Two field experiments were conducted at Sabahia Agric. Res. Station in Alexandria during 20021 2003 and 2003 I 2004 seasons. The objectives of this investigation was aimed to study the effect of some cultivars of sugar beet (Farida, Lados, and Athospoly) to some growth regulator treatments pndol acetic acid ( 1M ) and gibberellic acid ( GA 3) ] at different concentration ( control, 100 ppm 1M, 200 ppm GA 3, 300 ppm GA3,( 100 ppm 1M + 200 ppm GA3) and ( 100 ppm 1M + 300 ppm GA3) on root yield and its quality. A split plot design in four replications was used. The main finding could be summarized as follows:-
The results indicated that studied cultivars significantly differed in all studied characteristics under study exclusive root diameter and juice purity in both seasons as well as root weight in g I plant in the first season only were insignificantly affected. Farida cultivar surpassed Lados cultivar by 6.8 and 12.9 %, Athospoly cultivar by 5.5 and 9.3 % in root and sugar yield I fed, respectively over both seasons.
Regarding·· growth regulator treatments, the results indicated that all studied characters significantly affected in both seasons except juice purity in the first season only insignificantly affected. Foliar application of GA3 at 300 ppm significantly produced the highest root diameter, root length, root weight in g I plant, total soluble solids ( T.S.S. % ), sucrose, juice purity percentages as well as root and sugar yields I fed in both seasons. Root yield increased by 37.5 % and sugar yield by 66.6 % with spraying GA 3 at 300 ppm compared with the check treatment over both seasons.
Generally, it could be concluded that foliar application of GA 3 at 300 ppm with sown Farida cultivar maximized root and sugar yields per feddan.
