The Canola Agronomy Research in Western Australia bulletin presents a summary of research results from the DPIRD Tactical break crop agronomy project. It also includes research results from the CSIRO Achieving stable and high canola agronomy across the low, medium and high-rainfall areas of WA project. These projects are both supported by co-investment from the Grains Research and Development Corporation.
Key research themes addressed in the bulletin:
Pre-seeding
- Early sowing profitable in 2015 and 2016
- Optimum sowing window to maximise canola yield in Western Australia using simulation modelling
- Yield of different herbicide-tolerant canola varieties: are there any differences among TT, RR, Clearfield and conventional canola technologies?
- Hybrid versus open-pollinated TT canola: which one wins where?
- Later flowering canola for the high rainfall zone?
Seeding
- Optimum canola density
- Keep canola density over 20 plants/m2 to combat weeds
- Retaining canola seed
- Wide row spacing and precision seeding for the northern agricultural region
- Sow shallow with big seed for the best bet canola establishment
- When to reseed canola
Nutrition
- Timing of nitrogen for lower rainfall canola in Western Australia
- Nitrogen rates are more important than timings in high rainfall canola in Western Australia
- Critical nutrient levels for canola in WA
- Lower fertiliser inputs to canola in lower rainfall areas
In-crop
- Yield loss to aphids
- Herbicide tolerance of canola
- Grazing canola
- Direct heading canola - less shedding in PodGuard varieties
