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.
