What are predicted yields on EP for 2022? 13 October update

Yield Prophet predicted yield reports 13 October 2022 update #5

The Resilient EP project aims to bring together on-farm technology to enhance decision making, profitability and reduce risk. Stored moisture, yield potential and risk are 3 main focal points of the project. Within this Yield Prophet(R) is used to understand and demonstrate the factors that drive yield potential, the yield gap and risk at 8 locations across the Eyre Peninsula. The project is funded by the National Landcare Program.

The Yield Prophet reports for the 8 locations on EP generated on 13 October 2022 are available for download.

Please note:

  • Yeelanna: Emu canola was the actual variety sown, but had to use ‘Early canola’ to match the phenology (quick variety), but will not have the same yield potential as Emu.
  • Minnipa: sowed Ballista but we used Mace for the report (Ballista not an option in Yield Prophet)
  • Cockaleechie: sowed Vixen but we used Sunco for the report
  • We made the assumption that stubble load was 50% of harvest dry matter.

On the attached reports in the first graph, the blue line is the water limited yield potential, that is the maximum possible yield with the given water. The probability (Y axis), indicates the probability that you will achieve that yield. The green line indicates the yield potential given current nutrition (nitrogen). The gap between the green and blue line is the ‘yield gap’ or further required nitrogen to reach water limited yield potential. When talking of yield potential we are looking at water limited yield at the 50% probability.
