Prenjori trials - using Yield Prophet for tactical nitrogen responses locations
Aims
  • To use yield prophet to help determine rates of nitrogen to apply.
  • To determine the response to Flexi-N in wheat.
Key messages
  • Yield Prophet provided good background information to apply nitrogen during the season. Whilst the nitrogen applica-tion treatment based of Yield Prophet reports was the second highest yielding treatment it did provide a delayed spend on nitrogen. Treatment 4 had exactly the same nitrogen application rate but the timing was far early than treatment 7 (Yield Prophet guided treatment). This does prove that Yield Prophet can help growers to make less risky nitrogen de-cisions without sacrificing yield and grain quality. Obviously with the excellent finishing rainfall the highest nitrogen application was the highest yielding treatment.
  • This site was very responsive to Flexi-N and some very high yields were produced.
