To investigate the nitrogen rate and time of application response of canola varieties to yield and oil content of TT and RR hybrids in comparison with open-pollinated types to

• provide growers in lower rainfall environments with guidelines on optimal nitrogen rates and times of application to maximise grain and oil yields, and
• determine if the management of hybrid canola nutrition is different to that of open pollinated varieties due to different responses to N rates and timing.
