Nitrogen x sowing rate trial in barley and wheat locations
Aims

To determine the effect of sowing rate, nitrogen fertiliser rate and timing on wheat and barley crop establishment, tiller production, head counts at harvest, grain yield and grain quality.

Key messages
  •  Delaying post sowing applications of nitrogen (92 kg/ha N) to the flag leaf stage for both Kellalac and MacKellar at the Gnarwarre site, resulted in the best grain yield and grain quality.
  • Application of nitrogen (35 kg/ha N) to barley at the early jointing stage (GS32), gave the best grain yield and quality at Gnarwarre.
  • Late nitrogen applications appeared to result in more flower sites (florets) filling with grain for both wheat and barley. 
  • For further conclusions please see the attached trial report.
