Trial details

Researcher(s) Vicky Rush (Elders VP)
Year(s) 2003
Contributor Southern Farming Systems
Trial location(s) Site 6, Lake Bolac, VIC
Canola growth regulator trial locations
  • To assess the effect of two different growth regulators over a range of rates on crop height and lodging in canola.
  • To assess the effect of growth regulators on grain yield and oil content.
Key messages

The physical height difference between the treatments was very small and unable to be measured. None of the plots in the trial lodged.
None of the growth regulator treatments in the trial significantly increased or decreased the yield or oil content of the canola compared to the control treatment.
