Objectif We plan to improve the efficiency of water use for Mediterranean agriculture through sustainable approaches via an investigation of the effects of partial root drying on the vegetative and reproductive growth of a range of fruit crops. Irrigation down one side of a row of plants allows soil drying around roots on the other side. If the wetting zone is alternated from one side of the row to the other then some roots of plants are always in contact with drying soil. This technique will be used to control vegetative vigour, save irrigation water and reduce fertiliser use without influencing fruit yield and quality. We will assess the possibility of adding low concentrations of fertilisers to irrigation water in this system to increase fertiliser use efficiency. We plan to develop a better physiological understanding of the mechanisms controlling carbon allocation to fruit as a basis for developing approaches to the optimisation of irrigation.1.
