OMAFRA: Maximizing winter wheat potential through planting date

September 12, 2023  By Field Crop News

Ontario’s winter wheat planting recommendations were established in the 1990s using research trials conducted across the province. This led to the development of the Ontario winter wheat planting date map. The research found that, for every day planting is delayed beyond the optimum planting date for a region, 1.1 bushels per acre (bu/ac) of yield potential is lost.

However, with newer genetics and a changing climate, many wondered about the yield potential of later-planted wheat and what really leads to increased yields in earlier planting dates. These questions have been answered thanks to new research conducted by Emma Dieleman at the University of Guelph, Ridgetown Campus, under the supervision of Dave Hooker and Joshua Nasielski, which provides greater insights into why early planting is so important to maximize winter wheat yield potential. |READ MORE
