Agaricus bisporus edible mushroom is the most abundant industrially cultivated mushroom and due to appropriate nutritional quality and high amount of protein has special place in world’s population food basket. The use of organic wastes in edible mushroom producing could be suitable solution to removal of these wastes and supply the world’s population food. In this research, in order to survey the practicability for use of different organic wastes as button mushroom culturing substrate and effect of plant growth promoting bacteria on yield and quality of edible mushroom an experiment was conducted as factorial arrangement with two factor and in three replications. First factor consisted of four substrate including fresh mushroom compost, spent mushroom compost, municipal solid compost and vermicompost, which mixed with fresh mushroom compost at the ratio of 1:1. Second factor include no-bacteria, and two IAA producing bacteria treatments, including Pseudomonas fluorescens and Rhizobium leguminosarum biovar phaseoli. Results showed that the effect of different substrates had a significant difference on mushroom yield (P<0.01) and fresh mushroom compost with the mean value of 545.5 gr, has allocated the most amount of yield, also in vermicompost bed mushroom was not produced. Among the inoculated bacteria, Rhizobia bacteria caused improving in mushroom yield at all substrates and has increased 17.2 percent mushroom yield compared to non-bacterium treatment. Mushrooms protein is also affected under the tow factor of bed and bacteria and the most protein percent was observed in municipal solid waste treatment in companying with Pseudomonas fluorescens.
