| Abstract: | Partial Rootzone Irrigation (PRI) is a novel irrigaing technique which improves water use efficiency when the production does not decrease. The technique requires that about half of the root system is always maintained in a dry or drying condition while the other half of the root system is irrigated. The wetted and dried parts of the root system are alternated after a period of time. The produce and physiological basis of PRI are discussed in this article. The future and problems of PRI in fruit trees culture are also analyzed. |
