Objective: evaluate yield and quality of wheat varieties seeded at different seeding rates based on thousand kernel weight (TKW) in the Peace region

This research will build on previous research done in 2019, 2020, 2021 in the Peace region that evaluated the impact of seeding rate on crop yield, test weight and protein content on both AAC Brandon and AAC Connery. The study demonstrated that higher seeding rates (28 and 37 seeds foot-2), led to significantly higher yield and test weights on both varieties. However, the highest seeding rate (37 seeds foot-2) also had significantly lower protein content. Thus, we wish to evaluate two more commonly grown varieties grown in the Peace region (AAC Viewfield and AAC Redberry). AAC Redberry is not prevalent in the North Peace and Mackenzie regions, however it is early maturing (three days earlier than the AAC Brandon variety) and thus would likely be a good fit. AAC Wheatland VB was selected as it is a new midge tolerant variety with a similar maturity to AAC Brandon, and a slightly higher yield advantage of up to 4 bushels acre-1 (AFSC Yield Alberta 2021).
