    This study was conducted to find out the optimum composition of nursery soil for raising seedling of ginseng(Panax ginseng C. A. Meyer). Total 9 kinds of raw materials were used such as peat-moss, perlite, leaf mould, rice bran,gull's guano, castor-oil plant bark, palm bark, cow manure and chicken manure for optimum composition of nursery soil inginseng. Occurrence of damping-off in ginseng was lowered about 50% in nursery soil type 1, 2 and 4 than in other typesnursery soil in June, and occurrence rate of rusty root also lowest in nursery soil type 1. As the salinity of nursery soilincreased, so did the occurrence of physiological disorder in ginseng seedling. The cause of salinity increasing in nursery soilhas closely relation to NO<sub>3</sub>-N, P<sub>2</sub>O<sub></sub> and Na<sup>+</sup> content. Plant height, root length, diameter and weight were longer and heavierin nursery soil type 1 (mixing ratio of peat-moss, perlite and leaf mould was 50 : 20 : 30 based in volume) than in other typesof nursery soil. So nursery soil type 1 was selected for raising seedling of ginseng. pH and electric conductivity (EC) ofselected nursery soil type 1 was 5.55 and 0.13 dS/m. Contents of NO<sub>3</sub>-N and P<sub>2</sub>O<sub></sub> were 21.0 and 40.0 ㎎/L, and K+ 0.36, Ca<sup>2+</sup>3.38, Mg<sup>2+</sup> 2.01 and Na<sup>+</sup> 0.09 cmol<sup>+</sup>/L, respectively.
