Can we extend the sowing window of canola in WA: #3 Beverley locations

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
  • Yields were relatively stable across sowing times ranging from 2.2 to 3.1 t/ha.
  • Early and mid-season hybrid varieties out-yielded the open pollinated varieties of the same season length.
  • These hybrids combine early flowering, high biomass and in some cases a long flowering period.
  • In general varieties had substantial plasticity and growers may be able to use a few varieties across a wide range of emergence dates; this is important if pre-ordering hybrid seed and/or dry sowing.
