تم تنفيذ البحث في منطقة جبلة خلال الموسم الزراعي (2012 - 2013م)ضمن بيت بلاستيكي بزراعة هجين الفليلفة الحلوة (فيغاريو) و هجين الفليفلة الحريفة (ايراد). تناولت الدراسة 6 معاملات للكثافة الزراعية مكررة 4 مرات لكل هجين . أظهرت نتائج الدراسة أن زراعة الهجين فيغاريو بأبعاد (50X60) سم قد أعطى أكبر عدد من الأزهار بلغت (18.33) زهرة/نبات، و أعطى أكبر عدد من الثمار في المعاملة (50X40) سم إذ بلغ عددها (20.98) ثمرة/نبات ،كما تفوقت المعاملة (50X40) سم بفروق معنوية على بقية المعاملات من حيث كمية الإنتاج المبكر (390.6)غ/م2 و الإجمالي بلغ (3486)غ/م2 .أما الهجين الحريف ايراد فقد أعطى أكبر عدد من الأزهار عند زراعته بأبعاد (50X40) سم حيث تفوقت هذه المعاملة على بقية المعاملات بفروق معنوية و بلغ عدد الأزهار (28.23) زهرة/نبات .و أعطت المعاملة (40X60) سم أكبر عدد من الثمار على النبات بلغ (107.17) ثمرة/نبات، و تفوقت أيضاً المعاملة (50x40) سم بفروق معنوية على بقية المعاملات و حققت أعلى إنتاجية في وحدة المساحة بلغت (9485.7) غ/م2.
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 applied 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.

This search aims to study the efficiency of using“Biotolerance” as a
fertiliser; by a foliar spry on Pepper seedling. Four varieties were
used (Marcony, California wander, Maroty-7 andRobber). The
results showed that the treatment by the fertilizer resulted in an
increase in growth thorough the plant length increasing.
The research was conducted in plastic green house for the 2013-2014, in Alqangerh
village, about 5 Km from the city of latakia, in order to study the effect of spraying the
leaves with some humic compounds and amino acids on growth and production o
f hybrids
of cucumber (Novo,Dorruk).
Spraying leaves with three organic fertilizers are (Huzone, Mol mixs), and two boats
Dbalin and Amino vega (an amino acid).
The results showed that all treatments of leaves spraying with organic fertilizer geve
better resultus with significant differences than the control treatment in all the studied traits
of both hybrids: (stem length, number of branches/plant, number of leaves/plant, leave area
cm2, the number of flowers on the stem, number of fruits on the stem, number of floral
branches, number of fruits on the branches).The treatment of spraying achieved with
mixture of humic compounds and amino acids increase with significant differences in both
the number of leaves/plant, number of branches/plant, the plant's stem length and number
of fruit on the stem in the hybrid Novo. while the treatment of spraying achieved of hiozon
increase with significant differences the number of branches/plant, the number flowers on
the branches and number of fruits on the branches was in the hybrid Dorok. As for the
early production and total production, the treatment of spraying with mixture of humic
compounds and amino acids with significant differences on other transaction when both
hybrids Novo and Dorruk amounted, respectivety (5 ، 4,1 kg/m2 ; 16 ، 14,8 kg/m2 ).
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.
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 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).
