Trial details

Researcher(s) John Sykes (John Sykes Rural Consulting)
Year(s) 2008
Contributor Riverine Plains
Trial location(s) Balldale, NSW
Wheat maxiumum yield experiment locations
Aims

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

Key messages
  • Wheat responded to up to 20 kilograms per hectare of nitrogen (N) during 2008.
  • Wheat has not significantly responded to fungicides in 2008 or the other dry years.
  • Over the full term of the experiment (2005 - 2008), wheat responded significantly to both fungicide and an average of 40kg/ha/yr of nitrogen (range 20 - 80 kg/ha/yr).
