Irrigation of small grains in Arizona
Wheat and barley use about 2 ft of water in Arizona, but 3 to 3.5 ft of applied water is often required with surface flood irrigation due inefficiencies in the irrigation system. Less irrigation water is required with more efficient irrigation systems such as sprinkler or drip. If 6 inches of water is applied per irrigation, then six or seven irrigations are required during the season. The first post-emergence irrigation is generally needed by the 5 leaf stage and the last irrigation by soft dough.
