نفذ البحث في مشتل جامعة تشرين في الموسم الزراعي الربيعي لعام 2015، حيث تمٌ دراسة تأثير المخصب الحيوي EM1 في نمو و انتاج البطاطا (الصنف سبونتا)، تضمن البحث أربع معاملات: 1 – شاهد، 2 – تغذية جذرية بالمخصب الحيوي EM1، 3 –تغذية جذرية +رش المجموع الخضري، 4- رش المجموع الخضري بالمخصب الحيوي EM1. أظهرت النتائج أن استخدام المخصب الحيوي EM1 أدى إلى تحسين نمو النباتات من خلال زيادة مساحة و دليل المسطح الورقي و متوسط ارتفاع النبات و بفروق معنوية عن الشاهد، كما بينت النتائج أيضاً تفوق معاملة الرش الورقي مع التغذية الجذرية بفروق معنوية في متوسط وزن الدرنة 117.7غ/درنة مقابل (102.7 ، 115، 109 غ / درنة)، و في الإنتاجية إذ بلغت 5864 كغ/دنم مقابل (4151، 5569، 5398 كغ / دنم ) للمعاملات (شاهد، تغذية جذرية، رش المجموع الخضري) بالترتيب.
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).

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.
