The first part of this trial was to demonstrate that growing canola (with effective weed control options) followed by a high value legume (with higher economic value) can lead to an effective and profitable double break crop sequence. The contribution of an early sowing date versus a traditional sowing date to increase the profitability of the legume crop was also evaluated in this trial. The second part of this trial is to determine the economic value of growing canola followed by a high value legume, and the impact of this rotation on the grain yield and profitability of a cereal crop in the first year following the double break crop sequence
• Early sown chickpea achieved the highest grain yield (4.4 t/ha) of all treatments
• The benefit to cereal production will be evaluated in the 2022 season

This is a GRDC funded project, WMG2003-001SAX, led by the West Midlands Group, and managed by the Liebe Group. This site is one of four sites across the Wheatbelt that aims to evaluate the crop rotation benefit of a double break crop rotation. Thanks to the Hyde family for their assistance, hosting, implementing and managing the trial. Thank you to Chickpea Breeding Australia (CBA) for providing CBA Captain Chickpea seed for this trial |
