Oats are a genus of plants in the Poaceae family, used as food and forage. Although oats did not have the importance of wheat or barley in early times, in Central Asia it was cultivated in good quantity, although it was considered a weed for those. Archaeological searches found evidence of the use of oats in Central Europe in the Bronze Age. Grains of this cereal were also found in Egyptian excavations, although it could not be proved that it was cultivated.

The genus was described by Carlos Linneo and published in Species Plantarum 1: 79–81. 1753. The type species is: Avena fatua.


Avena: generic name derived from the Latin avena = (food) and the name of the avena, Avena sativa.


It is an annual herbaceous plant, belonging to the grass family. The most cultivated species are Avena sativa and Avena byzantina, in that order.

It is rich in proteins of high biological value, fats and a large number of vitamins and minerals. It is the cereal with the highest proportion of vegetable fat, 65% unsaturated fat and 35% linoleic acid. It also contains easily absorbed carbohydrates, in addition to sodium, potassium, calcium, phosphorus, magnesium, iron, copper, zinc, vitamins B1, B2, B3, B6 and E. It also contains a good amount of fibers, which are not so important as nutrients but that contribute to good intestinal function. Oatmeal also contains small amounts of gluten, so it cannot be used as an alternative cereal for the celiac diet.

It is a plant with reticular roots, powerful and more abundant than in other cereals. Its stem is thick and straight with little resistance to overturning, its length can vary from 50 cm to one and a half meters. Its leaves are flat and elongated, with a narrow and long dark green limbus. Its flowers appear in spikes of two or three of them.

It is a plant that has less resistance to cold than barley and wheat. It is sown in early spring, to be harvested in late summer. It is demanding in water due to its high transpiration coefficient, although excess can harm it. It is very sensitive to drought, especially in the grain formation period.

Because the reticular system of oats is deeper, it can take better advantage of the nutrients in the soil, therefore it requires less fertilizers for its development.
