This study was carried out on a 17 years Vineyard (Helwani, Betamooni. Cvs) when the study started. Two deficit irrigation treatments were studied (%88, 60%), in addition to the control (full irrigation), and each treatment included three replications. Drip irrigation technique was applied (one irrigation line for each tree line, and eight drippers for each tree). Fruit yield and sugar percentage were observed under different water treatments.

Research summary
أجريت هذه الدراسة على كرم بعمر 17 سنة مزروع بصنفين من العنب (حلواني وبيتموني) في محطة بحوث المختارية بمحافظة حمص. هدفت الدراسة إلى تقييم تأثير الري الناقص (80% و60% من الاحتياج المائي) مقارنة بالري الكامل (100%) على كمية الإنتاج ونسبة السكر في الثمار. استخدمت تقنية الري بالتنقيط مع ثلاث مكررات لكل معاملة. أظهرت النتائج أن معاملة الري الكامل (T100) أعطت أفضل كمية إنتاج بمتوسط 37820 كغ/هـ، بينما أعطت معاملة الري الناقص (T80) 34751 كغ/هـ. من حيث الوزن، أعطت معاملة الري الكامل أفضل وزن للعنقود وعدد حبات في العنقود، بينما كانت معاملة الري الناقص (T80) الأفضل في متوسط وزن الحبة. كما أظهرت معاملة الري الناقص (T80) أفضل نسبة للسكريات الكلية في الثمار، حيث بلغت 17.85% للصنف حلواني و18.51% للصنف بيتموني. أدى تطبيق الري الناقص (T80) إلى توفير في مياه الري بنسبة 11.35% وتحسين كفاءة استخدام المياه بوحدة إنتاجية بلغت 7.66 كغ/م² مقارنة بمعاملة الري الكامل (7.4 كغ/م²). توصي الدراسة باستخدام الري الناقص بنسبة 80% من الاحتياج المائي كأفضل معاملة لتحقيق توازن بين توفير المياه والحفاظ على جودة الإنتاج.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال تحسين كفاءة استخدام المياه في الزراعة، خاصة في المناطق التي تعاني من ندرة المياه. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، قد يكون من المفيد تضمين تحليل اقتصادي لتكلفة وفوائد تطبيق الري الناقص مقارنة بالري الكامل. ثانياً، لم تتناول الدراسة تأثير الري الناقص على جودة التربة على المدى الطويل، وهو جانب مهم يجب مراعاته. ثالثاً، قد يكون من الأفضل توسيع نطاق الدراسة لتشمل أصناف أخرى من العنب أو محاصيل أخرى لتعميم النتائج. وأخيراً، يمكن تحسين الدراسة بإجراء تجارب ميدانية في مناطق مختلفة لتقييم تأثير الظروف المناخية المتنوعة على النتائج.

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).
The present investigation was carried out at the Agricultural Scientific Research Center in Swieda to study the effect of deficit irrigation on the growth of four apple seedlings rootstocks genotypes and to estimate their ability to drought tolera nce particularly in light of the lack of water sources and no rain. Two irrigation levels: 100% (control) and 75% of water requirements were applied. The shoot length, leaves number, leaves area, the distribution of the roots in soil, the depth of irrigation water in the soil and the consumption of water in each level were measured. Results showed that irrigation with 75% of field capacity on studied genotypes caused reduction of shoots length, decline of leaves number and area and the depth of root comparing with the control. There were significant differences between studied genotypes in terms of vigor where the genotypes C and S2 were superior than A and B.
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.
A field experiment was carried out in Hout research station- Agriculture research center in Swaida – General Commission For Scientific Research Agricultural during the growing season of 2015-2016 to study the effect of different levels of deficit i rrigation with different levels of town refuse compost (TRC)on some morphological parameters and the productivity of lettuce and compare it with the common mineral fertilizers. The experiment was designed as a split block design with three levels of irrigation, each level has four fertilizing treatments and control with three replicates. The research has studied the plant height (H), the number of its leaves (N) ,the leaf area (LAL), the plant's leaves area (LAP), the leaves area index (LAI), in addition to the lettuce head's fresh weight and the total productivity of the planted area. The irrigation and fertilizing interaction results indicate to the obvious positive effect of the organic additions on the productivity parameters and the efficiency of deficit irrigation, and the significant superiority of T11 treatment in all of the measured parameters in compare with the other treatments with an increased final yield of %169 comparing with T15 and % 428 comparing with T35. The results also indicate to the possibility of saving %25 of the consumed amount of irrigation water by using TRC instead of mineral fertilizer , and reveal that the organicmineral combination achieved a better yield with percentages of ( 29- 44 – 53 )% comparing with single mineral fertilizer in the three studied irrigation levels (T1-T2-T3) respectively. These results give the farmer a wide range of possibilities to choose what suits his available productivity needs , and a clear idea about the expected yield according to the chosen treatment.
This study was conducted for two seasons (2010-2011) on Pistachio trees in Mourek area in Hama to identify the effect of number of supplemental irrigations on productivity characteristics.
