Objective:
To evaluate the agronomic performance of experimental winter forage lines grown in northwestern Montana.
Personnel:
David Larson, Jessica Pavelka, Jessica Torrion, Jamie Sherman, Joseph Jenson
Summary:
There were 25 Forage Barley varieties planted on 26 April, 2023 and harvested on 7 September, 2023. Detailed cultural practices can be found in Table 1. It was managed under rainfall conditions receiving 5.8 inches of rain during the growing period.
Average yield was 18.1 Bu/A with MT20_F099_02 being the highest (76.5 bu/A) and Lavina the lowest (10.9 bu/A). Average dry matter production was 5.8 tons/A with MT17F02410 being the highest (7.3 tons/A) and MT20_F109_04 the lowest (4.4 tons/A). Average grain fill days was 28 days, MT16F01601 longest (35 days) and MT18F00607 the shortest (22 days). Average protein was 13.10, with MT20_F111_15 the highest average (14.51%) and MT20_F098_01 the lowest (11.91%).
