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+ biofertilizer 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.

Research summary
تتناول هذه الدراسة تأثير الأسمدة العضوية والحيوية (Azotobacter والبكتيريا المذيبة للفوسفات) على إنتاج البطاطس وبعض خصائص التربة في طرطوس. تضمنت التجربة أربع معاملات (تربة + سماد عضوي، تربة + سماد حيوي، تربة + سماد عضوي + سماد حيوي) مع تكرار كل معاملة أربع مرات لموسمي 2004 و2005. تم قياس إجمالي النيتروجين، الفوسفور المتاح، البوتاسيوم المتاح، والمادة العضوية في التربة. أظهرت النتائج زيادات كبيرة في معظم المعاملات الملقحة بالأسمدة الحيوية والعضوية مقارنة بالتحكم. كانت المعاملة (تربة + سماد عضوي + سماد حيوي) الأفضل وأظهرت زيادات كبيرة في إنتاج البطاطس مقارنة بالمعاملات الأخرى خاصة في الموسم الثاني. كان الموسم الثاني أفضل من حيث زيادة الإنتاج في جميع المعاملات مقارنة بالموسم الأول.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال الزراعة المستدامة حيث تسلط الضوء على فوائد استخدام الأسمدة الحيوية والعضوية في تحسين إنتاجية المحاصيل وخصائص التربة. ومع ذلك، يمكن انتقادها من حيث عدم تناولها لتأثيرات طويلة الأمد لهذه الأسمدة على التربة والبيئة. كما أن الدراسة لم تتناول الجوانب الاقتصادية لاستخدام هذه الأسمدة مقارنة بالأسمدة الكيميائية التقليدية. كان من الممكن أيضًا تحسين الدراسة من خلال تضمين مجموعة أوسع من المحاصيل والبيئات الزراعية المختلفة للتحقق من تعميم النتائج.

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.
The experiment was carried out in Tartous Governorate in the Qubeiba region in the two agricultural seasons 2011 and 2012 to study the effect of different types of ploughs, the depth of plowing, and the timing of adding nitrogen fertilizer on some ph ysical and chemical properties of the soil and some growth indicators of peanuts and its productivity. Three types of plows were used: MP ), disc plow ( DP ) and backhoe plow ( CP ) .
This study was carried out in the nursery gardens of Tishreen University in the early spring period in 2014, to study the effect of different levels of dry organic manure in the growth and productivity of potato plants (class Spunta), in randomized complete design, study included six treatments: control ( cow organic manure amount of 4 kg/m2) and five treatment with five levels of dry organic manure (100-150-200-250-300 g/m2) .The results showed an increase in stem height, number of stem, foliage area, production and percent of standard tubers by adding dry organic manure at level of 250 g/m2 while Treatment with 300g/m2 contributed an increase of folige area, height of plant and stem number while causing reduced plant production,tuber average weight and production of standard tubers.The result showed also no significant differences between the control and the treatment of 250 g/m2dry organic manure in each of the folige area, production and standard tubers
The effect of organic and biological fertilizers on the yield and quality of Shami anise plant grown in Abi Jerash farm, Faculty of Agriculture in the conditions of Damascus city, and testing the anti-fungal effect of Shami anise oil and its extracts on Candida albicans.
This study was conducted in Abu-Jarash farm at the Faculty of Agriculture, Damascus University during the main season 2013 to evaluate the effect of soil solarization and organic fertilization treatments on the productivity of some maize genotypes (Basel 1, Basel 2, Ghouta 1, Ghouta 82 and Local White). The experiment was laid out according to split-split plot design with three replications. The statistical analysis results clearly indicated to the existence of variability in the response of studied maize genotypes to soil solarization and organic fertilization treatments. The genotype Ghouta 82 surpassed in the traits of plant height, leaf area index, 100-kernel weight and grain yield (150.25 cm, 2.84, 28.10 g and 7.99 ton.ha-1) respectively, as compared to other studied genotypes and was closely followed by the genotype Basel 2 which recorded the highest number of rows per ear (13.83 row/ear). Soil solarization for 45 days before sowing and applying organic manures at the rate of 20 ton.ha-1 encouraged the traits of plant height, leaf area index, number of rows and grains per ear, 100-kernel weight which was reflected on grain yield. Therefore we can grow variety Ghouta 82 or hybrid Basel 2 to get higher yield of maize.
