Barley agronomy, seeding rate and annual ryegrass locations
Aims

To investigate barley varietal performances under various seeding rates and the influence of annual ryegrass.

Key messages
  • Annual ryegrass did not affect crop establishment, but did reduce grain yield.
  • Increasing the seed rate from 80 seeds/m2 to 150 seeds/m2 had no significant impact on grain yield, however, increasing the seeding rate to 220seeds/m2 significantly reduced grain yield, by 13%.
  • At 220 seeds/m2 25% of the annual ryegrass survived, compared to 45% at 80 seeds/m2.
