Oat

Oats, (Avena sativa), domesticated cereal grass (family Poaceae) grown primarily for its edible starchy grains. Oats are widely cultivated in the temperate regions of the world and are second only to rye in their ability to survive in poor soils. Although oats are used chiefly as livestock feed, some are processed for human consumption, especially as breakfast foods. The plants provide good hay and, under proper conditions, furnish excellent grazing and make good silage (stalk feed preserved by fermentation).
