We investigate a range of innovative ways of using legumes to build soil fertility in glasshouses and polytunnels like using fast growing species of green manures that can be sown directly in the soil. We will evaluate the potential of a number of legume species.
In this case study we will set up field trials of Fava beans and French beans to assess the agronomic performance of heritage varieties in comparison to modern ones. The nutritional quality of the crops will be analysed. During the flowering period we will quantify visitation of the different varieties by pollinating insects and relate this to the production of floral volatile chemicals that may be responsible for attracting them and the quality of the resources that are provided in return.
