The yield potential of canola has been shown to be related to biomass production, and the objective of this trial is to evaluate the amount and timing of N application on hybrid canola to maximise biomass production and grain yield in our region. 
A randomised complete block design experiment was conducted at ‘Kayanaba’, Dandaragan in 2019 to assess various rates and timing of application of nitrogen on Hybrid canola. The soil type was a strong sandy loam soil with 23 mg/kg of N in the top 90cm prior to seeding, and a pH of 6.7 in the 0-10cm and 4.6 in the 30-50cm soil depth. The site was previously sown to barley in 2018.  
The site was sown dry on the 5th of May 2019 using knifepoints and press wheels to achieve a sowing depth of 2cm.
