Abstract

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 GA₃at 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-GA₃at 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.
