This study was carried out to investigated mixing ratio of redginseng marc using organic waste resource for production cost-reduction of oyster mushroom. Redginseng marc were examined as substitute of cottonseed meal which was primary nutritive material of mushroom growing substrate. Total nitrogen and carbon source of redginseng marc was 45% and 2.7%, respectively and C/N ratio was 16.7. Total nitrogen source and pH of substrate mixed with redginseng marc was 4.6~4.9 and 2.5~2.8, respectively. The contents of $P_2O_5$, $K_2O$ and MgO were decreased by increasing redginseng marc, but increased at the 20% redginseng marc. The contents of CaO was increased by increasing redginseng marc, but there was no significant difference in $Na_2O$ content. The more mixing ratio of redginseng marc was increased in column test, the more mycelial growth growed slowly. Yields of fruiting body was no significant difference compared with control group by adding of 10~50% redsingeng marc instead of cottonseed meal, but decreased sharply at only 20% redsingeng marc without cottonseed meal. The L value of pileus by increasing redginseng marc decreased during mushroom harvest, but there was no significant difference in the a-value and the b-value.
