Abstract

This study was conducted to produce high quality ginseng seedlings by improvement of the physical properties of nursery soil. In order to select optimum nursery conditions, nursery types were treated with the yangiik nursery and semi-yangiik nursery. Soil conditioners were treated with two different materials of puffed rice husks and perlite. This experiments were tested at Gyunggido Agricultural Research and Extention Services, Hwaseng, from 2003 to 2004. Soil permeability was better at the plot of yangiik nursery than that of semi-yangjik nursery, and was better at plot of puffed rice husks than that of perlite. Soil porosity was improved 2.2% at plot of yangjiik nursery compare at that of semi-yangjik nursery, and was improved 2.0% at plot of puffed rice husks compared to control. There was no difference in the number of ginseng plants per kan among treatments. Root length was longer at plot of yangjik nursery than that of semi-yangjik nursery. More available ginseng plants per kan were obtained from the plot of yangjik nursery by more 252 seedlings than that of semi-yangjik nursery, but there was no significant difference between soil conditioners. The number of available seedlings per kan produced from yangjik nursery was 21.7% higher than those produced by semi-yangjik nursery. The number of available seedlings per kan produced from plot of puffed rice husks was 16.3% higher than that of control.
