Understanding canola variety development to improve yields locations

To investigate options to increase canola profitability and reduce production risk with tactical agronomy advice underpinned by physiological insights.

To improve the water use efficiency of canola, through early sowing and correct variety selection. 

Key messages
  • The 2015 season was cooler than 2014 which affected how canola varieties developed and grain yields.
  • Early sowing presents a good opportunity to improve canola water use efficiency and yields but variety selection is important.
