نُفّذ البحث في مركز البحوث العلمية الزراعية بالقامشلي، التابع للهيئة العامة للبحوث العلمية الزراعية بسورية، في منطقة الاستقرار الأولى، خلال المواسم الزراعية 2011 و 2012 و 2013 بهدف معرفة تأثير إضافة مستويات مختلفة من الزيوليت الطبيعي (20-T2 طن/هكتار، 40 -T3طن/هكتار، بالإضافة إلى معاملة الشاهد بدون إضافة T1)، في إنتاجيّة القمح ضمن دورة زراعية ثنائية قمح/حمّص و في محتوى الطبقة السطحية للتربة من الآزوت، و الفوسفور، و البوتاسيوم المتاح. نفّذ البحث باتباع تصميم القطاعات العشوائية الكاملة، بثلاثة مكررات لكلّ معاملة.
The research was carried out at Al-Qamishli Agricultural Research Center, GSAR,
Syira, during the seasons 2011, 2012 and 2013, in order to estimate the effect of
adding different levels of a crude Zeolite (T2-20 tons/ha, T3- 40 tons/ha, in addition
to the control (without adding Zeolite T1), on wheat productivity within a bilateral
crop rotation was followed, consisted of wheat and chickpea, and on the content of
nitrogen, phosphorus and potassium in the surface layer of the soil .The research
was conducted using Complete Randomized Block Design with three replicates.
