Objective:
To evaluate the performance of selected spring wheat varieties in a production environment in northwestern Montana
Personnel:
Clint Beiermann, Jason Cook, Hwa-Young Heo, Jessica Pavelka
Summary:
The spring wheat off-station trial was planted on April 28th, 2022 (Table 1). A total of 3 inches of rainfall was received during the growing period. The trial was placed in an irrigated field near Polson, MT.
The average yield was 107.3 bu/A, with a high of 119.1 bu/A for Lannin/MT 1338 to a low of 89.1 bu/A for NS Presser CLP. The average test weight was 61.3 lb/bu. The highest test weight was 64.0 lb/bu for SY Soren and the lowest test weight was 56.6 lb/bu for NS Presser CLP. The average protein content was 14.9%. The highest protein content was 15.6% from VIDA and the lowest was 13.7% from WB Gunnison. Lodging was visible on all but seven varieties, ranging from slight to severe with the highest lodging percentage at 98% for MT1572/MT1133/CHOTEAU/YELLOWSTONE and VIDA (Table 2).
