Trial details

Researcher(s) Vicky Rush (EldersVP)
Year(s) 2002
Contributor Southern Farming Systems
Trial location(s) Gnarwarre, VIC
Barley growth regulator trial locations
Aims
  • To determine the effect of growth regulators on plant height and lodging tendency.
  • To measure the effect of growth regulators on grain yield and grain quality.
Key messages
  • Growth regulators had no effect on reducing crop lodging, since crop lodging was not evident due to seasonal conditions and low soil nitrogen levels.
  • Some growth regulators had an effect on reducing plant height.
  • Growth regulators had no effect on barley yield or grain quality.
