Dual purpose (Graze & Grain) cropping locations
Aims
  • To demonstrate and refine the technique to suit the many mixed farmers on Kangaroo Island.
Key messages
  • 2007 results showed two varieties experienced statistically significant yield penalty from mowing when medium maturing varieties were mowed at growth stage 30 (given appropriate crop management).
  • Early sowing thought to be very critical to minimizing yield penalty from grazing - to be researched .
  • Crop management will be different for both graze/grain versus pure grain crops - to be researched.
  • Grazing crops gives pastures a chance to establish and grow at optimal growth rates during winter.
  • Sheep can be used to selectively graze weeds - to be researched.
