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.
