The research was carried out at Agricultural Scientific Research Center of Hama
in tow season 2010/2011. Aiming to evaluate the effect of nitrogen fertilization and
planting date on some Productive and Technological characters of sugar beet Mono
g
erm(Simper cultivar) and Multi germ (HM10 cultivar). Results showed an effect of
fertilization on productive and technological characters of sugar beet. Increasing the rate of
nitrogen fertilizer to 250kg N.ha¹ caused a significant increase in root yield and actual
sugar yield (12.88 , 12.15 ton . ha¹) respectively, but it badly affected the sugar content in
the roots, juice polarity and juice purity (14.68, 15.95, 80.45%) respectively. Mono germ
Simper was found significantly superior compared to Multi germ HM10 in root yield, Brix,
root sugar content and juice polarity. Results showed that planting date 1/11 was found
significantly superior compared to dates 1/10, 15/10 for root yield, Brix, juice purity,
actual sugar yield. In conclusion, Simper (Mono germ) was suitable in planting date 1/11 at
nitrogen level of (200-250kg N.ha¹).
The field experiment was conducted Al Raqqa research station, the General
Commission for Scientific Agriculture Research (GCSAR),. during the
2011/2012- growng season to compare quality traits of four monogerm fodder
beet varieties, i.e. Jamon, Sp
lendids, Starmon and Vermon. The experiment
was run in Autumn during November and in Winter during January.
Experiment was carried out in accordance with the split plot design with three
replications. The results of the comparison test T-Test preference fodder beet
cultivation in the autumn compared with winter, but by a small percentage in
most of the quality traits. The results also showed that the monogerm variety
Vermon was the best in most of the quality traits as compared with the other
varieties, followed by Starmon. It was recomended to cultivate fodder beet in
both autumn and winter under Al Raqqa conditions, but after conducting a
complementary researches concerns the other agricultural treatments as, lifting
time, plant spacing, fertilization …etc, and to test more monogerm and
multigerm varieties from different sources.
