Performance of first wheat under no-till full stubble retention (NTSR) using different drill opener and row spacings at Coreen locations
Aims

To evaluate the performance of different drill openers at a range or row spacings for first wheat following canola to improve water use efficiency (WUE) in no-till cropping and stubble retention systems in spatially and temporally variable conditions in the Riverine Plains.

Key messages
  • With 570mm growing season rainfall (GSR) 2010 wheat yeilds were more than double those experiences during 2009 in the same rotation position (wheat after canola).
  • Yield drop-off associated with the wide row spacing (37.5cm) was almost identical to 2009 results, with a 12% yield reduction compared with the narrow row spacing.
