Durable agricultural products are systematically classified based on their botanical characteristics and nutritional profiles:

  • Cereals: Small, hard, dried seed-fruits belonging to the grass family (Poaceae), where the fruit wall and seed wall are naturally united. They are utilized for human consumption and livestock feed. Key examples include maize, millet, rice, sorghum, and wheat.
