Background : An important feature of the nutrient solution is that they affect not only the growth but also quality of crops by changing nutrient uptake, especially due to changes of EC in nutrient solution. This study was carried out to investigate effect of EC in nutrient solution on growth and ginsenoside of ginseng. Methods and Results : EC in nutrient solution was controlled with 0.68, 0.84, 1.23, 1.41 dS/m. The root weight of ginseng treated by low EC levels in nutrient solution was higher during the initial of growth. However, the higher EC levels, the more increased the change rate of root weight from the initial to the middle of growth. The highest amount of ginsenoside was changed by growth period. Although the total amount of ginsenoside in root is highest treated by EC 0.68 dS/m at 45 days after treatment. the total amount of ginsenoside in root is highest treated by EC 1.23 dS/m at 135 days after treatment. Conclusions : EC in nutrient solution should to be controlled depending on the stage of growth and the part of use, i.e. root and leaves, when ginseng is cultivated through nutri-culture.
