Active stubble management to enhance residue breakdown and subsequent crop management locations

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.
Key messages
  • A highly variable trial with no significant differences in monola dry matter (DM) accumulation, nitrogen uptake or yields due to subble management.
  • The 2014 cultivation treatments carried out before sowing the canola crop during the first year of the project significantly increased the yield of the following oat crop established using no-till stubble retention (NTSR).
  • The yield increase in the following oat crops was reflected in significantly more biomass accumulation by the flag leaf.
