The research study was conducted in Hama Governorate during the
agricultural season of 2010 - 2011 through a stratified random sample of 201
farmers who cultivate irrigated durum wheat in the research area in order to
measure the yield gap, the pr
oductive efficiency divergence among farmers and
to determine the effect of using different amounts of the productive factors in
the production process. It also aimed to determine the contribution level of
these factors in the gap formation, as well as to determine the production phase
in which farmers of the sample stand. Descriptive analysis methodology in
addition to the multiple regression technique were used to estimate production
functions. Results showed a yield gap up to 32.6% between farmers in the first
phase and those who are in the fourth phase. The reason why productivity in
large size farms was higher than in small size farms that the second production
stage, the profitable one occurred in large size farms, while the first production
phase occurred in small economic capacity farms. So, another combination of
the production inputs can be used in order to reach a marginal product value
which equals the price value and to increase the production level plus the
productivity of the farmers in the research area.
In spite of an increase of farming experiance, producers are still facing
many obstacles which affect negatively on their final income.
It is clear from this study the decrease of productivity per unit area of wheat
and cotton crops and high produ
ction cost, caused decrease of the final income.
Most of the farmers, were not satisfied with cultivation of these crops, due to
increase of production cost, unsuitable price, lack of cultivation requirements
and the prices rising…..etc.
Also, the extension services offered to the farmers are poor and not at the
required level. That was the most important reason for the decrease of the
productivity. Consequently, it is possible to develop the agricultural activity by
improving the extension services and decreasing the prices of production
requirement and improving the selling prices. Therefore, it is necessary to
decrease the production costs of wheat and cotton crops, increase their
productivity, improve and activate the extension units work and spread
awareness and knowledge about modern methods of cultivation as well as ways
of decreasing the productivity costs, the factors which help to increase the
productivity from unit area, and acquainting the farmers to other crops, which
could be alternative crops in the future.
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.
This research was conducted to determine the most responsive phenological
stage for supplementary irrigation of the durum wheat in a primary stationary
region.
It consisted of six different water treatments in addition to control (non
irrigated)
:
1-From planting to seedling emergence; 2-From planting to tillering; 3-From
planting to booting; 4-From planting to flowering; 5-From planting to the end of
the milk stage; 6–Sowing irrigation and irrigation according to necessity
throughout the milk stage.
The study has been repeated in four blocks for three seasons from 2002 to
2005. The results of the first two seasons showed that the:
The treatment from planting to booting, was canceled because of the rain and
soil dampness during this growth period. A significant increase in production,
water use efficiency, and one 1000 kernel weight, of both 5th and 6th treatments was
noticed in comparison with other treatments and the control. Results of the three
seasons were varied due to the environmental variation in temperature and amount
of rainfall.
