Jowar, also known as sorghum, is a cereal grain that is widely cultivated in dry regions of Asia, Africa, and the Americas. It is a staple food in many parts of India and is used to make various dishes such as roti, bhakri, and dosa. Jowar grains are small, round, and white in color.
On the other hand, jau is barley, which is a cereal grain commonly grown in temperate regions of the world. It is primarily used for animal feed and malt production, but it is also consumed by humans in some cultures. Barley grains resemble wheat before peeling off, and they are larger and more elongated compared to jowar grains.
Therefore, while both jowar and jau are grains that are consumed in India, they are two different types of grains. Jowar is millet, while jau is barley.
