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: control, 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).

Research summary
تناولت الدراسة تأثير المخصب الحيوي EM1 على نمو وإنتاجية البطاطا (الصنف سبونتا) في العروة الربيعية تحت ظروف المنطقة الساحلية السورية. تم تنفيذ البحث في مشتل جامعة تشرين في الموسم الزراعي الربيعي لعام 2015، وشملت الدراسة أربع معاملات: شاهد، تغذية جذرية بالمخصب الحيوي، تغذية جذرية + رش المجموع الخضري، ورش المجموع الخضري بالمخصب الحيوي. أظهرت النتائج أن استخدام المخصب الحيوي EM1 أدى إلى تحسين نمو النباتات وزيادة مساحة ودليل المسطح الورقي وارتفاع النبات بفروق معنوية عن الشاهد. كما تفوقت معاملة الرش الورقي مع التغذية الجذرية بفروق معنوية في متوسط وزن الدرنة والإنتاجية، حيث بلغت الإنتاجية 5864 كغ/دنم مقارنة بالشاهد والمعاملات الأخرى. توصي الدراسة باستخدام المخصب الحيوي EM1 لتحسين إنتاجية البطاطا من خلال التغذية الجذرية والرش الورقي.
Critical review
دراسة نقدية: على الرغم من أن الدراسة قدمت نتائج إيجابية حول تأثير المخصب الحيوي EM1 على نمو وإنتاجية البطاطا، إلا أنه يمكن توجيه بعض الملاحظات النقدية. أولاً، لم تتناول الدراسة تأثير المخصب الحيوي على جودة الدرنات من حيث المحتوى الغذائي أو الطعم. ثانياً، لم يتم التطرق إلى تكلفة استخدام المخصب الحيوي مقارنة بالأسمدة التقليدية، وهو عامل مهم للمزارعين. ثالثاً، كان من الأفضل إجراء الدراسة على مدى عدة مواسم زراعية للتحقق من استدامة النتائج. وأخيراً، لم يتم مناقشة التأثير البيئي لاستخدام المخصب الحيوي بشكل كافٍ، وهو جانب مهم في الزراعة المستدامة.

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.
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
Marfona cultivar were chemical mutagen using 20, 30 and 40 mM of Ethyl Methane Sulphonate (EMS) for 2, 3, 4 hrs in 2013. was conducted to improve potato (Solanum tuberosum L.) tolerance to salinity. Plants Marfona mutagen from M5 and unmutagen were cultured with Spunta and Falouka Cvs in 2015. Plants were later subjected to another selection pressure, by irrigating them using water containing Nacl between 0-200 mM The results showed that the gradual increase in Nacl concentrations caused a significant gradual decreases in most vegetative, yield and its component characteristics. Mutant plants varied with unmutant for Marfona, Spunta and Falouka in plant height varied from 68 to 41 cm and number leaves varied from 21 to 12 leaf. and stem diameter varied from 1.349 to 0.370 cm and leaf area varied from 235 to 84 cm2. However, produced tubers number varied from 9.3 to 2.8 and weight them from 740 to 155 grams and tuber weight from 75.2 to 24.6 grams. The results also showed variations in the extent of tolerance between studied treatments to salinity stress where 4T3P2 treatment was the most tolerant.
Experiments were conducted to study effect of radiation and salt levels on plant regeneration from callus for two cultivars of potato i.e. Riviera and Burren, under in vitro condition. Results showed that the efficiency of radiation in induced reg eneration from callus in Riviera cultivar at salt level of (10 dS m-1) and Burren cultivar at salt levels (8, 12 dS m-1). For the purpose of making sure inheritance of salinity tolerant, mutant clones (plants induced from salt tolerant calli, which planted at salt levels of 8, 10, 12 dS m-1 and plants induced from non salt tolerant calli, which planted at salt level of 6 dS m-1) and their parental cultivars (Riviera and Burren) by exposing to salt stress conditions and comparing them with control (6 dS m-1). Results revealed that the lowest percentage of reduction in plant height, number of nods per plant and tuberization were observed in salt tolerant mutants. Plant height and number of nodes/plant can be considered as selective morphological markers for in vitro salt tolerance .
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.
