Nitrogen management of hybrid and open-pollinated canola in the WA low rainfall mallee

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: 1. Provide growers in lower rainfall environments with guidelines on optimal nitrogen rates and times of application to maximise grain and oil yields. 2. 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.
