Research

The Victorian and Tasmanian stubble project partners have been commissioned by GRDC to research cropping system components that are directly impact, or interact with, crop residue in a stubble retained system.

Field research is being carried across Victoria and Tasmania by BCG, SFS and ICC. Research reports are published on this website as they are released. Findings from 2014 and 2015 have now been uploaded. Anecdotal evidence and case studies that support research findings are being put together by VNTFA.

Information and research findings are being used as the basis for guidelines being developed for growers which will be released at stages throughout the project’s life.

Research projects and case studies will examine the interaction between stubble management and the following:

  1. Break crops and crop sequences
  2. Row spacing (for a range of likely crop yields)
  3. The desired stubble characteristics targeted for retained stubble systems (ie what sort of stubble needs to be produced by the harvest process?)
  4. Management of the harvest process to produce stubble with the required characteristics for retained stubble systems (ie machinery selection, set-up and operation)
  5. Tools and support to enable growers to understand likely returns to the farm businesses from investments in harvest machinery suitable for retained stubble systems
  6. Tools/technologies to manage stubble characteristics during fallow period
  7. Fallow management
  8. The selection, set-up and operation of seeding equipment
  9. Canola establishment
  10. Inter-row sowing
  11. Weed management
  12. Herbicide application including the interaction of pre-emergent herbicides with stubble
  13. Pest management
  14. Disease management
  15. Crop nutrition
  16. Stubble load and crop profitability
  17. Stubble cover, soil moisture conservation and prevention of erosion.
