Objective:

To evaluate the performance of selected spring wheat varieties in a production environment in northwestern Montana

Summary

The off-station spring wheat trial was planted on April 22, 2019 under dryland conditions. See Table 1 for detailed management information.

Yields ranged from 62.5 bu/A (LIMAGR143) to 42.1 bu/A (AGRIPR10), with an overall average of 54.3 bu/A (Table 2).  Average test weight was 61.8 lb/bu.  MT1673 had the lowest test weight of 60.3 lb/bu and AGRIPR141 had the highest at 63.0 lb/bu.  PI 671855 had the highest protein content (16.7%) and PI 679964 had the lowest (13.7%), while the average protein level across the study was 14.9%.  Falling numbers ranged from 463.9 seconds (PI 671855, which also had the highest protein content) to 368.8 seconds (PI 642366), with an average of 407.5 seconds.

From seeding to harvest, this nursery received 4.9 inches of rain.
