Nitrogen response of eight wheat varieties – Merriwa 2015 locations
Aims

To determine the effect of N application on the yield and grain quality of eight popular bread wheat varieties at Merriwa in central NSW in 2015. 

Key messages
  • There was a significant response in yield and grain protein across increasing rates of applied nitrogen (N) in all varieties.
  • Yield averaged across varieties rose from 2.88 t/ha with no applied N, to 4.06 t/ha with 160 kg/ha of applied N.
  • Grain protein levels across varieties increased from 9.0% (nil applied N) to 12.2% with 160 kg/ha of applied N.
  • Screening levels were not significantly affected by increasing N application rates in any variety and averaged close to 6% across varieties and N rates.
