This study was performed to investigate on the combinations of optimal medium for the artificial cultivation of Pleurotus eryngii with the various kinds of substrate and nutrient. It was also tested to the mushroom yields and marketable quality of Pleurotus eryngii. Coconut ML. and bean-curd refuses were effective to the mycelial growth, which showed a similar effects compared to a standard medium. a Pine sawdust was more effective than the softened rice hulls and crude rice hulla on the mycelial growth. Elvan as additives was also showed promotive effects on the mycelial growth. In the test of medium weight, optimal weight in about 1400 ml polypropylene (PP) bottle was about 724 gram to 770 gram under 65% humidity. Most suitable periods of incubation were estimated about 40 days. It could be also considered to use TMR(Total mixed Ratio) in the medium combination as nutrients because the TMR addititon of 170 gram weight showed an excellent formation of fruiting body of Pleurotus eryngii. Finally, the optimum composition of nutrients for both yield and quality turned out to be combination of gluten feed( 21.7%), rice polishing (10.2%), wheat bran(52%), soy-hull uncrushed (13.5%) and shell lime (3.6%). Nutritional analysis of the combined nutrients was appeared to have 11.5% humidity, 15.4% crude protein, 4.5% crude fat, 12% crude fiber, 8.2% cash, 1.2% calcium, 0.94% phosphorus, and 55.4% NFE (nitrogen free extract). In the bulk test of artificial cultivation by mushroom farmer, both yield and quality were very excellent to the previous products by harvesting about 200 gram in a PP bottle without a significant deviation.
