Objectives:
Commercially available durum varieties and advanced breeding lines were evaluated for agronomic performance and fit at on-farm locations across the state of Montana. Sites chosen for the research considered the environment, growing conditions and soil types, and represent the major land areas for producers in those regions served by Northern Agricultural Research Center. The Liberty County location near Chester entered its tenth year of spring wheat testing in crop year 2023.
Methods:
The uniform off-station durum variety performance trial was seeded into chemical fallow ground during 2023. The trial consisted of 12 entries seeded in replicated, three-row, 22-foot plots on a 12-inch row spacing, utilizing a self-propelled cone seeder with Atom Jet paired row openers. All plots were trimmed to a harvest length of approximately 17 feet with a three-point rototiller. Plant height was measured from the soil surface to the top of the head, excluding awns, and percent sawfly cutting was visually estimated for each plot immediately prior to harvest. A ‘Wintersteiger’ small plot combine, funded in part by the Montana Wheat and Barley Committee, was used to harvest each three-row plot. Prior to measuring plot weight for yield determination, seed was either cleaned or weighed in-dirt as per protocols. Protein, test weight and moisture content were determined on a clean sample using a Foss Infratec 1241 near infrared analyzer. Falling number was determined using a Perten FN1700 according to the FGIS Directive 9180.38. Other variables specific to each individual trial are listed with the current year data tables.
Please note that research trial seed yield results recorded under wheat stem sawfly pressure are likely much higher than a producer should expect. Small plot variety trials are managed to assess maximum yield potential and are harvested in such a way that all stems and heads are picked up by the combine, regardless of lodging or cutting due to wheat stem sawfly. Pickup guards coupled with an extremely slow ground speed and an exceptionally low cutting height help researchers collect all heads in order to assess seed yield potential. If you are a producer in a wheat stem sawfly environment, although hollow stemmed varieties may be high yielding in research trials in your area, we strongly recommend against growing those hollow stemmed varieties. Please be aware that if you seed hollow stemmed varieties with wheat stem sawfly present, you are only creating a breeding ground for future generations of sawfly in your area and not helping combat the pest population.
Results:
This report contains both single-year and long-term data summaries limited to the most recent ten years. It should be noted that the 2023 data table in this report represents varietal performance for a single crop year at a single location, therefore cannot be considered representative of performance expected when differing conditions due to location, year and management are imposed. By itself, 2023 data shall not constitute in any form a recommendation for or against any variety or breeding line included.
Durum seed yields at Chester averaged just under 44 bu/ac (Table 1). ‘Mountrail’ produced the highest seed yield at nearly 50 bu/ac. ‘Alzada’, ‘Joppa’ and ‘MT Raska’ produced statistically equal seed yields to that of Mountrail. Test weights of all durum entries for this site averaged just over 55 lb/bu. Very minimal wheat stem sawfly cutting was observed in the trial. Yield, test weight, protein, falling number, plant height and sawfly cutting data for the 2023 Chester dryland spring wheat trial are summarized in Table 1.
Comparable averages are calculated using a standard check variety when not all entries are present in a specific trial for all years. Variety means are adjusted by multiplying the actual check mean by the ratio of the individual variety mean compared to the check mean for the same years as tested. All varieties are then directly comparable to each other when in the same nursery. A minimum of three years of data is necessary to be included in the comparable average calculation. Ten-year comparable averages (2014-2023) for durum seed yield and test weight at Chester are summarized in Table 2, while ten-year comparable averages for protein content and wheat stem sawfly cutting are summarized in Table 3. Based on the comparable average calculations, Alzada, MT Raska, Mountrail and ‘Grenora’ are the highest yielding varieties at Chester.
Summary:
Snow cover persisted into early April, minimally delaying seeding in several areas across the Hi-Line. Once established, the Chester site had the best stand uniformity of all spring wheat sites in northcentral Montana. With timely and above average precipitation throughout the growing season, the durum variety trial near Chester produced its highest seed yield since 2020.
This work has been strongly supported by producers in the Chester area, and by the Northern Agricultural Research Center Advisory Board. With budget and other resources allowing, it is planned to continue off-station spring wheat variety and breeding line testing in this area. The Chester location was reestablished in 2014 following a prolonged absence of uniform off-station spring cereal testing in Liberty County.
