The research was carried out during 2009 – 2010 in Al – Hasaka – Amoda – to study the effect of cattle manure at the rate of 30 ton/h1, and four organic green fertilizers (Lentil, Vetch, Faba bean and Barely) on plant area and earliness properties of cotton crop compared with chemical fertilizer 400 kg/h1 urea, 83 kg/h1 P2O5 and 25 kg/h1 K2O.The study showed that the cattle manure significantly increased (plant area, lower first fruiting branch, earliness of flowering and boll maturity) when compared with all studied fertilizers, the increase reached (190. 92 Cm2, 0.30 pod, 1.50 day and 0.90 day) respectively. When compared with chemical fertilizer, the legume green fertilizers (Lentil, Vetch and Faba bean) significantly increased the plant area when compared with the control. The legume green fertilizer (Lentil) significantly increased the earliness of flowering (2.73) day and boll maturity (2.21) day when compared with the green fertilizer (Barely). The chemical fertilizer did not significantly affect the earliness of flowering and boll maturity when compared with the legume green fertilizer (Lentil) during the two seasons.

Research summary
تم تنفيذ هذا البحث خلال الموسميين الزراعيين 2009-2010 في محافظة الحسكة، منطقة عامودا، لدراسة تأثير أنواع مختلفة من الأسمدة على مساحة المسطح الورقي وصفات التبكير لنبات القطن. تضمنت الدراسة استخدام السماد العضوي الغنمي بمعدل 30 طن/هـ وأربعة أنواع من السماد العضوي الأخضر (عدس، بيقية، فول، شعير) مقارنة مع السماد الكيميائي. أظهرت النتائج تفوق السماد العضوي الغنمي في زيادة مساحة المسطح الورقي وانخفاض توضع الفرع الثمري الأول، والتبكير في الأزهار ونضج الجوزات مقارنة مع كافة الأنواع السمادية الأخرى. كما تفوقت الأسمدة الخضراء البقولية (عدس، بيقية، فول) في زيادة مساحة المسطح الورقي مقارنة مع الشاهد. ولم يؤثر السماد الكيميائي بشكل معنوي في التبكير في الأزهار ونضج الجوزات مقارنة مع السماد الأخضر (عدس).
Critical review
دراسة نقدية: تقدم الدراسة معلومات قيمة حول تأثير أنواع مختلفة من الأسمدة على نبات القطن، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين المزيد من التفاصيل حول الظروف البيئية والتربة التي قد تؤثر على النتائج. ثانياً، لم يتم مناقشة الجوانب الاقتصادية لاستخدام الأسمدة العضوية مقارنة بالكيميائية، وهو جانب مهم للمزارعين. وأخيراً، كان من الممكن توسيع نطاق الدراسة ليشمل مواسم زراعية إضافية لضمان استقرار النتائج.

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
A survey was conducted to determine the frequency and mean densities of plant-parasitic nematodes associated with cotton crop (Gossypium hirsutum L.) after the harvesting season 2008 in Syria. Results showed that twelve genera of plant-parasitic n ematodes were found associated with cotton crop roots. The distribution of nematode genera varied between the Syrian governorates, Pratylenchus spp., Meloidogyne spp. and Rotylenchulus infect most cotton fields in all syrian governorates. The distribution was relatively uniform between the governorates. They occurred in 80.7%, 46.6% and 32.95%, respectively, of tested fields with an average density of 137.2, 59.6 and 574.3 juveniles/100 cm3 soil, respectively. meanwhile, the genus Tylenchorhynchus was found in central region only. Rotylenchulus was more prevalent in the heavier soils, but Meloidogyne. was not influenced by soil type. The other nematode genera detected in this survey were less frequent, their frequency of occurrence were for Hoplolaimus (19.3%), Scutellonema (31.8%), Tylenchorhynchus (31.8%), Helicotylenchus (30.7%), Rotylenchus (36.4%), Tylenchus (18.2%), Xiphinema (3.4%).
The reasearch was carried out during 2009 – 2010 in Al – Hasaka – Amoda - to study the effect of cattle manure at the rat of 30 ton / ha , and four organic green manure ( Lentil, Vetch, Faba bean and Barely) on soil content of organic matter and so me mineral elements compared with chemical fertilizer 400 kg / ha urea , 83 kg / ha P2O5 and 25 kg / ha K2O . The manure significantly increased organic matter , phosphorus and potassium concentrations compared with other fertilizers ( chemical and green fertilizers ) . All green fertilizers ( Lentil , Vetch , Faba bean and Barely ) significantly increased organic matter , nitrogen and potassium concentration compared with the control without using any fertilizer , the tillage depth ( 0 – 10 ) cm significantly increased soil content of organic matter and nitrogen compared with deeper tillage ( 25 – 30 ) cm during the two seasons .
The research was conducted during the agricultural seasons 2016,2017 m in the Syrian coast in Tartous governorate, the village of Beit Sheikh Yunus. To study the effect of organic and chemical fertilization on some productive traits (number of flow er/plant, fruit weight /plant, weight of 1000 fruit gr, fruit yield Kg/h, harvest index%) of Coriander plant.
The experiment was carried out during spring season 2016 to study the effect of foliar spraying treatment with Tecamin Flower 2.5 ml/L in comparison with distilled water, on growth of three hybrids of tomatoes at two different levels of irrigation (100 and 50 % of field capacity). Three sprays were conducted started from flowering with two weeks’ interval. The results showed that ‘Finenss’ hybrid had significant differences in plant height, branches per plant and leaves number per plant. ‘Hadeer’ hybrid had superiority in dry matter ratio and content of chlorophyll in leaves. Reducing the level of irrigation resulted in a significant decrease in plant height, total branches number, versus an increase in the leaves number per plant, total leaves area and the percentage of dry matter. The results showed that the treatment with Tecamin flower led to a significant increase in all indicators studied. The interaction treatments shoed that Hadeer hybrid irrigated in level 50 % and spraying of nutrient solution (Tecamin flower) had a significant increase in dry matter ratio and chlorophyll content in leaves. While the hybrid Finenss which irrigated in level 100 % with nutrient solution (Tecamin flower) had a significant increase in leaves number per plant and total leaves area.
