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

To present results from the large plot focus farm trials of the Maintaining profitable farming systems with retained stubble in the Riverine Plains region project, which where 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
  • Under moist mid-April sowing conditions, there was a significant yield advantage (0.45t/ha) with one shallow-pass cultivation before establishing canola, compared with crops sown directly into standing wheat stubble.
  • The yield advantage of canola following cultivation correlated to crops with higher vigour, early dry matter (DM) and greater nitrogen uptake.
  • There was no significant benefit to mulching the first wheat stubble before direct drilling canola.
  • The additon of 40kg N/ha at sowing gave a significant yield increase to crops established directly into the first wheat stubble, but there was no significant advantage to the additional nitrogen where stubbles were cultivated or mulched.
