The research was carried out in the agricultural season 2016-2017 the village of
DweirRaslan Tartous governorate with three planting dates (20 November - 10 December -
1 January) and three densities (12 - 14 - 16 plants / m2) Where the planting tim
e was the
main pieces and the plant density occupied the dissecting pieces once to study the effect of
planting date and plant density on some morphological characteristics of white thermos
plant.
The results showed that dates of the early dates (November 20) were higher in plant height,
with an average of 64 cm and surface area of the paper surface at an average of 24.367
thousand. M 2 / ha and in shape of the length of the century with an average of 7.50 cm.
As for the plant density, the plants of density12 plants / m 2 in the height of plant exceeded
an average of 65.6 cm and length of the century with an average of 8.13 cm, while the
plants of density 16 plants / m 2 in the area of paper area average 24.213 thousand. M2 / ha
The research was executed within the season 2016, in the west of
HOMS in the first settlement area.
The study has showed the effect of plant density and nitrogen
fertilization was studied on the growth and productivity of soybeans
Glycine max L . (Sb44).
This study was carried out in the farm of the Faculty of Agriculture
University of Damascus during the growing season 2014, to study the
productivity of the maize cultivar ("Gouta 82) and the hybrids (Basel
1 and Basel 2) under the influence of tw
o plant densities 17.53
thousand plant. ha-1 (70x20cm) and 53.11 thousand plant. ha-1
(70x40cm).
This search was conducted during 2014-2015 growing season in Agricultural
research station in Al Kraeim belonging to Al Salameah district in Hamah Provence in
order to study the effect of plant density on; First, the phenological stages of lentil p
lant
calculated in day unit. Second, the seed productivity in a lentil plant calculated in g/plant,
and then seed production in Hectares (Kg/ha-1).Lastly, percentage of seed protein content
in seeds. In this study, three plant densities were used (200, 250, 300 seeds/m2, and was
designed using Randomized Sectors in three replicates for each density. Results showed
that;
1) The low density plants (200 seeds/m2) was significantly better than other
densities (250 and 300 seeds/m2) in:
Reaching 50% seed germination (19.4, 20.5 and 22.5 day continually) and in
flowering stage (111.36, 113.6 and 114.7 day continually) and in maturation/Ripening
stage (134.4, 136.6 and 137.7 day continually).
Seed production per plant (1.553g/plant) in comparison by seed production of
other densities (1.487 and1.376 g/plant).
Percentage of seed protein (26.8%) in comparison by seed protein of other
densities (26.3 and 26.19 %).
2) The higher densities (300 seeds/m2) was better in seed production in aria unit
(1791.3 Kg/ha-1) in comparison by production of other densities (1492.7 and 1194.2 Kg/
ha-1).
This research was carried out through 2015-2016 growing season
belongs to the fourth stability at Gander village located on the
between Homs and Damascus .The aims of this research were to
study the effect of plant density on seed yield and its components
of faba bean (vica faba ) and to investigate the optimum plant
density of this crop in the region.

This research was carried out at a special farm at Balghounis - Banias during the
agricultural season 2013/14 to study the of effect plant density and variety and the
interaction between them on some productivity characteristics of faba bean plant.
Two
faba bean varieties were used : Balady (local variety) and Italian Super Simonia (new
variety in Syria). Five densities (20, 10, 6.67, 5, 4) plants/m2 were studied. A split plot
design with three replications was used, in which varieties were assigned to main plots and
densities to sub plots. The GenStat 12 program was used for statistical analyses.
The results indicated that Balady variety significantly surpasses the Italian one in
plant height during maturity stage. Also Balady variety showed a significant increase
compared to Italian variety in number of branches/plant, number of pods/plant and 100-
seed weight. On the other hand, Italian variety significantly surpasses the Balady one in
number of seeds/pod and seed yield, and it showed a significant increase compared to
Balady variety in seed weight per plant. Increasing of plant density led to an increase of
plant height and a decrease of number of branches/ plant, number of pods/plant and
number of seeds/pod. Decreasing of plant density led to decrease of 100-seed weight and
seed yield.
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.
The research was executed within the season 2015 ,in the west
of HOMS in the first settlement area.One kind (Alfarancy) of
chick pea Cicer arietinum L, was sowed in January on three
planted distances (4,8,15) cm, and three application rates of
Ur
ea fertilizer (N 46%) were applied (0,25,50) kg/ha each level
was applied with two equal patches.
Most results showed that the difference of the distances with
difference rate of Urea fertilizer has a big effect on the most
studied qualities.
Depending on the research results we founded that:The seeding
with 15 cm and applying 50 kg n/h surpassed most the other
treatment for seed weight for each plant, Results also indicated
that the seedling with (4cm with 25 kg/h) surpassed most the
other treatment for (high plant, high first pod). For
characteristics (biological yield, straw yield) that the seedling
with (8cm with 25 kg/h) surpassed most the other treatment.
There was no effect to applying fertilizer on seed yield.
This study was conducted at AL-buyarat AL-garbya, west Palmyra during
2010/ 2011 and 2011/2012 growing seasons to determine the optimum date and
plant density for sowing two faba bean varieties. The studied factors were two
sowing dates (15/10 and
5/11), plant densities (16.7 and 11.1 plants/m2) and two
varieties of faba bean (kobrusi and Hama1). Results showed that sowing on
early date 15/10 resulted in increasing plant height, number of branches/plant
and pod length as compared with 5/11 sowing date.
