Substrate composition is one of the most important determinants of the growth and development of oyster mushroom.In this study, the combined effects of chemical supplements including copper sulfate (100 ug/g D.M of substrate), ammonium nitrate (150 ug/g D.M of substrate), magnesium nitrate (100 ug/g D.M of substrate) and biological supplementation of rhizobium bacteria (108 bacterium per ml for one kilogram of spawn) and also, substrates of sawdust, wheat straw, sugarcane bagasse, rice straw and olive-oil industry wastes and ratios from substrates, were studied for the cultivation of mushroom. Nitrogen of fruit body in combined substrate of wheat straw with olive pomace and the non-combined substrate of sawdust were 8.91 mg/100g D.W. and 2.6 mg/100g D.W. respectively. Also amount of riboflavin in combined substrate of sugarcane bagasse with olive pomace and the non-combined substrate of sawdust were 4.9 mg/100g D.W.. and 1.4 mg/100g D.W.. respectively. Also, spawn run-stage was completed in 16.2 days in combined substrate of wheat straw with olive-oil industry wastes. The results showed that total yield (total of three flush) of fruit body in combined substrate of wheat straw and olive-oil industry wastes that enriched with chemical supplementation of ammonium nitrate and the non-combined substrate of sawdust enriched with copper sulfate was 1862.35g and 840.90g respectively.Therefore, combined substrate of wheat straw and olive-oil industry wastes that enriched with ammonium nitrate, is a suitable substrate for the production of ostreatus mushrooms.
