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 research was conducted in Dabba site for Agricultural Scientific Research at Lattakia region in the growing season 2011 during the period from early June to mid-October. The experiment included four cultivars of peanut (ICGV 92022, C16 local 262,
Souri, Al-Baladi), three row spacing (40, 60, 80 cm), and two levels of number of plants per hole-1 (one plant per hole-1, two plants per hole-1). The experiment was designed by using split-split plot design with three replications.
The results of the study showed that Al-Baladi variety was superior to all other cultivars in weight pods/plant (108.8 g), weight seeds/plant (56.8 g), weight 1000 seed (914.7 g) with yield of seeds reaching (3529 kg/h). On the other hand, ICGV 92022 was superior in number of mature pods (29.22 mature pod), in number of seeds/plant (53.90 seed) and in yield (3058 kg/h). Regarding the effect of row spacing, the spacing 80 cm between rows had given the highest values significantly for yield attributes in comparison with row spacing 40 and 60 cm. Yet the highest yield per unit area obtained with row spacing was 40 cm. As about the effect of number of plants per hole-1, two plants hole-1caused significant decrease in yield attributes and significant increase in seed yield in comparison with one plant hole-1
This study aimed at evaluating the productivity of common carp (Cyprinus carpio L.)
farmed in the floating-cages in the 16 Tishreen Dam between 1995 and 2004. The results
showed that the feed amount was about (5000 tons) in 1998, while it was about
(370 tons)
in 1995. The proportion of protein reached 33.71% in 2000 and 28% in 1996. The number
of carp fingerlings was 283000 in 4440 and 200550 in 1999. The fingerlings intensity in
the cage was 115.387 fingerlings / m³ in 1995 and 90.355 fingerlings / m³ in 2003. The
results also showed that the studied farm was not profitable in 1995 and 1998 because of
fish over-wintering, while it was in the remaining years. These results indicate that the
studied farm has successfully overcomed many of the problems and it was gainful in many
years. However, the main aim of the studied farm is providing the local market by
freshwater fish and offering many job opportunities.
Eight varieties of soft wheat T.aestivum L. were used in the study, four of which
were local (sham 6, sham 8, sham 10 and bohoth 4) and four introduced varieties obtained
from the Scientific Agricultural Research Center (Tugela, Betta, Bezenchukska
ya98 and
saratovskaya210) and grown during the periods (2011-2012 and 2012-2013) at Qabu Al
Awwamiyya near Lattakia City. The following readings were taken for the studied
varieties (yield, plant height, spike length, number of spikelets per spike, weight of 1000
grains, protein content proportion of gluten, ash, and moisture content). Data was analyzed
statistically using an analysis of variance. The results showed significant differences
between the local and introduced varieties on the one hand, and between the varieties
themselves on the other hand. Local varieties were better than the introduced varieties with
regards to the protein content, moisture content, proportion of gluten, yield, spike length,
number of spikelets per spike, and the 1000-grain weight. The introduced varieties
however were superior in plant height and ash. The best varieties among local varieties
were (Sham 6 and Sham 10), and Betta among the introduced ones.
The search was conducted in Dabba site for Agricultural Scientific Research at
Lattakia region in the growing season 2011 to study some physiological and productive
parameters for peanut cultivars under the row spacing effect and number of plants p
er hill,
the experiment was designed by using split-split plot design with three replications.
The treatments of experiment included four cultivars of peanut (ICGV 92022, C16
local 262, Souri, Al-Baladi) and three row spacing (40, 60, 80 cm) and two levels of
number of plants hill-1 (one plant hill-1, two plant hill-1).
Six Syrian landraces of Rosa damascena planted at the faculty of agriculture
of Damascus University have been evaluated in this study. A big variation of
yield was noticed among the landraces. The landrace called (Mesraba) was
superior to others c
oncerning yield which was (112.2 g/plant). On the other
hand, (Erna) had got the highest content of oil (0.071%). Analysis of oil
implemented in Suleyman Demirel University in Turkey (Isparta) identified the
main components of oil such as: Geraniol (28-31%), Citronellol (26-30%),
Nerol (12-14%), Germacrene-D (6-8%), Nonadecane (4-6%) and Linalool (1-
3%). Besides, many trace compounds were detected such as: Eicosane, Eugenol,
Citral, Hexadecane and Rose oxide. The essential oil of (Almarah) had got the
highest quality.
This study aimed at checking the stability of some mutant lines from
soybean varieties in different locations and to select the best performing lines in
each location.
These lines 15 were selected according to previous experiments as being
early
maturing and/or that yield higher than the control. The study lasted three
years, the experiment plants were grown in 3 locations: Raqa, Idleb and
Lattakia. The experiment was designed as RCBD with 3 replicates for each
variety.
Results showed significant difference between lines, Locations and year in
both earliness and yield, A significant interaction was realized between (line X
location) and (line X year) for earliness and yield. For earliness (line X year)
was not significant. The reverse situation was realized for yield. Location. X
year of yield and earliness was significant. Earliness was correlated positively
with all characters (except for 100-seed-weight).
Yield was positively and significantly correlated with characters of all lines.
Three lines with higher yield than the control (142.61%) and same maturity
time were selected.
In spite of an increase of farming experiance, producers are still facing
many obstacles which affect negatively on their final income.
It is clear from this study the decrease of productivity per unit area of wheat
and cotton crops and high produ
ction cost, caused decrease of the final income.
Most of the farmers, were not satisfied with cultivation of these crops, due to
increase of production cost, unsuitable price, lack of cultivation requirements
and the prices rising…..etc.
Also, the extension services offered to the farmers are poor and not at the
required level. That was the most important reason for the decrease of the
productivity. Consequently, it is possible to develop the agricultural activity by
improving the extension services and decreasing the prices of production
requirement and improving the selling prices. Therefore, it is necessary to
decrease the production costs of wheat and cotton crops, increase their
productivity, improve and activate the extension units work and spread
awareness and knowledge about modern methods of cultivation as well as ways
of decreasing the productivity costs, the factors which help to increase the
productivity from unit area, and acquainting the farmers to other crops, which
could be alternative crops in the future.
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 research was carried out during 2014 and 2015 agricutural
season ,To study the effect of spraying cytokinin regulator on
