Impact of delayed harvest in barley locations
Aims

To investigate the yield and quality effects of a delayed harvest on a range of barley varieties.

Key messages
  1. In dry conditions there is no yield penalty when delaying harvest.
  2. Harvest of Skipper, La Trobe and Compass should be prioritised as they are more susceptible to head loss. 
  3. To minimise risk associated with delaying harvest consider sowing only manageable areas of susceptible varieties.
