| Abstract | ||
| In order to reduce the effects of salinity and increase land productivity, multiple strategies should be used in salt-affected soils. In two consecutive seasons, the study was conducted in the 2022/23 and 2023/24 seasons at a private farm in Sinnuris, located at latitude 29°17 N and longitude 30°53' E, Fayoum Governorate, Egypt. The randomized complete block design (RCBD) in a split-plot arrangement in three replications. The results demonstrated that spraying sugar beet varieties with 150 mg/l of nano-zinc during both seasons significantly increased the percentages of total phenol, total chlorophyll, and relative growth rate, as well as root diameter, root length, and root fresh weight/plant. Also, sucrose, extractable sugar, root, and sugar yield/fed. Nano-zinc levels had no discernible marked impact on sodium content in both seasons. In order to increase root and sugar yields under saline soil conditions, planting a multi-germ variety, Estora-KWS, and spraying it with 150 mg/l of nano-zinc can be recommended. Estora-KWS and Marwa-KWS multi-germ varieties outperformed all other tested varieties in both seasons, and recorded the highest mean values of root and sugar yields/fed. There was a strong and positive correlation between root yield/fed and both root diameter and weight. Path coefficient analysis, which compares relationship-based traits, was shown to be reliable and understandable in determining which traits are most helpful in selecting a tolerant sugar beet variety to grow in saline soils. | ||
