Abstract
Two field experiments were carried out at Al-Ayat, Giza Governorate during 2012/2013 and 2013/2014 seasons to study the effect of seed treatments and weed control on yield and its components of four sugar beet varieties. The important results could be summarized as follow: Sugar beet varieties were significantly differed in root length in the 1st season, root diameter in the 2ndseason, root yield and sugar yield in both seasons. The highest root length (23.9 cm) and the highest values of root diameter (16 cm) were resulted from Farida sugar beet variety. While, the highest juice purity percentage (87.6%) and the highest sucrose percentage (19.8%) were resulted from Toro sugar beet variety (means of two seasons). Halawa variety attained the highest root and sugar yields (36.22 and 5.95 tons/fad.) respectively (means of two seasons). Regarding the influence of seed treatments, there were significant effects on root length in the 1st season and on sugar yield in the 2nd season. Concerning the effect of weed control, Goltex herbicide as a weed control recorded the best values of root length (21.2 cm), root diameter (15.1 cm), purity percentage (87.2 %), sucrose percentage (19.2 %) root and sugar yields (30.9 and 6.11 tons/fad.), respectively comparing with hand hoeing. Belong to the interaction effect between the studied factors; it was significant on root length and root yield in both seasons, purity percentage in the 1st season and sugar yield in the 2nd season. Using Goltex weed control method in combination with stimulated seed of Farida sugar beet variety attained the highest values of root length (25.3 cm) in the 1st season, root diameter (17.5 cm) and root yield (29.69 tons/fad.) in the 2nd season and sugar yield (7.62 and 5.95 tons/fad.) in both seasons respectively. In addition, using Goltex weed control method in combination with stimulated seed of Toro sugar beet variety attained the highest values of root length (21.4 cm) in the 2ndseason and purity percentage (91.8%) also sucrose percentage (20.9 %) in the 1st season.
