Abstract
Irrigation management with nonconventional waters (saline water, reused
drainage-water, waste-water) require the identification of varieties which are
adapted to saline conditions. The study aims to identify the varieties which
combine high yield with the efficiency in using irrigation waters of different
qualities. Durum wheat, barley and winter wheat showed an ascendant curvilinear
relationship between grain yield and water use efficiency. The durum wheat
varieties showed large differences in grain yield that increased at increasing
salinity. Barley also showed large differences between the varieties, even more
pronounced than durum wheat but not increasing with salinity. Among the bread
wheat varieties only one variety was less suitable under saline conditions. The
durum wheat varieties (Cham.1 and Belikh.2) and the barley varieties (California
Mariout) and Melusine/A) present a combination of high yield and high water use
efficiency in a saline environment, whereas the bread wheat variety (Johara.14) is
less suitable under saline conditions than the other varieties. The varietal selection
combining high yield and high water use efficiency constitutes an important point
with respect to managing irrigation with saline waters.
Keywords: barley, durum wheat, bread wheat, water salinity, drought, water use
efficiency.
