Agronomy of new wheat and barley varieties response to N applied on wheat stubble locations

To evaluate yields and quality of new and existing wheat and barley varieties and their response to N.

Key messages
  • Barley yields averaged 1.78 t/ha compared to 1.64 t/ha for wheat.
  • The barley and wheat varieties differed in their response to added nitrogen (N). Cobra, Mace and Wyalkatchem yields increased at 40 kg/ha of N as did yields of Compass, La Trobe and IGB1337. The other varieties were not responsive to added N.
  • Barley had a higher tillering capacity than wheat.
  • Grain quality and price will influence the profitability of added N. The current high prices for barley grain make it a profitable option. However, barley is less tolerant to acid soils and so site selection is important, as is a good understanding of grain quality and end price.
