Abstract:

Agaricus blazei is considered a medicinal mushroom and is produced mainly in Brazil and China. Several compost formulations and techniques that are usually adaptations of A. bisporus cultivation may be used for commercial production of A. blazei. However, inconsistent yields, undefined flushes and long production cycles occur very often. Compost supplementation for Agaricus sp. is used to improve yields and quality of mushrooms along different flushes. In contrast, in A. blazei cultivation, the benefits of supplementation are questionable. It has been observed that yields are still inconsistent and contamination occurs frequently. In addition, some supplements may not be cost-effective for farms. We investigated the effect of two supplements (soybean meal and ChampFood mushroom supplement) added in compost at two phases (at spawning and colonisation of compost). The results obtained from this research indicated that the highest yields can be reached when using soybean meal (9.65%) at spawning and ChampFood (9.31%) before casing. The supplements did not affect the duration of flushes.
