Partial Root Drying: A sustainable irrigation system for efficient water use without reducing yield
- 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 the
plant are always in contact with drying soil.
- This technique will be used to control excessive 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 fertilisation use
efficiency. We plan to develop a better physiological understanding of the
mechanisms controlling carbon allocation to fruits as a basis for developing
approaches to the optimisation of irrigation.
