نفذ البحث خلال الموسميين الزراعيين 2009 – 2010 في محافظة الحسكة منطقة عامودا لدراسة تأثير السماد العضوي الغنمي بمعدل 30 طن/هـ و أربعة أنواع من السماد العضوي الأخضر (عدس، بيقية، فول، شعير) في مساحة المسطح الورقي و صفات التبكير لنبات القطن مقارنة مع السماد الكيميائي (400 كغ يوريا، 83 كغ P2O5، 25 كغ K2O/هـ). بينت الدراسة: تفوق التسميد بمخلفات الأغنام معنويا في زيادة (مساحة المسطح الورقي، و انخفاض توضع الفرع الثمري الأول، و التبكير في الأزهار، و التبكير في نضج الجوزات) عند مقارنته مع كافة الأنواع السمادية المدروسة و بزيادة وصلت إلى (190.92 سم2، و 0.30 سلامية، و 1.50 يوم، و 0.90 يوم) على التوالي عند مقارنته مع السماد الكيميائي، و تفوقت الأسمدة الخضراء البقولية (عدس، بيقية، فول) معنويا في زيادة مساحة المسطح الورقي مقارنة مع الشاهد، و أثر السماد الأخضر البقولي (عدس) معنويا في التبكير في الأزهار (2.73) يوم و نضج الجوزات (2.21) يوم عند مقارنته مع السماد الأخضر النجيلي (شعير) و لم يؤثر السماد الكيميائي معنويا في التبكير في الأزهار و نضج الجوزات مقارنة مع السماد الأخضر (عدس).
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.

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.
