Abstract

Mushroom cultivation on common reed (Phragmites australis) substrates is a new research area. The yield distribution and nutrient changes in mushroom flushes were studied using a reed to cultivate golden oyster mushrooms (Pleurotus citrinopileatus).

The results showed that cultivating mushrooms on reed substrates resulted in different flushes of mushrooms. The biological efficiencies were found to be 69.10 % for three (FF) and 75.98 % for four (MF) flushes, respectively. Significant reductions in crude protein content (from 28.28 % to 18.35 %) were observed, while total sugar content increased from 24.86 % to 36.95 % from the first to fourth flushes under MF treatment. However, no significant differences in crude protein or total sugar were observed between FF-treated flushes. Calcium concentrations increased, while heavy metal concentrations were lower than the toxicity safety standards. In the cultivational room, inhomogeneous environmental conditions led to changes in the number of flushes, as well as altered nutrient quality and overall production when using the same substrate to cultivate the same type of mushroom.

Mushrooms are widely consumed around the world as a nutrient-dense food source with numerous health benefits. Oyster mushrooms (Pleurotus spp.) are particularly popular due to their high levels of fat-soluble vitamins and essential minerals, as well as their low sodium and fat content (Abou Fayssal et al., 2021). Oyster mushrooms are widely cultivated because they can grow on a variety of substrate materials, have a relatively short cultivation period, and a low production cost (Mahari et al., 2020a). Their growing popularity is due to their ease of cultivation, high yield potential, and medicinal and nutritional value (Chang, 2006).
