Seeding rate recommendations for winter wheat in Ontario have long been standardized across seeding dates, soil types, and varieties. Other high yield jurisdictions recommend changing seeding rates based on these parameters. This study investigated the validity of current seeding rate recommendations, as well as the impact of seeding date and soil type on the seeding rates evaluated.

The high yield potential of early planted wheat is well documented. How low can you go with your seeding rate when seeded early, and are there any potential benefits to using a higher seeding rate when planting early or planting late? The results from this trial will provide recommendations for seeding rates throughout the entire planting season from ultra-early to ultra-late.
