Abstract
Four field experiments were carried out in Ras Sudr Research Station, DRC
during 1999/2000 and 2000/2001 winter growing seasons to evaluate eight barley
varieties under two salinity levels of irrigation water (8000 and 11000 ppm) in
calcareous soil. Data of growth recorded at 80 days after sowing cleared that, raising
level of irrigation water salinity greatly decreased each of plant height, number of
tillers/plant, number of leaves /plant and leaf area/plant but, increased leaves dry
weighUplant. Also, at harvest, yield and yield ccmponents were decreased due to
raising level of irrigation water salinity.
Generally, results pointed to the relative growth vigor for ICARDA-1 and Beecher
barley CVS compared with the other barley varieties were tested under the two levels
of irrigation water salinity and followed by Giza 123 and Rihane 0.3. Results showed
the superiority of ICARDA-1 and. Beecher in yeild components except grain
numbers/spik, where Giza 123 was at par with ICARDA-1 and Beecher under both
levels of irrigation water salinity.
ICARDA(1) and Beecher were higher and more than the other barley varieties in
leaves chemical contents i.e. proline, Mg and S04 except chlorid. And these varieties
were more tolerance for salinity where KINa ratio was more than one compared with
the other barley varieties were tested under the same conditions.
