Summary:

Forage barley varieties were seeded on April 29th, 2022 and harvest on August 17th, 2022 (Table 1). They were managed under rainfed conditions with a total of 8.1 inches of rainfall received during the growing period (April-Aug).

The highest yielding variety was MT17F02410 with an average yield of 110.2 bu/A. The lowest yielding variety was MT19_F01_03 with an average yield of 74.3 bu/A. The overall yield average was 88.08 bu/A. The average forage dry matter was 28.56% and ranged from 30.8% for MT19_F04_01 to 27% for MT18F00812. The average ADF was 37.65% and ranged from 39.9% for Haymaker to 35% for MT19_F04_02. The average NDF was 62.0%, with the highest being 65.6% for Haymaker and the lowest at 58.8% for MT19_F04_02.
