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 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.

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.
The study was carried out at Abo Jarash farm, Faculty of Agriculture,
Damascus University, during the growing season of 2012, where the maize
cultivar "Gouta 1" was grown in three agricultural spacings (20, 30 and 40 cm
between plants in the same
row), with a fixed space (70 cm) between rows,
according to the randomized complete block design and three replicates per
treatment, in order to study the effect of the studied agricultural spacing on the
following characters: plant height, length and weight of ear, number of kernel
rows per ear, number and weight of kernels per ear, net percentage, hundred
kernels weight, the kernel yield, the dry yield and the oil and protein contents
in the kernels. Results showed a significant decrease in plant height from
155.31 to 130.10 cm, while a significant increase was observed in number of
kernels per ear (from 310.05 to 373.82 kernels), in weight of kernels per ear
(from 41.20 to 65.17 g) and in net percentage (from 61.61 to 91.51 %),
respectively with the increase of agricultural spacing from 20 to 40 cm.
However, the increase in these characters didn’t substitute the small number of
plants in the vast spacing compared with the narrow spacing, which is reflected
in kernel yield per unit of area that amounted to 3.19 and 2.04 tons/ha,
respectively.
The research was conducted during the growing season in 2013-
2014 in Bssiren Hama. In a split- plot design: the varieties were
main plots (asgro, rama, Muncipal) and the sowing dates were subplots (15\11;30\11;15\12 and 30\12) and the densities we
re subplots (20 plant\m2, 13.33 plant\m2). The early planting went to Significant increase in the days to germination, long time of fruit; the number of days to flowering and the number of days to fruiting; Plant height; Number of branches plant ; weight of pod; number of pods plant; dressing percentage; Yield of green pods plant and
Yield of green pods. While the high density was observed
Significant increase in the Plant height; Number of branches plant;
weight of pod; number of pods plant; and Yield of green pods
plant, while the low density was observed Significant increase in the Yield of green pods. The Asgro variety was obtained at Rama and Muncipal varieties in the number of branches plant; number of pods; Yield of green pods plant and, while the Rama variety was obtained by the plant height, and non- significant results were found among varieties by the weight of pod. The positive results also showed in the interaction among factors.
