The project seeks to:

• investigate, demonstrate and extend cultural practices that will assist growers to adopt no-till stubble retention (NTSR) in medium and higher-rainfall environments;
• build on findings from the previous Riverine Plains Inc. Water Use Efficiency (WUE) project; and
• extend the frontier of agronomic knowledge for crops grown in NTSR systems.

• There were significant increases in dry matter (DM) accumulation, nitrogen (N) uptake and crop canopy greenness where second wheat was established following cultivation with additional nitrogen, however there was no yield benefit.
• Over four years of research (2014–17) at the Coreen focus farm there has been no benefit to either cultivating, burning or additional nitrogen at sowing with cultivation over the no-till stubble retention (NTSR) control.
• Growing a faba bean crop instead of a second wheat crop increased the yield of the following wheat by 0.34–0.47t/ha in 2016 and an average of 2t/ha in 2015, however there was no evidence that the legume benefit of the faba beans influenced canola sown two years later (in 2017).
• Burning first wheat stubbles before establishing second wheat has offered no yield benefit, despite indications of better tillering, higher DM and superior yellow leaf spot (YLS) control.
