Barley
Barley is a cereal crop (crops that are classified as grass or crops that belong to the grass family and are grown for their seeds) and it is the fourth most grown cereal crop in the world. Other cereal crops include rice, wheat, corn, millet, sorghum, oat and rye. The barley seed looks somewhat like wheat but it has a longer beard (the bristles that protect the kernel) and it is best described, like many of the other cereal crop seeds, as small, white and longish. Barley originated or was first grown as a crop, in the Fertile Crescent (an area incorporating Mesopotamia and the Levant) and was domesticated approximately 10,000 years ago. It is the oldest domesticated cereal crop in the world. Barley was initially used to make bread and porridge and later became a commodity that was bartered and traded. It was more popular in West Asia and North Africa than in Europe where it was generically referred to as corn which in ancient times also included other cereal crops like rice
