Abstract

هدف البحث إلى محاولة تحديد المعادلة السمادية المثلى من الأسمدة الكيماوية والعضوية لأشجار العناب الصيني (الصنف الحفاوي)، من خلال استخدام عدة معاملات سمادية  وأظهرت الدراسة النتائج التالية :

1- تفوق معاملات التسميد معنوياً على معاملة الشاهد في معظم الصفات الثمرية المدروسة (نسبة العقد – نسبة تساقط الثمار- الإنتاج).

2- أعطت المعاملة السمادية التالية :  10كغ سماد عضوي (زبل بقري متخمر) للشجرة و800)غ N + 800غ P2O5 + 200غ K2O) للشجرة، بواقع 1N= 800g، أعلى نسبة عقد (6.35%) وأكبر إنتاج للأشجار     (6.73كغ/الشجرة) والتي تفوقت معنوياً على الشاهد وعلى باقي المعاملات السمادية المدروسة (T1,T2,T3.T4.T6)، والتي حققت نـسبة عقد (1.93,2.74,3.93,3.53,3.71)% على التوالي، أما الإنتــاج فكان (0.93,2.11, 5.71,4.72,5.93) كغ / الشجرة على التوالي، وذلك بالنسبة لأشجار العناب الصيني بعمر   (7- 8) سنوات والمزروعة في المنطقة الساحلية.

This study tries to determine the optimal equation of chemical and organic fertilization of ziziphus jujuba trees (Havawi variety), using several fertilizing treatments . Results show:

  1. Superiority of fertilization treatments regarding characteristics of studied fruit (fructify rate-drop of fruit- product) compared to the control.
  2. The following fertilizer equation (10 kg fermented cow dung) + ( 1N: 1P:1/4K)/Tree ,1N=800g, gave the best fructify rate (6.35%) and greater produce(6.73Kg/tree) compared to the remaining fertilizer treatments, (T1,T2,T3.T4.T6)   which prove fructify rate (0.93, 2.11, 5.71, 4.72, 5.93) %  respectively, and produce  (1.93,2.74,3.93,3.53,3.71)kg/tree respectively. The study was applied to 7 years-old Jujube trees, planted in coastal area.
