Successful canola establishment is key to delivering a profitable crop. Canola establishment is still a significant constraint to growers, with heavy and light soil types providing different challenges for growers. 

The target of this research is to provide growers with management options to increase the certainty of successful canola establishment, and reduce failures. This will become increasingly important as climate change is causing reduced growing season rainfall events. Consequently canola seeding conditions will range from very early seeding, in hot conditions, or quite late, in marginal moisture conditions.

Reducing risks of poor crop establishment in canola under marginal seedbed conditions offer prospects of increasing grower profitability. This may be achieved through an integrated approach that captures and leverages the interactions of genetics by environment by management (GxExM).

Combinations of novel approaches and technologies suitable for canola growing regions across Australia are more likely to deliver reliable canola establishment through additive effects, as opposed to on their own. The primary focus of the research is around critical temperature, moisture levels and seed depth. There will also be genetic innovation in long hypocotyl testing. Additional research may include secondary seed dormancy, precision seeding technologies, seed treatments, soil water repellence and soil surface crusting.

To evaluate and optimise combinations of GxExM components a range of activities including desktop analysis, glasshouse and field experiments coupled with modelling across Australia are all included in the research plans. Industry consultation and collaboration with current investment partners will ensure appropriate approaches and methodologies are deployed which deliver to growers in all three GRDC regions, and bespoke management recommendations for each target production environment.

This is a national project, the DPIRD lead is Jackie Bucat, and nationally led by Andrew Fletcher, from CSIRO. Other partners are NSW DPI and Eyre Peninsula Agricultural Group.
