Barley agronomy, grazing and annual ryegrass locations

To compare the grain yield and quality of barley varieties with grazing and annual ryegrass (ARG).

Key messages
  • Simulated grazing significantly reduced grain yield.
  • Non-grazed controls were more competitive with annual ryegrass (ARG) reducing the ARG population by 58% compared to the grazed treatments.
