نفذ البحث خلال الموسم الزراعي 2016 في منطقة غرب حمص تلكلخ قرية سميكة و ذلك لدراسة تأثير الجفاف المائي على طرازين من الذرة الصفراء Zea mayes L. هما: الهجين الفردي باسل1 و الهجين الزوجي باسل2 خلال مراحل فينولوجية مختلفة من النمو (البادرة، النمو الخضري، الازهار، النضج الفيزيولوجي) بالإضافة الى الشاهد (بدون اجهاد مائي)، و بثلاثة مكررات لكل معاملة. و نُفذت التجربة وفق تصميم القطع المنشقة لمرة واحدة، و بثلاثة مكررات.
The research was carried out at a field in Talkalakh region- Al smeka village in Western Area-Homs Province . The research objectives to study the effect of water stress conditions on tow hybrids of Zea mayes L. ( Basel1 and Basel2) during different phonological stages(seedling, vegetative growth, flowering, physiological maturity) and control (no water stress) . Split-plot design with three replications was used.

A hydroponic culture experiment was conducted under the green house
conditions, at the general commission of scientific agricultural research, and
the faculty of agriculture, Damascus university, during the year 2002-003.
The objectives of this in
vestigation concentrated on the influence of four
salinity levels (0-50-100-150 mM NaCl) on some physiological parameters of
eight sorghum genotypes. The experiment was designed in a RCB design with
three replications.
Chickpea (Cicer arietinum L.) in the Mediterranean climate can experience
two types of drought: intermittent drought stress and terminal drought stress.
A study was conducted during early August 2002 to early April 2003 under
glasshouse conditions
, to study the response of six chickpea genotypes, four
Kabuli and two Desi, to soil moisture levels.
The type of tillage methods is considered to be as an important
factor for seed bed preparation, consequently, this will be reflected
in the quantity and quality of production, in comparison to control
(minimum tillage) different types of tillage
methods were used such
as turning plough, standard disk plough etc, for Anise Pimpinella
anisum seed bed preparation, the experiment was conducted in the
western area of Homs province.
This study was carried out during 2010-2011 growing seasons at the
Maize Researches Department (G.C.S.A.R.) Damascus. To estimate
heterosis for number of rows per ear, ear length, ear diameter, 100- kernel
weight, and grain yield.
The present investigation was undertaken to estimate phenotypic
correlation and path coefficient analysis for grain yield and its components in
maize. Four local genotypes of yellow maize were evaluated in 2008 and 2009
growing seasons at two loca
tions i.e. Damascus and Dir Al-Zor under three
nitrogen fertilization levels (130, 195 and 260 of N. ha-1), The nitrogen fertilizer
was applied at two splits. Split split plot design was used with 4 replications.
Results of phenotypic correlation values showed that grain yield at Damascus
location was positively and significantly associated with ear height (r= 0.204**),
ear length (r= 0.205**) and number of rows per ear (r= 0.228**). On the other
hand, grain yield at Dir Al-Zor location was positively and significantly
associated with all studied traits at combined data whereas, it was positively
and significantly associated with ear length at three levels and combined data
(0.305*, 0.410**, 0.347** and 0.375**, respectively). The data of path coefficient
analysis showed that ear length, ear height and number of rows per ear had
positive direct effects on grain yield variation and thus grain yield
improvement can be achieved through selection for ear length and ear height at
Damascus location (11.06%). On the other side, data showed that each of ear
height, number of kernels per row and 100-kernel weight had positive direct
effects on grain yield variation (32.98%) and thus, 100-kernel weight can be
considered as selection criteria may lead to the improvement of grain yield in
yellow maize at Dir Al-Zor location.
