(Hordeum vulgare) is commonly grown for malting but can also be grown for human food and animal feed. Barley is the main feed ingredient in some parts of western North America and in many countries in Europe that are less suitable for corn. In addition, barley can also be grown as a pasture crop and can play an important role in crop rotation in organic production systems. Barley has an extensive root system that makes it able to compete with weeds. Barley is often used to break disease, insect, and weed cycles associated with other crops. Direct rotation with other small grains, however, is not recommended.
