Poplar, Wibaux, and Plentywood).

OBJECTIVES: To evaluate the performance of experimental lines and named varieties of spring wheat
across eastern Montana.
MATERIALS AND METHODS:
Location:
− Roosevelt county (Poplar)
− Sheridan county (Plentywood)
− Valley county (Nashua)
− Wibaux county (Wibaux)
RESULTS:
Due to the severe hail damage at the Sheridan County site, the trial at this location was abandoned.
Results from the other three off-station locations are presented in Table 1-3. Due to the drought, the yields
at Roosevelt County were low.
