The research was conducted on hybrid Squash (Nancy F1) at Tishreen University in the growing season of spring 2013 in order to study the effect of ground covering and low tunnels on the early production of squash. The study consisted of four experimental treatments: the control (without covering) and three covering treatments (ground covering using black mulch, ground covering with a low plastic tunnel, and a low plastic tunnel without ground covering). The completely randomized design was used with three replications per treatment and ten plants per replication. The results showed that the covering with a low plastic tunnel was superior to other treatments, resulting in a clear increase in female flowers, the ratio of female flowers to the total flowers, fruit number, and plant production. The results also showed a strong positive correlation between the plant production and the number of female flowers (r=0.999), the number of fruit per plant (r=0.999), the ratio of female flowers to the total flowers (r=0.990) and the total number of flowers (0.995). The correlation with male flowers was however negative (r=-0.954).

Research summary
تناولت الدراسة التي أجراها الباحثون في مشتل جامعة تشرين تأثير التغطية الأرضية بالبلاستيك الأسود والأنفاق المنخفضة على الإنتاج المبكر لمحصول الكوسا (الهجين Nancy F1) خلال الموسم الزراعي الربيعي لعام 2013. تضمنت التجربة أربع معاملات: شاهد بدون تغطية، تغطية أرضية بالبلاستيك الأسود، تغطية أرضية بالبلاستيك الأسود مع نفق بلاستيكي منخفض، ونفق بلاستيكي منخفض بدون تغطية أرضية. أظهرت النتائج أن التغطية بالأنفاق البلاستيكية المنخفضة تفوقت على باقي المعاملات، حيث أدت إلى زيادة واضحة في عدد الأزهار المؤنثة، نسبة الأزهار المؤنثة إلى الكلية، عدد الثمار على النبات، إنتاج النبات، وإنتاجية وحدة المساحة. كما بينت النتائج وجود علاقة ارتباط إيجابية قوية بين إنتاج النبات وكل من عدد الأزهار المؤنثة، عدد الثمار على النبات، ونسبة الأزهار المؤنثة إلى الكلية، بينما كانت العلاقة سلبية مع عدد الأزهار المذكرة. بالإضافة إلى ذلك، أظهرت الدراسة أن استخدام التغطية الأرضية والأنفاق المنخفضة يزيد من الكفاءة الاقتصادية للإنتاج من خلال زيادة الربح الصافي ومعامل الربحية مقارنة بالشاهد.
Critical review
دراسة نقدية: على الرغم من أن الدراسة قدمت نتائج مهمة حول تأثير التغطية الأرضية والأنفاق المنخفضة على إنتاجية الكوسا، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الممكن توسيع نطاق الدراسة ليشمل مواسم زراعية مختلفة أو أنواع أخرى من الخضروات لتحسين تعميم النتائج. ثانياً، لم تتناول الدراسة بشكل كافٍ تأثير التغطية على جودة الثمار من حيث الطعم أو القيمة الغذائية. ثالثاً، كان من الممكن تضمين تحليل اقتصادي أكثر تفصيلاً يأخذ في الاعتبار تكاليف الصيانة والإدارة على المدى الطويل. وأخيراً، كان من الممكن استخدام تقنيات تحليل بيانات أكثر تقدماً لتحليل النتائج بشكل أعمق.

Tunnels are usually considered as important and costly constructions and therefore it is very necessary to estimate their performance and analyze their structural behavior to maintain their safety in order to ensure their reliability and performan ce during their hypothetical life. In this issue we reviewed the situation of Syrian railway tunnels on Aleppo – Lattakia axis from the field observations which show that these tunnel linings are cracked. The numerical method, which is known as Distinct Element Method, was used in the analysis of cracked lining. This method performs modeling of discontinuous systems. We focused in this study on the concrete type through elasticity modulus and lining thickness. The result analysis shows that the effects of cracks modify the distribution of stresses and displacements in the lining. This modification is related to concrete elasticity modulus and mechanical crack characteristics.
