MSU Agriculture research centers have three test plots for winter wheat in Chouteau County. Research plots are managed by MSU Western Triangle Agricultural Research Center (WTARC) south of the Knees, MSU Northern Agricultural Research Center (NARC) north of Loma and MSU Central Agricultural Research Center (CARC) west of Geraldine. A special thanks to John Miller (WTARC agronomist), Peggy Lamb (NARC agronomist) and Jed Eberly (CARC agronomist) for establishing and maintaining the Chouteau County test plots. The Extension office would also like to thank the Killion family, the McKeever family and the Davis family for donating the use of their land for MSU research.

Judee is the top yielding solid stem sawfly-tolerant variety at 74.6 bushels per acre followed by Warhorse at 69.7 bushels per acre.
NARC (Loma area) top three yielding winter wheat varieties (10- year average yield) from 2009-2018 include Northern at 56.5 bushels per acre, Keldin at 56.5 bushels per acre and SY Wolf at 54.4 bushels per acre. Judee is the top yielding solid stem sawfly-tolerant variety yielding 50.6 bushels per acre followed by Warhorse at 48.7 bushels per acre and Genou at 46.5.
CARC (Geraldine area) top three yielding winter wheat varieties for 2017-2019 were Keldin at 86.3, SY Monument at 83.8 and Northern at 82.6 bushels per acre. Loma was the top yielding solid stem sawfly-tolerant variety yielding 77.5 bushels per acre followed by Judee at 74.1 bushels per acre, and Warhorse at 73.1 bushels per acre.
Nutrien Ag Solutions has a plot between Carter and Fort Benton Montana. Top three yielding winter wheat varieties for 2016-2019 were Loma at 65.4, SY Monument at 64.0 and Decade at 62.3. Since Loma has a semi-solid stem, it would also be the top yielder for solid stem sawfly-tolerant varieties. Warhorse (61.4) and Judee (60.5) placed second and third.
