تأثير استخدام نسب مختلفة من السماد العضوي في نمو وإنتاجية نبات البندورة Lecopersicum Escolentum.L ضمن البيوت البلاستيكية
Abstract
نفذت الدراسة خلال الفترة 2008 - 2009 في منطقة بانياس ( بعمرائيل ) على نبات البندورة المزروع ضمن بيت بلاستيكي باستخدام مستويات مختلفة من التسميد العضوي (5% - 5% - 15 % - 20%) لتبيان تأثير هذه المعاملات على مجموعة من الصفات الفينولوجية والإنتاجية والنوعية .
تبين نتيجة الدراسة أن مستويات التسميد العضوي المختلفة قد أثرت بصورة معنوية في تطور طول النبات مقارنة بمعاملة التسميد المعدني وكانت أفضل المعاملات هي المعاملة بنسبة 20%, أما فيما يتعلق بعدد الأوراق, وعدد العناقيد الزهرية كانت النتائج متقاربة بين معاملات التسميد العضوي , وفيما يخص متوسط عدد الثمار والإنتاج لوحظ تفوق التسميد العضوي بجميع نسبه على التسميد المعدني ومعاملة الشاهد بينما لم تظهر هناك فروق بين مستويات التسميد العضوي , أيضا" تفوقت معاملات التسميد العضوي في تأثيرها في نسبة المادة الجافة وفيتامين C والحموضة على معاملتي الشاهد والتسميد المعدني .
This study was conducted during 2008 – 2009 growing seasons in the Banias area (Ba'amra'eel) on tomato planted in a plastic house by using different rates of organic fertilizing (5%, 10%, 15% and 20%) to show the effect of these treatments on the phonological, productive and qualitative properties.
This study showed that the different rates of organic fertilizing affected significantly the development of the plant length in comparison with the mineral fertilizer treatment; the best treatment was the 20% rate. However, regarding the number of leaves and the floral bunches, the results were approximately between the organic fertilizer treatments; while regarding the number of fruits and production average, it was noticed that the organic fertilizer was better than the mineral fertilizer and the control treatment; while there were no differences between the organic fertilizer rates, and the organic fertilizer treatments was better than the mineral and the control treatments in its effect on Vitamin C , the dry material and acidity .
