Summary:

Forty-five barley varieties/lines were planted in spring, and managed under rainfed conditions (Table 1). A total of 11.2 inches of rainfall was received during the growing period (April-Aug.).

On average, the barley forage yield was 6.3 t/A, and ranging from 9.6 t/A for MT19_F05_03 to 3.9 t/A for MT19_F01_02. Acid detergent fiber (ADF) averaged 33.5%, ranging from 39.3% for MT18F00309 to 27.3% for MT19_F05_03. On the other hand, MT18F00309 had the highest neutral detergent fiber (NDF) at 62.4% and MT19_F07_05 had the lowest NDF at 41% with an average at 54.3%.

Grain yield averaged 102.5 bu/A, ranging from 134.7 bu/A for Hays to 74.3 bu/A for MT19_F07_02 (Table 2). Average grain protein content was 10.3%; MT19_F06_03 had the highest protein content at 12.5% while MT19_F02_02 had the lowest protein content at 8.7%. Grain test weight (TWT) averaged 46.4 lbs/bu, ranging from 50.9 lbs/bu for Hays to 39.2 lbs/bu for MT19_F06_05. Lodging among the varieties averaged at 7.2%, while 79% of the lodging was recorded for MT19_F04_04.
