UK: Strawberry yields doubled in controlled environments

Commercial strawberry yields have been doubled using Total Controlled Environmental Agriculture conditions, indicating a huge potential for utilizing plant material of leading everbearing varieties in new vertical farming practices, says crop research organization NIAB.

Using the variety Malling Champion, the highest yielding plants produced 3.2 kg of fruit, more than double the yield expected from typical everbearing plants in commercial production. The research was carried out at NIAB’s East Malling site in Kent, with the 3.0 kg peak being reached in May 2022.

Dr. Mark Else, NIAB’s Head of Crop Production Science at East Malling, commented, “This work has demonstrated that we can maintain growth and fruit production through the autumn, winter, and spring to increase total Class 1 yields. It demonstrates the huge yield potential that could be achieved by commercial growers if the optimum conditions are provided to the plants beyond the traditional growth period.”

The crop research organization NIAB has doubled commercial strawberry yields, using the variety Malling Champion under Total Controlled Environmental Agriculture conditions.

The overall Class 1 yield per plant over the 50 plants in the study was recorded at 2.4 kg, with the lowest yielding plant attaining 1.6 kg of fruit. This variation in yield under optimum growing conditions highlights the need for future research to ensure that the quality of initial planting material is consistently high to achieve the 3+ kg Class 1 yield from all plants.

Adam Whitehouse, Senior Breeder at NIAB who leads the East Malling Strawberry Breeding Club, said, “The ability to produce high yielding everbearing lines has been a major aim of the EMSBC program. It is especially pleasing to see the yield potential of Malling Champion, released in 2019, being realized in a controlled environment production system. The work carried out by NIAB will help us to understand how the environment can influence the genetics we are producing at East Malling and to identify the type of traits that will be optimal for developing varieties for growing systems of the future.”

NIAB is now in discussion with companies interested in vertical farming systems who would like to utilize the approaches and genetics developed at East Malling to harness new ways of achieving high yields and consistent berry production in commercial practice.
