Effect of different grain spawn materials on Pleurotus ostreatus (Jacq.) P. Kumm. mushroom cultivation under unregulated and regulated fruiting conditions

“…The search for the best cereals grain for use in spawn production is complicated by factors related to the types of available local grains, as well as their moisture and nutritional contents, including the cultivation conditions i.e. soil and climate (Stanley & Awi-Waadu, 2010;Jiskani et al, 2007;Rosado et al, 2002;Ivanova & Kovalyshyna, 2018). In countries where there is a shortage of cereals, the use of wheat results in expensive spawn, hence they use sorghum (Sorghum bicolor (L.) Moench)) grains, cotton (Gossypium hirsutum L.) waste, and in some cases the leafy part of aquatic plants (Mahmoud, 2006).…”

“…Hence, research to find affordable and effective ingredients, as well as low-cost technology, to lower the cost of commercial spawn is intense (Gregori et al, 2008). The mixture of different materials that should increase the nitrogen content in the ready spawn, and thus improve its colonization and speed of adaptation to cultivation substrates, is an area of active research (Hoa & Wang, 2015;Ivanova & Kovalyshyna, 2018). Kananen and McDaniel (2000) patented the formula of seed mycelium with mineral components (perlite and vermiculite), which increased the number of inoculation points in 100 grams of spawn to 20 thousand pieces.…”
