هدف هذا البحث إلى تحديد كل من وسط و موعد الزراعة الأفضل لإنتاج اللفائف الخضراء المكونة من خلطة الأعشاب Lolium perenne) Festuca Arundinacea, Festuca rubra, Poa partensis, ) و بأقل التكاليف الممكنة, حيث تم اختبار سبعة أوساط مختلفة و في موعدين زراعيين مختلفين (15 أيلول و 1 نيسان). أظهرت النتائج أن وسط الزراعة المكون من التورب أو من بقايا كمبوست الفطر الزراعي أعطى أفضل نسبة إنبات (78 – 84%) و لموعدي الزراعة. كما أعطى الوسطان السابقان لفائف جاهزة بفترة زمنية أقل من الأوساط الأخرى (78 – 102 يوماً), بالإضافة إلى أفضل نوعية من اللفائف الخضراء من حيث خفة الوزن(41,96 – 53,89كغ/م2) , معدل التغطية (93 – 98%) و اللون. حقق الوسط المكون من بقايا كمبوست الفطر الزراعي ربحاً اقتصادياً أعلى مقارنةً بالأوساط الأخرى. حيث كان معامل الربحية (194,4 %).
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%).

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.
The objective of the research is to identify the optimal date of
planting when mutual intercropping (line: line) is used in planting
beans Phaseolus vulgaris L. and sweet corn Zea mays rugose L.
