Strawberry experiments with the University of Reading

The customer

The University of Reading has been at the forefront of UK higher education for nearly a century. The university is considered an expert on the subject of strawberry production as agriculture has always been one of its core subjects, propelling the institution to among the 10 most recognised centres for agricultural studies globally. The Soft Fruit Technology Group at the university has been around for more than a quarter of a century and its mandate is to provide robust research and expert advice in order to support industry needs.

Global strawberry production increased by 39.4% between 2008 and 2018, according to figures released by the Food and Agriculture Organization. Food Autonomy has joined forces with the University of Reading to help growers boost their yield while reducing their energy costs. The parties launched a research project in mid-2019 on the use of LED lighting for out-of-season glasshouse strawberry crops.

The expectations

The aim of the first research trial was to compare the growth, yield and quality of a commercial strawberry under four different LED spectral distributions and to compare the performance of the plants under LED lamps, high pressure sodium lamps (a widely used lamp in glasshouse production) and unlit controls.

One of the objectives of the re-run of the experiment – which ended in May 2020 - was to re-confirm the data of the first study and to gather information on heat-related aspects of the use of LEDs. A key focus of the treatment was to create a warmer environment as the use of HPS results in warmer temperature than the use of LEDs.

The solution

The Research lamps of Food Autonomy, which provide all-around spectral variations to fine-tune light settings and modify the light spectrum, were the perfect answer for gauging the spectral requirements of strawberries, said PhD student Winnie Swann. The lamps are used primarily for R&D purposes and the module is equipped with pure colour LED chips, which guarantee unlimited variations in terms of colours

Ours is by now a long-standing relationship and we expect to continue working together going forward.

The result

The findings of the first research project of the Soft Fruit Technology Group and Food Autonomy, under the leadership of Professor Paul Hadley and involving Research Fellow Dr Carrie-Anne Twitchen as well as PhD student Winnie Swann, showed that all the LED treatments produced higher average berry weights than the unlit and the high-pressure sodium (HPS) light treatment. The LED treatment also appears to have produced a more compact plant.

The parties are currently engaged in a third phase of research. Reading University and Food Autonomy are committed to further increasing their knowledge on the topic and supporting the industry by continuously carrying out market relevant experiments and research.
