نفذ البحث خلال الموسم الزراعي 2014 في سهل البقيعة في المنطقة الغربية من محافظة حمص، لدراسة تأثير عدة أنظمة للزراعة التحميلية في نمو و انتاجية و معدل استغلال الأرض لمحصولي الذرة الصفراء و فول الصويا و هي: (خط ذرة صفراء + خط فول صويا)، (خط ذرة صفراء + خطين فول صويا)، (خطين ذرة صفراء + خط فول صويا)، (خطين ذرة صفراء + خطين فول صويا)، (محصول الذرة الصفراء منفرد)، (محصول فول الصويا منفرد).
This research was carried out during the agricultural season 2014 in the Buqai'a plain in west of Homs governorate, to study the effect of several systems for intercropping on Corn crop (Zea mays L.( and Soybean crop (Glycine max L.): (Zea mays line : Soybean line) (Zea mays line : Two Soybean lines) (Two Zea mays lines + Soybean line) ( Two Zea mays lines + Two soybean lines) (Single Zea mays crop), (Single soybean crop).

The study was carried out at Abo Jarash farm, Faculty of Agriculture,
Damascus University, during the growing season of 2012, where the maize
cultivar "Gouta 1" was grown in three agricultural spacings (20, 30 and 40 cm
between plants in the same
row), with a fixed space (70 cm) between rows,
according to the randomized complete block design and three replicates per
treatment, in order to study the effect of the studied agricultural spacing on the
following characters: plant height, length and weight of ear, number of kernel
rows per ear, number and weight of kernels per ear, net percentage, hundred
kernels weight, the kernel yield, the dry yield and the oil and protein contents
in the kernels. Results showed a significant decrease in plant height from
155.31 to 130.10 cm, while a significant increase was observed in number of
kernels per ear (from 310.05 to 373.82 kernels), in weight of kernels per ear
(from 41.20 to 65.17 g) and in net percentage (from 61.61 to 91.51 %),
respectively with the increase of agricultural spacing from 20 to 40 cm.
However, the increase in these characters didn’t substitute the small number of
plants in the vast spacing compared with the narrow spacing, which is reflected
in kernel yield per unit of area that amounted to 3.19 and 2.04 tons/ha,
respectively.
The research was carried out using 1728 broiler chicks (shifer starbro
hybrid), They were divided into eight groups, each one consists of three
replicates with 72 birds in every repetition .The birds of all repetitions were
fattened until 49 days
in separate pen of open type walk ,and on deepbedplate
.All conditions of placement, rearing and feeding were the same for all birds of
repitition in different groups.
This study was conducted at the farm of the Faculty of Agriculture in
Kharabo during 2011 2012 growing season. RCB design with two replicates was
used and the correlation and regression relationship among characters were
tested. Results showed tha
t plant and ear heights were both positively
correlated with some quantitative characters (number of kernels per row،
number of rows per ear, 100 kernel Wight, and kernels weight per ear).
Regression results also showed that the increase in plant and ear height was
associated with an increase in number of rows per ear, kernels weight per ear
and 100 kernel wight. It was concluded that plant height and/or ear height can
be used as a direct selection index for number of rows per ear, kernels weight
per ear and 100 kernel wight.
The research was executed within the season 2016, in the west of
HOMS in the first settlement area.
The study has showed the effect of plant density and nitrogen
fertilization was studied on the growth and productivity of soybeans
Glycine max L . (Sb44).
This study was conducted in Abu-Jarash farm at the Faculty of Agriculture,
Damascus University during the main season 2013 to evaluate the effect of soil
solarization and organic fertilization treatments on the productivity of some
maize genotypes
(Basel 1, Basel 2, Ghouta 1, Ghouta 82 and Local White). The
experiment was laid out according to split-split plot design with three
replications. The statistical analysis results clearly indicated to the existence of
variability in the response of studied maize genotypes to soil solarization and
organic fertilization treatments. The genotype Ghouta 82 surpassed in the traits
of plant height, leaf area index, 100-kernel weight and grain yield (150.25 cm,
2.84, 28.10 g and 7.99 ton.ha-1) respectively, as compared to other studied
genotypes and was closely followed by the genotype Basel 2 which recorded the
highest number of rows per ear (13.83 row/ear). Soil solarization for 45 days
before sowing and applying organic manures at the rate of 20 ton.ha-1
encouraged the traits of plant height, leaf area index, number of rows and
grains per ear, 100-kernel weight which was reflected on grain yield. Therefore
we can grow variety Ghouta 82 or hybrid Basel 2 to get higher yield of maize.
