Trial details

Researcher(s) Matthew Robertson (Pivot)
Year(s) 2003
Contributor Southern Farming Systems
Trial location(s) Gnarwarre, VIC
Site 6, Lake Bolac, VIC
Canola nutrition trials locations
Aims
  • Assess the effect of timing and application method on nitrogen efficacy in canola.
  • Assess a range of nitrogen products applied at sowing or bud visible stage in canola.
  • Quantify the effects of nitrification inhibitors on nitrogen products.
  • Investigate whether additional zinc has any effects on yield or quality of canola
Key messages

While the 2003 series of trials is largely inconclusive, they do highlight a number of take-home messages:
• Do not expect nutrients like nitrogen to work effectively where other essential nutrients like phosphorus are lacking.
• Site selection for nutrition trials is vital - conduct of trials on recently constructed beds is advised against. Ideally, trials will be conducted in situations where beds have been in a normal cropping rotation for at least 5 years.
• The jury is still out on best approach to N management for canola, but where reasonable profile N is present before sowing a crop, split applications are advisable to mitigate risk.
