Research findings into production methods for the popular Asian delicacy and meat substitute – jackfruit – will be discussed at today’s Carnarvon Research Station field day.
The Department of Primary Industries and Regional Development (DPIRD) trial is part of a Cooperative Research Centre for Developing Northern Australia (CRCNA) project spanning Queensland, the Northern Territory and Western Australia.
DPIRD researchers are finalising key findings from the three-year study, where Carnarvon presents unique challenges due to its environmental conditions, including extreme heat stress, light stress and wind.
Researchers examined trellising systems, planting densities, varieties and irrigation methods to maximise production potential.
They also looked at the use of a kaolin-clay spray to reduce sunburn.
DPIRD research scientist Melanie Ford said the project had informed how to effectively establish the crop in Carnarvon.
“We’ve examined the performance of a number of varieties, some already locally grown, and others sourced nationally, and have selected four varieties which we believe are well suited to growing conditions in Carnarvon,” Dr Ford said.
“As the locally adapted varieties have been here for some time, we are looking at genetic testing to determine their origin.”
Dr Ford said trellising did not appear to offer the benefits for Carnarvon that could potentially be reaped in other areas, as it reduced canopy cover making establishing plants more exposed to sunburn.
A kaolin clay spray used on the trees to reduce the effects of sunburn on the leaves proved to be effective during the establishment period of the trees.
The Demonstrating Next-Generation Resilient Orchard Production Systems for Tropical Crops project is led by the Queensland Department of Agriculture and Fisheries and involves the NT Department of Industry, Tourism and Trade, Manbulloo Limited, Aus-Ex Fruit, the NT Farmers Association and Growcom.
CRCNA Chair Sheriden Morris said this was a great example of the collaboration occurring across Northern Australia, aiding agricultural diversification and climate resilience.
“Project like this provide growers with sought after production management advice, as well as strategies to mitigate the risks associated with tropical cyclones and severe weather in the north,” Ms Morris said.
