Trial details

Researcher(s) Vicky Rush (EldersVP)
Year(s) 2002
Contributor Southern Farming Systems
Trial location(s) Lake Bolac, VIC
Barley growth regulator trial locations
Aims
  • To evaluate the ability of two different growth regulators over a range of rates and timings to reduce crop height, and therefore reduce the problem of lodging in barley.
  • To assess the potential yield and or protein variation following a single application of growth regulators. 
     
Key messages
  • The Ethrel @ 500ml and 750 ml @ flag leaf emergence produced the shortest crops, and therefore in broad acre situations this product may be the most effective at reducing crop height and preventing lodging. 
  • For further conclusions plese see the attached trial repor.t
