Effect of nitrogen rate and sowing rate on the grain yield and quality of barley locations
Aims

Eight barley varieties were sown at Condobolin and Parkes to assess the varietal response to N application and seeding rate on grain yield and quality.

Key messages
  • La Trobe and Compass displayed the best combination of yield and quality traits for achieving malt specification.
  • The environment, or experiment site, had a greater effect on yield than variety, nitrogen (N) rate or sowing rate. Low rainfall at Condobolin resulted in significantly lower yields than at Parkes.
  • The sowing rate did not significantly affect yield above 150 plants/m2 at Condobolin or Parkes.
  • Nitrogen (N) applications, in the absence of adequate rainfall, can have a negative effect on yield.
