Contributor Hart Field Site Group
Trial location(s) Site 5, Hart, SA
Plant growth regulators in wheat locations
Aims

To measure the effect of plant growth regulants and their interaction with nitrogen on wheat grain yield and quality, in the absence of lodging.

Key messages
  • Plant growth regulators had no significant impact on wheat grain yield.
  • The only grain quality parameter to be influenced by PGR or nitrogen application was grain protein.
