Proper storage of harvested grains is crucial to prevent spoilage, pest infestation, and moisture damage, which can lead to significant post-harvest losses and impact food security. Measures to protect stored grains include: 1) Drying: Ensuring grains are thoroughly dried to reduce moisture content and prevent mold growth. 2) Pest control: Using fumigation, pesticides, or biological methods to keep insects and rodents away. 3) Proper containers: Storing grains in airtight, moisture-proof silos, granaries, or jute bags to prevent contamination and humidity. 4) Ventilation: Ensuring adequate air circulation in storage facilities. 5) Hygiene: Regularly cleaning storage areas.
