Effect of sowing date on phenology and grain yield of twelve canola varieties - Canowindra 2015 locations
Aims

To evaluate the effect of sowing date on phenology and grain yield of 12 canola varieties ranging from long to short season phenology types. 

Key messages
  • Early sowing exacerbated phenological differences between the varieties.
  • The spread of days to reach 50% flowering within each time of sowing (TOS) varied by 35, 26 and 14 days in TOS 1, TOS 2 and TOS 3 respectively.
  • The highest yield was acheived by Nuseed GT-50 (3.9 t/ha) sown on 1 May.
  • Hyola 600RR was the highest yielding variety when averaged across all sowing dates.
  • The sowing time had a neglible impact on grain yield. 
  • The biomass at 50% flowering was greatest in TOS 2 (9.92 t/ha) followed by TOS 1 (7.93 t/ha) and TOS 3 (9.23 t/ha).
  • There was strong correlation between biomass at maturity and grain yield, i.e. a higher biomass produced a higher yield.
