Sum18-14 N x K x Wetter, Binnu


To evaluate if wetter coated seed improves wheat establishment in drier conditions and if this results in more effective use of nitrogen (N) and potassium (K) fertilizer application.

  • Wetter coated seed significantly improved establishment by an extra 10 plants/m2 (p=0.04).
  • There was a significant NDVI difference between N rates (p
  • Yield significantly increased with N application.
    There was a 46% yield increase from 6 kg N/ha to 60 kg N/ha. Using K and wetter coated seed had no effect on yield or grain quality.
  • Protein was relatively low across the trial and all treatments went ASW1.
    Profits increased with yield from $730/ha up to $1070/ha.
