Objective:

To evaluate the performance of selected spring wheat in farmer-field production environment in northwestern Montana.

Personnel: 

David Larson, Jessica Pavelka, Jason Cook, Hwa-Young Heo, Jessica Torrion

Summary:

There were 25 entries of spring wheat planted as a farmer-field trial. This trial was under rainfed conditions and seeded on 27 April 2023 and harvested on 17 August 2023.Cultural practices are provided in Table 1. This farmer-field trial received 3.17 inches of rain.

Average yield was 57.1 bu/A, PI 690450 had the highest yield with 63.5 bu/A and WB9879CLP was the lowest yielding with 49.2 bu/A. The average protein was 15%, with MT 21074 having the highest protein (16.1%) and MT 2050 being the lowest (14.4%). The average heading date was day 179 (28 June) with PI 690450 heading the earliest (day 168; 17 June) and PI 679964 as the latest (day 176; 25 June). The average test weight was 57.5 lbs./bu, AGRIPR 10 was the highest (59.5 lbs./bu) and PI 676978 the lowest (56.3 lbs./bu). Average falling number (FN) was 588 seconds, and FN values of all entries were above critical level (330 seconds) for amylase activity.
