Trial location(s) Irwin, WA
Grazing cereals demonstration locations
Aims

To assess whether the effects of grazing wheat with sheep during the growing season. Factors being assessed are yield and quality, dry matter production and grazing value.

Key messages
  • There was no yield penalty from grazing in 2011. 
  • This was probably due to removal of the sheep at closer to the ideal (i.e. Z31) crop stage and possibly the reduced grazing density as well as a favourable finish to the season. 
  • This resulted in a profit of $29.89 in 2011 for the grazed treatment compared to -$29.74 for the grazed in 2010.
