نُفّذت التجربة خلال موسمي 2009 و 2010 في بستان زيتون في محافظة ريـف دمـشق (منطقـة المعضمية) على صنفين من أصناف الزيتون (دان و نبالي محسن) بعمر 15سنة بهدف دراسة تأثير الرش الورقي بعناصر الآزوت و البورون و الزنك في نمو شجرة الزيتون و محتوى أوراقها من العناصر المعدنية. رشًت هذه العناصر منفردة أو مجتمعة مع عناصر أخرى على أشجار الزيتزن أربع مرات خـلال موسـم النمو في أوقات محددة بصورة محاليل لعنصر الآزوت (5غ/ل) منفرداً، حمض البوريك (2غ/ل)، سلفات الزنك (2غ/ل) منفردة، و بعنصرين معاً (آزوت + حمض البوريك) و (آزوت + سلفات الزنـك) و (حمـض البوريك + سلفات الزنك) و بالعناصر الثلاثة معاً (آزوت + حمض البوريك + سلفات الزنـك) و بـالتراكيز نفسها المطبقة بالرش المنفرد. حسبت متوسطات مساحة الورقة و طول الطرد و عدد الأزهار على الطـرد و عدد الثمار العاقدة و محتوى الأوراق من العناصر الكبرى K.P.N و عنصري B و Zn.
This experiment was carried out during 2009 and 2010 seasons in fields cultivated with 10 years of Dan and Nebaly cultivars of olive trees in province of Damascus to study the effect of foliar spray of to one of nitrogen (N), boron (B) and zinc (Z) on the leaf area, shoot length, number of flowers, leaves content of mineral elements, fertilization. These elements were sprayed individually or combined together four times during the growing season as follows: nitrogen (5 g/l), boric acid (2g /l), zinc sulfate (2g/ l), nitrogen + boric acid, nitrogen + zinc sulfate, Boric acid + Zinc sulfate, and nitrogen + boric acid + zinc sulphate) at the same rates in single spray.

the experiment was conducted under Syrian coastal conditions to investigate (Vicia
fabaL.), the effect of boron and zinc foliar fertilization on faba bean,either individually or
in combination, by increased rates (0, 0.25, 0.50, 0.75, and 1 kg boro
n / has boric acid, and
zinc at a rate of 0, 0.375, 0.750, 1.125, and 1.5 kg / ha as zinc sulfate). where fababeans
were plantedin plastic pots(15L) in )2013/11/10(and )2014/11/10(.The soil in pots has high
content of calcium carbonate, low boron and zinc content, with pH slightly basic
(representative of the region's soils).
Half boron and zinc fertilizer rates were sprayed after 33 days of germination and the
other half ,after 65 days of germination. The results showed significant responses in all
studied parameters (number of branches,number of pods / plant, weight of 100 seeds, and
seed yield (Kg. / ha) on faba bean plant, as a result of foliar fertilization by boron and zinc.
Fababeans response to boron is higher than to zinc fertilization in all studied
indicators. However,the treatmentB75Zn75(0.75 kg boric acid and 1.125kg of zinc sulfate)
is the best, as compared to others. Also, the driedseeds yield was increased by about
17.66%.
Field experiment was conducted during the season (2011-2012)at Bhanine village in Tartous city. Maize seeds of Ghouta 82 variety were planted in plastic pots filled with calcareous soil .Treatments including three levels of B( 0 , 3 , and 6 kg.ha-1)
as boric acid form and four levels of Zn (0 ,8,16 and 24 kg.ha-1) as zinc sulphate form added to the soil when it was preparation to farming , in a completely randomized block design with three replications, to study the effect of different levels of boron and zinc and their interactions on Maize growth and its contents of some nutrient elements . the readings that was taken plant length leaf area index ,wet and dry weight for plant in three growth stage: vegetative growth , start and end of flowering , stage , and evaluation concentration of N ,P , K ,B , Zn,Mn,Fe,Cu nutrients in the leaves at the back stages, in addition at havest stage.
This research carried out in Al- Bassa village at Lattakia province during 2013-2014, to determine the effects of increasing rates of boron and zinc fertilization by foliar spraying, on root nodulation and seed yield of broad beans (Viciafaba L.). Se
eds were planted in plastic pots (15 kg capacity), filled with sandy-silty soil, characterized by its poor content of boron, and represents most of lands in the region. Boron and zinc were sprayed by five increasing concentrations (Bo, B25, B50, B75 and B100) and (Zno, Zn25, Zn50, Zn75, Zn10)on broad bean plants at 33 and 65 days post-emergent. Results showed that treatments high significance than control, in termsof root length witch the best treatment was B100Zn100with 31c.m, and 2.85 g for B75Zn75 as a wight of length, on the other hand the best treatment for number of nodules was B75Zn75, 179.03 c.m, B100Zn100 was the best for height of the plant with 100.20, for protein B100Zn100 the best with 37.4%, However, boron and zinc fertilization treatment B75Zn75 is the best, economically.
The study was carried out in apple orchard and at the laboratories of Agricultural
Scientific Research Center, and Pome and Grapevine Division in Sweida (GCSAR),
Syria, during the growing seasons of 2015 and 2016 to study the effect of organic
res
idues, and boron and zinc addition on some soil characters, fruit set ratio and
some fruits qualitative traits in Starking delicious apple cultivar in Sweida.
Sour orange (Citrus aurantium L.) seedlings were sprayed three times a
season with four levels of urea (45 % N) (2.5, 5.0, 7.5 and 10.0 g/L) and two
levels of ascorbic acid (150 and 300 g/L), each alone or in combinations.
Meanwhile the seedlings
of control treatment sprayed with distilled water
during 2010 growing season, twenty days intervals between each spray and
another. Results obtained at the middle of October of the same season,
indicated that the foliar spray with urea at the concentrations of 5.0, 7.5 and
10.0 g/L significantly increased leaves N and chlorophyll concentrations, leaves
number, seedling leaves area, seedlings height, main stem diameter and leaves
fresh and dry weight, especially at the foliar spray with 10.0 g/L. The means of
these parameters were 3.19%, 66.80 SPAD, 146.66 leaves/seedling, 3700.00
Cm², 83.66 Cm, 4.50 mm, 4.70 g, 1.53 g, respectively. Meanwhile ascorbic acid
spray at two concentrations unsignificantly affected all parameters, except
leaves chlorophyll content, leaves number and seedling leaves area. Most
treatments of combinations spray with urea and ascorbic acid significantly
affected all studied parameters, especially the treatment of foliar spray of urea
and ascorbic acid at a concentration of 10.0 g/L and 300 mg/ L, which gave the
highest means of leaves N concentration, leaves number, seedling leaves area
and leaves fresh and dry weights, and it unsignificantly differs from the
treatments which gave the highest means of seedlings height, main stem
diameter and percentage of leaves dry matter weight .
