Canola nitrogen trials

The Tactical Break Crop Agronomy project has many canola agronomy trials each year. A key research theme has been exploring how late nitrogen can be applied to canola. There have been 26 nitrogen trials from 2013 to 2016 and this page presents the list of locations and reports from these trials.

Canola nitrogen trial locations

The focus of the N series was to determine if timing of top-up N had an effect on the grain yield, oil and gross margin response of canola to N. In general we found that if some N was applied in the first eight weeks after sowing (WAS), top-up N could be applied at 12WAS in lower rainfall areas and up to 14-16WAS in higher rainfall areas and provide a similar N response to the same rate of N applied earlier.
