تضمن البحث دراسة أثر معاملة التربة الرملية بالبوليمير (الهيدروجيل) بتراكيز (0,1غ/كغ-0,2غ/كغ) في معدّل الإرتشاح في التربة الرملية, و دراسة أثر معاملة التربة الرملية بتراكيز ( 0,1-0,2)غ/كغ من الهيدروجيل و عند مستويين من الرطوبة 80% و 100% من السعة الحقلية في مؤشرات نمو نبات الفليفلة. أظهرت نتائج البحث أن معاملة التربة الرملية بالهيدروجيل (0,1غ/كغ-0,2غ/كغ ) أدت إلى تخفيض معدل الإرتشاح بنسبة 41.1% و 50.9 % على الترتيب مقارنة مع الشاهد و معاملة التسميد, كما أظهرت نتائج البحث زيادة كل من نسبة الإنبات و ارتفاع النبات في معاملات البوليمير مقارنة مع الشاهد و معاملة التسميد المعدني فقط و قد زادت مساحة المسطح الورقي, و زاد الوزن الجاف لكل من الفروع و الجذور و بفروق معنوية مقارنة مع الشاهد و معاملة التسميد فقط, و لم تكن هناك فروق معنوية في المعاملة الواحدة عند مستويي الرطوبة 80 و 100% من السعة الحقلية . أدت معاملة التربة الرملية بالهيدروجيل و بتراكيز (0,1غ/كغ-0,2غ/كغ ) إلى تخفيض كمية الماء اللازم لإنتاج وحدة الوزن من المادة الجافة للفروع بنسبة قدرها 50 و 65% مقارنة مع الشاهد.
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 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 experiment was carried out to assess the germinability and seedling
growth rate of some treated vegetable seeds (i.e. onion, carrot, and tomato) with
aerated - aqueous solutions.
Seeds were treated for 24 hours with 0.1% of both succinic acid
and
nutrient solution, and the seeds to medium ratio was 1:5.
The soaking solution was continuously aerated by an air pump. At the end
of treatment, the seeds were dried up at room temperature to eliminate the
excess superficial moisture.
The research aimed to study the effect of size of container on the growth of
seedlings pepper "Snapper". Two different sizes of plastic containers, with
dimensions 8×8 cm and12×12 cm were used, Results showed that the use of
containers with large
dimensions had increased the growth of seedlings
compared with the use of smaller ones. A significant increase, of about 14%
was observed in the average length of seedlings and about 16% in the average
number of leaves produced in the large containers as compared with seedlings
produced in smaller ones. Also the fresh wet weight, whether for the plant or its
separate parts was significantly higher in seedlings produced in the large
containers. The plant fresh wet weight in the large container was 26.98 g vs.,
2.27 g in the smaller ones.
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.
