Nitrogen x sulphur management trial in soft wheat locations
Aims

To assess the effect of sulphur on tiller numbers, grain yield and quality when combined with in-crop nitrogen.

Key messages
  • Early sulphur application supported higher tiller numbers although this did not translate into yield
  • Site was very responsive to at least 79kg nitrogen application.
  • An additional 50kg urea (23kg N), resulted in slightly higher protein readings.
  • Site was unresponsive to sulphur application.
  • Timing and splitting of in-crop fertilisation conferred no yield advantage • Good utilisation of applied N and S in spite of high rainfall year.
