Summary:

Twenty-four barley varieties/lines were planted in the spring of 2021 and managed under rain fed conditions (Table 1). A total of 8.9 inches of rainfall was received during the growing period (April-Aug).

Forage biomass yields averaged 4.1 tons/A, and the highest yielding variety was Lavina at 7.4 tons/A and the lowest yielding was MT19_F04_03 at 3.3 tons/A. On average the harvested grain yield was 92.1 bu/A. Grain yields ranged from 105.7 bu/A for MT17F02406 to 58.4 bu/A for MT18F01104. Plant heights averaged 79.4 cm, with the tallest variety being MT18F01104 at 93.3 cm to the shortest variety MT19_F03_05 at 67.8 cm. The average test weight was 43.7 lb/bu (Table 2).
