Management of grazing crops to reduce the incidence of frost in the Albany Port (Dumbleyung) locations
Aims

To value-add to grazing crops as frost mitigation tool by investigating the interaction of time x height of (simulated) grazing on wheat crop recovery and delay in flowering window.

Key messages

Later grazing may have benefits in severely frost prone areas, but in the event that there is no frost, yield will be compromised. Grazing has successfully delayed flowering date and for the early grazing it would appear that there is roughly a 1 day delay in flowering for 2 days grazing.
