The objective of this research to study the chemical composition and microbial load
for some types of pies by performing various chemical and microbial analysis of samples
collected, from different parts of the Syrian coast which are famous for its
production.
This study showed a large variation in the chemical composition of samples by type
of the pastry and place brought from, for example, the proportion of dry matter for peppers
and chard pies collected from Banias was, 75.71% and 44.90%, respectively, and the
percentage of dry matter was 73.88% and 76.18% and the proportion of protein was,
17.76% and 24 .88% for cheese pies collected from Tartous and Latakia 1, respectively.
This study indicated that all the pies contain a high percentage of fat [the lowest in chard
pies (17.64%) and the highest in cheese pies (38.12%)]. Furthermore a high percentage of
sodium was found (the highest in cheese pies 15.31 mg / 100 g and lowest in pepper pies
7.82 mg / 100 g).
The study also showed that these meals meet international standards in terms of
content of lead, cadmium, Nevertheless they are poor in fiber content except for chard pies
which were the most balanced in terms of components, making it the best type of pies in
nutritional aspect.
Finally, the results showed that the microbial load was too high, as the total census of
bacteria was higher than 105 and the total census of yeasts and fungi was higher than 102.
In addition, all pies are not conformed to the Syrian legislation. The study also showed
absence of E.coli and St. aureus of all samples.
In this study, trends of annual and seasonal precipitation time series for the period of (1971–2006) were analysed for three meteorological stations (Lattakia, Tartous and Safita) located in the coastal region of Syria, by linear regression and Spear
man's rho tests.
The results showed a decreasing trend of annual precipitation in Lattakia and Tartous stations and increasing trend in Safita station. At the seasonal time scale, a decreasing trends of winter precipitation in Lattakia station and of spring precipitation in all stations were observed. While an increasing trends of winter precipitation in Tartous and Safita stations and of autumn precipitation in all stations were observed. Although, all of these negative and positive linear trends, both at the annual and seasonal time scales are not statistically significant at 5% level, but they can have severe effects on water resources, rivers regimes and success of rain-fed crops in the study areas
Ornamental plants considered one of the modern plantation, which should be
introduced in the future agricultural development plan confirmed by field studies for the
most important ornamental seed plants as a samples for data collections.
Through i
nformation and field data it can be concluded that, most of nursery's of
ornamental plants were in a small size (less than 2.5 hectare) in comparison with some
other propagated plants due to the absence of specialization. We observed a shortage in a
propagated plant materials especially cut-flowers which considered the most important
product.
This research observed also many problems facing the producers leading to high
production cost: preliminary materials, agriculture and propagation materials, expert
workers beside obstacles in exporting and absence in observation and governmental help.
The aim of this study was to determine some physical, chemical properties and
microbiological density (fungi –bacteria) of a Pine forest soil in the coastal region
(Mehwarti forest, Banias), where Pinus brutia is the main dominant plant.
Three soi
l profiles were carried out and their morphological characteristics were
determined, the thickness of accumulated organic residues and GPS data were also
recorded.
For physical and chemical analysis, samples from each profile horizon were taken
and air- dried, whereas for the microbial diversity analysis, samples were taken twice in
autumn and spring, and transported and stored at 4C.
The results showed that the studied soil belongs to Alfisol Order with A -Bt – C
profile types. Our results also showed that the soil depth was (85-100cm) and the texture
was clay with a high porosity in all studied soil horizons.
The content of calcium carbonate in the studied horizons was closely similar and
increased with soil depth, whereas the pH ranged between 6.8 and 7.9. The results
indicated that the organic matter decreased significantly with soil depth that affected the
microorganisms density which behave in the same manner. This decreas was very clear in
the first horizon especially in spring.
The medicinal and aromatic plants (thyme Khalili) is one of important economic
crops were introduced to the Syrian Agriculture recently "as one of the most important
alternative crops, especially" in the coastal region, The goal of research is to c
larify the
economic importance of agriculture thyme Khalili in the coastal region, This study was
conducted on all farmers who were counted on the ground in Tartous and Latakia
Governorates, there were 213 farmers ,with planted area reached to 565 acres in 2015.The
indicatives of economical feasibility based on data and statements gathered from site of
research and relying,were used in the economical evaluation .The study showed that the
totally achieved profit per annum from one acre of (thyme khalili) amounted to
151451.81 Syrian Pounds , and profitability coefficient in proportion to the productivity
cost has amounted to 283.64%, also the time indicator of capital recovery for (Thyme
Khalili) has amounted to 2.82 years.
