A field experiment was carried out at Kom-Ombo Agricultural research Station Farm, Aswan Governorate, during 2019-2020 and 2020-2021 seasons to study the effect of sowing dates on growth, technological and yield traits of some sugar beet varieties under Kom Ombo conditions. Randomized complete locks design (RCBD) using strip plot arrangement with three replications were used. Planting dates (30th September, October 15th and 30th October) were allocated horizontally while, sugar beet cultivars of multi-germ (Betamax, Cleopatra and Tarbelli) were allocated vertically. The results indicated that the tested planting date had a significant effect on Root length (cm), Root diameter (cm), Root weight (kg), Sucrose percentage (%), purity percentage (%), Root yield (ton fed.-1) and Sugar yield (ton fed.-1) in both seasons and sodium percentage in the first season only. Furthermore, the tested genotypes had a significant effect on most studied traits in both seasons. In additions, the obtained data reveal that the interaction between planting date and sugar beet cultivars had a significant effect on sugar yield/fed. Trait in the two growing seasons. Planted sugar beet cultivar Tarbelli on October 15 achieved the maximum average values of sugar yield/fed. Which were 4.733 and 4.995 ton/fed. In the first and second seasons, respectively. On the contrary, the minimum average values of sugar yield/fed. Which were 1. 761 and 1.679 ton/fed. Were recorded from planted sugar beet cultivar Betamax on September 30 in the two respective seasons
