Background : In recent years, as the ginseng cultivation area using vinyl house is increasing, the demand of farmhouses for the studies of appropriate direct sowing cultivation and ginseng varieties for vinyl house cultivation is increasing, and there is a necessity to produce high quality clean ginseng in vinyl house in tandem with the consumers’ demand for pesticide-free ginseng. Thus, the goal of this research is to determine appropriate ridge height and width when growing ginseng in the vinyl house using direct sowing cropping system. The research was also done to choose ginseng breed for direct sowing cultivation. Methods and Results : The ground part of 4 years old ginseng grown in the vinyl house using direct-sowing cropping pattern was the type that grew well in 100 ㎝ wide ridge rather than 90 ㎝ wide ridge. It also tended to grow well in 20 ㎝ or 30 ㎝ long ridge as opposed to 10 ㎝ long ones. The root weight of the underground part was superior under 90 ㎝ × 20 ㎝(ridge height×ridge width), 90 ㎝ × 30 ㎝, 110 ㎝ × 10 ㎝ and 110 ㎝ × 20 ㎝ cultivation area. The root diameter was longer, the longer the ridge height. The volume per 1.62 ㎡ was superior for 100cm, 120 ㎝ × 10 ㎝ cultivation area. The ginseng whose ground part was superior in the vinyl house were Chungsun and Seonweon. Seonweon and Gumpoong had superior root weight in underground parts. The root length was superior for Geumsun. The ginseng that were direct sowing in the vinyl house did not have rusty ginseng problem regardless of ridge height and kind. The root injury was greatest in the cultivation area with ridge width of 90 ㎝. Conclusion : According to the results above, the growth in vinyl house using direct sowing cropping pattern was best when ridge width was 100㎝ and 110cm in ridge height of 30 ㎝. The best selection was Chunpoong and Seonweon. The root weight of the underground part was superior in 110 ㎝ × 10 ㎝ cultivation area, the best variety was Seonweon and Gumpoong.
