Abstract
Commercial hybrid grain sorghums were evaluated at the Marana Agricultural Center from 1983 to 1985 to furnish local growers with information on currently available hybrids. (See 1984, 1985, and 1986 Forage and Grain Reports for details). Sorghum was grown under three conditions each year: 1) full season with optimum irrigation and minimal water stress; 2) full season with limited irrigation and medium water stress; and 3) short season with one irrigation for emergence planted in early July after barley or wheat harvest to simulate double -crop conditions. Seed was received from nearly 20 seed companies and the number of entries in each test ranged from 64 to 96.
