Performance of second 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 second wheat (wheat on 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
  • Plant establishment at a 22.5cm row spacing was signifi cantly superior to 30cm, which in turn was signifi cantly higher than 37.5cm. The disc drill opener gave better establishment than the tine at the narrow (22.5cm) row spacing but not at the wider row spacing. 
  • Advantages with the narrow row spacing were seen early in the season in terms of plant population, dry matter (DM) and tiller production. These advantages did not translate to signifi cantly higher yield in this rotation position. This result was identical to the results of the 2010 trial when wheat on wheat yields showed a similar, but not signifi cant, trend for narrow row spacing (22.5cm) to be better than wide row spacing (37.5cm).
