Mushroom Cultivation | Class 9 Skill Education Notes

Mushroom Cultivation

Mushroom cultivation is a significant vocational skill that involves growing mushrooms for food and commercial purposes. Unlike plants, mushrooms do not grow from seeds but from spores, which germinate to form a network called mycelium. This mycelium acts like roots, spreading through the growth medium (substrate) to absorb nutrients essential for mushroom development. The substrate can be materials such as straw, sawdust, or compost, which provide the necessary nutrients. Successful mushroom cultivation requires controlled environmental conditions including proper temperature, humidity, ventilation, and hygiene. These conditions are typically recreated in moist, dark, and cool environments to mimic the natural habitat of mushrooms. The process involves several key materials and steps such as sterilisation of the substrate to remove germs and unwanted organisms, inoculation where spawn (substrate with growing mycelium) is added to a larger sterilised substrate, and incubation where the mycelium grows throughout the substrate. Maintaining hygiene during inoculation using gloves and masks is crucial to prevent contamination. Tools like pressure cookers or drums are used for sterilisation, while sprayers help maintain moisture levels. Monitoring temperature and humidity with thermometers and hygrometers ensures optimal growth conditions. Harvesting is done when mushrooms develop firm white caps, indicating readiness. This vocational skill not only provides a source of nutrition but also offers economic opportunities through small-scale farming and entrepreneurship.
