Combating ARGT through the use of safeguard ryegrass - PIRD locations
Aims

To determine if the livestock carrying capacity of pastures in the eastern Wheatbelt of Western Australia, including those on mildly saline soil, can be increased by replacing native ryegrass with the Safeguard variety of ryegrass.

Key messages
  • An intended comparison between native ryegrass and Safeguard ryegrass became a comparison between what is probably Italian ryegrass and Safeguard ryegrass.
  • It was observed that in early November sheep grazed the Italian ryegrass in preference to the Safeguard ryegrass.
