نفذ البحث خلال الموسمين الزراعيين 2011 ــ 2012 لدراسة تأثير تسوية الأرض الزراعية بالليزر و الحراثة على ثلاثة أعماق ( 35, 25 ,10) سم عند ثلاثة برامج لمياه الري بفاصل (7 , 8 , 9 ) أيام و التداخل بينهم على إنتاجية القطن و وإدارة مياه الري و الجدوى الاقتصادية, أظهرت الدراسة النتائج الآتية: 1- حققت التسوية بالليزر زيادة معنوية بالإنتاج و توفيرا" معنويا" بكمية مياه الري مقارنة" بعدم التسوية و تفوقت على عدم التسوية بالجدوى الاقتصادية خلال موسمي البحث. 2- حقق عمقي الحراثة ( 25 و 35 ) سم زيادة معنوية في الإنتاجية مقارنة" مع العمق 10سم و كانا ذا جدوى اقتصادية أكثر من العمق 10 سم, في حين كانا أكثر استهلاكا" لمياه الري بالمقارنة مع العمق 10 سم. 3- حققت زيادة كمية مياه الري زيادة" معنوية بالإنتاج وصلت إلى 1441 كغ/هـ من القطن المحبوب و ذات ربح صافٍ أعلى بالمقارنة مع تقليل كمية مياه الري قدرت بـ 31360 ل.س/هـ. 4- حقق التداخل بين العوامل المدروسة تأثيرا "معنويا" في الصفات المدروسة و كانت أفضل النتائج عند التداخل بين ( عمق الحراثة 35 سم × تواتر الري 7 أيام × التسوية بالليزر ) خلال موسمي البحث.
The research was carried out during the growing seasons of 2011 and 2012 to study the effect of land leveling by laser, three tillage depths(01, 25 and 35cm) and three irrigation systems with 7, 8, and 9 day intervals, along with the interactive effect between them on the yield of cotton (C.V Aleppo-90), irrigation management and net grossing. The study showed the following results: 1- Land leveling by laser significantly increased the seed cotton yield, saved irrigation water, and made net grossing higher as compared to no-leveling by laser through the two seasons. 2- The two depths of tillage (25 and 35cm) significantly increased the seed cotton yield, increased the irrigation water amount, and made net grossing higher as compared to the depth of tillage (10cm).. 3- Increasing the irrigation water amount significantly increased the seed cotton yield which reached 1441KG/H, and achieved higher grossing which reached 31360 S.P/H as compared to the lower irrigation water amount. 4- The interactive effect between the factors of this experiment gave a significant positive difference. The best results were at (deep tillage 35cm × intervals 7 days × leveling by laser) through two seasons.

Predicting crop yield response to irrigation level is increasingly important to
optimize irrigation under limited available water and for enhancing
sustainability and profitable production. This study was carried out to evaluate
the performance of
CropWat model in predicting deficit irrigation effect on
cotton crop, and to explore some alternatives for cotton irrigation. Crop yield
and water use data were collected from a 3-yr (2007-2009) field experiment to
assess the response of drip-irrigated cotton to deficit irrigation (DI).
This study was carried out to compare the performance of the FAO
AquaCrop and CropWat models in simulating the effects of deficit irrigation on
cotton crop. The models were calibrated using data from the 2007 growing
season of a field study conduc
ted to assess deficit irrigation effects on cotton,
whereas the models were validated by comparing their outputs for yield and
water use (ETc) with the measured values of the two variables in the 2008 and
2009. The relationship between measured and predicted values of yield and
ETc revealed that the AquaCrop was better than CropWat in predicting water
stress impact on yield and ETc. The linear regression equation for AquaCrop
had a small intercept and its slope was very close to unity. The index of
agreement (d) was close to one for both models, except its value for ETc in the
2009 year. Both models could reproduce the general trend of the changes in soil
water content in the different irrigation levels. Accordingly, the use of
AquaCrop instead of CropWat should be encouraged for management and
planning of irrigation, since it is a practitioner type model keeps a good balance
between output accuracy and simplicity.
This experiment was conducted during ١٩٩٦-١٩٩٨ to ivestigate study the
effect of using different types of irrigation water on some soil properties and its
cotton, corn and wheat productivity under the agroclimatic conditions of Deir
Ezzor.
This study aimed to evaluate the effect of low-level laser therapy
(LLLT) on orthodontic treatment time reduction throughout leveling
and alignment stage.
We can conclude depending on this study results that LLLT is an
effective method for orthodontic archwire change acceleration and
consequently for reducing the orthodontic treatment time.
The experiments were carried out at Deir Ezzor research Center , Salou Research Station during the growing season 2008 and 2009 . The cotton variety Deir Ezzor 22 was grown and the soil was treated, one day before cultivation date.
