Holistic management the key to Koolboo production

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.

Two different approaches to canopy management (row removal and pruning) both improve yield

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?

Northern orchard highlights

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.

Abandoned orchard becomes one of NSW’s top producers

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.
