Oats can be a good crop for a beginning organic producer because the crop provides good early season growth to compete with weeds. In order to provide producers with oat performance data, twenty oat varieties were tested in three locations across Minnesota, South Dakota, and Wisconsin in 2017-2018. Results are summarized in this publication. Important management considerations for organic oat production, other than variety selection, have been summarized in an online extension article from University of Minnesota Extension which can be found at: [https://extension. umn.edu/small-grains](https://extension. umn.edu/small-grains)crop-and-variety-selection/organic-oat-production.  \nAgronomic characteristics such as maturity ratings, lodging scores and crown rust resistance for the varieties used in this trial are summarized in Table 1. Several grain quality and milling characteristics are summarized in Table 2. Average test weights for the trials are summarized in Table 3.  \nOat yields in the multi-state organic oat trials averaged 71 bu/acre in 2017-2018, ranging from 60 bu/acre at Lamberton, MN (2018) to 102 bu/acre at Evansville, WI (2017) (Table 4) . Varieties that were statistically in the top yield group include Betagene, Deon, Saddle, and Goliath. There was a 37 bu/acre difference between the best and worst performing variety in the trial. If one assumes a price of $5 .25/bu, that equates of a revenue difference of $194.25 per acre.  \nProducers need to consider several factors other than yield performance when selecting suitable oat varieties for organic production. Because conventional fungicides can’t be applied in organic production, it is recommended to choose a cultivar resistant to crown rust. In susceptible cultivars, infection with crown rust can cause severe yield loss and significantly reduce test weight and grain quality. Antigo, Deon, Leggett, Saddle and Sumo are cultivars with good levels of resistance to crown rust (Table 1) . Test weight is also a very important consideration and highly variety-dependent.  \nGrain specifications for organic food grade oats include a minimum test weight and a maximum proportion of thin kernels. Varieties which exhibited excellent test weight included Antigo and Sumo. Fan speed can be increased on the combine to increase test weight.  \nIt is usually recommended to consider as much performance information as possible when selecting a variety and to give more weight to information from trials close to home, as some varieties may be better suited to certain geographic areas. Also pay close attention to relative performance over many locations. This type of performance is an indication of yield stability. Performance over multiple years is also very important. Growing conditions in a single season may favor certain varieties and provide a poor representation of yield potential over time.  \nIt is important to remember that varieties may differ by 5 bu/acre or even more and still be statistically similar. This is due to inherent variability in the environment and the yield testing process.
