Nitrogen response of eight wheat varieties – Gilgandra 2015 locations
Aims

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

Key messages
  • This site was very responsive to nitrogen (N) application. Yield and protein increased in all varieties, even up to the highest applied rate of 160 kg N/ha.
  • Yield averaged across varieties increased from 2.80 t/ha with no application of N up to 3.58 t/ha with the application of 160 kg N/ha.
  • Grain protein levels across varieties rose from 9.8% (nil applied N) to 12.4% with 160 kg N/ha.
  • Screening levels were not affected by N application rates up to 80 kg N/ha but rose slightly from 2.7% to 3.8% with 160 kg N/ha.
  • Kiora was the only variety which produced screening levels above 5% which were exacerbated by higher N application rates of 80 and 160 kg N/ha.
