The project objective is to validate and extend previous agronomic and management research on how to successfully establish canola in the low rainfall zones of WA, as well as including feedback on what has/has not worked for growers through a series of field trial demonstrations and extension. By the conclusion of the project in March 2024, 60% of canola growers in the low rainfall zones of the Western Region will have access to the agronomic knowledge to improve the establishment and germination rates of canola.
Specifically, the project aims to:
1) Provide trial data and visual evidence of treatments that maximize canola establishment
2) Evaluate the ease of implementation of the treatments
3) Discuss and assess possible limitations to grower operation.
1. The placement of the seed relative to soil moisture and soil temperature conditions at sowing during 2022 and 2023 seasons had the largest influence on canola establishment across the low rainfall zones of WA. Delaying sowing to avoid exposing the canola seed and seedlings to high temperatures and placing the seed shallow in the soil profile above soil moisture in North Mallee (2023), Merredin (2022), Morawa (2022 and 2022), and Yuna (2023) maximised canola establishment, with a follow up rainfall event.
2. Grading open pollinated seed to above 1.8 mm was shown to improve canola establishment on a sandy soil type in North Mallee (2023), however, did not influence canola establishment in Merredin (2022) or Holt Rock (2023) on heavier soil types where soil moisture was present at seeding.
3. Fertilizer placement was shown to influence canola establishment at Cunderdin with the increased separation UAN below the seed associated with improved establishment.
4. The use of 25 cm row spacing (compared to 75 cm spacing) maximised canola establishment rates at Southern Cross.
5. The addition of SACOA SE14 soil wetter did not significantly influence canola establishment in any of the nine trials in which it was tested. However, good soil moisture was present at sowing for majority of the trials and subsequently the influence of soil wetters on canola establishment requires further research in varying seasons.
6. Besides the two trials at Yuna in 2023, none of the trials experienced a dry season start for seeding. Further canola establishment research is required to better understand how to avoid large canola establishment failures in unfavourably dry sowing conditions.
