Can We Extend the Sowing Window of Canola in WA1 Tenindewa 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
  • Overall yield from May 17 sowing was impressive for this AgZone, at 1.6 t/ha.
  • Delayed sowing by 34 days, to June 20, led to 1042 kg/ha less yield – 30 kg/ha/day.
  • Short season hybrids could extend the safe sowing window later in this environment.
  • Difficulty establishing canola in hot conditions could limit how far the sowing window can be brought forward.
  • To take advantage of early autumn rains in this environment larger seeded broadleaf species that can be sown deeper should be tested.
