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 moisture 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%.

Research summary
تتناول الدراسة تأثير انضغاط التربة عند مستويات مختلفة من الرطوبة على بعض الخواص الفيزيائية للتربة وإنتاجية الشوندر السكري في منطقة الغاب. أظهرت النتائج أن الكثافة الظاهرية للتربة تزداد مع زيادة الضغط والرطوبة، وكان التأثير الأكبر في العمق 0-20 سم. كما انخفض حجم المسامات الأكبر من 50 ميكروناً بشكل كبير مع زيادة الضغط، مما أثر سلباً على إنتاجية الشوندر السكري. تم تحديد الكثافة الظاهرية المثالية لإنتاجية الشوندر السكري عند 1.12 غ/سم3، وتجاوز القيمة الحدية 1.28 غ/سم3 يؤدي إلى انخفاض معنوي في الإنتاج. توصي الدراسة باستخدام آلات زراعية ذات أوزان قليلة وتقليل عدد مرات المرور في الحقل لتقليل انضغاط التربة.
Critical review
دراسة نقدية: تعتبر الدراسة شاملة ومفصلة حول تأثير انضغاط التربة على خصائصها الفيزيائية وإنتاجية الشوندر السكري. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين تجارب ميدانية إضافية في مناطق مختلفة لتأكيد النتائج وتعميمها. كما يمكن أن تكون الدراسة أكثر فائدة إذا تضمنت تحليلًا اقتصاديًا لتكاليف وفوائد استخدام الآلات الزراعية ذات الأوزان القليلة وتقليل عدد مرات المرور في الحقل. بالإضافة إلى ذلك، يمكن توسيع الدراسة لتشمل تأثيرات انضغاط التربة على محاصيل أخرى لتحقيق فهم أوسع لتأثيرات هذه الظاهرة.

The study was conducted on winter date (15th of Febraury), during 2015 and 2016 seasons, to study the effect of spraying calcium chloride CaCl2 concentrations (2, 4, and 6%), on the manufacture traits assigned in randomized completely block design (RCBD) with four replicates.
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).
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 fert ilization 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 was carried out at Soil Research Center in the province of Daraa during 2011 in order to study some physical and moisture characteristics for cinnamon soil, which occupies (48000 km²), equivalent to 26% of the area of the Syrian Arab Rep ublic and represents the cultivation of growing field crops with a rainfall ranges between 150- 300 mm. The results showed that the mechanical analysis for soil referred that its texture is clay with a good ability to retain water, the field capacity rated between (30-38.85)%. The studied soil has high value of available water (38.93mm) and useful water (25.69mm) in the surface layer. The highest value of permanent wilting point and hygroscopic moisture was reached in the final depth in studied profile soil, It was also distinguished a high total porosity ranged between 51.78 and 55.59% with a good air porosity amounted to 9.38 - 15.47 % in different depths and with the decline to 5.51 % in the depth 30 - 45cm.
