The use of two break crops in a row as a double break crop sequence has been successfully used to increase the grain yield of successive wheat crops in South Eastern Australia, and this study has tested this approach in the WA wheatbelt region. 
Four demonstration sites were established in 2017 near Bencubbin, Corrigin, Miling, and Calingiri. These sites were established in paddocks with a history of root diseases or weed populations that a single break crop could not address, and which were sown to a break crop, pasture, or fallow in 2016. In 2017, plots of up to 2 hectares in size were established using grower equipment for a range of break crop options that the grower identified as options to integrate into their farming system. The remaining area of the paddock was sown to either wheat or canola depending on grower’s paddock plan. All sites were sown to wheat in 2018.
