The effect of nitrogen application on grain yield and grain protein concentration of six wheat varieties – Parkes 2015 locations
Aims

This experiment evaluated the effect of variety and nitrogen rate on grain yield and protein concentration for six wheat varieties.

Key messages
  • Suntop was the highest yielding variety (4.48 t/ha).
  • Lancer achieved high protein, high test weight and low screenings at all nitrogen application rates.
  • Grain yield increased as nitrogen application rates increased, but there was no significant increase in yield above 20 kg N/ha applied nitrogen.
  • Applying 160 kg N/ha resulted in a yield decrease.
