| 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. | ||
