هدف البحث إلى مقارنة أصناف البطاطا آفاميا, و لولو و تدمر المزروعة في موعدين مختلفين (عروةٌ ربيعيّةٌ و عروةٌ خريفيّةٌ), من حيث عمر النّباتات و بعض الصّفات الكمّيّة و النّوعيّة لدرنات المحصول النّاتج. و بعد تمام نضج المحصول و قلع الدّرنات أظهرت النّتائج تفوّق الصّنف لولو على الصّنفين آفاميا و تدمر في معظم المؤشّرات المدروسة و في كلتا عروتيّ الزّراعة, حيث زادت إنتاجيّة الصّنف لولو على أقرب منافسيه آفاميا بحوالي 6 طنّ/هـ في العروة الرّبيعيّة, و 1.6 طنّ/هـ في الخريفيّة. و بالنّسبة لمحتوى المحصول من النّشاء و المادّة الجافّة احتوت درنات الصّنف لولو في كلتا العروتين كمّيّةً تفوق الصّنفين الآخرين و تفوق النّسب العالميّة أيضاً (%14 نشاءٌ و %22 مادّةٌ جافّةٌ).
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. After 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).

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).
The effect of green manure and biofertilizer by using (Lupinus albus and
Lupinus albu s + Rhizobium) on some soil properties and potato growth and
production during two successive seasons of 2007/2008 and 2008/2009 was
studied. The results showed
that green manure provided the soil with 3.75
kg/m2 green organic matter including (398 g dry matter and 14 g nitrogen),
while lupinus albus + Rhizobium provided the soil with 4.55 kg/m2 green
organic matter including (581 g dry matter and 22.3 g nitrogen) and improved
soil chemical properties. The results showed as well that biofertilizer significant
improved potato growth parameters: plant and tuber dry matter, foliage
surface, foliage index, plant length, plant elements content (N,P,K,Ca and Mg),
tuber number and their content of nitrate and protein .The results showed as
well that biofertilizer significant improved marketing potato yield.

This research work was carried out in the nursery field of the Faculty of
AGgriculture in Tishreen Univesity during the spring growing season of 2012, it involved
studying some chemical characteristics of potato tubers of Five newly introduced vari
eties
of potato ( Atlas, Bureen, Bomba, Rumba and Orla), in comparision with Spunta variety as
a control.
It was showed that the hieghest large tuber were recorded in Atlas ,Burren and
Bomba. Bomba variety showed hieghest standards tubers (7.8 Kg/ m2). It was showed also
the hieghest dry matter (DM=20.5 %), and Ash content (1.01%) in tubers, were recorded in
Rumba variety. Bureen and Spunta varieties showed hieghest values of starch contents
(14.5 % and 14.4%) respectively. While Vitamin C (VC ( , was encountered ( 19.36, 17.6,
and 17.6 mg / 100g) for Rumba, Spunta and Bureen respectively. Also, the highest values
for protein content (1%) and the soluble solid (5%) in tubers were found in Rumba
variety.
The research was conducted on some olive
varieties known as Alsourani- Aldan- Mahazm Abu Satel- Alglet-
Alnepali, in the aim of comparing their tolerance against the stress
of salinity (sodium chloride) through some morphological and
physiological traits. Different concentrations of salt as well as to
the control (fresh water) were used in this experiment.
