Objective:       

To evaluate the agronomic performance of barley varieties grown in environments representative of northwestern Montana.    

Results:           

Twenty-four barley varieties were evaluated for yield and agronomic performance using a randomized complete block design with three replications. Significant differences were observed for heading, height, test weight, and percent plump, but no significant differences were observed for yield and protein (Table 2).  Heading date averaged 176 Julian days (June 24) and ranged from 169 days for Conlon to 179 days for Merit, MT100126, and Moravian115.  Heights averaged 27.8 inches and ranged from 19.4 inches for Stockford to 31.2 inches for Stepford.  Yields averaged 86.6 bushels per acre. Protein averaged 9.57 percent.  Average test weight was 52.6 lb/bu and ranged from 47.4 lb/bu for Stepford to 54.4 lb/bu for Champion.  Percent plump averaged 96.9 %, and ranged from 89.0 % for Lavina to 99.2 % for Conlon.

Summary:       

The highest yielding commercially available cultivars in this study were Hockett, Merit, and Synergy; however, their differences were not statistically significant.
