Aims

To demonstrate the effectiveness and possible yield advantages of Kellalac wheat using two different fertiliser rates with and without PR70 Release treatment.

Key messages

In our demonstration the higher fertiliser (DAP) rates produced higher yields, slightly higher protein and also slightly higher screenings when compared to the lower rate of DAP, as you would expect. The PR70 did not have any influence on yield at the lower rate of DAP, however at the higher rate of DAP the PR70 treated plot yielded 400 kg/ha less than the untreated plot. Therefore our trial demonstrates that PR70 did not produce significantly beneficial results in our area this year. More extensive replicated trial work is now
needed in our soil type to confirm the potential benefits of PR70.
