إن اختيار أسلوب حراثة التربة المناسب يعد خطوة أساسية هامة في تحضير التربة الزراعية، لذلك قمنا بتنفيذ بحث في المنطقة الغربية من محافظة حمص، باستخدام أساليب الحراثة (القلابة المطرحية، القلابة القرصية، الشاقة غير القلابة، السطحية)، لتجهيز المرقد المناسب لزراعة بذور اليانسون Pimpinella anisum و نموها.
The type of tillage methods is considered to be as an important factor for seed bed preparation, consequently, this will be reflected in the quantity and quality of production, different types of tillage methods were used such as turning plough, standard disk plough etc, for Anise Pimpinella anisum seed bed preparation, the experiment was conducted in the western area of Homs province.

The type of tillage methods is considered to be as an important
factor for seed bed preparation, consequently, this will be reflected
in the quantity and quality of production, in comparison to control
(minimum tillage) different types of tillage
methods were used such
as turning plough, standard disk plough etc, for Anise Pimpinella
anisum seed bed preparation, the experiment was conducted in the
western area of Homs province.
The experimental was carried out to estimation the
influence of competitive irrigation, organic, and chemical
fertilization treatments as well as the interaction of them on
coriander plant (Coriandrum sativum L.) by FRCBD in three
replications.
A field experiment was conducted during the two consecutive growing seasons
(2010/2011 and 2011/2012) at Ezra’ Research Station/Deraa/Syria in order to evaluate the
role of some agricultural practices in improving the performance of four wheat vari
eties
(Acsad1105, Acsad1229, Acsad885 and Acsad901) under rainfed conditions. The experiment
was laid according to factorial randomized complete block-split design with three
replications. The mean average of early vigor, flag leaf area, peduncle length and leaf area
index was significantly higher during the first growing season for the wheat variety
(Acsad901) at the first planting date with a nitrogen amount of (150 kgN. Hectar1), and
when nitrogen fertilizers were added twice (1.6-2.5, 53.4cm2, 16.3cm, 1.20 respectively).
The mean average of the same studied aspects, however, was significantly lower during the
second growing season in the case of the variety Acsad855 with regards to the early vigor,
as well as in the case of the variety Acsad1129 in the case of the leaf area Flag at a late
planting date, and without nitrogen fertilizers (3.6 4.5, 3.3 cm, 0.18, 16.6 cm2
respectively). The mean average of the grain yield was significantly higher during the first
growing season for two wheat varieties (Acsad901, Acsad1229) at the first planting date,
nitrogen rate 200 kgN. Ha-1, and when nitrogen fertilizers were added twice (660.4, 631.1
g.m-2 respectively), while it was significantly lower during the second growing season for
the variety Acsad1105, at a late planting date, and without nitrogen fertilizers (127 g.m-2).
Optimizing some important cultural practices helps increasing wheat grain yield by
improving morpho-physiological traits related to yield particularly the size of source
photo synthise (Leaf Area Index, Flag leaf area). The response of astivum wheat variety
was better compared to durum wheat. This shows the importance of improving crop
mangment factors in order to reach the maximum potential yield.
The research was carried out at Agricultural Scientific Research Center of Hama
in tow season 2010/2011. Aiming to evaluate the effect of nitrogen fertilization and
planting date on some Productive and Technological characters of sugar beet Mono
g
erm(Simper cultivar) and Multi germ (HM10 cultivar). Results showed an effect of
fertilization on productive and technological characters of sugar beet. Increasing the rate of
nitrogen fertilizer to 250kg N.ha¹ caused a significant increase in root yield and actual
sugar yield (12.88 , 12.15 ton . ha¹) respectively, but it badly affected the sugar content in
the roots, juice polarity and juice purity (14.68, 15.95, 80.45%) respectively. Mono germ
Simper was found significantly superior compared to Multi germ HM10 in root yield, Brix,
root sugar content and juice polarity. Results showed that planting date 1/11 was found
significantly superior compared to dates 1/10, 15/10 for root yield, Brix, juice purity,
actual sugar yield. In conclusion, Simper (Mono germ) was suitable in planting date 1/11 at
nitrogen level of (200-250kg N.ha¹).
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.
