Different sowing and topdressing nitrogen options in wheat locations
Aims

To assess the potential production benefits of various nhanced efficiency nitrogen fertilisers (EENFs) and liquid fertiliser strategies.

Key messages
  • The application of 40kg/ha at sowing resulted in significant yield responses from all products over the control where only starter fertiliser was applied.
  • Fertilisers banded at sowing generally resulted in higher yields and grain N recovery than top dress applications, while the inverse was true for grain protein levels.
  • Low grain protein levels (<10.5%) for all treatments and application timings generally indiates that yield was not optimised due to the limited nitrogen supply.
  • There were no significant responses found from the use of inhibitors in this trial.
