Welcome to the

AHDB Horticulture and Potatoes archive website

Hosted by the Agriculture and Horticulture Development Board (AHDB)

Following levy payers’ votes in 2021 on the future of the statutory levy, AHDB activity in the horticulture and potatoes sectors was wound down.

This website hosts the important legacy of technical and historic market information produced from many previous years of levy investment.  Here you will find an archive of information, guides, reports, resources, tools and data collated from the work funded by the horticulture and potato levies.  This includes projects that complete in 2024 which were continued to completion rather than lose the value of levy already invested in this work. 

You can access cross-sector crop information, that continues to be updated by AHDB Cereals & Oilseeds, or find resources from the AHDB livestock sectors, by visiting the main AHDB website.

Navigating this site

This site includes crop and subject themed lists of resources from the horticulture and potatoes home pages providing access to content through browsing by topic. 

Search functions on the Knowledge library or Research reports pages can also help find resources.  The search function works best with short and unique search terms.  Note that search results appear in order of upload rather than chronological order of activity or by how well they match the search term.

Winding down levy funded horticulture and potatoes activity

Some of the key services previously delivered through levy funding have been taken on by other organisations through a robust transfer process endorsed by Defra.  These include:-

For Horticulture:

For Potatoes:  

The Extended Authorisation for Minor Use (EAMUs) and Emergency Authorisation (EA) service.
