Can we extend the sowing window of canola in WA: #2 Wongan Hills locations
Aims

To investigate yield and phenology of canola varieties when sown in March to provide better advice to agronomists and growers about the best varieties to use and safe sowing and flowering windows.

Key messages
  • Yield were impressive; 1.9t/ha from April 26 and 2.2t/ha from May 17.
  • Mid-season maturity varieties showed the greatest plasticity in plant development across sowing dates and may be a good option over a wide sowing/establishment period.
  • Short season hybrids may enable the sowing window to be extended later with reduced risk.
  • Long season varieties yielded poorly from these sowing dates.
