Mushroom Cultivation | Class 9 Skill Education Notes

Key steps in the process

The process of mushroom cultivation involves several systematic steps to ensure optimal growth and yield. First is the selection and site design, where mushroom varieties suitable to the local agro-climatic conditions are chosen. The growing area is designed with proper layout, often using polybags or trays placed in shaded locations with adequate ventilation and humidity control. Next is growth medium preparation, which includes testing the substrate for pH, organic carbon content, moisture, and suitability for mycelium growth. The substrate is then sterilised to eliminate contaminants. Initiating growth involves preparing spawn and inoculating it into the sterilised substrate, followed by incubation where the mycelium colonises the substrate. Management includes irrigation based on moisture tests (like the squeeze test), setting up drip irrigation or humidity containers, and troubleshooting issues such as pest infestations or gaps in sterilisation. Monitoring growth involves observing physical parameters such as mushroom height, colour, smell, and structure to detect any abnormalities. Finally, harvesting is done when mushrooms have firm white caps and visible gills, usually between flush intervals. Proper storage and packing using paper bags or refrigeration help maintain mushroom quality post-harvest.
