Several agricultural substrates, including barley straw, corn cobs, corn stalks and leaves, weeds, and recycled paper, were evaluated to determine their potential for Pleurotus ostreatus production by analyzing their physicochemical composition and efficiency in fungal growth. Corn cobs, with 35% cellulose and only 4% lignin, achieved the highest biological efficiency at 85% and enabled harvesting in 19 days, outperforming other substrates in productivity and speed. Barley straw, with a higher lignin content (7%), showed limitations, achieving a biological efficiency of 65% and extending the time to harvest to 26 days. The analyses indicated that protein content in fruiting bodies varied depending on the substrate, reaching 26% in corn cobs compared to 21% in barley straw, suggesting that the initial composition of the substrate influences the mushroom’s nutritional value. The potential of certain agricultural residues as efficient and sustainable substrates for P. ostreatus cultivation is demonstrated by their contribution to a viable alternative for waste valorization and circular economy in agriculture.
