هدف البحث إلى قياس الكفاءة الاقتصادية والفنية باستخدام تحليل دالة الإنتاج الحـدودي العـشوائي لمزارِع القطن المروي بطريقة الري السطحي في منطقة القامشلي بمحافظة الحـسكة. جمِعـت البيانـات الأولية استناداً إلى المسح الميداني، و تم تطبيق أسلوب العينة الطبقية العشوائية في اختيار عينة البحث، سحبت 89 مزرعة موزعة على 12 قرية تطبق نظام الري التقليدي. بينت نتائج التحليل أن قيمة الهامش الإجمالي لوحدة المساحة بلغت نحو 4.10308 ل.س/دونم، و قيمة الهامش الإجمالي لوحدة النقـد 625.0 ل.س. بعد تطبيق دالة الإنتاج الحدودي العشوائي تبين أن التكاليف المتغيرة مسؤولة عـن 38 % مـن التغير في المردود بمعنوية مرتفعة، و لا زالت المزارِع في مرحلة الغلة المتزايدة، و فيمـا يتعلـق بمـورد الأرض و المياه، فقد تبين أن مزارِع القطن وصلت فيها إلى مرحلة الغلة المتناقصة. أما غلة الحجم فكانت سالبة، مما يعني عدم جدوى التوسع في إنتاج القطن المروي بالنظام السطحي التقليدي، كما شكل متوسط قيمة الكفاءة الفنية في هذه المزارِع تبعاً للنموذج نسبة 58.88 ،% و حقق العدد الأكبر من المزارِع كفاءة فنية أعلى من المتوسط في العينة المدروسة.
The research aimed to measure the economic and technical efficiency using analysis of the random border production function (Stochastic Frontier Analysis) for cotton farms irrigated by surface immersion way in Qamishli district in Al Hassakah province. Preliminary data for 89 farms spread over 12 villages were collected on the basis of field survey using the stratified random sample in selection the research sample. Results showed that the value of the gross margin per unit area amounted to about 10308.4 SP /dunums and the value of the gross margin per unit was 0.63 SP. It was found that the variable costs were responsible significantly for 38% of the change in the return and farms are still in the phase of yields increased. This indicated that cotton farms had reached the stage of diminishing returns and the yield size was negative. Thus, it is not anymore recommended to increase the cotton production irrigated by surface way. It was also found that the average value of the technical efficiency of farms amounted 88.58% and the largest number of farms had achieved a technical efficiency higher than the average in the studied sample.

The study aimed at evaluating and studying the economic efficiency of farms fattening
sheep in Homs during the period (2008-2013), where the study was conducted on a sample of
25 farms, the average number of sheep, where about 25 head of Awas, by c
alculating the costs
and revenues, and using some of the economic indicators, where The results showed the
following:The average revenue before the crisis to about 3743138 sp , and during the crisis to
about 690525 sp.The average cost of producing 1 kg of gross weight of the animal for 195 sp
before the crisis , and about 334 sp during the crisis .The average annual net profit before the
crisis to about 427017 sp, and during the crisis to about 543224 sp.The average net profit
margin before the crisis has reached about 38%, and during the crisis, about 24.6%, and
reached average income per unit spending (rate of return simplex) before the crisis about 1.6
/unit spending, and about 1.4 /unit spending during the crisis. The average Profitability
Coefficient for the capital invested by the crisis reached about 106.3%, and about 69.7 %
during the crisis, but for the average coefficient profitability for the pre-crisis production costs
have reached about 61.8%, and 39.5% during the crisis, the average time of the restoration of
the invested capital before the crisis reached about 1.7 years, about 2.8 years during the crisis.
The study also demonstrated an outbreak many of the mistakes common among farmers like to
use the same combination of feed during the grow-out period and the lack of commitment by
giving vaccines and not making Aldrees and silage and fodder buy most of the black market,
which makes farmers vulnerable to the monopoly of the merchants. Which requires urgent
intervention and more effective in order to expand the production of red meat, and to be
covered by the development plans of the state, and work to protect the sheep of the country and
prevent smuggling and to provide support and encouragement necessary for farmers to practice
their profession fattening, especially after the reluctance of some of them for this the
profession during the crisis, and working to educate farmers on the need to use methods of
fattening more economically feasible, and conducting all necessary for the development of this
important productive sector.
The aim of this research is to estimate the structure of production
costs and consequently to derive the economies of scale for the
irrigated tomatoes crop in Al Hasskae region. The search is adopted
on the questionnaire method for sample included
(15) village by
using random sample of villages in AL-Hassake region, and the
number of sampled population (100) farmer to the season
2012/2013, 2013/2014.
The main objective was to study the economic efficiency of Durum wheat in
AL-Hassaka governorate during the growing season of 2010/2011 through a
stratified random sample included 119 farmers distributed in 10% of the target
villages. The results
showed that Duma 1 variety had achieved the highest
proportion in relation to the rate of adoptions and the highest adoption rate
compared with other varieties cultivated with irrigated Durum wheat in ALHassaka
governorate. Sham 3 variety had also the highest adoption rate
(47.47%) and widely distributed compared with other varieties Durum wheat
cultivated as a rain fed crop. The results also showed that the net return of
irrigated Durum wheat was in AL-malkia and amounted to 1653.17 Syrian
Liras/ Dunum while losing -261.50 Syrian Liras per Donum in AL-kamshli.
Duma 1 variety reached the highest net return (2443.58 Syrian Liras per
Donum) of irrigated Durum wheat. The net return of rain fed Durum wheat
was observed in AL-Malkia and amounted to 792.92 Syrian Liras per Donum
while losing -158.18 Syrian Liras per Donum in AL-kamshli. Sham 7 variety
had the highest net return of rain fed Durum wheat and amounted to 1847.48
Syrian Liras per Donum.
The research was conducted at Al- Hassaka province during the 2010 - 2011
season to study socio-economic factors and other factors affecting the decision
of wheat farmers to adopt the technology of modern irrigation and to identify
the barriers th
at limit the adoption of these techniques. Correlation and binary
logistic regression was applied for data analysis.
The results showed that 77.78% of the total farmers studied were using
modern irrigation to irrigate their wheat crops and the rest were using
traditional irrigation and this percentage is expected to increase from 77.78%
in 2010 to 95% in 2025 with an annual rate of nearly 1.15%. Sprinkler
irrigation adopted by larger percentage (63.33%) of farmers who adopted
modern irrigation techniques and followed by the developed surface irrigation
on lines (11.11%). It was observed that the high cost of the network played a
fundamental role in the lack of 42.55% of farmers to adopt modern irrigations
Statistical analysis showed that there was an inverse significant relationship
between each of independent variables (percentage of farming labor force to
total family labor force, farmer's experience) and the dependant variable
adoption of modern irrigation techniques but there was a positive significant
relationship between adoption of modern irrigation and other independent
variables such as, cereals yield, farmers education level and direction of the
farmer towards the agricultural extension.
The aim of this research was to measure the technical efficiency of cotton farms
with surface irrigation system using Data Envelopment Analysis (DEA) in the field
school in Idleb governorate. Preliminary data was collected based on field surveys,
and random sampling. 34 farms in the villages of Meless and Segar were chosen
for the season 2014.
