Yields are expressed as a percentage of check as this make the data comparable to the regional variety trials hosted by the government of Alberta and to the results in the seed guides. SARDA small plot trials are purposefully conducted on the most consistent and highest performing land possible, which allows the differences in varieties to be highlighted instead of other limiting factors such as water, nutrients or other potential deficiencies. This results in high yielding plots compared to what a grower would consistently average across a field or a farm. 2018 growing season was a particularly challenging year. Yields were lower than normal and many of the varieties did not complete maturation. When this happens, the data is more variable and less reliable. The other 2 locations for the trial did not produce good data and therefore are not included in our report
S.D.: Significant Difference: Letters used to identify statistically calculated significant differences between yields of varieties. Note: Harvest was reclassified as the new Canada Northern Hard Red Spring class by the Canadian Grain Commission in 2018. Other varieties will remain in the current class, however Redwater is scheduled to move into the Canada Northern Hard Red Spring class on August 1, 2021. Note: CDC Landmark VB, CDC Utmost VB, AAC Cameron VB and CDC Titanium are wheat midge tolerant varieties.