This study was conducted at Research Altyba station where belongs GCSAR during 2007-2008. by using nine parental lines and their 36 F1 hybrids, were obtained from 9x9 half diallel design. The study included stem, earliness and yield component char acters, in order to estimate of hetrerosis compare to the mid parents, the better parent and to the standard hybrid, and determine the superior hybrids advantage to invest in agricultural production and benefit from as well as in breeding program development yield of squash. Heterosis over mid parent was evident in all yield components, The hybrid (IL3XIL6) exhibited (16.89 ، 57.57%) respectively for the ratio pistilate flower % and fruit number per plant, negative heterobeltiosis (-13.71%) was recorded by the hybrid (IL3XIL8)for the number of nodes to first flower, While the hybrid (IL3XIL5) showed maximum positive and significant heterobeltiosis (13.06 %) for ratio pistilate flower%, and the hybrid (IL3XIL6) for fruit number per plant (59.47 %) Whereas the results showed that, four hybrids had positive and high significant standard heterosis for plant yield, the hybrid (IL6xIL7) and (IL3XIL6) had maximum value (32.38, 28.68% ) respectively
This study was conducted at the vegetable field of department of horticulture and landscape design, college of agriculture and forestry ,Mosul university, during spring of 2007 and 2008, to study the effect of times and levels of nitrogen fertiliz ation on some characters vegetative growth, flowering ,and yield of summer squash .Result indicated that, the time of nitrogen fertilization at the stage of fruit-set caused a significant increased in the leaf number /plant ,length of the plant and the fresh weight/plant. While the time of nitrogen fertilization wasn't affected significantly the total yield. The level at 320 kg.N/ha caused a significant increase of the characters vegetative growth and total yield. Also result revealed that, the interaction between the stage at fruit set and nitrogen fertilization at 320 kg.N/ha led to increase the total yield .The yield was found to positively correlation with the plant length ,fresh and dry weights of plant, leaf area, fruit weight, male and female flowers, and the sex ratio.
In this research, nine inbreed lines of squash (Cucurbita pepo, L) have been studied during 2007-2008 seasons. The study contains plant phonological phases, and the most important morphological and productivity characteristics related to fruit yie ld to evaluate the characteristics of every line and identify the economical lines to use it in the breeding programs. The study showed genetic variation between the groups for some important economic characteristics as (the number of fruits per plant, percentage of female flowers, yield per plant, stem long and number of nodes till the first female flower). The study also showed that the inbreed lines of squash is a rich source of variation and can be use in a breeding program to product squash hybrid. The results appeared also the positive correlation between the productivity and some important economic characteristics, such as percentage of female flowers (r=0.871**), the number of fruits per plant (r=0.976**). Whereas negative correlation with the nodes till he first female flower (r=- 0.494) and internodes long (r=- 0.447). Using cluster analysis, the inbreed lines were classified into 2 distinct classes A and B, Class A contained seven inbreed wreathe class B contained Tow inbreed lines.
Allelopathy uses, as target plants, the cultivated species that are sometimes considered useful for comparative analysis, but do not naturally co-exist with the donor species (Reigosa et al., 2013) . Therefore, the weed common purslane (portulaca ole racea) (Portulacaceae) was selected as a target in addition to alfalfa (Medicago sativa) (Fabaceae) to compare with it. Two worldwide distribution weeds: sterile oat (Avena sterilis), and Aleppo grass (Sorghum halepense) (Poaceae) were chosen as donor plants, Water extracts of donor plants were prepared, 2%,4%,8% concentrations were used and distilled water was used for control. Seed germination and early seedling growth of target plants were studied in petri dishes. Lengths of seedlings were measured, after that, following indicators were calculated: Relative seed germination (RSG), relative elongation ratio of Shoot (RERs) and root (RERr), Inhibition percentage of germination, shoot and root length (I), and root/shoot ratio. Means and standard deviation were calculated and means were statically analyzed with one – way ANOVA, LSD test was chosen to compare differences between treatment means at a probability levels (0.01, 0.05). The result showed that extracts had greater effects on seedling growth rather than on germination and all measurements were affected, extracts had inhibition effects on root length of the two tested species, shoot length of alfalfa, but a stimulation effect on shoot length of common purslane. All root / shoot ratios were significant in all treatments of common purslane, and alfalfa treated with Aleppo grass only, while the seed germination differences were generally non – significant, Aleppo grass extracts were more effective than that of sterile oat, and the effect generally increased by increasing concentration.
