Presentation of the experimental station

Located in St Pol de Léon, at the heart of Brittany’s vegetable and horticultural zone, the station conducts applied research programs in fresh vegetables, ornamental horticulture, and cultivated mushrooms. These programs aim to solve technical issues encountered in production or to respond to changes in consumption.


The Vézendoquet experimental station has been managed since 1982 by the Caté (Technical and Economic Action Committee), a professional union that has brought together vegetable and horticultural professional organizations in the Brittany region since 1965.

The governance is ensured by a Board of Directors composed of growers.

The President of Caté is Jean-Denis Crenn.

The Caté experimental station conducts applied research programs, notably for the Regional Chambers of Agriculture in Brittany, as well as for nationally recognized organizations such as Prince de Bretagne, SAVEOL, SOLARENN, Le potager de Jade, Kérisnel, Armor Végétal…

The applied research work has regional, national, and European scope.

Regarding cultivated mushrooms, the Caté experimental station conducts a national experimentation program on diversification species in collaboration with ANICC, a specialized structure in button mushroom cultivation.

Caté is a member of IRFEL, a national association that brings together 15 regional experimental stations in fruits and vegetables.

At the regional level

The Caté experimental station is a member of Phytopôle Bretagne and works more directly with nearly 2,500 vegetable and horticultural producers.

Dissemination of Results

The applied research work aims to be transferable to end users. The findings from the trials are disseminated to agricultural advisors.

Caté publishes a quarterly information magazine called ‘Aujourd’hui &Demain’, distributed in 1,700 copies across the vegetable zones in Brittany.

This bulletin is one of the dissemination channels for applied research results from Caté and its partner structures since 1966.
