  • No 100 Sowing Rates And Times For Autumn Wheats

No. 100 Sowing rates and times for autumn wheats

Feature placeholder

Key Points

  • Grain yields for all cultivars (Centaur, Claire, Savannah and Weston, all true winter wheats) were highest from the April sowing, Savannah yields declining the most from May sowing.
  • Centaur and Claire were most prone to lodging, Savannah slightly less vulnerable and Weston the most resistant.
  • Data from 3 years of time of sowing trials indicates that Centaur and Claire perform best from plant populations around 100-150 plants/m2.
  • Savannah and Weston need to be sown at around 150 plants/m2, but this is based on only one year’s trials in Canterbury.
  • At all sowing times and for all cultivars, 75 plants/m2 appears to be too low.
  • Late May or June sowings for all cultivars should be aimed at 150 plants/m2 or more.
  • Ear populations were much higher at Highbank than Norwood this season and lower overall than previous years.

Farm-saved seed royalty system

Farmers who save and replant legally protected cereal varieties can voluntarily declare their usage and pay a breeder royalty. The declaration system applies to all farm saved seed barley, and to farmer saved wheat if the resultant wheat crop does not pass through an end-point royalty collection agent.
