Mushroom is cultivated as one of the major economical crops in many areas in Korea. The total production has steadily increased from approximately 186,400 M/T in 2007 to 190,104 M/T in 2011. This study was carried out to investigated optimum mixing ratio of Korean natural Juglans mandshurica for production of functional oyster mushroom. Mycelial growth of Pleurotus ostreatus showed the highest growth at the media of 20% Juglans mandshurica after culture of 34 days. But mushroom mycelial growth at Juglans mandshurica media was slower than that of the control. Total nitrogen and carbon source of Juglans mandshurica was 0.21% and 46.0%, respectively and C/N ratio was 219. Total nitrogen source and pH of substrates mixed with Juglans mandshurica were 2.8∼2.9 and 5.0, respectively. The contents of P2O5,, CaO, MgO and Na2O were no significant difference. The contents of Fe and Mn were decreased according to increasing of Juglans mandshurica, but the contents of Zn was increased. Yields and valid stipe number of fruiting body was the highest at 10% Juglans mandshurica, and diameter and thick of pileus were no significant difference to increase of Juglans mandshurica addition ratio. The L value of pileus was the highest at the 20% Juglans mandshurica during mushroom harvest, but there was no significant difference in the a-value and the b-value. Chemical contents of fruiting body were no significant difference.
