Research Officer Raj Malik in Gibson’s Nitrogen trial

Timing of nitrogen for canola grown in the high rainfall areas of WA, Gibson 2014 trial report

29 January 2016

Previous experience with canola has found there is no yield penalty if nitrogen is applied within eight weeks of sowing and most farmers aim to apply nitrogen within this timeframe.
