Water shortage in dry and semi-arid regions is a major agricultural challenge. This study investigated the performance of ten imported monogerm sugar beet varieties under continuous deficiency irrigation using a drip system on a private farm in the Wadi El-Natrun region, El-Beheira Governorate, Egypt, during two growing seasons, 2021/2022 and 2022/2023. The study utilized a novel method, a crossbar graph, to effectively visualize statistical data. The results showed significant interaction effects between sugar beet varieties and water deficit levels for all traits, indicating varying responses of the varieties to different levels of drought stress (75% and 55%). Drought stress levels (75% and 55%) had an adverse effect on the root yield of the ten varieties of sugar beet that were investigated. The exploratory factor analysis was applied to investigate and describe the relationship between ten different varieties of sugar beet and water stress treatments. Varieties Symbol, Stikhiyn, Volua, and Klara were characterized as moderate and tolerant with high performance, and they received the highest score in factor analysis. These varieties are recommended for cultivation under moderate and severe stress conditions. Factor analysis scores can be used as selection criteria for sugar beet varieties.
