Delayed harvest of barley - harvest treatment locations
Aims

To compare the yield and grain quality of barley varieties when harvest is delayed.

Key messages
  • Compass, Commander, Scope CL and Fathom were the varieties most affected by lodging when harvest was delayed in a very high yielding environment.
  • Spartacus CL and Oxford had better head retention than Fathom and Westminster which were the poorest.
  • Delaying harvest by three and a half weeks incurred a 2t/ha yield loss. In an 8t/ha crop this equates to one per cent of yield per day lost on average (based on 2016 data).
