Abstract

The research was carried out in Sitmarkho village – Latakia, within a sealed room, during April – June 2023; For study the effect of 3 factors on the amount of Oyster mushroom production and its protein content .Factorial experiment method was used including three factors: (two mushroom strains Gosm and Florida, two sterilization liquids: water, and olive mill water, and three substrates: (Wheat straw, sawdust, and their mixture equally), using the completely randomized design, which  included twelve combinatorial treatments, each one with three replicates. GenStat-12 program was used with Duncan-LSR parameters at 1% level. Results showed Florida strain was significantly superior on production quantity (500.1g/1kg wet weight) to the Gosm strain (386.1)g, while the Gosm strain was significantly superior to the Florida strain in protein content of wet weight (3.40, 3.22)% respectively. Sterilization with water also outperformed sterilization with Olive mill water in producing (473.1, 413.1 g/1 kg dry weight), respectively, while sterilization with the Olive mill water was superior in protein content (3.392, 2.231%), respectively. The Wheat straw substrate outperformed the rest substrates significantly in production trait, while the sawdust was superior in protein content%. The combinatorial treatments varied significantly; the treatment T4: (Wheat straw + water sterilization + Florida strain) outperformed all treatments in the production (923.3) g/1 kg. While the treatment (T8: sawdust + Olive mill water sterilization + Gosm strain) outperformed all treatments in Protein content (3.670%) of wet weight.

Keywords: Oyster mushrooms, Olive mill water, production, protein.
