This research explored how shiitake mushrooms break down and use different agricultural waste materials during growth. The study found that vineyard prunings and cereal straws can effectively support mushroom growth, offering an environmentally friendly way to convert farm waste into valuable food products. Impacts on everyday life: • Provides a sustainable solution for agricultural waste management • Creates new economic opportunities for farmers through mushroom cultivation • Offers an alternative production method for nutritious and medicinal mushrooms • Demonstrates environmentally friendly recycling of farm byproducts • Could help reduce agricultural burning and associated air pollution
