Aims

To support growers with agronomic decisions such as sowing time and variety selection to enhance industry profitability through improved wheat yields and grain quality

Key messages
  • Crop yields declined by an average of 31 kg/ha/day when sowing was delayed from the 20th May to the 2nd June.
  • Delaying seeding from 2nd June to the 15th June resulted in an average yields decline of 45 kg/ha/day.
  • There were not any significant interactions between varieties in their response to delayed sowing time from 20th May to the 15th June. -
  • The top performing AH/APW varieties were Carnamah, EGA Bonnie Rock, Espada, Katana, King Rock, Mace, Scout, Wyalkatchem and Zippy. Screenings of these varieties was less than 5% at each sowing time.
  • The varieties Binnu, EGA Bonnie Rock, Espada, Fang, Lincoln and Yandanooka produced screenings greater than 5% when sown in mid June.
