Objective:
To evaluate the performance of selected barley varieties in northwestern Montana
Personnel:
Clint Beiermann,Jamie Sherman, Jessica Pavelka, Gregory Lutgen
Summary:
Twenty-five barley varieties were planted on April 28th, 2021 and managed under rainfed conditions (Table 1). A total of 8.9 inches of rainfall was received throughout their growing period (April-Aug).
Average forage biomass yield was 4.1 tons/A, with the highest yield being 4.73 tons/A for Lavina, to 3.31 tons/A for MT19_F04_03. Average 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. Test weight averaged 43.7 lb/bu for all varieties, ranging from 46.5 lb/bu for MT16F02408 to 40.4 lb/bu for MT19_F07_04. Average plant height was 79.4 cm, ranging from the tallest variety MT18F01104 at 93.3 cm to MT19_F03_05. At 67.8 cm (Table 2).
