Barley agronomy – nitrogen management in new barley varieties locations
Aims

To examine the appropriate management combinations of sowing date, nitrogen rate and timing required to maximise yield and quality in new malt varieties and food variety Hindmarsh.

Key messages
  • Higher grain yields were achieved in all varieties from early sowing in 2011.
  • Buloke and Commander were not yield responsive to nitrogen despite early biomass responses at both sowing dates.
  • Hindmarsh was more responsive to nitrogen than Buloke and Commander, showing an average 0.6 t/ha response to nitrogen across both sowing dates.
  • Grain protein exceeded 12% with delayed sowing, while the strategic approach to applied N achieved protein levels less than 12% at earlier sowing in Buloke and Commander.
