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.

Research summary
تدرس هذه الورقة تأثير السماد الأخضر والسماد الحيوي باستخدام (Lupinus albus وLupinus albus + Rhizobium) على بعض خصائص التربة ونمو وإنتاج البطاطا (Solanum Tuberosum.L) خلال موسمين متتاليين 2007/2008 و2008/2009. أظهرت النتائج أن السماد الأخضر زود التربة بـ 3.75 كجم/م² من المادة العضوية الخضراء بما في ذلك (398 جرام من المادة الجافة و14 جرام من النيتروجين)، بينما زود Lupinus albus + Rhizobium التربة بـ 4.55 كجم/م² من المادة العضوية الخضراء بما في ذلك (581 جرام من المادة الجافة و22.3 جرام من النيتروجين) وحسن الخصائص الكيميائية للتربة. كما أظهرت النتائج أن السماد الحيوي حسن بشكل كبير معايير نمو البطاطا: المادة الجافة للنبات والدرنات، سطح الأوراق، مؤشر الأوراق، طول النبات، محتوى العناصر في النبات (N,P,K,Ca,Mg)، عدد الدرنات ومحتواها من النترات والبروتين. كما أظهرت النتائج أن السماد الحيوي حسن بشكل كبير إنتاجية البطاطا التسويقية.
Critical review
دراسة نقدية: تقدم هذه الورقة بحثًا مهمًا حول تأثير السماد الأخضر والسماد الحيوي على نمو وإنتاجية البطاطا. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من المفيد تضمين تحليل اقتصادي لتكلفة وفوائد استخدام هذه الأسمدة مقارنة بالأسمدة التقليدية. ثانيًا، يمكن أن تكون الدراسة أكثر شمولاً إذا تم تضمين تأثيرات السماد الحيوي على المدى الطويل على خصائص التربة. أخيرًا، كان من الممكن تحسين الورقة بإضافة المزيد من التفاصيل حول المنهجية المستخدمة في قياس وتحليل البيانات لضمان تكرار النتائج من قبل باحثين آخرين.

Effect of organic and bio fertilizers (Azotobacter and phosphate solubilizing bacteria) on production of potatoes and some soil properties was studied in Tartous. The experiment consisted of 4 treatments (control soil, soil+manure, soil+ bioferti lizer and soil+manure+biofertilizer) each replicated four time, for 2004 and 2005 seasons. Total N, available P, available K, and organic matter in soil were determined. Significant increases were observed in most of the inoculated and organic fertilized treatments compared with the control. However, the treatment (soil+manure+biofertilizer) was the best and showed significant increases in potato yield compared with other treatments especially in the next season. However, the second season was better in yield increase in all treatments than the first seacon.
The effect of different levels(5,7.5 and 10 ml/L) of EM1 on potato growth and productivity was studied, using complete randomized design with 4 treatments. Potato plant (cv.spunta) were grown in nursery garden of tishreen university 2016. The resu lts showed that foliar spray of potato plants with EM1 had a positive effect on studied parameters . Spraying plants with 10 ml/L of EM1 gave a significant increase in leaf area, plant high, number and weight of tubers and total yield.
The study was carried out at Tishreen University nursery during the spring of 2015 in order to evaluate the effect of the bio-fertilizer EMI on the growth and production of Sponta Potato Solanum tuberosum. Four treatments were used as follows: cont rol, with water irrigation, spraying and irrigation, spraying. The results showed that the use of bio-fertilizer EMI improved the growth of plants, so the surface foliage, foliage index and plant height were increased significantly comparing with the control. The results also showed that the spraying and irrigation treatment was the best with a tuber average weight of 117.7 g/tube obverse (102.7, 115, 109 g/tuber), and a yield of 5864 kg/d obverse (4151, 5569, 5398 kg/d) for treatment (control, water irrigation, spraying).
This research aims to study the effect of different treatments of potato plants with a feeding organ on the growth and yield of potato crop and on the quality of tubers. The Romano variety of potato was used, and the commercial organic feeder "plan t energy 1000" was applied in four treatments. The treatments were: a control and three ways for treating the plants with the organic feeder: by roots, foliage spray, and by both in one treatment. The completely randomized design was adopted in this experiment. The experiment was implemented in the nursery farm of Tishreen University in the spring planting season of 2012. The results showed that treating potato plants with the organic feeder led in general to an increase in the growth, which was reflected in the increase in the fresh weight, total leaf area and its indication, as well as in the quality and number of tubers, total production and marketing quality. These results were clearer in the case of the joint treatment: root feeding and foliage spray together. This treatment showed significant superiority in increasing production and improving its quality.
This experiment was conducted during ١٩٩٦-١٩٩٨ to ivestigate study the effect of using different types of irrigation water on some soil properties and its cotton, corn and wheat productivity under the agroclimatic conditions of Deir Ezzor.
