Objective:
To evaluate the agronomic performance of experimental forage barley lines grown in northwestern Montana.
Personnel:
Clint Beiermann,Jamie Sherman, Jessica Pavelka, Gregory Lutgen
Summary:
Thirty-six developmental barley lines were planted on April 29th, 2022 and harvested on August 19th, 2022 (Table 1). They were managed under rainfed conditions and received 8.1 inches of rainfall throughout the growing period (Apr-Aug).
Average yield for the study was 83.66 bu/A, with the highest yield at 103.1 bu/A for MT20_F109_08 to the lowest at 58.2 bu/A for MT20_F108_12. The highest ADF content was 40.76% for MT20_F098_01 while the lowest was 34.38% for MT20_F097_07. The average NDF content across the trial was 63.08% with MT20_F098_01 being the highest at 66.79% and MT20_F097_07 the lowest at 59.46%. The average dry matter was 90.77%, the highest at 91.16% for MT20_F098_03 and the lowest at 90.45% for MT20_F110_07.
