Trial location(s) Lake Bolac, VIC
TwinN wheat locations
Aims

To evaluate whether TwinN could enable reductions in urea rates without loss of yield in wheat in the medium-high rainfall Victorian wheat region.

Key messages
  • The trial was designed to test the capacity of TwinN to enable reductions in nitrogen fertiliser applications.
  • The control treatments showed no statistical difference in yield between 0 and 50 kg/ha urea but a difference was seen between 50 kg and 100 kg/ha ureas.
  • Yield from TwinN plus 75 kg/ha urea was not statistically differenent from that from the 100 kg/ha urea.
  • No treatment effects were found in protein% or screenings%.
