Trial location(s) Site 22, Binnu, WA
Flexi-N scorch locations

To compare the effectiveness of various Flexi-N strategies and to determine the effect of leaf scorch on yield.

Key messages
  • There were no significant responses to Flexi-N. There was little scorch when Flexi- was applied on its own but there was severe scorch with the wetter (Superscharge).
  • Site variability meant the effects oof Scorch could not be quantified.
