نفذ البحث خلال المواسم 2007 و 2008 و 2009 على أشجار العنب صنف حلواني بعمر 10 سنوات لدراسة تأثير التسميد المعدني و عمق إضافة سماد السوبر فوسفات في بعض مؤشرات النمو و مواصفات ثمار العنب، استعملت ثلاثة معدلات من السماد المعدني (K. P. N) هي: (75 كغ N/ هــ + 25 كـغ P2O5/هـ +50 كغ K2O/هـ)، و ضعفاه و أربعة أضعافه في ثلاثة مكررات علاوة على الشاهد، و أضيف ثلاثي سوبر فوسفات نثراً على السطح و في خطوط على عمق 30 سم، حسبت متوسطات مساحة الورقة و طول الطرد و درجة تلون الثمار و صلابة الثمار، لوحظت زيادة معنوية في مساحة الورقة و طول الطـرد و درجة تلون الثمار في المعاملات المسمدة مقارنة بالشاهد، و كان أفضلها المعدل الثالث من حيث مساحة الورقة و طول الطرد، و المعدل الثاني و الأول من حيث درجة تلون الثمار في حين لوحظ انخفاض معنـوي في صلابة الثمار بازدياد معدل التسميد، كما لوحظت زيادة معنوية في مساحة الورقة بنسبة 11 % و طول الطرد بنسبة 5.4 % في معاملات التسميد الفوسفاتي العميق مقارنة بالسطحي.
The research experiment was carried out during the 2007, 2008 and 2009, seasons on grape variety Al- Helawani (10 years old) to study the effect of N.P.K. fertilization rates and the triple superphosphate (T.S.P) application method on some fruits characters and growth indicators. Three fertilization N.P.K rates were used, rate 1 (75:25:50) kg/ ha, twofold and fourfold of rate 1, in three replicates in addition to control. The application of (T.S.P) was on soil surface and at 30 cm depth, the percent of leaf area, shoot length, the degree of berry colour, berry firmness were calculated. The results showed a significant increase of leaf area, shoot length and the Berry colour compared to control. The third rate was the best for increasing the leaf area and shoot length, while the first and second rates were increased the colour of Berry. At the same time, there was a gradual significant decrease in Berry firmness compared to control when the rate of fertilizer was increased. It was also noted a significant increase in leaf area (11%) and shoot length (4.5%) in deep T.S.P application compared to the surface application.

The research experiment was carried out during the 2007, 2008 and 2009
seasons on grape variety Al- Helwani (10 years old) to study the effect of NPK
fertilization rates and the triple superphosphate (T.S.P) application method on
some fruits chara
cters.Three fertilization NPK rates were used, rate 1
(75:25:50) kg/ ha, twofold and fourfold of rate 1, in three replicates in addition
to control. The application of (T.S.P) was on soil surface and at 30 cm depth.
The results showed significant increase of the total soluble solids (TSS), pH and
vitamin C compared to control. while the content of TSS in juice increased by
40.9%, 44.6%, 50.3% in the three rates, respectively, compared to control, pH
increased from 5.45 in control to 5.92; 5.89; 5.73 in the three rates,
respectively, in turn, significant decrease in total acidity (TA) was noted by
15.3, 11.1 and 42.8%, in the three rates, respectively, compared to control.
ASignificant increase of (TSS) by 2.5% and vitamin C by 10 % in deep T.S.P
application compared to the surface application, on the other hand, (TA)
decreased significantly by 4.2%, while, there was no significant differences in
pH, in both treatments.
This research was carried out through the 2012-2013 season on 10 years old, grafted on the rootstock B41,grapevines of Al-Hulwani cultivar. Three levels (10,20,40 t/ha) of organic fertilizers of cow, sheep plus and poultry were used, in addition to
three treatments from mixture of this levels (3.33,6.66,13.32 t/ha) for one type of the fertilizers. The research also included three treatments from mixture of mineral fertilization with (N,P,K) at the rate (1:1:1) by using urea 46%, super phosphate 46% and potassium sulphate 50% in three levels (100-200-400 kg/ha), in addition to the control without fertilization, to study their effects on Some quantitative and qualitative Characteristics of the grapevine cultivar Al-Hulwani. The results showed the following:
The use of organic and mineral fertilization gave in all levels and types superiority in all studied characteristics compared to the control.
Most levels of organic fertilization and its treatments are superior to mineral fertilization in all studied characteristics.
The first level of sheep plus (10 kg/ha) gave the better results in weight of cluster and quantity of product, but the first level of poultry gave the better results in weight of 100 fruits.
The use of organic manure was with positive effect on fruits color and was superior to mineral fertilization.
The yield/vine increased significantly from 65.77kg/vine to 118.5 and 97.8kg/vine when the low level of sheep puls the mixture of the medium levels of mineral fertilizers were used.
The aim of this research is to determine the role of mineral (NPK) and organic fertilization (Chicken manure, Cow manure and Chicken with Cow manure) on vegetative growth and flowering of Zinnia (Zinnia elegans). This research also examines the possi
bility of relying on this organic manure to present nutrients for the plant in order to reduce mineral fertilization.
The results show that the use of NPK (30, 20, 20 g/m2) or Chicken manure (2Kg/m2) has a positive impact on vegetative growth (plant height and average number of branches andleaves on the plant). They also show a positive effect on the flower developmentand flowering (early flowering, number of flowers and flower volume). These positive effects are reflected on the proportion of dry matter both in the vegetative and flowering part. The results indicate that plants fertilized with NPK or Chicken manure realize higher economic profit than the control and those fertilized with Cow manure.
The research was carried out at Jeb Ramlah Research Station – AlGhab Research Center -
General Authority of Scientific Agricultural Research at 2017 growing season. The
objective was to investigate the effect of three organic and bio fertilizers (B
acillus, Humic
acid and Amino acids) and three fertilization methods (Soaking seeds, Vegetative spraying
and Plant irrigation) in some morphological and production traits of cotton cultivar 124
(Gossypium herutum L.) The experiment was conducted according to RCBD with three
replications. The first factor (fertilizer type) occupied the main plots, while the second
factor (fertilization method) occupied the split plots. Statistical analysis was carried out
using the Genestat.12 software and the least significant difference L.S.D. at 5% level was
calculated. Studied traits included (at the beginning of Blooming stage): Plant Height,
Plant wet weight, Plant dry weight, Leaf area and plant production of cotton. The results
showed that the average of treatment of amino acids was superiority significant on the
others in terms of plant height (70.70cm), Plant wet and dry weight (201.50, and 83.41g),
respectively, Leaf area (4240.15cm2/plant) and plant production of cotton (75.13g). For
fertilization method, Vegetative spraying average was superiority significant on the others
in terms of all studied traits.
In this study, the effect of different concentrations of sodium chloride
(NaCl) (0, 50, 100, 150 mM) on some physiological characteristics and some
growth indicators of SO4 grape rootstock propagated in vitro was studied at the
laboratories of Gen
eral Commission for Scientific Agricultural Research
(GCSAR), Damascus/Syria. Results indicated that the increase of NaCl
concentration up to 100 mM in culture medium led to reduce the growth
indicators (survival plants, average of the plant length and average number of
buds) with significant differences when compared with the control plants after
4 weeks from culturing on multiplication media, while treatment with 150 mM
of sodium chloride led to death of all plants. Using the concentrations 50 and
100 mM of NaCl also caused decreasing the total chlorophyll content in the
leaves.
