The Two-rowed Barley's spike, or ear, is long and somewhat compressed, and the grain is of a very good quality. It is sown in the spring. Barley succeeds best in soils of medium consistency, but accommodates itself to almost every variety of soil, except very moist ones. It endures a drought better than excessive moistures, but it requires as deep and good tillage as wheat.

Each plant bears from one to five ears which are are cylindrical and enclosed in a covering of leaves called husks. The ears consists of grain, arranged around a pithy cylinder, called the cob.
