The research was conducted in village Habbet in Hafa (Lattakia region) 300 meters above sea level during the period of 2016-2017 the plant material of the research is red cabbage Ruby King F1 hybrid in order to study the effect of planting date on growth and productivity of red cabbage. The study consisted of five different planting dates during the med of May, June, July, August and ,September months The completely randomized block design was used with four replications and twenty plants in replication . The study contains indicators: )leaf surface area, shape, volume, solidity and weight of cabbage heads, inner stem length, total and marketable yield, percentage of marketable yield and content of vitamin C) The results showed that planting treatment during August and September gave the superior results with significant difference in vegetative and productive indicators: leaf surface area, solidity and weight of cabbage heads, total yield )3394.8، 3654( kg/d respectively, marketable yield and percentage of marketable yield. While The planting during May, June, July was superior on content of vitamin C which was respectively (99.58, 98.68, 97.82 ( ml/100g with significant difference.

Research summary
أجريت الدراسة في قرية حبيت التابعة لمنطقة الحفة في محافظة اللاذقية على ارتفاع 300 متر عن سطح البحر خلال الموسم الزراعي 2016-2017. هدفت الدراسة إلى تحديد تأثير موعد الزراعة على نمو وإنتاج الملفوف الأحمر من نوع Ruby King F1. شملت الدراسة خمسة مواعيد زراعية مختلفة في أواسط أشهر أيار، حزيران، تموز، آب، وأيلول. تم تصميم التجربة وفق تصميم القطاعات العشوائية الكاملة بأربعة مكررات وبمعدل 20 نبات في المكرر الواحد. تضمنت القراءات: شكل الرأس، حجمه، وزنه وصلابته، طول الساق الداخلية، إنتاجية وحدة المساحة، نسبة الإنتاج التسويقي من الإنتاج الكلي، وكمية فيتامين C. أظهرت النتائج تفوق الزراعة في شهري آب وأيلول على باقي المعاملات بفروق معنوية من حيث مؤشرات النمو الخضرية والإنتاجية. بينما تفوقت مواعيد الزراعة في أيار، حزيران، وتموز بفروق معنوية في كمية فيتامين C. خلصت الدراسة إلى أن الزراعة في شهري آب وأيلول هي الأفضل من حيث الإنتاجية الكلية والتسويقية.
Critical review
تعتبر الدراسة ذات أهمية علمية وتطبيقية كبيرة، خاصةً أن زراعة الملفوف الأحمر في سوريا حديثة نسبياً. ومع ذلك، يمكن تحسين الدراسة من خلال توسيع نطاق البحث ليشمل مناطق بيئية مختلفة وأصناف متعددة من الملفوف الأحمر. كما يمكن أن تكون هناك حاجة لمزيد من الدراسات لتحديد تأثير العوامل البيئية الأخرى مثل نوع التربة ومستوى الرطوبة على نمو وإنتاجية الملفوف الأحمر. بالإضافة إلى ذلك، يمكن أن تكون هناك حاجة لدراسة تأثير مواعيد الزراعة على جودة المنتج النهائي من حيث الطعم والقيمة الغذائية.

The research aimed to compare three hybrids of broccoli (Condi, Kuba and NS50), grown under Damascus environment, for their morphological, yield and quality characters. The results showed that NS50 had the largest number (p<0.05) of leaves and ste m length, Kuba had the greatest (p<0.05) main head and the stalk length, In addition, higher TSS and vitamin C content while NS50 hybrid showed the best firmness, the highest chlorophyll and carotene contents and higher fresh weight of main head than Condi. The lateral heads number and their fresh weight were higher in Condi than the other hybrids.
The experiment was performed at Agricultural Research Center in Jousiyet Al-Kharab in Al-Qsair district, Homs governorate during the 2010-2011 season to investigate the effect of planting depth and organic acids on saffron growth and productivity. Four treatments including amino acids, amino Humic, mixture of them in addition to the control were applied. Each treatment was comprised of three planting depths (10, 15 and 20 cm). Results showed that by increasing planting depth up to 20 cm a significant reduction had resulted in the percentage of rooted plants and number of shoots while there were no significant differences between the two depths 10 vs. 15 cm. The number of leaves and their length were not affected significantly with the increasing of planting depths. The number of flower, wet and dry weights of the stigmas were increased significantly with the increase of planting depth from 10 to 15 cm. The application of the humic acids had significant superiority overall the other applications in rooted plant percentage, number of shoots, number of flowers and the dry and wet weights of the stigmas, while the application of the mixture came in the second rank in number of flowers and the dry and wet weights of the stigmas. However, no significant differences were occurred between the control and application of amino acids. The highest percentage of rooted plants was observed in applying humic acids in all depths and the percentage of rooted plants reached 100%. The highest number of flowers, highest stigmas wet and dry weights were observed with the interaction between applying humic acids at 15 cm depth. The highest number of shoots and number of leaves appeared with the interaction between 20 cm depth and humic acids treatment, the longist leaves were appeared with the interaction between amino acids and 15 cm depth.
This study was carried out during the growing season of 2015 to study effect od three planting date (1 Feb., 15 Feb. and 1 March) and four levels of nitrogen fertilization (0, 40, 60 and 80 kg/Ha) with interactive effect between them on some yield components of cumin.
We evaluated some of the qualities of productivity for lentil variety ( Lens esculanta ) Idlib2 in the province of Hama, which lies within the third zone in the two seasons 2013- 2014. manner random sectors dissident once and three replications fo r each worker where she planting dates widget Home and operated plant density widget dissident once in order to determine the date and density suitable to reach the best production of lentils in a peaceful area. Agriculture led on the first date (December 15) and in the plant a minimum density (200 seeds / m2) increased to varying significantly different in the length of the century / mm and the total number of horns on a per plant and the number of seeds per plant and seed weight on a per g / plant and seed weight per hectare And it gave the plant Top-density (300 seeds / m 2) a significant increase in the weight of centuries per g / plant and the number of pods on the plant and the weight of Aalakec per hectare and biological weight per hectare.
