Relationships Between Growth Characteristics as well as Mineral Consents of Ginseng Seedlings and Yield of Ginseng Roots

묘삼의 생육특성 및 무기성분과 인삼생산과의 관계

This study was conducted to investigate the effects of growth characteristics and mineral contents of ginseng seedling grown in different locations on ginseng growth and root yield. Ginseng seedling produced in 16 farmers' field at the semi-Yangjik seedbed were planted and cultivated in a field with same cultural practices. Missing plant was increased with increased year of ginseng age, especially severe at 5-year-old ginseng. Rate of missing plant was different among the origins of the seedling, even with the same weights. Negative correlation was noted between the missing rate of 3-year-old ginseng plants and NH4-N content of the seedling, but positive correlation between the missing rate and K2O and Ca contents of the seedling. Root yield of 6-year-old ginseng was also affected by the origins of ginseng seedlings. Root yield was high in ginseng plant from 0.6∼0.9 g see dings compared to those from over 0.9 g seedlings.
