The NDSU Oakes Irrigation Research Site will hold its annual field day July 28. Refreshments and rolls will be served starting at 9 a.m., with the tour beginning at 9:30 a.m.

Juan Osorno, NDSU dry bean breeder, will discuss dry bean varieties and production. Susie Thompson, NDSU potato breeder, and Nick David, NDSU Extension potato specialist, will address irrigated potato variety studies.

The tour will stop at a site of a sugar beet variety trial where 16 glyphosate-tolerant varieties are being tested. The trial is a part of the Non-food Sugar Beet to Advanced Biofuels project.
