تم اختبار تأثير موعد الزراعة المبكرة أو المتأخرة لمحصول القمح بالمقارنة مع الموعد التقليدي لزراعته في منطقة صوران ( 20 كم شمال مدينة حماه ) و الموافق لمنتصف شهر كانون الأول، و ذلك في نسبة إصابته بدبابير الحنطة المنشارية. بينت النتائج أن التبكير بزراعة القمح عن الموعد التقليدي لزراعته، أدى إلى كسر التزامن بين فترة تطور القمح الأكثر ملائمة لإصابته بدبابير الحنطة المنشارية، و فترة تواجد هذه الحشرات في الحقل.
This research was conducted in a field of wheat located at Suran (20 kilometers to the north of Hama city). The aim was to study the influence of wheat planting date on wheat stem sawflies infestation levels. The research showed that the early wheat seeding led to breaking the synchronization between the sensitive wheat development period suitable for the wheat stem sawfly infection and the existence of the insects in the fields.

In the present study, the susceptibility of four varities of wheat Maxipak 65,
M221×M24, Saberbek and Condoras in addition to the hybrid F4 (from the
hybridization of Maxipak-65 with M221×M24 for four successive generation)
against khapra beetle d
uring storage was estimated. The population growth of
the pest and percentage loss due to pest infestation were taken as criteria for
measuring resistance the against insect. The study indicate that the hybrid F4
was the best in productivity and early in production which are favorable
characters but contrarily it was highest susceptibility toward the insect
infestation. When the insect reared on the hybrid F4, appeared the highest
population density and at the same time the infestation caused in the highest
loss weight percentage. On the other hand the Maxipak-65 variety showed the
lowest population density of the pest and the lowest loss weight percentage due
to infestation than the other varieties and hybrid F4. This result indicates that
resistant character depressed during inbreeding during F4 hybrid production
in compared to parents therefore it must be early consumed to prevent the
infestation by the insect studied.
The research was Carried out in Jisr area in the province of Idlib during the growing
season 2013 - 2014 to study the effect of planting dates in autumn sowing 28/9/2013 = (1),
8/10/2013 = (2), 18/10/2013 = (3) and spring sowing 18/3/2014 = (1), 28
/3/2014 = (2),
8/4/2014 = (3) on yield and growth parameters.
The results showed that the autumn sowing has a significant increase in growth
parameters compared to spring sowing: adapting coefficient (76.67-82.28%), Plant hight
(67.15 - 56.3 cm), number of branches/plant (11.63 - 6.84), number of head/Plant (21.39 -
17.76), oil content (23.19 - 20.68)%, yield petals (96.12 - 60.57) kg/ha, seed yield (1331.82
- 768.31) kg/ha, oil yields (315.15 - 158.99) kg/ha to autumn and spring, respectively.
While maturity date of autumn plants was delayed compared to spring (245.33 - 145.33)
Day.
When sowing was of autumn, growth parameters of third soing date were a
significantly higher compared to both the second and first sowing: number of branches /
plant, number of heads / plant, number of seeds / head, oil ratio (%), oil yield (kg/ha),
yields seeds ( kg/ha), petals yield (kg/ha). Wheras the first sowing date has delayed
maturity date compared of both the second and third sowing dates.
When sowing was in spring, growth parameters of the first sowing dates were a
significantly higher compared to both the second and third except for days to maturity.
We evaluated some of the qualities of productivity for lentil

Agriculture led on the first date (December 15) and in the

This research discusses an economic study of wheat crop in Syria during the
period of forty years (from the sixty to the end of the twentieth century)
regarding the production, domestic supply from wheat for consumption with
calculation an equatio
n to the general regression for development of each of
them. To clarify the food gap positions for wheat and coefficient of selfsufficiency,
consumption per capita from wheat and percentage of its
consumption from durum wheat, the factors affecting consumption with types
of nutritive use of wheat and its forms.
The research was classified to a group of secondary titles. The study starts
with an introduction to identify the World and the Arab status for wheat
consumption. After determining the research objectives, material was
presented and ended up with a conclusion and an abstract.
This experiment was conducted at the Faculty of Agriculture, Damascus
University (2001 – 2002), to assess the effect of radiostimulation of seeds of two
durum wheat varieties (Hourani and Cham 3) on some morphological traits
and yield components,
by using three doses of gamma rays (10, 15, and 20 GY).
The study showed significant differences among radiation doses. The high
doses (15, 20 GY) caused a significant deterioration in growth and development
of plants, as well as yield components of the two varieties.
