Effect of Salt Stress on Growth, Productivity and Root Quality of Two Sugar Beet (Beta vulgaris L.) Cultivars

Understanding how different crops respond to salinity stress can provide valuable insights for managing salt-affected soils, ultimately leading to improved agricultural production and enhanced soil health. Therefore, this research objected the effects of five salinity concentrations (50 , 100, 150, 200 and 250 mM of NaCl), while the control treatment was irrigated using a normal water on growth, yield and quality of two sugar beet (Beta vulgaris L.) cultivars (‘Maged’ and Dreeman) . The results indicated that ‘Maged’ cultivar exhibited high significant mean values of growth, yield and quality characters compared with ‘Dreeman’cultivar, in addition the results showed significant variation between the salinity levels, whereas sugar beet can tolerant up to 250 mM NaCl of salinity and reducing stabiles yield, productivity and quality. The interaction among the two investigated cultivars and salinity levels affected significantly most studied characters. In general, it could be recommended that the sugar beet cultivar ‘Maged’ tolerated salinity up to 250 mM NaCl. Therefore, it is recommended that these sugar beet cultivars can be cultivated in new reclaimed soil as affected by salinity conditions and helps in decreased the salinization in arid area.
