Monitoring and Managing Post-harvest Quality in Macadamia
2024 | Jones K | Fact Sheet
AMS’ recent MacGroups featured post-harvest management expert Kim Jones, Director of Cropwatch Independent Laboratories. The session provided participants with practical ways growers can retain nut quality on-farm. This resource summarises useful monitoring and management tips.
Post-harvest NIS assessment guide
2023 | Australian Macadamia Society | Manual/guide
This guide is designed to help you identify nut in shell defects and their causes. It also lists control measures most commonly used to help manage problems in the orchard that cause defects.
How on-farm handling can impact macadamia quality (Feb 2023 MacGroup)
2023 | Wallace H | Video
Do you have capacity to hold and dry nuts on farm if there are delays or difficulties within the delivery system this season? At the February 2023 AMS MacGroup, post-harvest specialist Prof. Helen Wallace (Griffith University) outlined what we know about brown centres, on-farm post-harvest handling, and importantly how post-harvest handling impacts quality defects.
Tree shakers
2021 | Australian Macadamia Society | Fact Sheet
While tree shaking technology was introduced into
tree crop industries like almonds in the 1960s, it
has only been used in macadamias in the last few
years. Part of the reason for this is that growers
believed that the machines could easily damage
tree trunks or roots and possibly increase trees
susceptibility to disease or even kill them through
ring barking.
Tree shaking technology has come a long way since it was
first developed. Today’s shakers are sophisticated, more
“gentle” machines fitted with sensors as well as padded and
compensating heads contributing to them being much less
likely to damage trees than in the past.
With several growers having recently bought new or used
shaker machines, and contractors in New South Wales and
Queensland providing tree shaking services, growers are
now looking to the benefits of incorporating the practice
into their harvesting and orchard management schedule.
Grower experiences with tree shaking
2021 | Australian Macadamia Society | Video
A growing number of macadamia orchard owners and managers are incorporating tree shakers into their harvest programs. As well as helping to speed up harvest, shakers are being used to improve orchard hygiene, decrease the harbour for pests and diseases, reduce harvest costs and allow after harvest operations to start sooner than normal.
In this video, 4 macadamia growers talk about their experiences with tree shaking, including when and why they started, types of tree shakers, the benefits and challenges, results, varieties, use of ethrel, tree shaking and irrigation, and tips for other growers.
Assessing crop loss (Updated April 2023)
2021 | Australian Macadamia Society | Fact Sheet
Understanding and quantifying in-field losses, evidence of which never makes it to the processor, is critical.
Maintaining quality after harvest
2020 | Jones K | Article
Post-harvest management is just as important as insect and disease control. Growers can suffer significant losses through poor post-harvest handling practices that allow mould, brown centres, germination or discolouration to increase during storage on-farm. An understanding of the biological and physical processes that affect nut quality is essential. This article summarises past research on maintaining quality after harvest.
Tree shaker improving the harvest season
2020 | Australian Macadamia Society | Research report/Update
Macadamia grower Chris Cook, from Arapala orchard on the NSW mid north coast, talks about his purchase of a Shockwave Monoboom tree shaker. Chris shares some valuable tips and advice for other growers thinking of purchasing a shaker for their orchard.
Macadamia physiology and nut quality (Video, Feb/March 2020 MacGroup)
2020 | Penter M | Video
South African expert Mark Penter has completed extensive research on South African orchards during challenging climatic seasons and led numerous research trials to improve on-farm practices which directly impact kernel quality and post-harvest efficiency.
Ethepon use in challenging environmental conditions (Video, Feb/March 2020 MacGroup)
2020 | Penter M | Video
South African expert Mark Penter discusses the current climate changes facing the macadamia industry and the implications for agriculture for more broadly.
