Objectives:

Commercially available spring barley 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 (NARC). In 2009, three off-station spring barley variety trials were dropped from the NARC off-station testing program due to extensive feeding by deer and antelope, which made results meaningless. In northcentral Montana, barley production makes up 22 percent of the state’s production. Because farmers base production decisions on variety performance data generated under local conditions, collaboration in the standardized off-station spring barley variety trial was reestablished in 2022.

Methods:

The uniform off-station barley variety performance trial was seeded into chemical fallow ground during 2024. The trial consisted of 25 entries focusing on seed production of three different end use markets including malt, feed or forage. The trial was seeded in replicated, 3‑row, 22‑foot plots on a 12‑inch row spacing, utilizing a self‑propelled cone seeder with Atom Jet paired row openers. All rows of each plot 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. If observed, crop lodging and percent sawfly cutting was visually estimated for each plot immediately prior to harvest. A ‘Wintersteiger’ small plot combine, funded in part by Montana Wheat and Barley Committee, was used to harvest each 3-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. Plump seed was determined by calculating the percent of barley that remained on top of a 6/64” x 3/4” inch slotted-hole sieve after mechanically shaking for 30 strokes.  

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 2024 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, 2024 data shall not constitute in any form a recommendation for or against any variety or breeding line included.

The 2024 Havre off-station dryland spring barley trial data was analyzed by barley type or end use. Spring barley seed yields for the malt and feed entries at Havre averaged 98 bu/ac (Table 1). The feed barley breeding line ‘MT18M10106’ was the highest yielding entry at 116 bu/ac. ‘LCS Odyssey’ was the only entry to produce seed yields statistically equal to that of MT18M10106. Test weights averaged over 58.4 lb/bu, with Haxby being the heaviest at nearly 57 lb/bu.

Seed yields for the forage barley entries averaged 98 bu/ac and breeding line ‘MT20_F108_13’ was the highest yielding entry at over 107 bu/ac (Table 2). ‘Hays’, ‘Lavina’ and one other breeding line produced seed yields statistically equal to that of MT20_F108_13.

Seed yield, test weight, protein, plump kernels, heading date, maturity date and plant height, as appropriate, for the 2024 Havre off-station dryland spring barley trial are summarized according to end use in Tables 1 and 2.

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. Because the barley trial was initiated near Havre in crop year 2022, comparable averages for a limited number of entries are available for the first time this year. Multi-year yield and test weight data are available in Table 3 while plump kernel and protein data are available in Table 4.  

Summary:

Spring barley near Havre had great stand uniformity and received above average precipitation in May resulting in increased tillering, biomass, and seed production. Below normal temperatures during June limited environmental stresses during seed fill which contributed to high test weights and high plump kernel percentages.

Producers have been asking for information on spring barley varieties in northcentral Montana for several years. Because named varieties were dropped from the intrastate trial grown at the research center, and consistent data could not be obtained from small plot on-farm trials due to deer and antelope grazing, it was decided that the best option would be to grow the off-station trial at Northern Agricultural Research Center, behind the protection of a permanent deer fence. With budget and other resources allowing, it is planned to continue growing the standardized off station spring barley variety trial on-station to better serve producers in northcentral Montana with public and private variety information.
