Research summary
هدفت الدراسة إلى تقييم تأثير الكثافة النباتية على الغلة البذرية ومكوناتها لصنف الفول القبرصي (Vicia faba) في منطقة جندر الواقعة بين حمص ودمشق خلال الموسم الزراعي 2015-2016. تم زراعة الفول بأربع كثافات نباتية مختلفة (33.3، 16.3، 11.1، 8.3 نبات/م²) باستخدام تصميم القطاعات العشوائية الكاملة. أظهرت النتائج تفوق الكثافة الثالثة (11.1 نبات/م²) في عدد النورات الزهرية، بينما تفوقت الكثافة الرابعة (8.3 نبات/م²) في عدد الفروع الخضرية، عدد القرون، عدد البذور، ووزن البذور على النبات. أما الكثافة الأولى (33.3 نبات/م²) فقد تفوقت في الغلة البذرية. لم يكن للكثافات تأثير معنوي على وزن البذور في القرن ووزن الـ 100 بذرة. توصي الدراسة باستخدام الكثافة الأولى (33.3 نبات/م²) لتحقيق أعلى إنتاجية بذرية في المنطقة المدروسة.
Critical review
دراسة نقدية: تعتبر الدراسة شاملة ومفصلة، حيث تناولت تأثير الكثافة النباتية على عدة مكونات للغلة البذرية. ومع ذلك، كان من الممكن أن تكون الدراسة أكثر شمولية إذا تضمنت تحليلاً اقتصادياً لتكلفة الإنتاج والعائد الاقتصادي لكل كثافة نباتية. بالإضافة إلى ذلك، لم تتناول الدراسة تأثير العوامل البيئية الأخرى مثل نوع التربة وتوافر المياه بشكل كافٍ، مما قد يؤثر على النتائج. كما كان من الممكن أن تكون الدراسة أكثر قوة إذا تم تكرارها على مدى عدة مواسم زراعية لتأكيد النتائج.

This research was carried out through 2015-2016 growing season
belongs to the fourth stability at Gander village located on the
between Homs and Damascus .The aims of this research were to
study the effect of plant density on seed yield and its components
of faba bean (vica faba ) and to investigate the optimum plant
density of this crop in the region.
the experiment was conducted under Syrian coastal conditions to investigate (Vicia
fabaL.), the effect of boron and zinc foliar fertilization on faba bean,either individually or
in combination, by increased rates (0, 0.25, 0.50, 0.75, and 1 kg boro
n / has boric acid, and
zinc at a rate of 0, 0.375, 0.750, 1.125, and 1.5 kg / ha as zinc sulfate). where fababeans
were plantedin plastic pots(15L) in )2013/11/10(and )2014/11/10(.The soil in pots has high
content of calcium carbonate, low boron and zinc content, with pH slightly basic
(representative of the region's soils).
Half boron and zinc fertilizer rates were sprayed after 33 days of germination and the
other half ,after 65 days of germination. The results showed significant responses in all
studied parameters (number of branches,number of pods / plant, weight of 100 seeds, and
seed yield (Kg. / ha) on faba bean plant, as a result of foliar fertilization by boron and zinc.
Fababeans response to boron is higher than to zinc fertilization in all studied
indicators. However,the treatmentB75Zn75(0.75 kg boric acid and 1.125kg of zinc sulfate)
is the best, as compared to others. Also, the driedseeds yield was increased by about
17.66%.
This research was carried out at a special farm at Balghounis - Banias during the
agricultural season 2013/14 to study the of effect plant density and variety and the
interaction between them on some productivity characteristics of faba bean plant.
Two
faba bean varieties were used : Balady (local variety) and Italian Super Simonia (new
variety in Syria). Five densities (20, 10, 6.67, 5, 4) plants/m2 were studied. A split plot
design with three replications was used, in which varieties were assigned to main plots and
densities to sub plots. The GenStat 12 program was used for statistical analyses.
The results indicated that Balady variety significantly surpasses the Italian one in
plant height during maturity stage. Also Balady variety showed a significant increase
compared to Italian variety in number of branches/plant, number of pods/plant and 100-
seed weight. On the other hand, Italian variety significantly surpasses the Balady one in
number of seeds/pod and seed yield, and it showed a significant increase compared to
Balady variety in seed weight per plant. Increasing of plant density led to an increase of
plant height and a decrease of number of branches/ plant, number of pods/plant and
number of seeds/pod. Decreasing of plant density led to decrease of 100-seed weight and
seed yield.
In a study conducted at Research Center of Dara'a, General Commission
for Scientific Agricultural Research during two growth seasons 2007/2008 and
2008/2009. 11 faba bean (Vicia faba L.) populations were planted in an
experiment designed randomize
d complete blocks design with three
replications. The objectives were investigation of phenotypic variance among
populations studied, to determine the relationship among number of yielded
branches plant -1, number of pods plant -1 , number of seeds pod -1, 10- green
pod weight (g) and yield of green pods plant -1 (g) using correlation and path
coefficient analysis. The combined analysis of variance showed highly
significant differences among populations under study and for all
characteristics studied, except number of yielded branches plant-1 where
differences were only significant. The correlation and path analysis studies
revealed that negative and highly significant relationship was found between
number of yielded branches plant -1 and yield of green pods plant-1, while was
positive and highly significant between yield of green pods plant-1 and 10-green
pod weight. All direct effects of components studied were negative in both
seasons, except 10-green pod weight, and these results suggested adopting the
last component as a selection index during making selection of high yielding
genotypes in faba bean populations. .
This study was conducted at AL-buyarat AL-garbya, west Palmyra during
2010/ 2011 and 2011/2012 growing seasons to determine the optimum date and
plant density for sowing two faba bean varieties. The studied factors were two
sowing dates (15/10 and
5/11), plant densities (16.7 and 11.1 plants/m2) and two
varieties of faba bean (kobrusi and Hama1). Results showed that sowing on
early date 15/10 resulted in increasing plant height, number of branches/plant
and pod length as compared with 5/11 sowing date.
