أجريت تجربة حقلية خلال الموسم (2011-2012) 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/هـ) على شكل حمض البوريك , واربعة مستويات من الزنك (16, 0,8 ,24 كغ/ هـ )عل شكل سلفات الزنك أضيفت جميعها إل التربة عند تحضيرها للزراعة , وقد استخدم تصميم العشوائية الكاملة بثلاث مكررات , وذلك بهدف دراسة أثر مستويات مختلفة من البورون والزنك وتداخلاتهما في نمو نبات الذرة الصفراء وتطوره ومحتواها من بعض العناصر الغذائية . أخذت قراءات طول النبات , دليل المساحة الورقية , الوزن الرطب والجاف للنبات في ثلاث مراحل نمو هي : النمو الخضري , بداية الإزهار , ونهاية الإزهار . كما تم تقدير محتو الأوراق من العناصر الغذائية ( N,P,K,B,Zn,Mn,Fe,Cu )في المراحل السابقة , فضلاً عن مرحلة الحصاد.
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.

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.
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.
Field experiment was carried out at Research Station of the Faculty of Agriculture,
Muthanna University, Iraq, during 2014/2015 season, to study the effect of adding
NPK, biofertilizers Bacillus Subtilis and Glomus Mosseae on the growth and
yield
of maize (Zea may L.). The treatments were i.e control (zero: no vaccine),
biofertilizers Bacillus subtilis treatments, Glomus mosseae, both biofertilizers (F0,
F1, F2 and F3), respectively, Three levels of NPK liquid fertilizer i.e. 0, 5000, 7500
mg )C0, C1, and C2 respectively). The experiment design was RCBD with three
replications arranged according to split plot.
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.
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.
