نفذ هذا البحث في مزرعة كلية الزراعة بجامعة دمشق خلال العامين 2012 و 2013 بهدف إظهار مدى تأقلم 5 طرز وراثية من العصفر لظروف الزراعة التكثيفية في دمشق تحت تأثير معدلين سماديين من الآزوت إضافة للشاهد دون تسميد آزوتي, و أثر ذلك في صفات نبات العصفر الشكلية و الغلة من البذور.
This search was carried out in the farm of faculty of Agriculture- Damascus during 2012-2013 to determine the adaption of five Safflower genotypes) Farming conditions in the lug intensive in the province of Damascus under the effect of different nitrogen fertilizers and witness without fertilization N3 . And how they affected safflower accessions morphological traits and productivity.

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.
A field experiment was carried out at Abi Jarash farm, Faculty of Agriculture, Damascus University, during the two agricultural seasons 2011-2012/2013-2014 in order to evaluate the performance of some oily varieties introduced from the safflower crop
(SON-4, SON5, PI133055, Local Witness, GILA) under the influence of environmental conditions. Prevalent in Damascus governorate during the spring and summer season (intensive) after harvesting the wheat crop) using two rates of nitrogen fertilizer (control - without adding fertilizer, and at a rate of 75 and 150 kg. ha - 1 pure nitrogen unit)
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.
The research was carried out during 2011-2012 in order to study the effects of five
levels of fertilization (mineral fertilization N:65 P:65 K:70kg/h, and organic fertilization 5,
10 and 15ton/h), three spaces between rows (50, 75, and 100cm), one
15cm space between
one plant and another, and the interaction between them on the production of safflower dry
colored leavel, seed, and oil.
The study showed the following results: all the levels of the studied fertilization were
significantly superior in the production of dry colored leavel, seed and oil over the control.
However, there were no positive differences in the proportion of oil between the treatments
of fertilization and the control.
The 100cm farming space among rows led to a significant positive effect in the
production of safflower seeds, while the 50cm distance among farming rows in the
production of dry coloring leaves was superior over 100cm and 75cm distance. There were
no positive differences in the proportion of oil; while the mean of oil productivity came
down whenever the plant spacing increased from 50 to 75 and then 100cm.
The interaction between the levels of the studied fertilization and agricultural plant
spaces gave a positive significant effect in most studied characteristics. The most
significant positive effect was for the interaction between the mineral fertilization and
100cm distance, and then came the average of the organic fertilization 15ton/h and 100cm
space between rows.
This study was conducted at the vegetable field of department of
horticulture and landscape design, college of agriculture and forestry ,Mosul
university, during spring of 2007 and 2008, to study the effect of times and
levels of nitrogen fertiliz
ation on some characters vegetative growth, flowering
,and yield of summer squash .Result indicated that, the time of nitrogen
fertilization at the stage of fruit-set caused a significant increased in the leaf
number /plant ,length of the plant and the fresh weight/plant. While the time of
nitrogen fertilization wasn't affected significantly the total yield. The level at
320 kg.N/ha caused a significant increase of the characters vegetative growth
and total yield. Also result revealed that, the interaction between the stage at
fruit set and nitrogen fertilization at 320 kg.N/ha led to increase the total yield
.The yield was found to positively correlation with the plant length ,fresh and
dry weights of plant, leaf area, fruit weight, male and female flowers, and the
sex ratio.
