Independent and technically reliable
The Cambridge University Potato Growers Research Association, known as CUPGRA, promotes the interchange of scientific research and field practice for innovative, sound commercial production of potatoes.
A charitable association, its members include potato growers, agronomists, packers, processors and other stakeholders in the supply-chain who value independent, high-quality research.

Unique, impartial, without being dependent upon commercial interests, and an enormously valuable source of data and advice which allows scientists to pursue projects without interference, neither financial nor intellectual. Thinking outside the box is what CUPGRA is very good at. Desiccating haulm to achieve good skin finish and, in particular, to combat black dot, takes far longer with varieties that produce large quantities of it.

I can’t remember what made us join, but never once have we considered leaving. Over and again trials have been undertaken, we’ve followed the results, improved production and reduced costs. For example, we have cut nitrogen and are still doing so. We haven’t used phosphate for years and overall our fertiliser use is very modest. We have the ultimate trust that we are being given the correct – and unbiased – information. The work is extremely rigorous and carried out under proper scientific terms.

The effort and time put into the research has been massive. A farmer attempting anything like that on a field scale is never going to be able to match it. Independent research is the lifeblood of successful farming, and that is what we get from the association, as well as good sensible data, which is not blighted by commercial interests. We particularly value the help we get in interpreting results. Work rates have improved and destoning and cultivation is quicker and easier with the consequent saving on costs and field operations.
