To determine the response to increased crop inputs (fungicide and nitrogen) of a range of spring canola variety types.

ï‚· 45Y95 CL was the standout variety in this trial with a mean yield (across treatments) of 6.43t/ha. This was 78% higher yielding than the open pollinated ATR Wahoo.
ï‚· 45Y95 CL grew very high biomass (18.65 t/ha) and had a high harvest index (0.36). It is rare to have such a high conversion of biomass to grain (HI) at such a high biomass level and is a fundamental driver of achieving hyper yields.
ï‚· 45Y95 CL had a high number of seeds per pod as well as a high number of pods/m². This compares to ATR Wahoo which had a high number of seeds/pod but a low number of pods/m²; and Condor TF which had a high number of pods/m², but a relatively low number of seeds/pod.
ï‚· The High Input Management was higher yielding than both the Low and Medium Input management. The yield increased compared to Medium Input which suggests that this was driven by disease control; however it was difficult to ascertain which disease was causing yield loss. Fungicide reduced disease levels, but most diseases were at a low level including
sclerotinia.
ï‚· The RR/Truflex cultivars 45Y28 RR and Condor TF had the highest oil concentration with 48.8 and 48.3% respectively.
ï‚· Protein averaged 20.3%, meaning that 32.4kg/ha N was harvested per tonne of grain harvested.
ï‚· There was no effect of management on any of the grain quality parameters.
