Root yield and quality of ginseng cultured in paddy soil was low relatively compared with that of upland soil because of moisture injury in root during rainy season. Drainage class in soils generally divided into 6 classes, and it is possible to cultivate ginseng practically in imperfectly drainage class (IDC). This study carried out to select the varieties that is suitable for paddy soil, which is easy to be generated rusty-colored root and physiological-discolored leaf. Experiment plot arranged with the condition of soil humidity contents such as poorly drainage class (PDC) and imperfectly drainage class (IDC), and upland soil. Growth characteristics and root yield were investigated in four-year-old ginseng of varieties, Cheonpoong (CP), Yeonpoong (YP), Hwangsookjong (HS), and Jakyeongjong (JK). CP among four varieties showed the highest yield in IDC and CP was the lowest ratio in leaf discoloration and rusty-colored root. HS was followed by CP in the order of root yield, but it had the weakness that the ratio of rusty-colored root was high respectively.

The quality of raw, red and white ginseng and the contents of some minerals were examined using 6-year-old ginseng roots produced in different shades, thatch and polyethylene net (P..E.). The yield of first and second grade ginseng roots was higher in the thatch shade than in the P.E. shade. The smaller sizes of ginseng routs were probably due to loss of ginseng yield called by alternaria blight in the third and fourth years, and lower quality was dale to more rusty roots in the P.E. shading. For red ginseng. rates of heaven and earth grades were higher in the P.E. than thatch shade. producing red ginseng with less inside cavity Production of white ginseng was higher in the thatch shade than in the P.E. shade. showing a higher yield, better piece grade, lower inside crack and better quality index in the thatch. The contents of some minerals such as K, Ca, Mg and Mn of fine ginseng roots differed between the two shades, some of which had a significant correlation with the quality indices of white ginseng. Keywords Thatch shade, polyethylene shade, alternaria blight, rulsty root, quality of ginseng.

금산 및 음성지역의 4년생 인삼재배 농가포장에서 직파재배 5개소와 이식재배 5개소를 임의로 선정하여 직파와 이식재배에 따른 생육특성 및 엑스와 조사포닌 함량을 비교한 결과는 다음과 같다. 직파재배는 4년근 생존율이 평균 48%로 이식재배의 86%보다 떨어지나 입모수가 평균 96주/3.3$m^2$순로 이식재배의 57주보다 많고 엽면적지수가 커 수량성이 높은 반면, 주당근중은 작았다. 직파재배는 이식재배에 비해 동체의 신장이 양호하나 지근의 발달이 불량하여 동체중의 비율이 높고 지근중의 비율이 낮았으며, 직파재배는 적변 발생율이 적으나 동체와 지근부위의 엑스와 조사포닌 함량이 낮았다.
