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

ï‚· Selecting the best varieties is important to achieve Hyperyielding canola:
o HyTTec Trifecta (TT), 45Y28 RR and Xseed Condor (Truflex) were the highest yielding cultivars at both High and Low input.
ï‚· Extra inputs can increase yield potential in Hyperyielding canola:
o High input management (extra fungicide and nitrogen) increased grain yield (compared to Low Input) by an average of 0.74 t/ha.
ï‚· The best cultivars also had the strongest response to increasing inputs:
o The three highest yielding cultivars, HyTTec Trifecta, 45Y28 RR and Xseed Condor, increased yield by >0.9 t/ha with High Input management, compared with an average yield increase of 0.6 t/ha for the other six varieties.
o The increase in yield was mostly due to extra nitrogen in the High Input treatment.
ï‚· Increasing inputs (nitrogen and fungicide) increased final (maturity) biomass and increased harvest index.
ï‚· High yielding varieties can also have high oil concentration:
o Xseed Condor and HyTTec Trifecta had the highest oil concentration, increasing their potential gross income.
