Barley agronomy – nitrogen management in new barley varieties locations
Aims

To examine the nitrogen responses of new malt and food barley varieties and determine appropriate N management strategies for maximum yield and quality.

Key messages
  • Varieties responded similarly in yield and all quality parameters to applied N. Variety choice played a more important role on overall yield and quality than N management.
  • Averaged across all N treatments Fathom yielded highest at 3.30t/ha, and late maturing variety Wimmera the lowest at 2.47t/ha.
  • No applied N, yielded 2.88t/ha, while 40kgN, applied at GS30, yielded 3.12 t/ha.
  • Using the Greenseeker, improved agronomic N efficiency by more than 50% over all other N treatments.
