نفذ هذا البحث في الموسم الزراعي 2015 في المنطقة الغربية من محافظة حمص ( قرية المزينة ), حيث تقع ضمن منطقة الاستقرار الأولى, زرع صنف الحمص الفرنسي في منتصف شهر كانون الثاني على ثلاث مسافات زراعية ( 15, 8, 4 ) سم و تم إضافة الأسمدة الآزوتية على ثلاث مستويات ( 50, 25, 0 ) كغ على دفعتين. و قد بينت النتائج وجود تأثير لإضافة الأسمدة الآزوتية مع تغير المسافات الزراعية على بعض الصفات المدروسة. و بناء على نتائج البحث تم التوصل إلى ما يلي: أعطت المسافة 15 سم مع إضافة الأسمدة 50 كغ/ه أعلى قيمة في صفة وزن البذور على النبات, بينما أعطت المسافة 4 سم مع إضافة الأسمدة الآزوتية بمعدل 25 كغ/ه أعلى قيمة في ارتفاع النبات و ارتفاع أول قرن, و تم الحصول على أعلى قيمة في صفة الغلة الحيوية و الغلة من القش عند مسافة 8 سم و إضافة أسمدة آزوتية بمعدل 25 كغ/ه, و لم يكن هناك أي تأثير واضح لإضافة الأسمدة الآزوتية في الغلة البذرية.
The research was executed within the season 2015 ,in the west of HOMS in the first settlement area.One kind (Alfarancy) of chick pea Cicer arietinum L, was sowed in January on three planted distances (4,8,15) cm, and three application rates of Urea fertilizer (N 46%) were applied (0,25,50) kg/ha each level was applied with two equal patches. Most results showed that the difference of the distances with difference rate of Urea fertilizer has a big effect on the most studied qualities. Depending on the research results we founded that:The seeding with 15 cm and applying 50 kg n/h surpassed most the other treatment for seed weight for each plant, Results also indicated that the seedling with (4cm with 25 kg/h) surpassed most the other treatment for (high plant, high first pod). For characteristics (biological yield, straw yield) that the seedling with (8cm with 25 kg/h) surpassed most the other treatment. There was no effect to applying fertilizer on seed yield.

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 research was conducted in Bsiereen village of Hama province.
The objective of this research was to identify the optimal plant
density for the two varieties of garlic, namely Kiswany and Kurdy.
A split plot design was used in this experiment.
Kiswany and
Kurdy were considered as the main factor while the treatments of
the experiment were considered as a split factor [( 5 treatments for
plant density: plating on lines: with four treatments (10 × 20, 15 ×
20, 10 × 25, and 15 × 25), planting on both lines sides with a
distance of (10× 45 cm)]. The total replicates for each treatment
was three with an average of 10 plants for each replicate. The Gen
Stat 32 was used for the analysis of data and the LSD was
calculated at p≤ 0.05. The result of analysis shows the followings: -
Kiswany plants superseded Kurdy plants almost for all growth
indicators and this was reflected positively in its productivity. -
Treatment number 5 (planting on both sides of the line: 10 × 45 cm)
has proven to show the best results for almost all the studied
characteristics and indicators. -The interaction of a variety with
treatment 5 affected positively most of the characteristics of the
total green parts of the plants for both varieties of the treatment.
This was reflected as an increases in their productivity. - An
increases in a plant density for treatment one for Kiswany (planting
on lines: 10 × 20 cm) has increased the productivity but this was
not the case for Kurdy variety.
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 study was carried out in the nursery gardens of Tishreen University in the
early spring period in 2014, to study the effect of different levels of dry organic manure in
the growth and productivity of potato plants (class Spunta), in randomized
complete
design, study included six treatments: control ( cow organic manure amount of 4 kg/m2)
and five treatment with five levels of dry organic manure (100-150-200-250-300 g/m2)
.The results showed an increase in stem height, number of stem, foliage area, production
and percent of standard tubers by adding dry organic manure at level of 250 g/m2 while
Treatment with 300g/m2 contributed an increase of folige area, height of plant and stem
number while causing reduced plant production,tuber average weight and production of
standard tubers.The result showed also no significant differences between the control and
the treatment of 250 g/m2dry organic manure in each of the folige area, production and
standard tubers
Objective of this work was to investigate how plant density and nitrogen
rate affects the growth , yield and its components in maize (Bassel 2 hybrid).
The experiment was carried out, at the agricultural research centre in Snoubar
Jableh, during t
he 2008 and 2009 seasons, included 12 treatments which were
the combination three plant population densities 71428/ha, 57142/ha, and
47619/ha and four N rates (0, 60, 120 and 180 kg/ha). The experimental design
was a split-plot, with different densities as main plots, randomized in three
complete blocks, and the fertilization as subplots. The data were analyzed by
using “Mstat” statistical package. Increasing planting population density
delayed anthesis and silking date, increased the anthesis-silking interval, plant
height, ear height, grain yield, agronomic nitrogen efficiency and nitrogen use
efficiency, but decreased ear leaf area, chlorophyll content, 1000 seed weight,
number of grains/ear, shelling percentage (%), and grain protein content.
Nitrogen fertilizer decreased tassilling and silking date, and nitrogen use
efficiency, increasing plant and ear height, ear leaf area, chlorophyll content,
number of grains/ear, ear weight,1000-grains weight, Shelling percentage,
grain yield up to 120 kg N/ha, agronomic nitrogen efficiency and grain protein
content.
