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.

We hugely value the research CUPGRA does on behalf of its members. A huge database of rigorously undertaken, statistically proven trials, and a fabulous resource in the reference crop. Without this, growing and understanding our crops would be much harder.

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.
