High Yielding Cereals and Canola – With a Good Start to the Season, What Management Practices Still Need to Be Considered?
The take home messages from this GRDC funded research are below. Please access the full paper via the link below for methodology, references, acknowledgements and discussion.
- To develop a nitrogen topdressing strategy you need to have a target yield and get the timing right.
- Allow approximately 40kg N/ha for every tonne of wheat grain yield and 75kg N/ha for every tonne of canola grain yield.
- Stripe rust in wheat and sclerotinia in canola are significant diseases and growers will need to consider an appropriate fungicide strategy.
