The benefit of break options to wheat production at Appila locations

To address the need for a non-cereal crop and pasture options to provide profitable rotational crops, disease breaks and weed control opportunities for cereal production in low rainfall regions of south-eastern Australia.

Key messages
  • All two year break options increased yield by 0.5–1.0 t/ha compared to continuous wheat.
  • Single year breaks improved wheat yields in 2012 and also appeared to increase them slightly in 2013.
  • Grassy weeds had a major impact on wheat yields.
  • Only 2 year breaks reduced grassy weed seed banks substantially compared to the continuouswheat control.
