This study was carried out investigate optimal additive content of spent medium from oyster mushroom in Volvariella volvacea cultivation. The formation of spent mushroom medium from oyster mushroom consisted of 50% pine sawdust, 30% beet pulp and 20% cotton seed hull pellet. The higher amount of spent medium from oyster mushroom resulted in higher total nitrogen content and C/N ratio of medium decreased according to increasing mixing ratio of spent medium from oyster mushroom. The fruit body yield and biological efficiency of supplemented with 50% spent medium from oyster mushroom was same level of non additive medium.
