Objective:
To evaluate the agronomic performance of hulless barley varieties grown in northwestern Montana.
Personnel:
Clint Beiermann,Jamie Sherman, Jessica Pavelka
Summary:
Sixteen hulless barley lines were planted on April 28, 2021 and harvested on August 30, 2021 (Table 1). They were managed under rainfed conditions, and received 7.8” of rainfall throughout the growing period.
Average yield for the study was 109.4 bu/A, with the highest yield at 135.6 bu/A for Havener to the lowest at 86.0 bu/A for MT18H01901. The highest protein content was 14.3% for MT18H03101 while the lowest was 10.9% for Havener. The average protein content across the trial was 12.9%. Six lines showed significant lodging at 23% or greater, and included: MT18H02801, MT19_H11_07, MT19_H14_05, MT19_H11_04, MT19_H14_10, and MT18H03101. Average test weight of all lines was 53.9 lb/bu. The highest test weight was MT18H02901 at 58.4 lb/bu and the lowest was MT19_H11_07 at 49.8 lb/bu. The average height was 82 cm, with the tallest variety at 91.4 cm for MT19_H11_04 and the shortest at 67.8 cm for MT19_H08_15 (Table 2).
