BBRO Research

Our sugar beet research programme covers 2 areas of activity; crop production and crop protection.

Our full research programme currently consists of over 20 projects, some of which our delivered solely in-house but where possible we work in collaboration with other research partners. This increases the knowledge and expertise available, links us to other work and ensures increased return on our investment. The work within each pillar varies dependent on which issues have most importance or urgency to the industry.  


Crop protection is a key component for a successful and profitable sugar beet crop. Today, growers have a range of tools, technologies and elite varieties, to tackle and limit the ever increasing threats from pests, diseases and weeds. However, as climate change and environmental pressures build we have to look at new approaches to protecting the sugar beet crop.

Crop Stability is focused on delivering a clean, consistent and healthy crop which will maximize the yield potential from the genetics and growing environment.  We know the potential of the existing genetics and aim to close the current gap between actual and potential yield. The need to ensure we have alternative strategies for the loss of active ingredients and the impact of government legislation changes such as neonicotinoid loss are paramount to the success of the crop.

Crop production focuses on soil management and crop establishment.

The crop production research programme is targeted at areas where we believe there is the greatest potential for development.  

The programme focuses on closing the yield gap between the commercial crop and the variety trials.  Whilst improved genetics have had high impact there is a need to strengthen our understanding in other key areas such as:

  • soil management
  • early crop rooting and canopy development
  • how the crop is influenced by environmental relationships; water, nutrients, soil and temperature.
