To demonstrate the impacts of degree and timing of grazing of crops on yield.
Key messages
Moderate grazing up to Z30 and clip grazing after Z30 did not appear to have significant impacts on yield in 2012 when compared to early sown crops.
However, assessing the value of grazing to the farm systems is complicated as grazing can affect time of flowering and frost impacts. It can also increase water use efficiency, allow pasture paddocks to be deferred, reduce the need for supplementation and allow for increased stock numbers and/or crop area.

Thanks to Andrew Sutherland and his team, DAFWA Perth for threshing the hundred odd time x height harvest cuts. Luke Ledwith and family managed the grazing demonstraiton and bulk crop yield measurements.
