An experiment was conducted on maize crop (Zea mays L.) in plastic pots in two different soils (Qurna soil, which is poor organic matter and the other soil from Maysan marshes, which is rich in organic matter), to study the effect of selenium, sulfur and phosphate and their interaction on dry weight of shoot of maize crop. Selenium was added at four levels (0, 10, 20 and 40 g Se ha), sulfur at three levels (0, 30 and 60 kg S ha), and phosphorus at three levels (0, 60 and 120 kg P ha).

Research summary
تناولت الدراسة تأثير التسميد بالسيلنيوم والكبريت والفوسفور على الوزن الجاف للمجموع الخضري لمحصول الذرة الصغراء المزروعة في تربتين مختلفتين: تربة القرنة الفقيرة بالمادة العضوية وتربة أهوار ميسان الغنية بالمادة العضوية. أضيف السيلنيوم بأربعة مستويات (0، 10، 20، 40 غ/هكتار)، والكبريت بثلاثة مستويات (0، 30، 60 كغ/هكتار)، والفوسفور بثلاثة مستويات (0، 60، 120 كغ/هكتار). أظهرت النتائج زيادة معنوية في الوزن الجاف للمجموع الخضري مع زيادة مستويات السيلنيوم والفوسفور في كلا التربتين. بينما كانت الزيادة في الوزن الجاف مع زيادة الكبريت معنوية فقط في تربة القرنة. لم يكن للتداخل الثنائي بين السيلنيوم والكبريت أو السيلنيوم والفوسفور أو التداخل الثلاثي بين السيلنيوم والكبريت والفوسفور تأثير معنوي على الوزن الجاف للمجموع الخضري. كانت أعلى القيم للوزن الجاف عند المعاملة Se S (16.20 و18.00 غ/5 نباتات) والمعاملة Se P (16.27 و18.48 غ/5 نباتات) والمعاملة Se S P (16.90 و18.70 غ/5 نباتات) في تربتي القرنة والأهوار على التوالي.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لفهم تأثير العناصر الغذائية المختلفة على نمو محصول الذرة الصغراء، خاصة في ظل اختلاف نوعية التربة. ومع ذلك، كان من الممكن توسيع نطاق الدراسة لتشمل المزيد من الترب المختلفة لتحسين تعميم النتائج. كما أن الدراسة لم تتناول تأثير التسميد على الجوانب الأخرى للنبات مثل الإنتاجية الكلية وجودة الحبوب، مما قد يكون له أهمية كبيرة للمزارعين. بالإضافة إلى ذلك، كان من الممكن استخدام تقنيات تحليلية أكثر تطوراً لتحديد تأثير التداخلات بين العناصر الغذائية بشكل أدق.

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.
A pot exrpriment was conducted in a greenhouse in Tishreen University. The experiment included three soils differ in their chemical properties: 1) heavy clay red soil rich in iron oxides; 2) a silty loam basiltic soil; 3) a heavet clay red soil ric h in total calcium carbonate (34.8 %). Treatments include application of different levels of triple super phosphate (TSP, 46 % P2O5) ranged from 0, 20, 40, 60, 80, 100, 150, to 200 mg P/kg soil. Pots were sowned with maize (2 plants/pot) and grown for 48 days. At harvest, plant were hatvested before flowering by cutting shoots and extracting roots which were oven dried and weight were recorded prior to digestion and P determination in shoot and root tissues. Samples of rhizosphere soils from each pot replicate were taken for P fractionation and determination. The response of maize to P application differs at period test according to soil type. The increase in growth was linear with increasing P level of application in theheavy red and calcareous red soils, while was polynomial in basilitic soil. The speed of growth increase in response to P application was influenced by native available P in the soil prior to application. The application of P led to linear increase in resin-P and MRP fraction in the bicarbonate extract, but not the Po fraction of the bicarbonate extract. The quantities of fixed applied P varied according to level of P application, the ratio of P uptake by maize plants, and chemical properties of the soil type. The proportion of applied P that was fixed increased linerarly with increasing level of P application. It constitutes 41.7,68.5 and66% at level of P application (20 mg/kg soil), and decreasing to30.2, 41.9 and 59.1% at level of P application (200 mg/kg soil) for red, basiltic, and calcerous red soils, respectively.
This study was carried out in the farm of the Faculty of Agriculture University of Damascus during the growing season 2014, to study the productivity of the maize cultivar ("Gouta 82) and the hybrids (Basel 1 and Basel 2) under the influence of tw o plant densities 17.53 thousand plant. ha-1 (70x20cm) and 53.11 thousand plant. ha-1 (70x40cm).
The research was conducted at the Maize Researches Department, General Commission for Scientific Agriculture Researches (G.C.S.A.R.) Damascus, Syria during the summer growing seasons of 2010, 2011 and 2012. Treatments were arranged in a Randomized Complete Blocks Design with three replications. The research aimed to evaluate genetic parameters for some traits like days to 50% silking, plant and ear height, ear length, ear diameter, number of rows per ear, number of kernels per row, 100 kernel weight and grain yield per plant using generations means analysis of two maize hybrids (IL.292-06 × IL.565-06, IL.459-06 × IL.362-06) to detect epistasis and estimates of mean effect [m], additive [d], dominance [h], additive × additive [i], additive × dominance [j] and dominance × dominance [l] parameters. Results showed that the additive - dominance model was adequate to demonstrate the genetic variation and its importance in the inheritance of most studied traits. Nonallelic gene interaction was operating in the control of genetic variation in most studied traits. The signs of [h] and [l] were opposite in most studied traits for the two crosses. Also, the inheritance of all studied traits was controlled by additive and non-additive genetic effects, but dominance gene effects play the major role in controlling the genetic variation of the most studied traits, suggesting that the improvement of those characters need intensive selection through later generations. The phenotypic variations were greater than genotypic variations for all studied traits in the two crosses, indicating greater influence of environment in the expression of these traits. Highly significant heterosis relative to mid and better parents, respectively was found for all characters, and this accompanied with inbreeding depression for all traits. Narrow sense heritability and genetic advance were low in most of the traits due to the dominance of non-additive gene action in controlling the genetic variation of the most studied traits and this predict low to medium values of genetic advance through selection process.
This study was carried out during 2010-2011 growing seasons at the Maize Researches Department (G.C.S.A.R.) Damascus. To estimate heterosis for number of rows per ear, ear length, ear diameter, 100- kernel weight, and grain yield.
