Farmers in Vietnam's Phung Hiep district areadopting a straw mushroom cultivation model in greenhouses, which has proven to be more productive and yield better quality mushrooms compared to traditional methods. This method allows for greater control over temperature and humidity, enabling timely harvesting and a high grade 1 mushroom yield of over 95%. It also saves space and reduces reproduction time, allowing for multiple harvests throughout the year. On average, a 100m2 area can accommodate 120-150 straw rolls, each yielding about 3kg of mushrooms, which are then sold to traders for a profit of 110,000 VND per roll, nearly double the profit from outdoor cultivation.
