Research in 2016 showed that nitrogen had a significant effect on crop growth and yield of canola; and the optimum application rate when targeting 4.0 t/ha was 200 kg N/ha. Tony Napier, Cynthia Podmore, Neroli Graham, Luke Gaynor and Deb Slinger NSW Department of Primary Industries IRRIGATED canola trials were conducted for a third season in 2016 as part of the Southern irrigated cereal and canola varieties achieving target yields project. The target yields project was instigated in response to irrigators identifying the potential to increase production of irrigated cropping systems. In 2014, the Grains Research and Development Corporation (GRDC) and NSW Department of Primary Industries (NSW DPI) established the $1.2 million co-funded project for three years to address the needs of the southern irrigation region.
