The aim of this research is to determine the best date and culture medium for the production of big rolls consisting of seed mixture (Lolium perenne, Festuca Arundinacea, Festuca rubra, Poa partensis) with the lowest costs. Seven different mediums were experimented in two different culture dates (15 September and 1 April). The results showed that the mediums consisting of turf or spent mushrooms compost gave the best germination rate (78-84%) in the two culture dates. They also gave ready big rolls in a period of time less than in the other mediums (78-102 days). The mediums also gave the best quality of big rolls in terms of light weight (41.96- 53.89 kg/m2), coverage rate (93-98%), and color. The medium that consisted of spent mushroom compost achieved an economic increase higher than that in the other mediums, where the coefficient of profitability in the former was (194.4%).

Research summary
هدفت الدراسة إلى تحديد أفضل وسط وموعد للزراعة لإنتاج لفائف خضراء من خلطة الأعشاب (Poa partensis, Festuca Arundinacea, Festuca rubra, Lolium perenne) بأقل التكاليف. تم اختبار سبعة أوساط زراعية في موعدين مختلفين (15 أيلول و1 نيسان). أظهرت النتائج أن وسط الزراعة المكون من التورب أو بقايا كمبوست الفطر الزراعي أعطى أفضل نسبة إنبات (78-84%) وأفضل نوعية لفائف من حيث الوزن (41.96-53.89 كغ/م²) ومعدل التغطية (93-98%) واللون. كما حقق الوسط المكون من بقايا كمبوست الفطر الزراعي أعلى ربحية اقتصادية (194.4%).
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو تحسين إنتاج المسطحات الخضراء بطرق اقتصادية وفعالة. ومع ذلك، يمكن توجيه بعض الملاحظات النقدية لتحسين البحث في المستقبل. أولاً، يمكن توسيع نطاق الدراسة ليشمل أنواعاً أخرى من الأوساط الزراعية المتاحة محلياً والتي قد تكون أكثر اقتصادية. ثانياً، يمكن إجراء تجارب إضافية لتحديد تأثير العوامل البيئية المختلفة مثل درجات الحرارة والرطوبة على نتائج الزراعة. أخيراً، يمكن تحسين منهجية البحث من خلال زيادة عدد المكررات لكل معاملة لضمان دقة النتائج وتقليل التباين.
Questions related to the research

    الأوساط الزراعية المكونة من التورب وبقايا كمبوست الفطر الزراعي أعطت أفضل نسبة إنبات (78-84%).

  2. ما هي الفترة الزمنية اللازمة للحصول على لفائف جاهزة باستخدام أفضل الأوساط الزراعية؟

    الفترة الزمنية اللازمة للحصول على لفائف جاهزة باستخدام الأوساط المكونة من التورب أو بقايا كمبوست الفطر الزراعي كانت بين 78 و102 يوماً.

  3. ما هو معامل الربحية للأوساط الزراعية المختلفة؟

    حقق الوسط المكون من بقايا كمبوست الفطر الزراعي أعلى معامل ربحية بنسبة 194.4%.

  4. ما هي العوامل التي أثرت على اختلاف نسبة الإنبات بين الأوساط الزراعية؟

    اختلاف نسبة الإنبات بين الأوساط الزراعية يعود إلى خصائص الوسط من حيث النفاذية والقدرة على الاحتفاظ بالرطوبة، بالإضافة إلى تأثير الأوساط العضوية في رفع درجة الحرارة في وسط الإنبات.

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.
The research was Carried out in Jisr area in the province of Idlib during the growing season 2013 - 2014 to study the effect of planting dates in autumn sowing 28/9/2013 = (1), 8/10/2013 = (2), 18/10/2013 = (3) and spring sowing 18/3/2014 = (1), 28 /3/2014 = (2), 8/4/2014 = (3) on yield and growth parameters. The results showed that the autumn sowing has a significant increase in growth parameters compared to spring sowing: adapting coefficient (76.67-82.28%), Plant hight (67.15 - 56.3 cm), number of branches/plant (11.63 - 6.84), number of head/Plant (21.39 - 17.76), oil content (23.19 - 20.68)%, yield petals (96.12 - 60.57) kg/ha, seed yield (1331.82 - 768.31) kg/ha, oil yields (315.15 - 158.99) kg/ha to autumn and spring, respectively. While maturity date of autumn plants was delayed compared to spring (245.33 - 145.33) Day. When sowing was of autumn, growth parameters of third soing date were a significantly higher compared to both the second and first sowing: number of branches / plant, number of heads / plant, number of seeds / head, oil ratio (%), oil yield (kg/ha), yields seeds ( kg/ha), petals yield (kg/ha). Wheras the first sowing date has delayed maturity date compared of both the second and third sowing dates. When sowing was in spring, growth parameters of the first sowing dates were a significantly higher compared to both the second and third except for days to maturity.
This study was conducted at the biotechnology laboratory of AnimalWealth Research Administration, General Commission for Agricultural Research in order to compare the effect of different media on In vitro maturation (oocytes matured at 39 C° under 5% CO2 for 24 h), fertilization، and culture (7 days postfertilization) in humidified atmosphere 95% on bovine embryo production.
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.
