The effect of variety and regional nutrition strategies on crown rot severity in Merredin locations
Aims

To determine the effect of common district nutrition packages in Merredin on crown rot index (incidence x severity) of wheat and barley varieties.

Key messages
  • In 2017, the crown rot index (incidence x severity) of wheat was influenced by nutrition strategy, with disease index being the greatest at the highest N rate. There was a strong negative correlation between crown rot index and yield under different nutrition strategies.
  • In 2017, the crown rot index of barley was only influenced by variety: nutrition had no significant effect.
