Section Title
Spring Wheat Early Planting
Trial Information
- The grower will plant a spring wheat variety on 2 separate seeding dates.
- The grower will plant the first strips of spring wheat when the soil temperature is in the range of 2 – 5OC and the second set of strips when the soil temperature reaches 5 – 10OC or his normal seeding time.
- Strips should be full length of the field (minimum 1000 ft.) and width to allow for a full “pure” pass with combine header.
- The grower will manage their crop as per their normal best management practices.
- Recent research from Collier et al. (2021) explored seeding spring wheat by soil temperature, rather than by calendar date.
- They investigated if early seeded wheat can make better use of early season moisture and miss extreme summer heat during flowering and grain filling. However, early seeding comes with risk, such as frost, poor emergence and slow growth.
- Results showed that initiating seeding into soil with temperatures between 2-6 °C resulted in no negative effects on wheat yield or protein, when compared to seeding at 8°C.
- The Collier et al (2021) study did not include research sites located in Manitoba. Current MASC data suggests that seeding early is important to maximize yield.
Results
No significant yield or protein differences were found between planting dates at these trial sites. Therefore, during the trial years, at these sites planting early did not impact wheat grain yield or protein levels
