عوملت نباتات الفريز التابعة للصنف Grande Oso بثلاثة أنواع من الأسمدة الورقية التي تحتوي على (الآزوت أو البورون أو المنغنيز) منفرداً أو مشتركاً فضلاً عن معاملة بعضها باليوريا سماداً أرضـياً، و تركت نباتات أخرى شاهداً، و اِستُعملت ثلاثة تراكيز من الأسمدة.
Strawberry plants of Oso Grande variety has been treated with three types of foliar fertilizers containing (Nitrogen, Boron, Manganese) individually and combined, in addition to treating some of them using urea as soil fertilizer. Some plants were untreated to be used as a control. Three concentrations were used.

دراسة ومقارنة تأثير الأسمدة الحيوية والفوسفورية والبوتاسية في نمو وانتاج نباتات الفريز Fragaria ananassa
A field experiment was carried out to investigate the effects of organic
fertilizers (mushroom substrate residues, poultry manure and city compost)
and mineral fertilizers (NPK) on some properties and productivity of a
calcareous soil using chard
(Beta vulgaris) as a test crop. The plant was
cultivated at spring season 2009. The first cut was after 60 days of swing. The
results of experiment were: The NPK fertilizer significantly affected dry weight
of plant yield (157.6g/m2soil) and the efficiency of fertilizer in productivity was
50.8% compare to control (104.5g/m2soil). The treatment of 50% NPK + 50%
poultry manure gave the highest yeld compare to other treatments. However
the organic treatments did not differ significantly among them. Concentrations
of NPK nutrients in plant leaves were as follows: NPK > 50% NPK + 50%
poultry manure > poultry manure > 50% NPK + 50% mushroom substrate >
mushroom substrate > 50% NPK + 50% city compost > city compost. The
organic fertilizers decreased the NPK in plant and soil compare with NPK
fertilizer treatment. However there was no significant differences between NPK
treatment yield and 50% NPK + 50 % poultry manure treatment. It was
concluded that the use of 50% NPK +50 % orgnic fertilizer (specially poultry
manure) was important to get best result.
The research was carried out in the laboratories of food science department
at Faculty of Agriculture, Damascus University during the year 2012 to
compare some chemical parameters (moisture،ash, sugars, fat, fibe, protein)
and biological active co
mpounds (total phenols, vitamin C) in fresh strawberry
fruits and strawberry jam. Statistical analysis showed a significant reduction
(p<0.05) in moisture, ash, fat and protein in strawperry jam comparing to fresh
fruits. Total phenols was decreased significantly (P< 0.05) from 2078 mg/100 g
DM in fresh strawberries to 1070 and 962 mg /100 g DM in homemade and
commercial strawberry jam respectively. Also the amount of vitamine c was
decreased from 346 mg /100 gram dry matter in fresh fruits to 45 mg/100 gram
dry matter in locall made jam ،while it was 30 mg/ 100 gram dry matter in
commercial strawberry jam. These were reflected on anthocyanins which was
decreased from 1080 mg/ 100 g DM during processing to 132 and 105 mg/ 100 g
DM in homemade jam and commercial strawberry jam respectively. These
changes reflected in a significant (P< 0.05) decline in the antioxidant activity.
this search has studied to know the effect of addition of three
resources (cows, sheep and poultry) and five levels (0, 7.5, 15.0,
22.5, 30.0) T/h, in some physical properties of soil, and some
characteristics of wheat, class Sham- 4. soil was sel
ected from (0-
30) cm of Ayash village in Dier AZ zour - sandy soil texture. The
experiment carried out in a pot capacity (9) kg using a (RCD) with
three replications.
This research was carried out through the 201-2011 and 201-/2012 seasons
on 26-year-old trees of AL– Ashouri Pistachio cultivar grown in clay soil, in a
private orchard in Souran region (Hama province). Four types of organic green
fertilizers (Len
tils, Vetch, equal mixture from Lentils and Vetch and mix of
these legumes with barley), in addition to the control, to study their effects on
some quantitative and qualitative characteristics of pistachio nut. Results
showed that the use of green fertilizers caused significant increase in studied
indicators and the best treatment was mix of legumes with barley (45% Lentils,
45% vetch, 10% Barley), which achieved the highest significant values، where
average of weight of the 100 nuts was 107.45 g during the two seasons, the
average of weight of the 100 kernel was 67.08 g, average of length of shell was
20.85mm and an annual yield was 32 kg/ tree, compared with control, which
achieved 87.50g, 40.25g, 18.08 mm and 16.75 kg, respectively.
