Time of sowing of wheat varieties at Grass Patch - DPIRD Crop Sowing Guide project locations
Aims

To determine the optimum sowing date and variety combinations to maximise yield and quality of wheat in WA.

Key messages
  • The highest yielding treatment was Calibre (RAC2721) sown on 28 April, achieving just over 4.6t/ha.
  • Yields of over 4t/ha were consistently achieved by mid-slow to slow maturing spring wheats sown on 14 April and quick to mid maturing spring wheats sown 28 April. This coincided with flowering occurring during August.
  • Despite being sown onto field pea stubble with 75kg N/ha applied, high yielding (4+ t/ha) treatments rarely met APW1 protein specifications, indicating that at these high yields greater nitrogen applications are required to achieve premium milling grades.
