Southern barley agronomy - how much nitrogen is too much, and when should I apply it? locations
Aims

To investigate the effects of delaying nitrogen application until GS31 on grain yield and quality by using differing nitrogen application rates across a range of popular malt and feed barleys.
 

Key messages
  • Westminster was the barley variety that gave the top gross margin with an application rate of 120 kg N/ha at GS31, closely followed by GrangeR (90 kg N/ha at GS31).
  • Oxford (45, 90 or 120 kg N/ha at GS31) yielded equal top with Westminster but the gross margin was hurt by the price difference between malt and feed barley varieties at the time of writing this report.
  • Application of N at GS31 gave significantly higher yields compared to application at GS22, across all varieties and N application rates. 
  • The most cost effective rate to consistently receive the highest yields was 90 kg N/ha.
  • Oxford was consistently the highest performer and the best choice for those who rarely make malt grade on their soils.
