The combination ratio of oyster mushroom cultivation supplements have used poplar sawdust(PS) 50% : beet pulp(BP) 30% : cotton seed(CS) 20%. we substituted cotton seed and beet pulp for dry wastes(DW) 10, 20. 30% respectively. In case of mixing DW 10% except from CS, mycelial growth was inhibited a little, but mycelial density was accelerated a little. The more DW contents increase, the more mycelial growth was inhibited, but mycelial growth was accelerated a little, respectively. In case of mixing DW except from CS, mycelial growth was inhibited a little bit. In case of mixing DW except from CS and BP, mycelial growth was inhibited remarkably. CHUNCHU variety developed resistance to DW than SUHAN variety.
