In Iran, natural peat casing soil resources are limited and its harvesting has many environmental consequences. This study aimed to investigate the use of biochar in casing soil composition and its effect on the chemical properties of casing soil and the yield of mushrooms cultivated in it as a factorial in a completely randomized design with 29 treatments in 2024. Accordingly, the initial casing soil compositions including north production peat, northern production peat vermicompost, cow manure vermicompost, and spent mushroom vermicompost were prepared. Then, 5, 10, and 15 percent of biochar was added to each composition and different treatments were prepared. After preparing the casing soil, treatments usage and cultivating the mushroom. The characteristics of the pH, EC, and OM of the soil and the mushroom yield were measured. The results of this study showed that in all the studied soils, with increasing biochar, the pH, EC, and OM of the casing soil increased, and the mushroom yield had a significant positive correlation with the pH and OM of the casing soil and a significant negative correlation with the EC. The overall results showed that treatments mixed with cow manure vermicompost were superior to other treatments in terms of lower salinity and high yield. The use of biochar is importance in increasing soil organic matter, and economically, among different levels of biochar, adding 5% by weight of biochar to the soil is effective in increasing organic matter, and high organic matter in the casing soil leads to improved mushroom yield.
