Research Projects
Globally, climate change-induced warming is posing a major challenge to increasing crop yields in cropping systems including protected cropping systems. Research to improve heat tolerance in these systems have largely focused on leaf traits, in part due to limitation in techniques for investigating other plant parts.

Berries are highly pollinator-dependent crops, and while managed pollinators such as honey bees, are effective pollinators, the establishment of the Varroa mite has resulted in fewer honey bee colonies in the region and hence growers have reduced access to pollination services. Wild pollinators are also known to visit berry flowers and established research has now demonstrated their efficiency is often equivalent to the honey bee.

Global increase in night temperature is associated with significant crop yield losses. For vegetables, grains and fibre crops (including tomato, wheat, and cotton), yield reductions can be up to 3–10% per 1°C increase in night temperature. This project investigates how warm nights reduce crop yield and will identify traits that confer tolerance to warm nights.

Food waste is a global issue, as almost one third of food produced is lost before it is consumed (Ishangulyyev et al., 2019). Simultaneously, the resources such as water, energy, land and fuel, used in the food production supply chain are also wasted during this process. When discarded into landfill, both the plant biowaste and food waste impact the environment by the emission of greenhouse gases (Benyam et al., 2018). Fruits and vegetables contribute only 20% to the total food purchased, but they are responsible for half of the food waste (AUSVEG, 2013).
P2-029
The project aims to test and pilot fast detection procedures with the aim of giving growers a suite of options to test for the presence of the pathogen prior to disease being evident. The project also aims to test a range of commercially available control measures and create management recommendations.
P2-028
The project aims to explore rhizosphere microbiome engineering to manage Fusarium wilt of tomatoes, and to evaluate changes in the rhizosphere microbiome in response to application of bio-organic products. Firstly, the rhizosphere microbial community associated with healthy and fol-infected tomatoes in Western Australia will be assessed. This will identify core microbial taxa critical to plant health and to provide insights into managing the Fusarium wilt disease by modifying the core taxa. Field trials on the long-term contribution of three commercial bio-organic products will be conducted to assess their impact on tomato crop performance, yield, and the rhizosphere microbiome. The rhizosphere soils from the field trial sites will be used as ‘donor material’ for the microbiome engineering experiment.
P2-024
Crop production systems in large controlled environment facilities are traditionally high-input, resource and capital-intensive. Optimising input parameters is a major avenue for increasing yield and quality whilst reducing waste of precious resources. The aim of the project is to define the optimum CO2 levels for tomato production in controlled environments.
