An Investigation of varietal characteristics required for sustainable agriculture

This was a DEFRA funded research project carried out in collaboration with NIAB. The purpose of this study was to provide DEFRA with a review of our current understanding of variety characteristics that may be valuable in the context of existing and sustainable agricultural systems (e.g.'treated', 'untreated' and organic). This was combined with a review of physiological research that will allow these characters to be broken down into components that can be measured as part of a practical VCU (Value for Cultivation and Use) test.

By simultaneously eliminating components of these VCU tests that are inappropriate to the intended agricultural system, it is now possible to produce a more flexible VCU framework which ensures the selection of a wider variety of cultivars appropriate to the increasing diversity within farming.
