The research was carried out in the fields of Akar plain in Tartous province during two seasons (2013, 2014) to study the effect the three multiplication methods (Slips as control, Seedling, Cut-seed tuber) on growth and yield of two locally spread sweet potato varieties. The experimental design was a randomized complete block with three replications. Data were analyzed using the statistical program GenStat 12.

Research summary
تُعنى هذه الدراسة بتقييم تأثير ثلاث طرائق إكثار (العقل، الشتول، الجذور المقطعة) على نمو وإنتاجية صنفين من البطاطا الحلوة في سهل عكار بمحافظة طرطوس خلال موسمي 2013 و2014. أظهرت النتائج أن طريقة الإكثار بالجذور المقطعة كانت الأكثر فعالية في زيادة عدد الأفرع والأوراق في كلا الصنفين، بينما كانت طريقة الشتول الأفضل في زيادة طول الأفرع وعدد الجذور في الصنف الثاني. من ناحية أخرى، تفوقت طريقة الإكثار بالعقل من حيث وزن الجذور الإنتاجية والإنتاجية الكلية لكل دونم في كلا الصنفين. بناءً على هذه النتائج، توصي الدراسة باستخدام طريقة الإكثار بالعقل للحصول على إنتاجية عالية، مع الحاجة لمزيد من الدراسات حول طرائق الإكثار بالشتول والجذور المقطعة في مواعيد زراعة مختلفة.
Critical review
دراسة نقدية: على الرغم من أن الدراسة قدمت نتائج مفيدة حول تأثير طرائق الإكثار المختلفة على نمو وإنتاجية البطاطا الحلوة، إلا أنها لم تتناول بعض الجوانب الهامة مثل التأثيرات البيئية المحتملة على النتائج. كما أن الدراسة اقتصرت على موسمين فقط، مما قد لا يعطي صورة شاملة عن تأثيرات طرائق الإكثار على المدى الطويل. بالإضافة إلى ذلك، لم يتم التطرق إلى التكلفة الاقتصادية لكل طريقة إكثار، مما يمكن أن يكون عاملاً مهماً للمزارعين عند اختيار الطريقة المثلى. يُفضل أن تشمل الدراسات المستقبلية هذه الجوانب للحصول على صورة أكثر شمولية.

    طريقة الإكثار بالعقل تفوقت من حيث وزن الجذور الإنتاجية والإنتاجية الكلية لكل دونم في كلا الصنفين.

  4. ما هي التوصية الرئيسية التي قدمتها الدراسة بناءً على النتائج؟

    توصي الدراسة باستخدام طريقة الإكثار بالعقل للحصول على إنتاجية عالية، مع الحاجة لمزيد من الدراسات حول طرائق الإكثار بالشتول والجذور المقطعة في مواعيد زراعة مختلفة.

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 .
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.
A field experiment was conducted for two consecutive seasons 2006 – 2007 and 2007 – 2008 to investigate the effect of removing early developed buds on growth, yield and some lint proprieties. Treatments involved in the experiment included three le vels of bud removal (0%, 50%, and 100%) at three times (one, two and three weeks after budding). The treatments were arranged in FRCBD, with three replications. Growth parameters (plant height, number of nodes/plant, number of leaves/plant, and number of branches/plant) cotton seed yield, lint yield and lint properties were investigated. The results revealed that bud removal significantly increased plant height, number of nodes, cotton seed yield and lint yield, uniformity (UR) and lint strength (HVI). Also the results showed that, time of bud removal significantly affected growth parameters, cotton seed yield and lint cotton. The results indicated that, varieties and time of bud removal interaction had a significant affect on growth parameters. While, percentage of bud removal and time of bud removal interaction had a significant effect only on cotton seed yield and strength of lint. The results showed that, there were significant difference between cultivars in plant height and number of branches per plant, with cultivar Barakat – 90 the best.
Field experiment was carried out at Research Station of the Faculty of Agriculture, Muthanna University, Iraq, during 2014/2015 season, to study the effect of adding NPK, biofertilizers Bacillus Subtilis and Glomus Mosseae on the growth and yield of maize (Zea may L.). The treatments were i.e control (zero: no vaccine), biofertilizers Bacillus subtilis treatments, Glomus mosseae, both biofertilizers (F0, F1, F2 and F3), respectively, Three levels of NPK liquid fertilizer i.e. 0, 5000, 7500 mg )C0, C1, and C2 respectively). The experiment design was RCBD with three replications arranged according to split plot.
This research was conducated on Ceratonia siliqua L. in vitro to study the effect of some growth regulators in both multiplication and rooting stage. And determine the best concentrations wich lead the highest rate of multiplication (interms of number of shoots and length), and the best rooting (interms of percentage of rooting, number of roots and length).
