نفذت التجربة على تربة رملية طمية، و ذلك تحت الظروف الحقلية المروية في محافظة ديرالزور خلال العامين ١٩٩٨ و ١٩٩٩ ، بهدف دراسة تأثير مواعيد الزراعة ومعدلات البذار في نمو صنفين من اللفت الزيتي، برومين و VEM و إنتاجيتهما لمعرفة مدى نجاح زراعة هذا المحصول في محافظة دير الزور.
A field experiment was conducted on sandy loam soil under the irrigation conditions in Deir- ezzor during the years of ١٩٩٨ and ١٩٩٩ to study effect of planting time and seed rate on growth and productivity of tow varieties of rape crop Brasica napous var. oleifera (Bromin & VEM).

This research was carried out during 2009/2010 growing season in
swiri region which locates about 30 Km at the west of Homs city ,
located in the first stability region where the annual precipitation is
about 400 mm .
One cultivars of faba (Vicia
faba) was sown on three seeds rate
(high seed rate 220 kg/h – medium seed rate 185 kg/h – low seed
rate 150 kg/h) and three sowing date (15/11 – 30/11 – 15-12 ) 2009.
The objective of the research is to identify the optimal date of
planting when mutual intercropping (line: line) is used in planting
beans Phaseolus vulgaris L. and sweet corn Zea mays rugose L.
This cultivation was carried out in the farm of the Faculty of Agriculture at Damascus University during the 2013-2014 agricultural season to study the effect of seeding rate per unit area and planting dates on yield and its components for three barley genotypes under rain-fed conditions.
The research work based on an economical study on sugarbeet crop in Deir
Ezzor during the period (١٩٨٠–١٩٩٦) and the prospective horizons of it
through the cultivated area, yield and total production in order to know the
extent of cultivation deve
lopment and the factors influencing this crop.
Results showed that the area under sugarbeet was unstable which negatively
reflected on the yield and production during the studied period.
However, these changes were not important statistically for the cultivated
area (non-significant regression), while the regression was significant for the
yield and production. The results also showed the presence of negative relation
between the area and productivity of this crop.
The aim of this study was comparing between three potato cultivars: "Afamia,
Loulou and Tadmur" which are planted in two different times (spring time and autumn
time), for the plant old age and some yield properties and some quality properties. Aft
er
ripping and harvesting, result showed superior Loulou to Afamia and Tadmur in most
parameters at the two planting times, so the productivity of Loulou was more than Afamia
by 6 ton/h in the spring and 1.6 ton/h in the autumn. For the starch and dry matter content,
Loulou tubers in the two planting times contained more amount than the other cultivars,
and more than the global average (%14 starch, %22 dry matter).
