Abstract
This study aimed to enhance the quality of casing soil produced by the Al-Wadaq Trading Company, reduce the production costs of Agaricus bisporus, and improve energy efficiency in fruiting body production. The study involved two factors: preparation of organic and mineral supplements (C1, C2, C3) and use of different spawn inoculum levels (1%, 1.5%, 2%). The results showed that the shortest duration for complete mycelium growth and the addition of the casing layer was achieved with a 2% inoculum level, taking 18.3 and 18.2 days, respectively. The earliest fruiting body harvest occurred at 23.3 and 23.5 days with the 2% inoculum treatment combined with C2 and C3 casings, compared to 30 days for the C1 casing and 1% inoculum. The fastest batch production time of 41 days was observed with C2 and C3, and 2% spawn, whereas C1 and 1% spawn required 65 days. The highest yield was recorded with 2% and 1.5% inoculum levels combined with C3 and C2 casings, reaching 45.67, 45.17, 45.59, and 42.77 kg m-2, respectively, with biological efficiency rates of 152.2% and 151.9%. Conversely, the lowest yield and efficiency were found with the 1% inoculum and C1 casing (20.79 kg/m² and 69.3%). The number of fruiting bodies and yields from the first three harvests were significantly higher with the 2% inoculum and C2 and C3 casings
