| Abstract | ||||
| In line with sustainable agriculture that depends on modern methods and new sources of non-traditional irrigation, a field experiment was conducted at a privet farm behind Cairo-Alexandria Desert Road, Giza, Egypt during two seasons to evaluate five sugar beet varieties under water salinity stress condition. The present work included 15 treatments; represent five sugar beet varieties: viz. Multi-germs (Amina, Farida, and Faten) and Mono-germs (Unners and Sharleston), in combinations with two salinity treatments (Magic-Sal (13% humic acid + 20% carboxylic acid) and Sal-Wax (50% carboxylic acid) components) compared to control application. Results indicated that salinity treatments help in early stages to increase the emergency percentage of sugar beet varieties under high salinity water stress. As compared to control treatment, salinity treatments significantly increase proline accumulation, leaf relative water content (LRWC %),and root yield, but, it caused a reduction in quality parameters (sucrose, purity, and extractable sugar percentages) in both seasons. On the other hand, variety (Amina) overpassed the other varieties under salinity water stress with respect to germination ratio, proline content, LRWC%,and root yield (ton/fed) in both seasons. While, Sharelston variety surpassed significantly the other studied varieties with respect to sucrose, purity, and extractable sugar percentage (ES%) in both seasons.The distribution of stomata density of leaf increased as salinity water stress level increased. Results also showed that five sugar beet varieties under two salinity treatments (Magic-Sal or Sal-Wax) had positive effects and increased stomata area, but stomata density and its index as well as stomata closure% decreased compared with non-use. | ||||
