Aims

To explore management impacts on wheat grain quality.

Key messages
  • Severe drought conditions affected the results of this trial (grain yields 0.60 to 1.02t/ha), with only 130 mm for April – October and 171mm for the calendar year recorded at the trial site.
  • The wheat variety Ventura, showed the benefits of quicker maturity over Sunstate in such extreme seasonal conditions. 􀂃 Plant density was not found affect grain yield or quality in a very tough year.
  • Precision agriculture can be used for on-farm trials to produce statistically valid results, thereby offering an alternative to small plot trials.
  • The broadacre trial will be repeated in 2007 at Northparkes Mine.
