نُفّذ البحث في مركز البحوث العلمية الزراعية بالقامشلي، التابع للهيئة العامة للبحوث العلمية الزراعية بسورية، في منطقة الاستقرار الأولى، خلال المواسم الزراعية 2011 و 2012 و 2013 بهدف معرفة تأثير إضافة مستويات مختلفة من الزيوليت الطبيعي (20-T2 طن/هكتار، 40 -T3طن/هكتار، بالإضافة إلى معاملة الشاهد بدون إضافة T1)، في إنتاجيّة القمح ضمن دورة زراعية ثنائية قمح/حمّص و في محتوى الطبقة السطحية للتربة من الآزوت، و الفوسفور، و البوتاسيوم المتاح. نفّذ البحث باتباع تصميم القطاعات العشوائية الكاملة، بثلاثة مكررات لكلّ معاملة.
The research was carried out at Al-Qamishli Agricultural Research Center, GSAR, Syira, during the seasons 2011, 2012 and 2013, in order to estimate the effect of adding different levels of a crude Zeolite (T2-20 tons/ha, T3- 40 tons/ha, in addition to the control (without adding Zeolite T1), on wheat productivity within a bilateral crop rotation was followed, consisted of wheat and chickpea, and on the content of nitrogen, phosphorus and potassium in the surface layer of the soil .The research was conducted using Complete Randomized Block Design with three replicates.

A field experiment was carried out to investigate the effects of organic
fertilizers (mushroom substrate residues, poultry manure and city compost)
and mineral fertilizers (NPK) on some properties and productivity of a
calcareous soil using chard
(Beta vulgaris) as a test crop. The plant was
cultivated at spring season 2009. The first cut was after 60 days of swing. The
results of experiment were: The NPK fertilizer significantly affected dry weight
of plant yield (157.6g/m2soil) and the efficiency of fertilizer in productivity was
50.8% compare to control (104.5g/m2soil). The treatment of 50% NPK + 50%
poultry manure gave the highest yeld compare to other treatments. However
the organic treatments did not differ significantly among them. Concentrations
of NPK nutrients in plant leaves were as follows: NPK > 50% NPK + 50%
poultry manure > poultry manure > 50% NPK + 50% mushroom substrate >
mushroom substrate > 50% NPK + 50% city compost > city compost. The
organic fertilizers decreased the NPK in plant and soil compare with NPK
fertilizer treatment. However there was no significant differences between NPK
treatment yield and 50% NPK + 50 % poultry manure treatment. It was
concluded that the use of 50% NPK +50 % orgnic fertilizer (specially poultry
manure) was important to get best result.
The research was conducted at Abo-Jarash farm, faculty of
agriculture, Damascus university during the two growing season
2011-2012 and 2012-2013 in order to evaluate genetic variability of
some lentils genotypes based on some physiological and
productivity traits associated with drought tolerance. The
experiment was laid out according to factorial randomized complete
block design with three replications.
The performance of some barley genotypes was evaluated under rain-fed
conditions in Dara'a (Izra'a) during two successive growing seasons (2009-2010/
2010-2011) in order to determine the most relevant physiological traits, which
are genetically as
sociated with drought tolerance and grain yield. The trial was
laid out according to the factorial complete randomized block design, with
three replicates. The leaf area index (LAI) was significantly lower in the wild
relatives compared with the varieties and land races. Relative water content
was significantly higher during the second growing season (87.19%) compared
with the first one (71.57%). Solute leakage was significantly lower during the
second growing season (69.50%) compared with the first growing season
(76.49%). It was noticed that the genotypes which have achieved significantly
higher grain yields, could also maintain significantly higher relative water
content in the leaves, (Acsad176, Acsad1182 and Acsad60), and were superior in
maintaining membrane integrity, and leaf area index, indicating the
importance of such traits in improving drought tolerance and maintaining
production capacity.
A field experiment was conducted during the two consecutive growing seasons
(2010/2011 and 2011/2012) at Ezra’ Research Station/Deraa/Syria in order to evaluate the
role of some agricultural practices in improving the performance of four wheat vari
eties
(Acsad1105, Acsad1229, Acsad885 and Acsad901) under rainfed conditions. The experiment
was laid according to factorial randomized complete block-split design with three
replications. The mean average of early vigor, flag leaf area, peduncle length and leaf area
index was significantly higher during the first growing season for the wheat variety
(Acsad901) at the first planting date with a nitrogen amount of (150 kgN. Hectar1), and
when nitrogen fertilizers were added twice (1.6-2.5, 53.4cm2, 16.3cm, 1.20 respectively).
The mean average of the same studied aspects, however, was significantly lower during the
second growing season in the case of the variety Acsad855 with regards to the early vigor,
as well as in the case of the variety Acsad1129 in the case of the leaf area Flag at a late
planting date, and without nitrogen fertilizers (3.6 4.5, 3.3 cm, 0.18, 16.6 cm2
respectively). The mean average of the grain yield was significantly higher during the first
growing season for two wheat varieties (Acsad901, Acsad1229) at the first planting date,
nitrogen rate 200 kgN. Ha-1, and when nitrogen fertilizers were added twice (660.4, 631.1
g.m-2 respectively), while it was significantly lower during the second growing season for
the variety Acsad1105, at a late planting date, and without nitrogen fertilizers (127 g.m-2).
Optimizing some important cultural practices helps increasing wheat grain yield by
improving morpho-physiological traits related to yield particularly the size of source
photo synthise (Leaf Area Index, Flag leaf area). The response of astivum wheat variety
was better compared to durum wheat. This shows the importance of improving crop
mangment factors in order to reach the maximum potential yield.
