Effect of sowing date on flowering and grain yield of ten canola varieties in a high yielding environment – Wallendbeen 2019 locations
Aims

This experiment was conducted at Wallendbeen, typically a high rainfall area in the South West Slopes, to assess canola’s yield potential across different sowing dates in a high yielding environment. Varieties were chosen to represent a diverse range of canola types to compare the different phenologies (including winter types), the breeding type (OP – open pollinated vs hybrid) and herbicide tolerance (TT vs non-TT – triazine tolerant) on three sowing dates: late March, mid April and late April.

Key messages
  • In 2019, the highest yields came from sowing in late March due to the dry spring conditions and only mild frosts at Wallendbeen.
  • Nuseed Diamond was the highest yielding variety from all sowing dates. The highest yield was from the late March  sowing date.
  • The winter varieties were lower yielding than the spring types, with yields declining from later sowing dates.
  • Open pollinated triazine tolerant varieties were generally lower yielding than the hybrid Clearfield® varieties with similar phenology.
