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
  • Grazing crops can offer the ability to spell pastures, however careful management needs to be practised to ensure there are no grain yield losses. Grain yield losses can very easily result in a negative profit from grazing crops.
  • In this case I suggest that the paddock was grazed heavily in the days leading up to removal of the paddock and this resulted in poor recovery of the crop from grazing.  In hindsight I feel that fewer yield losses would have resulted if there was more bulk left leading into stem elongation.
  • On the 17th August the Grain & Graze II trial site was visited by the Northern Agri Group (NAG) field day.  During the day we had over 100 growers discuss the pros and cons of grazing crops.  Both Don Nairn and I addressed the field day and had good feedback about the system.
