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
  • Wheat on wheat (following canola) yielded 4.91t/ha, almost 1t/ha less than the neighbouring first wheat trial after canola, which yielded 5.84t/ha.
  • There was no yield drop-off associated with wider row spacings (30cm and 337.5cm) in this wheat-on-wheat situation.
