Assessing Yield Prophet as a tool to assist growers in determining crop nitrogen requirements in the West Midlands locations
Aims

To test the Yield Prophet tool to determine its relevance and usefulness to growers of the West Midlands region in determining the most efficient and effective nitrogen strategy.

Key messages
  • The high ryegrass burden, particularly on the TOS1 plots impacted on the usefulness of the yield prophet tool for this time of sowing as it does not take into account other yield limiting factors.
  • High rye grass burden on TOS1 had significant impact on yield (approx 1.2-1.3 t/ha).  As such we have learnt that site selection (most especially with herbicide resistant weeds) is critical in order to conduct meaningful trials.
  • No difference in Yield Prophet forecasts between the two cultivars Mace and Bonnie Rock. This was also expressed in the harvest results, in direct contrast to the very dry, early finishing 2010 season, where Mace out yielded Bonnie Rock in all treatments.
