This research was carried out during 2009/2010 growing season in
swiri region which locates about 30 Km at the west of Homs city ,
located in the first stability region where the annual precipitation is
about 400 mm .
One cultivars of faba (Vicia
faba) was sown on three seeds rate
(high seed rate 220 kg/h – medium seed rate 185 kg/h – low seed
rate 150 kg/h) and three sowing date (15/11 – 30/11 – 15-12 ) 2009.
This research was conducted at Tal Shnan village, located at the eastern of Homs
city, Syria during 2012/ 2013 growing season, using hard local wheat cultivar,
Sham 5, to study the effect of seed rates (120, 150, 180, 210 kg/ha), spray with
differ
ent parts of sorghum water extracts using different, and weeding on wheat
yield and weeds accompany with the crop.
This research was carried out at the farm of Faculty of Agriculture,
Damascus University, during 2010-2011 growing season to determine the effect
of seedling rate on yield traits (plant number at harvesting, plant height,
number of umbels/plant, n
umber and weight of seeds/ umbel, plant dry weight,
seed yield and harvest index.) of four ecogenotypes of Anise plants, (Pimpinella
anisum L.) collected from different places of Syria: Damascus countryside
(Hena, Saasaa), Homs and Edlib. Sowing rates were 10, 15 and 20 Kg/ha.. Trial
was laid out using completely randomized block design with three replicates for
each treatment. Results showed that studied traits differed according to seeding
rate and the ecotype. There were significant differences for the treatment of
seeding rate of 15 kg/ha., on seed yield. Regardless the ecotype, increasing the
seeding rate up to 20 kg/ha. resulted in maintenance of highest number of
plants/unit area, but accompanied with reduction in fertile umbels and seed
weight. Statistical analysis showed that the ecotype of Edlib recorded the
highest seed weight/ plant and highest seed yield/ planted area, especially with
the seeding rate of 15 kg/ha. However, the results showed the seed components
of Anise (plant number at harvesting, weight of seeds/ plant) and seed yield
were affected by the ecotype and seeding rate.
A field experiment was conducted on sandy loam soil under the irrigation
conditions in Deir- ezzor during the years of ١٩٩٨ and ١٩٩٩ to study effect of
planting time and seed rate on growth and productivity of tow varieties of rape
crop Brasica napous var. oleifera (Bromin & VEM).
