Title: Off-station spring barley cultivar evaluations for the Western Golden Triangle area of
Montana
Principle Investigators: Gadi V.P. Reddy, Professor of Entomology/Ecology, Western
Triangle Ag Research Center
Personnel: John H. Miller, Research Scientist, Julie Prewett, Research Assistant, WTARC,
Conrad, MT, and Jamie Sherman and Liz Elmore, MSU PSPP Dept., Bozeman, MT.
Cooperators: Mark Suta, East of Cut Bank, MT

Inbody Farms, Northeast of Choteau, MT
Objectives: There are diverse cropping environments within the area served by Western Triangle
Agricultural Research Center. Each off station location has its own unique environment and
soils. Producers in the various locations are interested in variety performance in the local area.
To this end the objective is to evaluate spring barley varieties under the local conditions with
respect to yield, test weight, plant height, plump seed, thin seed and seed protein. The
environmental conditions at the off station nurseries can vary greatly from those at WTARC. The
research center strives to provide growers of the western triangle area unbiased information of
various spring barley varieties.
Methods: Off station barley nurseries consist of 25 entries replicated three times, seeded with a
four row plot seeder on one foot spacing. All plots were planted on no-till chemical fallow. Plots
were trimmed, measured for length, and then harvested with a Hege 140 or a Wintersteiger
Classic plot combine. Spring barley seed was not cleaned prior to collecting yield data.
Results: Results are tabulated in Tables 1 thru 10. The irrigated off-station spring barley nursery
data are presented in Tables 1 and 2. Table 3 is for the Choteau location, with multi-year data
presented in Table 4. Tables 7 and 8 are for the Devon location, with Table 9 and 10
representing the ‘Knees’ location. The Cut Bank data are presented in Tables 5 and 6. Table 11 is
the soil test results from each location.
Overall, the crop year temperatures where cooler than 32 year average at the research center,
May, when we could have used some cooler temperatures, was 5.2 degrees warmer than the
average. But the overall average temperature for the year from September to August was 3.8
degrees cooler than the 32 year average. The winter temperature, from September to March was
well below average, with February being 15.5 degrees colder than the 32 year average. March
and April were 9.6 and 7.1 degrees colder than the 32 year average. May was the only month that
had a temperature that was above the average with a temperature 5.2 degrees. September through
March were at or above the average precipitation for those months. Then May through August
were drier than the 32 year average. Overall, precipitation was average for the year with respect
to the 32 year average.
