Objective:
To evaluate the performance of winter wheat varieties in northwestern Montana
Summary:
The trial was planted under rainfed conditions in 2018 on silt loam soil (but with know subsurface water recharge). The management information is available in Table 1. Only a handful of varieties experienced significant rust infection, including Decade, Brawl, MT 1793 and MT 1796. There was little to no lodging across the entire study, and yields were exceptional due to prolonged cool, wet weather in the spring. The high yields, along with lower-than-normal rates of N fertilization, likely contributed to the low protein levels seen in this study.
The average yield was 124.9 bu/A, with LCS Jet having the highest yield (145.7 bu/A) and SY 517 CL2 having the lowest (93.6 bu/A). LCS Zoom had the lowest test weight (58.0 lb/bu) and SY 517 CL2 had the highest (63.3 lb/bu); the mean test weight was 61.0 lb/bu. Average protein was 8.5%, with ASC 116 having the highest protein at 10.0% and Incline AX had the lowest at 7.4%. Other indicators of agronomic performance are given in Table 2.
