Two field experiments were carried out at EL-Serw Agricultural Station Dommiata Governorate North East Delta during the seasons of 2006//2007 and 2007/2008 to study the effect of foliar treatments with urea at concentration of (0,1%,2%) and GA₃ at concentration of (0,100,200ppm) on  yield and quality of sugar beet cv. Sultany. The important  results could  be summarized as follows: 1- Foliar application with urea at concentration of 1% and 2% significantly  increased root length, TSS% in  the first season , also increased root  diameter ,root fresh weight  and sucrose % in  the second season ,root and sugar yields in both seasons. 2-GA₃ at 200ppm gave the highest significant  results of root length  in  the first season ,root  diameter ,root fresh weight ,purity % in  the second season,also increased sucrose %,root and sugar yields in both seasons. 3-Interaction effect  between urea foliar solution and GA3 was significant on sucrose %,TSS%, ,root fresh weigh in  the second season and insignificant effect on root diameter ,root length,purity% and root and sugar yields in both seasons.
