This research work aimed to study the effect of different mixtures of growing media
on pepper seedlings and their ability to withstand transplanting shock.The variety QarnAlgazal
of pepper and five mixtures of growing media were used.The mixtures i
ncluded bitmoss
alone,bitmoss with equal volume of soil or sand,soil and cow manure in a ratio of
1:2,and cow manure with soil and sand in a ratio of 1:1:1.
The experiments were implemented in aplastic green house without heating in the
nursery farm of the faculty of Agriculture,Tishreen University.The completely randomizel
design was adopted with three replications for each treatment and 15 plants for each replication.
The results showed that themedia containing cow manurewere the more effective ingrowth
of sapling as represteded by the increased hieght of sapling, number and area of
leafs,fresh weight of both biomass and roots of sapling.The effect was very clear in the
media containing cow manure and soil in the ratio of 1:2.
The study was conducted in Jableh during 2012/2013 in plastic green house on sweet
and hot pepper hybrids to study the effect of plant density on growth and productivity.
The hybrid VIGARIO(sweet pepper) and hybrid ERAD (hot pepper)variety were
ap
plied in six treatment and four replication .It was showed that the highest number of
flowers were recorded in VIGARIO variety in space (50x60)cm to amount(18.33)
flower/plant ,while the the highest number of fruits were recorded in space(50x40)cm to
amount(20.98)fruit/plant and the earlest yield (390.6)g/m2and the highest total
(3486)g/m2productivity were found in space (50x40)cm . IRAD hybrid give the highest
number of flower in space (50x40)cm to amount(28.23) flower/plant,while the hieghest
number of fruit were recorded in space (40x60)cm to amount(107.17) fruit/plant and the
highest productivity were found in space(50x40)cm to amount (9485.7)g/m2.
The effect of sandy soil treatment with superabsorbent polymer(0.1,0.2g/kg)on
infiltration rate and shoot and root growth of green pepper at two soil levels (80and
100%)of field capacity was studied.
The results indicate that sandy soil treatment
with polymer (0.1 and 0.2
g/kg)decreased infiltration rate by 41.1 and 50.9% alternatively compared to the control.
Germination rate, plant height ,leaf area, shoot and root dry weight were increased
significantly with polymer treatment compared to the control and mineral fertilization
treatment ,but that difference was not significant among field capacity levels (80and 100%)
Treatments with hydrogel (0.1,0.2g/kg)decreased water need to produce a unity of
shoot dry matter and economized water by 50 and 65%compared to the control.
This study has been carried out using the onion and pepper seeds to
determine the effects of the aqueous medium temperature, during treatment
with oxygen, on the germination percentage seed vigor and for determining the
period needed for the treat
ment with the oxygen as well.
The treatment period has taken ١٢-٣٦ hours according to the kind of crop
and the medium temperature, which varied between ١٠-٣٠ °C.
Results of the study indicated that the treatment of seeds with oxygen, in an
aqueous medium, improved the germination percentage and the seed vigor. The
period needed for the treatment of the seeds with oxygen differs according to
the kind of crop and the temperature of the medium and varies between ١٨-٢٤
hours with respect to the onion seeds, and between ٢٤-٣٦ hours regarding the
pepper seeds. The period needed for treatment with oxygen decreases with the
rise of temperature.
This study is aimed at studying the effect of using four species of
bacteria Plant Growth Promotion Rhizobacteria (PGPR) Azotobacter
chroococcum, Rhizobium leguminosarum, Bacillus megaterium and
Frateuriaaurantia on the growth, yield and reducing
the effect of
Cucumber mosaic virus(CMV) on pepper plants in a greenhouse
experiment. The observed growth parameters were: plant height, foliage
fresh weight, root fresh weight, fruit weight in a green house expirment
in Tartous in the season 2016/2017.
This research on pepper crop conducted to impact water stress using
three transactions water are: full irrigation (100% from water
requirement), 0.75% of full irrigation, and 60% of full irrigation,
has been designed experiment in a way random sectors full, use a
variety of municipal plant peppers, and used drip irrigation method.
