Research summary
أجريت دراسة لتحديد تأثير الكثافة النباتية على إنتاجية ثلاثة طرز وراثية من الذرة الصغراء (غوطة 82، باسل1، وباسل2) في مزرعة أبي جرش بجامعة دمشق. استخدمت كثافتين نباتيتين: 35.71 ألف نبات/هكتار و71.43 ألف نبات/هكتار. تم تقييم عدة صفات شكلية وإنتاجية مثل ارتفاع النبات، طول العرنوس، عدد الصفوف والحبوب في العرنوس، وزن الحبوب في العرنوس، وزن الألف حبة، الغلة الحبية، ونسبة القولحة. أظهرت النتائج تفوق صنف غوطة 82 في ارتفاع النبات ونسبة القولحة، بينما أعطى أقل وزن للحبوب في العرنوس. لم يكن للكثافة النباتية تأثير معنوي على إنتاجية الطرز الوراثية المدروسة. كما أظهرت الدراسة وجود علاقة ارتباط موجبة بين الغلة الحبية وكل من ارتفاع النبات، وزن الحبوب، ووزن الألف حبة.
Critical review
دراسة نقدية: تعتبر الدراسة شاملة ومفصلة في تحليل تأثير الكثافة النباتية على إنتاجية الذرة الصغراء، ولكن يمكن تحسينها من خلال تضمين المزيد من التفاصيل حول الظروف البيئية والتربة التي قد تؤثر على النتائج. كما أن الدراسة اعتمدت على كثافتين نباتيتين فقط، مما قد يحد من إمكانية تعميم النتائج على نطاق أوسع. يمكن أن تكون إضافة كثافات نباتية أخرى مفيدة لفهم أعمق لتأثير الكثافة على الإنتاجية. بالإضافة إلى ذلك، يمكن تحسين الدراسة من خلال تضمين تحليل اقتصادي لتكلفة وفوائد استخدام كثافات نباتية مختلفة.

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.
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.
The study was carried out at Abo Jarash farm, Faculty of Agriculture, Damascus University, during the growing season of 2012, where the maize cultivar "Gouta 1" was grown in three agricultural spacings (20, 30 and 40 cm between plants in the same row), with a fixed space (70 cm) between rows, according to the randomized complete block design and three replicates per treatment, in order to study the effect of the studied agricultural spacing on the following characters: plant height, length and weight of ear, number of kernel rows per ear, number and weight of kernels per ear, net percentage, hundred kernels weight, the kernel yield, the dry yield and the oil and protein contents in the kernels. Results showed a significant decrease in plant height from 155.31 to 130.10 cm, while a significant increase was observed in number of kernels per ear (from 310.05 to 373.82 kernels), in weight of kernels per ear (from 41.20 to 65.17 g) and in net percentage (from 61.61 to 91.51 %), respectively with the increase of agricultural spacing from 20 to 40 cm. However, the increase in these characters didn’t substitute the small number of plants in the vast spacing compared with the narrow spacing, which is reflected in kernel yield per unit of area that amounted to 3.19 and 2.04 tons/ha, respectively.
This study was conducted at the farm of Faculty of Agricultural –Kharabo as an intensive crop during 201 and 2012 growing seasons. Using the Randomized Complete Block Design (RCBD) with two replications to study some genetic indices for grain yiel d and its components, of 79 families of the Sh group of maize improved by Full-sib selection. The results indicated that the broad sense heritability ranged from high to moderate for some yield components (number of kernels per row, number of rows per ear, ear length, ear diameter, the weight of whole ear, whole kernel weight and grain yield and it was 49.6, 52.9, 46.3 79.7, 56.74, 51 and 85.2%) respectively. Additive gene action appeared to be controlling number of kernel per row, number of rows per ear, ear length, ear diameter،,grain yiel, the weight of whole ea, kernel weight indicating less selection cycles are required to improve yield depending on its components.
A half diallel set of crosses among six inbred lines of maize were evaluated at the Maize Research Department (G.C.S.A.R.) in Damascus Governorate during 2010 and 2011 growing seasons to estimate heterosis and combining ability components for the n umber of rows per ear, number of kernels per ear, ear length (cm), ear diameter(cm), 100-kernel weight (g), and grain yield (ton /hec). The inbred lines, crosses, general combining ability (GCA) and specific combining ability (SCA) mean squares were highly significant for all the studied traits, showing the existence of a genetic variance among lines. The ratios of GCA to SCA detected for the studied traits showed the dominance of an additive gene action for all the studied traits except for 100-kernel weight and grain yield which showed the predominance of a non-additive gene action. The heterosis percentage for the studied traits was significant based on mid and better parents. The GCA effects showed that the lines CML.317, CML.371, CML.373 and CML.367 were good general combiners for grain yield, while the SCA effects showed that seven hybrids were the best F1 cross combinations such as (CML.317×CML.371) for grain yield.
