddy field conditions. WLC and SBC treatments maintained water levels to the depth of less than 5cm and about 20cm, respectively. Vegetative stem sections were planted in September and plants were harvested in early April. The results showed that height and yield of water dropwort plants were higher in SBC than in WLC. Total yield per 10a in WLC was 12.3% lower than in SBC (2.34 vs 2.63 tons). However, the useful quality factors such as vitamin C, inorganic nutrients, chlorophyll, and anthocyanin contents were found to be considerably higher in WLC. That is Ca, K, Mg, and anthocyanin contents in the stem were increased 235%, 6%, 143% and 290%, respectively, compared to those of SBC plants. The length of underground internodes from WLC elongated about 2 times more than that of SBC, resulting in an increase in plant length and advance in harvest time. On the other hand, water dropwort plants with wetland cultivation can be produced with good cleanliness and quality, but the cultivation system should be optimized and developed to get more yield the same as SBC.
