Harnessing data and artificial intelligence to benefit rice industry

Charles Sturt University is working closely with industry partner SunRice to develop a model to predict rice quality at harvest time.

The rice harvest is underway and game-changing Charles Sturt University research is being put to the test to predict grain quality and provide timely information for processing.

Charles Sturt PhD student Allister Clarke from the Gulbali Institute of Agriculture, Water and Environment, is working with leading Australian food business SunRice and the Food Agility Cooperative Research Centre.

He said the research is focusing on one of the key measures of rice quality, whole grain yield (WGY), which represents the percentage of grains that remain un-broken during the milling process.

“Rice needs to be stored, dried and milled before the WGY can be appraised,” Mr Clarke said.

“That means that growers don’t know the pay grade of their crop until months after harvest and that the rice can’t be segregated for quality as it’s delivered.

“Our model can change that by giving processors and growers’ information about quality as the rice is delivered from the farm.”

Mr Clarke’s research uses satellite and climate data, historical rice production, harvest and milling information, along with machine learning algorithms to develop models to predict whole grain yield.

“This is the second year the model has been tested during rice harvest,” Mr Clarke said.

“The aim is to be able to provide information for SunRice to be able to predict the quality of the crop to manage storage and processing to maximise returns.

“But we also want to be able to provide information to the growers about how their management and harvest decisions impact the WGY.”

Mr Clarke said the research also demonstrates the benefits that can be gained in harnessing data across the value chain.

“This research wouldn’t have been possible without the decades of information that’s been captured from the paddock right through the milling process,” Mr Clarke said.

“I’m excited about the potential this area of research holds for other crops and industries in using the wealth of data across value chains to improve agricultural and food production.”

The CEO of SunRice’s Global Rice business unit, Belinda Tumbers, said the research project would deliver benefits for growers and SunRice, and was part of the industry’s broader research, development and extension efforts.

“The Australian rice industry is world class. We grow some of the highest quality Japonica-style varieties anywhere in the world while already using 50 per cent less water than the global average. SunRice takes that rice and transforms it into valued-added branded products at our facilities in the Riverina which are then marketed and sold in some 50 global markets.

“This position is underpinned by our research, development and extension into projects like this one, which are focused on productivity improvements for our growers on-farm, and throughout the entire supply chain.

“The Australian rice industry has just released a new five-year roadmap to guide the next phase of our research, development and extension efforts – focused on achieving an aspirational water productivity target of 1.5 tonnes of rice per megalitre by 2026.

“This new plan will assist us in maintaining the high quality of our rice varieties, while increasing focus on water-use efficiency. We are investing in four important areas of research, including optimising genetic improvement of our rice varieties, targeted agronomy and farming systems and investments in capacity improvement, as well as coordinated industry extension.”

The Gulbali Institute is a strategic investment by Charles Sturt to drive integrated research to optimise farming systems, enhance freshwater ecosystems and improve environmental management, to deliver benefits across Australia and globally.

The research comes as Charles Sturt University has been shortlisted for a share of $242.7 million in federal government funding under the Australian Government’s Trailblazer Universities Program.

The University’s ‘Reshaping Australian Manufacturing: Food and Beverage Commercialisation Hub’ project would assist with the national interest of supporting Australia’s economic recovery from the COVID-19 pandemic.

Outcomes of the Program’s selection process will be announced in late March.
