Using nitrogen applications to manage wheat canopy locations
Aims

To determine the response of wheat to different Flexi-N strategies at two seeding rates, i.e. canopy management.

Key messages
  • This site was unresponsive to N and there was no significant effect of either seed rate or N timing upon yield.
  • Crop vigour was poor through the season and this was most likely related to subsoil acidity and aluminium toxicity.
  • Plant testing confirmed adequate supply of nutrients.
