هدف البحث إلى دراسة أثر التسميد الأخضر بنبات الترمس الأبيض و التسميد الحيوي بمعاملة بـذور
النباتات ببكتريا الريزوبيوم المثبتة للآزوت الجوي، و تأثير ذلك في بعض خصائص التربة و نمو محـصول
البطاطا و إنتاجيته و نوعية درناته في عروة ربيعية للموسمين الـزراعيين 2007/2008 و 2008/2009.
مادة 2 أظهرت النتائج أن نباتات الترمس التي لم تلقح بذورها بالريزوبيوم أسهمت في إضافة 75.3 كغ/م
، بينمـا أضـافت النباتـات الملقحـة بـذورها 2 عضوية خضراء (398 غ مادة جافة و 14 غ آزوت/ م
)، فضلاً عن دورها 2 مادة عضوية خضراء (581 غ مادة جافة و 3.22غ آزوت/م 2 بالريزوبيوم 55.4 كغ/م
في تحسين بعض خصائص التربة مقارنة بالشاهد، و من جهة أخرى تفوقـت نباتـات معاملـة التـسميد
الحيوي معنوياً على التسميد الأخضر في نمو نباتات البطاطا من حيـث وزن النبـات الجـاف و مـساحة
المسطح الورقي و دليله و ارتفاع النباتات و محتوى الأوراق من العناصر المعدنيـة (N،P،K،Ca،Mg)
فضلاً عن زيادة الإنتاج التسويقي من الدرنات و تحسين نوعيتها.
The effect of green manure and biofertilizer by using (Lupinus albus and
Lupinus albu s + Rhizobium) on some soil properties and potato growth and
production during two successive seasons of 2007/2008 and 2008/2009 was
studied. The results showed that green manure provided the soil with 3.75
kg/m2 green organic matter including (398 g dry matter and 14 g nitrogen),
while lupinus albus + Rhizobium provided the soil with 4.55 kg/m2 green
organic matter including (581 g dry matter and 22.3 g nitrogen) and improved
soil chemical properties. The results showed as well that biofertilizer significant
improved potato growth parameters: plant and tuber dry matter, foliage
surface, foliage index, plant length, plant elements content (N,P,K,Ca and Mg),
tuber number and their content of nitrate and protein .The results showed as
well that biofertilizer significant improved marketing potato yield.
