The experiment was carried out during2013-2014 Miaar Shaker village (Tartous) to determine the best method of irrigation on growth and productivity of Tomato plant in plastic green-house. Three method of irrigation were used in the experiment :(furro
w surface , surface drip and subsurface drip irrigation). Growth of plants, productivity and fruit quality were studies.
The results showed that surface and subsurface drip irrigation give more plant growth (leaves number and leaves area) more flowering and fruit production as compared with furrow irrigation method .The leaves number and leaves area in plant with surface drip irrigation was 31.49 leaves and 17078/plant while these number reached only to 22.91 leaves and 7057.86/plant in the furrow irrigation with significant difference . The productivity of plants was also higher in surface drip irrigation method(4.75 kg/ plant) without significant difference as compared with subsurface irrigation method and with significant difference as compared with furrow irrigation method (3.95 kg/ plant). The quality of fruits was better in surface drip irrigation (8.28% dry material ,5.02% TSS and 28.23mg vitamin c /100g) in fresh matter while these number were 7.18%, 4.98% and 20.96 mg/100g in furrow .
The irrigation method haven't affect in the: plant length ,and acidity percentage.
The aim of this research is to determine the role of mineral (NPK) and organic fertilization (Chicken manure, Cow manure and Chicken with Cow manure) on vegetative growth and flowering of Zinnia (Zinnia elegans). This research also examines the possi
bility of relying on this organic manure to present nutrients for the plant in order to reduce mineral fertilization.
The results show that the use of NPK (30, 20, 20 g/m2) or Chicken manure (2Kg/m2) has a positive impact on vegetative growth (plant height and average number of branches andleaves on the plant). They also show a positive effect on the flower developmentand flowering (early flowering, number of flowers and flower volume). These positive effects are reflected on the proportion of dry matter both in the vegetative and flowering part. The results indicate that plants fertilized with NPK or Chicken manure realize higher economic profit than the control and those fertilized with Cow manure.
The study was conducted in 2011 on 6-years-old citrus trees "Washington navel
141". It contained four treatments with three replicates for each treatment. The results
showed that:
The wastewater treatments showed superiority on the control in the
number of
vegetative growth and its length.
The number of inflorescence buds, was increased in the second treatment (irrigation
with 50% treated wastewater +50% normal water) (5. 37) which dominated the other
treatments.
The weight of fruit was affected by treated wastewater irrigation. Second treatment
(irrigation with 50%treated wastewater+50 % normal water) was better than the control
treatment. It was increased by (308. 3 g) compared to (259. 5 g) for the control treatment.
Fruit yield production per tree, was increased by second treatment (irrigation with
50% treated wastewater+50 % normal water) (28. 9kg) compared to (15. 3kg) for the
control.
Treated wastewater irrigation had positive effects in the quality of fruit
(Total sugar %), (T. S. S %) and the coefficient of maturity were increased in second and
third treatment compared to other treatments, while (T. A %) was decreased in all
wastewater treatments.
The research aimed to study the effect of size of container on the growth of
seedlings pepper "Snapper". Two different sizes of plastic containers, with
dimensions 8×8 cm and12×12 cm were used, Results showed that the use of
containers with large
dimensions had increased the growth of seedlings
compared with the use of smaller ones. A significant increase, of about 14%
was observed in the average length of seedlings and about 16% in the average
number of leaves produced in the large containers as compared with seedlings
produced in smaller ones. Also the fresh wet weight, whether for the plant or its
separate parts was significantly higher in seedlings produced in the large
containers. The plant fresh wet weight in the large container was 26.98 g vs.,
2.27 g in the smaller ones.
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.
يركز البحث على تقييم استراتيجية استهداف معدل نمو عرض النقد في سورية و مدى
تأثيرها و علاقتها بمعدل نمو الناتج القومي الإجمالي في الفترة ما بين أعوام 2000-2010م , و في سبيل ذلك يستعرض البحث مفهوم عرض النقد في الأدبيات الاقتصادية, و وسائل استهداف معدل
نموه عبر أدوات و سياسات البنك المركزي, و مرتكزات استراتيجية استهداف عرض النقد, وصولاً إلى استعراض التجربة السورية لاستهداف معدل نمو عرض النقد ضمن الخطتين الخمسيتين خلال الفترة 2000-2010 م, و ذلك باستخدام

This study aimed to evaluate the F1 non ripening tomato hybrids for yield
components and some other biological and morphological traits in the green
house.
This investigation included the comparesion of six tomato hybrids during
tow years (1999,
2000). Under the green-house conditions.
It has been found significant differences among the investigated hybrids
regarding to yield, plant hight, leaves number, flowers number, and the periods
from germination to flowering, germination to ripening, and flowering to
ripening, but, there was no any significant variation in fruits number and fruit
setting rate.
The aim of this research was to determined the role of humic acid (HA) and organic
fertilization (poultrey with cattle manure) on vegetative growth, flowering and cormels
production of Gladiolus (Gladiolus hybrida). Also investigating the ablity of
this organic
manure to provide nutrients for the plant in order to reduce the mineral fertilization.
Humax (50% humic acid) was used, and three applications of HA applied at 2 leaf, 2 and 4
leaf, and 2, 4 and 6 leaf stages of plant development.
The results showed that the use of humic acid had a positive impact on vegetative
growth (plant height and average number of leaves on the plant) it also showed a positive
effect on the formation of Spikes and flowering (early flowering, spike length, number of
flowers on spike).The positive effects were reflected on the proportion of dry matter in the
vegetative part.
The results indicated that plants sprayed with humic acid in presence of Chicken
manure produced higher cormels yield and economic profit than the control and those
fertilized with Cow manure. . Data also, Showed that T4 treatment (plants sprayed 3 times)
realized higher economic profit than authors treatment (112,66%).
The research was carried out during 2014 and 2015 agricutural
season ,To study the effect of spraying cytokinin regulator on
vigitative and fruiting charachterstics cotton plant.
