أُجريت هذه الدراسة في حقول كلية الزراعة بجامعة دمشق في الموسـم الزراعـي 2002 ـ 2003 لاختبار كفاءة بعض المبيدات في مكافحة تربس البصل tabaci. T . تضمنت التجربة سبع معاملات و شاهدا بواقع ثلاثة مكررات، حيث زرع الثوم في 24 قطعة تجريبية مساحة كل منها 8 × 3 م. اسـتخدم مبيـد 5G Furadan%) 5 Carbofuran (مع التربة قبل الزراعة، و اسـتخدمت المبيـدات الـستة الأخـرى: ،(Brofenofos 320 g/L) Selecron 320 EC ،(Diafenthiuthiuron 250 g/L) Pegasus 250 SC (Imidacloprid 70%) ، الـصيفي الزيـت مـع Decis ،(Deltamethrin 50 g/L) Decis 50 EC WG 70 Confidor رشاً على المجموع الخضري و بواقع رشتين.
This study was conducted in Experimental Field of Agriculture Collage during 2002 – 2003 in order to test the efficacy of some insecticides in controlling onion thrips T. Tabaci. Seven pesticides and control were randomly distributed on 24 experimental blocks (8 ´ 3 m) cultivated with garlic. Furadan 5G (Carbofyran 5%) mixed with soil before cultivation. Other pesticides: Pegasus 250 SC (Diafenthiuron 250 g/L), Selecron 320 EC (Brofenofos 320 g/L), Deices 50 EC (Deltamethrin 50 g/L), Decis plus mineral summer oil, mineral summer oil and Confidor 70 WG (Imidocloprid 70%) had been sprayed twice.

This research was conducted at AlTieba Research Station, General Commission
for Scientific Agricultural Research (GCSAR) in 2012 and 2013 seasons, to study
the effect of different doses of gamma rays on growth and productivity of local
garlic Alli
um sativum L. cultivar “Yabroudi” in Syria. Cloves were exposed to four
different doses of gamma rays of 60Co source 1, 2.5 ,5 ,10 ) Gray). Randomized
Complete Block Design (RCBD) was used .The results showed the surviving plants
after 60 days of planting declined with the increase of dose levels. The percentage
of dead plants at the doses (2.5, 5 Gray) was 50 and 54 %, respectively. Also, it
was possible to obtain a larger number of viable mutations. Therefore, they could
be considered as close as to LD50. The dose (10 Gray) had a negative effect on the
length of the cloves’ germination period, leading to the death of all the plants after
60 days of planting, this could be considered lethal dose (LD100). The response of
the local garlic cultivar Yabroudi to the low-dose (1 Gray) of gamma ray was higher
comparing with other doses. This is due to the positive effect of this dose (Stimulus)
on the vegetative growth that was reflected on the productivity indicators. The
productivity reached (4.50 kg/m2), which was significantly superior to the control
(2.91 kg/ m2) and the two doses (2.5, 5 Gray), respectively (2.26, 1.60 kg/ m2).
The experimental was carried out to estimation the
influence of competitive irrigation, organic, and chemical
fertilization treatments as well as the interaction of them on
coriander plant (Coriandrum sativum L.) by FRCBD in three
replications.
The lack of information about the cultivation of coriander plant in Syria prompted us
to study the effect of four plant densities (33.33،10، 13.33 and 20 plant/m2)، and four levels
of phosphate fertilization (0107.2،160.8، and 214.4 of Superphospha
te 46%) on some
productive and quality traits of the coriander plant. This study was carried out in Tartous
province during the growing season 2014، using Randomized Complete Block design with
a Split Plot arrangement of treatments. The Results revealed that there were significant
differences between the treatments for the whole traits، in addition to a significant
interaction between density and phosphate fertilization. Although the densities (10، 13.33
and 20 plant/m2) varied in their effect، they had superiority upon the
control(33،33)plant/m2، and the density 10 plant/m2 had more important effect in terms of
increasing each of: branches number/plant، seed weight/plant، seeds number/inflorescence،
protein content in plants and seeds and beta carotene and chlorophyll. However، the level
160.8k.g/h of P2O5 increased the number of inflorescences/plant، number of fruits/plant
and seed weight/ inflorescence.
This study was conducted in order to evaluate the efficacy of the aqueous extracts
of three plants (Melia azedarach L., Smilax asepra L. and Styrax officinalis L.),
three pesticides (acetamiprid, abamectin and pyridaben) and releasing of two
preda
tors (Phytoseiuls persimilis Athias–Henriot and Stethorus gilvifrons Mulsant)
in controlling of Tetranychus urticae Koch populations in tomato greenhouse.
Genotypic and phenotypic coefficient of variance, broad and narrow-sense
heritability, expected genetic advance and relative genetic advance of earliness
characteristics in six pea hybrids produced by 4 x 4 half-diallel crossing scheme
were estima
ted. The results, in general, showed low values of phenotypic
coefficient of variance (in all crosses) of days to beginning of flowering and days
to marketable maturity; which may indicates to a low effect of environmental
variation on the expression of both these characters, but were medium to high
for number of low internodes and internode's length. Estimates of heritability
in broad sense were medium to high for days to beginning of flowering (0.42 –
0.90) and days to marketable maturity (0.42 – 0.91), and biased estimates of
narrow-sense heritability have been recorded in most of the crosses and in
majority of the parameters studied; so we can’t adopt them as reliable data.
The highest estimates of relative expected genetic advance of number for low
internodes have been observed in Mutant-3 x Dasargelo (25.95%) and
Dasargelo x Nassra (25.11 %) and for internode's length in Dasargelo x Oterlo
(37.31 %). The selection procedure can be effectively made for achievement
further improvement of internode's length in early segregating generations of
Dasargelo x Oterlo hybrid; because it has high values of genotypic coefficient of
variance, broad-sense heritability and relative expected genetic advance.
