The authors of this paper note in the conclusion: “Wheat yields achieved by growers in SW Vic have increased dramatically over the last decade. This has been partly due to the availability of better adapted cultivars and their interaction with improved management (crop sequence, time of sowing, N fertiliser, fungicides)”.

The take home messages from this GRDC funded research are below. Please access the full paper via the link below for methodology, references, acknowledgements and discussion.

Take home messages from the paper include:

  • Use appropriate combinations of cultivars and germination dates to ensure crops flower during the optimal period and have accumulated enough dry matter to intercept all incoming radiation by the time of flag leaf emergence.
  • Cultivars with short, erect flag leaves use radiation more efficiently, and most popular currently available cultivars in the high rainfall zone (HRZ) feature this trait (BeaufortRevenueTrojan).
  • Genetic yield potential needs to be protected with fungicides where appropriate and supported with sufficient nitrogen (N) to achieve economic yields.
