Trial details

Researcher(s) John Sykes (John Sykes Rural Consulting)
Year(s) 2005
Contributor Riverine Plains
Trial location(s) Balldale, NSW
Barley maximum yield experiment locations
Aims

To assess the level of input required to maximise yields of barley grown after wheat.

Key messages
  • Barley requires the same amount of nitrogen input as wheat to yield near its potential.
  • 80-92 kg/ha Nitrogen (N) is required to maximise yield.
  • Barley responds strongly to extra N when fungicide is used to control disease.
  • A preliminary program for growing barley is ready for farmers. Anyone interested should contact John Sykes.
