Abstract: In this study, we aimed to determine the best agricultural waste media mixtures for Ganoderma carnosum Pat. cultivation, which is almost unknown in Turkey. Six different growing mixtures were prepared using oak sawdust, peanut shell, and corn cob: C (oak sawdust), M1 (2 oak sawdust + 1 wheat bran), M2 (2 peanut shells + 1 wheat bran), M3 (1 oak sawdust + 1 peanut shell + 1 wheat bran), M4 (2 corn cobs + 1 wheat bran), M5 (1 oak sawdust + 1 corn cob + 1 wheat bran). During the study, mycelial growth time, biological efficiency (BE), mushroom weight, total yield, cap diameter, cap thickness, dry matter of mushroom samples, and pH and moisture content of the mixtures were determined at different periods (after sterilization, after mycelia development, and after harvest). Mycelial development time was detected between 26.00 and 41.00 days. The highest and the lowest yield values were obtained from M2 (53.90 g kg^-1) and C (14.63 g kg^-11), respectively. The highest amount of dry matter was recorded in C (20.29%) while the lowest amount was obtained from M2 (17.97%). It has been determined that the average weight of the mushrooms varied between 6.46 and 23.00 g. The pH was the highest after sterilization (5.62) and the lowest after harvest (4.21) periods. In terms of moisture content, the highest content was observed after harvest period as 66.17%. When the results were evaluated based on yield and biological efficiency, which are the most important criteria for producers, the use of oak sawdust alone or in combination seems to be disadvantageous.
