To study the spring culture possibility of sugar beet cultivars in Ahvaz climatic conditions, this experiment was execute in split plots based on complete randomized design in 2000-2001 agronomic year, using three factors included date of sowing (Dec. 21, and Feb. 8th) as main plots, sowing method (direct sowing and transplanting) as sub plots and cultivars (BR1, Monodoro and Rassoul) as sub plots at Agricultural Faculty of Shahid Chamran University of Ahvaz. The second date of sowing was synchronous with transplanting of the first sowing date. Final crop harvesting for both sowing date was in July 10. Date of sowing had a high effect on root yield. Root yield in the first date of sowing was significantly more than the second date of sowing. In each sampling compared to previous sampling, root sugar content, root sugar yield and the root yield increased. Different sowing methods in synchronous date of sowing had not significant effect on root yield (p≤0.05). However, root sugar content in direct sowing was significantly more than transplanting method. In the second date of sowing, sugar content was significantly more than the first date of sowing (p≤0.05) and Monodoro variety had the most root sugar content (10.1%) and the lowest impurities. The results showed that performing spring culture of sugar beet could obtain equivalent white sugar yield with autumn sugar beet culture in Ahvaz climatic conditions.
