Afourer mandarin best practice canopy management (CT19002)

Key research provider: NSW Department of Primary Industries

What's it all about?

This investment is developing best practice canopy management techniques that will improve long-term yields and minimise alternate bearing in Afourer mandarins. Alternate bearing can be a significant issue for Afourer growers, causing high crop loads in one season followed by low crop loads the next, resulting in problems with fruit size and marketing. This project will ultimately develop a best practice manual that will provide practical solutions for growers to implement on-farm.

Specifically, the project is:

  • Building capacity through providing Afourer growers and industry development officers with the most up-to-date information (domestic and international) to improve production and canopy management techniques. The project team will conduct study tours within Australia and overseas to key growing regions such as Spain, California and South Africa. Findings from these study tours will then be implemented in trials on grower properties to test various solutions.

  • Conducting research into current grower management practices, including developing case studies based on data comparing yield, canopy management, nutrition, irrigation, plant spacing and general practices. The project team will establish up to 18 demonstration trials and four replicated trials on participating grower properties for three seasons to test new techniques identified by the project.

  • Seven replicated canopy management trials in total were implemented in Sunraysia and Riverina. Three mature tree and two young tree trials in Sunraysia and one young tree and one mature tree trial in the Riverina. 
  • Two field days occurred in Sunraysia providing local project participants an opportunity to see trials and discuss Afourer management issue. To learn more about the field days and other project progress including the trial treatments, read the December 2020 newsletter.
