Does stubble height influence subsequent crops? locations

To answer the question 'Does stubble height matter?'

Key messages
  • Stubble height did not affect fallow efficiency at Weethallee following the 2013 or 2014 harvests.
  • Stubble height during the 2014 fallow did not impact on 2015 crop yields.
  • Leaving higher stubbles may reduce harvest cost but may also cause issues during fallow sprays and sowing. Individual producers need to target a stubble height that best suits their equipment and techniquies.
