نفذ هذا البحث في مركز البحوث العلمية الزراعية في الغاب في العروة الخريفية من الموسمين الزراعيين 2009-2010 و 2010-2011 وفق تصميم القطع المنشقة (Split-Plot) و بثلاثة مكررات. و هدف هذا البحث لدراسة أثر التسميد البوتاسي في الخصائص التكنولوجية و الإنتاجية لصنفين من الشوندر السكري (سوبريما، د.س 9004) في ظروف منطقة الغاب. حيث استخدمت أربعة مستويات من السماد البوتاسي (0, 120، 170، 220 كغ K2O/هـ). أظهرت نتائج هذا البحث أن إضافة السماد البوتاسي أدت إلى تحسن الخصائص التكنولوجية و الإنتاجية لمحصول الشوندر السكري و بشكل معنوي، حيث تم الحصول على أعلى نسبة سكر في الجذور (16.18%)، و أعلى إنتاجية من الجذور (83.02 طن/هـ)، و أعلى غلة من السكر الأبيض (11.65 طن/هـ) في المعاملة (170 كغ K2O/هـ).
This research was carried out at the Agricultural Scientific Research Center in AL-Gab during 2009-2010 and 2010-2011 seasons in fall. The experiment was laid according to split plot design with three replicates, to study the effect of potassium fertilization on the technological and productive properties of two varieties of sugar beet (Suprima, D.S. 9004) in AL-Gab area. Four levels of potassium fertilization (0-120-170-220 kg K2O/h) were used. The results showed that the addition of potassium fertilization significantly improved the qualitative and quantitative properties of sugar beet. The higher sucrose (%), yield of root (ton/h) and white sucrose (ton/h) were at the potassium level 170 Kg K2O/h which reached 16.18%, 83.02 ton/h and 11.65 ton/h respectively.

The study included the reality of marketing crop sugar beet in Syria in general, and
in al ghabb 's area , in particular, has shown results that the problems and difficulties of
marketing sugar beet back to the non-compliance of farmers date of Agr
iculture
appropriate and space devoted to the cultivation of the crop sugar beet and assessed by the
General Authority to manage and develop Al Ghabb's area, in addition to the failure of the
extension units in turn supply the deadline cards provide timely and sufficient quantities to
farmers as a result of the process control system of favoritism in the distribution of cards
supply extension units.
In addition to the low energy manufacturing to the sugar mill, and its inability to
absorb the quantities produced in excess of the agricultural plan, along with breakdowns
lab frequent result gave the mechanisms used in it, and the need for frequent maintenance,
and low efficiency of some sections of the lab, and the control system favoritism determine
the degree of sweetness, as shown by the results Search also "high production and
marketing costs for sugar beet crop and is higher than its price.
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).
It is well established that sugar content of sugar beet increases as the plant
reaches the biological maturity stage. This means that the sugar beet plant
must be left in the field to complete its growth. Farmers are usually concerned
with the hig
hest yield of sugar beet roots regardless of their content of sugar,
but sugar-processing companies are concerned mainly with the amount of
sugar extracted from a certain weight of roots, in addition to the purity of the
sugary juice.
Farmers normally receives the price of their sugar beat crop based on the
sugar content of the crop. Thus, in this type of farming, biological control is a
worldwide-procedure.
Biological maturity depends on ways of yield formation and a close control
of the mechanisms of forming yield components (no. of roots / unit area;
average root weigh; average sugar content) which require a detailed study of
the characters of the grown cultivar and the overall conditions of the growing
area.
Results showed that harvesting of sugar beet sown in fall season befor the
plant completes it’s growing cycle (in June) results in a big yield in addition to a
reduction in sugar content in the roots which inturn results in a big loss in the
national economy.
Results indicated that delaying date of harvest up to ١٨th of July markedly
increased root and sugar yield as well as sugar content in the beet roots.
Increasing nitrogen rate up to ٤٠٠ kg / ha resulted in a marked increase in root
and sugar yield / ha . On the other hand, sucrose content gradually decreased
with excess nitrogen. Higher plant density (more than ١٠٠,٠٠٠ plants /ha)
enforce for late harvesting in comparison with other densities for at least ١٠
days to obtain high yield of roots and sugar.
The study has shown that the apparent bulk density of soil increases with the increase
of compression and moisture during press. The maximum rate of increase in depth was 0 –
20 cm that amounted 0.38g/cm3 at compression by 257.44-kilopascal and moi
sture
average at compression by 19.03% (equal to 60% of the field capacity average of the soil)
in comparison with the non-existence of compression. In addition, the size of the pores
bigger than 50 microns decreased at the same above compression and above moisture in
depth of zero – 20 cm by 20.20%. The size of pores bigger than 10 microns decreased by
20.65% in comparison with the non-existence of compression. While it was noted that the
the maximum loss of root yield that amounted 17.52%, at compression by 257.44
kilopascal, and moisture 19.03%.
Cotton is considered as one of the most important crops grown in AL-Ghab plain and which distinguish by excessive requirements from mineral elements.The importance of this study comes in trying to increase the economic proceeds of cotton crop by guidance of using of fertilizers and keeping soil fertility
