نفذت تجربة زراعة محصول الذرة الصفراء .Zea mays L صنف برشلونة في أصص بلاستيكية باستعمال تربتين مختلفتين (إحداهما تربة القرنة الفقيرة بالمادة العضوية و الأخرى تربة أهوار ميسان الغنية بالمادة العضوية). و ذلك لبيان تأثير السيلنيوم و الكبريت و الفوسفات و التداخل بينهما في الوزن الجاف للمجموع الخضري لمحصول الذرة الصفراء. حيث أضيف السيلنيوم بأربعة مستويات (0 ، 10 ،20 ،40) غ Se /هـكتار Na2SeO4، و الكبريت بثلاثة مستويات ( 0، 30 ، 60 ) كغ S /هـكتار على صورة K2SO4 ، و الفوسفور بثلاثة مستويات (0 ،60 ،120 ( كغ P /هـكتار على صورة سماد سوبر فوسفات المركز.
An experiment was conducted on maize crop (Zea mays L.) in plastic pots in two
different soils (Qurna soil, which is poor organic matter and the other soil from
Maysan marshes, which is rich in organic matter), to study the effect of selenium,
sulfur and phosphate and their interaction on dry weight of shoot of maize crop.
Selenium was added at four levels (0, 10, 20 and 40 g Se ha), sulfur at three
levels (0, 30 and 60 kg S ha), and phosphorus at three levels (0, 60 and 120 kg P
ha).
