To assist growers with variety, nitrogen management and sowing date decisions to maximise irrigated canola yield potential.
• Nuseed Diamond achieved 5 t/ha grain yield from early sowing (watered for germination on 12 April).
• The high yield of Nuseed Diamond was due to its high biomass accumulation and high harvest index. ATR BonitoA was the lowest yielding variety, largely because it accumulated less biomass than hybrid non-TT varieties.
• Split nitrogen application resulted in higher grain yield than all nitrogen applied at sowing or all nitrogen
delayed to the 8-leaf stage.
Due to the wet conditions in 2016, only a small amount of irrigation was required. Three separate applications of 15 mm were made through a lateral irrigator in April to ensure timely crop establishment, with no further irrigation for the rest of the season.

Plant Breeders’ Rights (PBR)
Some crop varieties used in research trials may be covered by Plant Breeders' Rights (PBR). Users should confirm PBR status of relevant varieties by searching the IP Australia PBR database, http://pericles.ipaustralia.gov.au/pbr_db/ or Variety Central (http://varietycentral.com.au/) and contacting variety owners for further information if required. Where possible, varieties have been listed according to their registered PBR name, although OFT cannot and does not guarantee that the information is accurate or complete.
