Managing dry sowing for wheat yield and grain quality in wheat-canola-wheat system through variety selection and agronomy at Wongan Hills locations
Aims

To investigate the value of nitrogen on the profitability of new wheat varieties in early (dry sowing) and late sowings in canola/wheat system at Wongan Hills

Key messages
  • Sowing the shorter maturing varieties, Emu Rock and Corack in early May was less productive than sowing Cobra, Mace, Magenta and Wyalkatchem.
  • In 2013, the varieties sown in late May were higher yielding than varieties sown in early May however, screenings of Magenta and Emu Rock were greater than 5%. This response will vary from season to season so the disadvantages and advantages of early sowing need to be clearly considered.
  • Nitrogen application increased wheat yield by 4.8 kg/ha for each kilogram of nitrogen (averaged across variety and sowing time) in 2013.
