Summary:

Ten varieties of winter wheat were planted on 11 October 2022 and harvested on 9 August 2023. The 10 varieties were paired with two different herbicide applied: one being conventional practice and the other with 2x the recommended rate of Beyond replicated three times.

 Amongst treated entries with 2x Beyond, the average yield was 129.3 Bu/A with SY Clearstone 2CL the highest (156.5 Bu/A) and StandClear CLP the lowest (120.2 Bu/A). Average protein was 12.4% with MTCS20158 having the highest (13.2%) and MTCS22128 along with SY Clearstone 2CL the lowest (11.6%). Average test weight was 62.8 lbs./Bu with MTCS22128 having the highest (66.3 lbs./Bu) and SY Clearstone 2CL the lowest (62.6 lbs./Bu).

Amongst the conventionally treated entries, average yield was 137.3 Bu/A with MTCS22128 being highest (153.3 Bu/A) and MTCS20156 the lowest (120.9 Bu/A). Average protein was 12.1% with MTCS20158 the highest (12.6%) and SY Clearstone 2CL the lowest (11.1%). Average test weight was 62.9 lbs./Bu with StandClear CLP the highest (63.4 lbs./Bu) and MTCS22127 (62.3 lbs./Bu).
