2022 | Topp B, Alam M, QDAF | Research report/Update
In May of 2022 QDAF hosted a virtual field walk showcasing the macadamia rootstock trial and phase II of the macadamia planting systems trial.
2021 | Searle C | Research report/Update
With the summer storm season upon us, growers are urged to manage risks and minimise the negative effects of unpredictable weather events. But when an orchard sustains storm damage, how do you prioritise the clean-up and give damaged trees the best chance of recovering? Dr Chris Searle provides triage guidance for young and established orchards following severe weather, as well as preventative measures to mitigate damage.
2019 | Wilkie J, Toegel H | Presentation
Presentation by QDAF horticulturist John Wilkie and honours student Hanna Tougel on pruning and competition in macadamia, which is part of the Small Tree High Productivity initiative. Includes an update on recent trials.
2019 | Toft B | Presentation
Presentation by Ben Toft (Small Tree High Productivity Initiative) on limb angle and canopy structure in macadamia orchards. Includes information on trellis limb bending trial at Bundaberg Research Station. Discussion about natural occurring limb angles, vegetative responses to limb bending, vegetative relationships with limb angle, flowering relationships with limb angle, productivity response to limb bending, productivity relationships with limb angle, and limb bending in macadamia.
2017 | Anon | Case Study
Bundaberg Sugar has four orchards in the Bundaberg region totalling 330 ha. In the last four years, it has increased production on its Koolboo macadamia orchard from 175 t in 2013 to 480 t in 2016. Last year’s result was significant in that it tipped production over 5.4 t NIS/ha and over 2 t SK/ha. Sean Cox describes his management strategies that are contributing to this production growth.
2017 | Commens R | Case Study
Phil and Nicki Primrose bought their already established orchard at Woodford Island in mid-2009, and started work on it in 2011. The orchard was run down – it had not been harvested for the previous three years and no orchard improvement works such as fertilising, pruning or composting had been done. They took the orchard from this state to being one of the highest producing orchards in NSW in the 2014 season. This case study describes the management decisions taken in rejuvenating the property.
2017 | Singh L | Case Study
As orchards have matured, the impact of canopy management on crop yield has become clear, with many growers in the throes of deciding whether they prune or don’t prune. The real decision to make, however, is when to prune?
2017 | Commens R | Case Study
Stewart and Salina Edmonds describe their approach to managing their Caniaba macadamia orchard.
2017 | Johnstone B, Bright J, Currey A | Case Study
An integrated orchard management (IOM) program being implemented on the Nicol family orchard in the Northern Rivers has borne fruit after just a year. In this article, orchard manager Bill Johnstone describes the key aspects of the IOM program.
2017 | Kaddatz B | Case Study
Brice Kaddatz travelled north to visit macadamia growers from Yeppoon to the Atherton Tablelands. His report reveals much activity on the part of a growing band of orchard owners who are trialling different cultural methods to identify those most suited to their situations, and are working to ensure their trees are managed to ensure sustainable production. Some orchards are also still recovering from the effects of Cyclone Marcia in 2015, which makes the progress these orchardists are making even more impressive.
