Understanding the risk of heat stress: what do we know about the likelihood and consequence? locations
Aims

To investigate whether we could show any affect on field wheat yield after just one hot day.

Key messages
  • When considering the time of flowering it is apparent that a warmer, low rainfall location like Minnipa (flowering in September) may have less risk of heat events than a medium rainfall region like Roseworthy (flowering later in October).
  • A purpose built chamber was able to function well in the field and heat the enclosed air to 35oC.
  • More work is needed to quantify the impact of hot days on wheat yields.
