Water supplies are limited worldwide since water use has been growing at more than twice the rate of population increase in the last century, and the numbers of regions that are chronically short on water are increasing. Therefore the problems of water scarcity are mostly acute.
There is an urgent need to identify and improve effective irrigation management method under the condition of water scarcity. Partial rootzone drying irrigation (PRDI) is a potential water-saving irrigation method. Using special irrigation methods which save water usually lead to soil salinity problems, when leaching is not sufficient to remove soluble salts from the rooting zone. Several factors influence the soil salinity levels of irrigated land. Some of the factors are the irrigation method and the intensive use of water combined with high evaporation rates.
The main goal of this research is to investigate the effect of the partial rootzone drying irrigation (PRDI) on yields and other parameters, and to compare it to the conventional irrigation (CI) when applying the same amount of water in both irrigation methods. The influence of PRDI on soil salinity movement and distribution are investigated too.
