أجريت تجربة حقلية خلال الموسم (2012 - 2011) بزراعة الذرة الصفراء صنف غوطة 82 في تربة كلسية معبأة في أصص بلاستيكية في قرية بحنين التابعة لمحافظة طرطوس.تضمنت المعاملات ثلاثة مستويات من البورون (3 ,0 و 6 كغ/هـــ) و أربعة مستويات من الزنك 16,8,0) و 24 كغ/هـــ) أضيفت جميعها إلى التربة ،و استخدم تصميم العشوائية الكاملة بثلاثة مكررات، و ذلك بهدف دراسة أثر مستويات مختلفة من البورون و الزنك و تداخلاتهما في محتوى نبات الذرة الصفراء من بعض العناصر الغذائية. أظهرت نتائج البحث أن تأثير مستويات مختلفة من B و Zn و تداخلاتهما في التربة كان واضحاً في محتوى الورقة من المنغنيز و الحديد و النحاس. كما أن وجود الزنك بكميات عالية في التربة كان له تأثير واضح في خفض محتوى B في الأوراق و زيادة محتوى K فيها. كذلك لوحظ أن وجود البورون في التربة ساعد على زيادة محتوى الآزوت في الأوراق. و كان للتداخل بين الزنك و البورون تأثير مهم في محتوى الأوراق من الزنك، بينما لم يكن لتطبيق الزنك و البورون تأثير مهم في تركيز الفوسفور في الأوراق.
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) and four levels of Zn (0, 8, 16 and 24 kg.ha−1) added to the soil, 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 content of some nutrients. Results of this study showed that there was a clear effect of B and Zn and their interactions in soil on leaf content of Mn, Fe and Cu. High amounts of zinc in the soil had a clear effect on reduced leaves content of B and increased its content of K. The presence of a of B in the soil, assisted to increasing of leaf N content. There was a significant effect of B and Zn interaction on leaf content of Zn, and no effect on leaf P content.

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 aims to study the proteins transformation in zea maize plant
seedlings cells, (GHOTA 82) under the influence of phyto hormone Auxin &
grothregulators 2,4-D and IBA.
Maize plant seeds were germinated in water medium for six days in
d
arkness and temperature of 25 ºC.
The quantity different groups of proteins, were analyzed in the stem cells of
the developing seedling mesochotyles after incupation in darkness water and in
different solutions of auxin, 2, 4D & IBA (in concentration 50 mg/l) for 20
hours in 26 ºC.
The results showed that had inhibition effects on hydrolysis of protein
groups in zea maize plant seedlings cells.
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%.
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.
Objective of this work was to investigate how plant density and nitrogen
rate affects the growth , yield and its components in maize (Bassel 2 hybrid).
The experiment was carried out, at the agricultural research centre in Snoubar
Jableh, during t
he 2008 and 2009 seasons, included 12 treatments which were
the combination three plant population densities 71428/ha, 57142/ha, and
47619/ha and four N rates (0, 60, 120 and 180 kg/ha). The experimental design
was a split-plot, with different densities as main plots, randomized in three
complete blocks, and the fertilization as subplots. The data were analyzed by
using “Mstat” statistical package. Increasing planting population density
delayed anthesis and silking date, increased the anthesis-silking interval, plant
height, ear height, grain yield, agronomic nitrogen efficiency and nitrogen use
efficiency, but decreased ear leaf area, chlorophyll content, 1000 seed weight,
number of grains/ear, shelling percentage (%), and grain protein content.
Nitrogen fertilizer decreased tassilling and silking date, and nitrogen use
efficiency, increasing plant and ear height, ear leaf area, chlorophyll content,
number of grains/ear, ear weight,1000-grains weight, Shelling percentage,
grain yield up to 120 kg N/ha, agronomic nitrogen efficiency and grain protein
content.
