هدفت الدراسة إلى تقويم فعالية ثلاث طرائق لتعقيم التربة في مكافحة بعض الفطور الممرضة للنبات في البيوت المحمية شملت: التعقيم الكيميائي بالفورمالين و التعقيم الشمسي + التسميد العضوي و التعقيم الشمسي, و عند أعماق 0 - 5, 5 - 10 , 10-15 و 15- 20 سم .
The study was carried out to comparison between of of three controlling treetments, of soil-borne fungi in greenhouses. The treetments were as follows: An treeted control, Formalin 3%, soil Solarization + animal manur and solarization for 50 days, and 0 , 5, 10 ,15 and 20 cm depth.

This investigation was carried out in a plastic house (350 m² area) located at Tishreen
University in two seasons 2007-2008 and 2008-2009, to study the effect of soil solarization
in soil borne fungi in greenhouse. With four treatments: the control
treatment,
Soilsolarization: 30, 40, and 50 days, and 0, 5, 10, 15 and 20 cm depth. The solarized soil
covered with transparent polyethylene.
In the summer of ١٩٩٨ at the Kearney Agric. Center-University of
California, two experiments were carried out to evaluate solarization methods
for disinfestation of nursery soil from soil born fungi and nematodes. On
rototilled sandy loam soil, ٢m
٢ x ٢٠cm high beds were shaped into place, each
experiment had ٥ treatments with ٣ replications, tow treatments received the
double tent over black or silver plastic. The other ٢ treatments had single tent.
In addition, a nontreated control was placed in the shade.
In order to evaluate the important role of climate on soil formation, three
different locations (Nawa, Dael and Nasib) in southern part of Syria,
representing the North West, Middle and Southern parts of Hauran Plateau
were selected and differ mai
nly in the amount of annual precipitation and
relatively with other factors. Three profiles, replicated three times, were
prepared one profile for each area.
This study was conducted in Abu-Jarash farm at the Faculty of Agriculture,
Damascus University during the main season 2013 to evaluate the effect of soil
solarization and organic fertilization treatments on the productivity of some
maize genotypes
(Basel 1, Basel 2, Ghouta 1, Ghouta 82 and Local White). The
experiment was laid out according to split-split plot design with three
replications. The statistical analysis results clearly indicated to the existence of
variability in the response of studied maize genotypes to soil solarization and
organic fertilization treatments. The genotype Ghouta 82 surpassed in the traits
of plant height, leaf area index, 100-kernel weight and grain yield (150.25 cm,
2.84, 28.10 g and 7.99 ton.ha-1) respectively, as compared to other studied
genotypes and was closely followed by the genotype Basel 2 which recorded the
highest number of rows per ear (13.83 row/ear). Soil solarization for 45 days
before sowing and applying organic manures at the rate of 20 ton.ha-1
encouraged the traits of plant height, leaf area index, number of rows and
grains per ear, 100-kernel weight which was reflected on grain yield. Therefore
we can grow variety Ghouta 82 or hybrid Basel 2 to get higher yield of maize.
Root rot is considered one of the serious widely spread tomato diseases in
plastic houses culture of Syria. Soil solarization, using transparent polyethylene
(PE) covering, was applied during July and August (١٩٩٤-١٩٩٦) in Tartoos
governorate for
controlling soilborne pathogenic fungi. Results indicated that,
native fungal populations in covered moist soil supplied with or without sulfur
were significantly reduced in comparison with the uncovered treatment.
