نُفذ البحث خلال الموسم الزراعي 2014-2015 م في محطة البحوث الزراعية في الكريّم في منطقة السلمية التابعة لمحافظة حماه و ذلك لبيان تأثير الكثافة النباتية على مدة الأطوار الفينيولوجية لنبات العدس مقدرة باليوم و كذلك لمعرفة تأثير الكثافة النباتية على انتاجية نبات العدس من البذور ( غ/ نبات ) و إنتاجية الهكتار الواحد ( كغ / هـ ) و على النسبة المئوية للبروتين في البذور . تم استخدام ثلاث كثافات هي ( 200- 250-300 بذرة / م2 ) و صُممت التجربة بطريقة القطاعات العشوائية الكاملة و بثلاث مكررات لكل كثافة . أظهرت النتائج تفوق نباتات الكثافة المنخفضة ( 200 بذرة / م2 ) معنوياً على نباتات الكثافة ( 250 بذرة / م2 ) و على نباتات الكثافة ( 300 بذرة / م2 ) في صفة التبكير بالوصول الى 50 % من الانبات حيث بلغت على التوالي ( 19.4-20.5-22.5 يوم ) و كذلك في مرحلة الإزهار حيث بلغت على التوالي ( 111.36-113.6-114.7 يوم ) و كذلك في مرحلة النضج حيث بلغت على التوالي ( 134.4-136.6-137.7 يوم ) و تفوقت نباتات الكثافة ( 200 بذرة / م2 ) على نباتات (250 بذرة / م2) و ( 300 بذرة / م2 ) معنوياً بإنتاجية البذور على مستوى النبات الواحد أو بلغت على التوالي ( 1.553-1.487-1.376 غ / النبات ) . أما بخصوص إنتاجية وحدة المساحة من البذور فقد تفوقت الكثافة ( 300 بذرة / م2 ) معنويا على كثافة ( 250 بذرة / م2 ) و( 200 بذرة / م2 ) حيث بلغت على التوالي ( 1791.3-1492.7-1194.2 كغ / هـ ) . و تفوقت الكثافة ( 200 بذرة / م2 ) معنويا على الكثافة ( 250 بذرة / م2 ) و على الكثافة ( 300 بذرة /م2 ) في نسبة البروتين حيث بلغت على التوالي ( 26.8-26.3-26.19 % ).
This search was conducted during 2014-2015 growing season in Agricultural research station in Al Kraeim belonging to Al Salameah district in Hamah Provence in order to study the effect of plant density on; First, the phenological stages of lentil plant calculated in day unit. Second, the seed productivity in a lentil plant calculated in g/plant, and then seed production in Hectares (Kg/ha-1).Lastly, percentage of seed protein content in seeds. In this study, three plant densities were used (200, 250, 300 seeds/m2, and was designed using Randomized Sectors in three replicates for each density. Results showed that; 1) The low density plants (200 seeds/m2) was significantly better than other densities (250 and 300 seeds/m2) in: Reaching 50% seed germination (19.4, 20.5 and 22.5 day continually) and in flowering stage (111.36, 113.6 and 114.7 day continually) and in maturation/Ripening stage (134.4, 136.6 and 137.7 day continually). Seed production per plant (1.553g/plant) in comparison by seed production of other densities (1.487 and1.376 g/plant). Percentage of seed protein (26.8%) in comparison by seed protein of other densities (26.3 and 26.19 %). 2) The higher densities (300 seeds/m2) was better in seed production in aria unit (1791.3 Kg/ha-1) in comparison by production of other densities (1492.7 and 1194.2 Kg/ ha-1).

Agriculture led on the first date (December 15) and in the
plant a minimum density (200 seeds / m2) increased to varying
significantly different in the length of the century / mm and the
total number of horns on a per plant and the number of seeds per
plant and seed weight on a per g / plant and seed weight per hectare
And it gave the plant Top-density (300 seeds / m 2) a significant
increase in the weight of centuries per g / plant and the number of
pods on the plant and the weight of Aalakec per hectare and
biological weight per hectare.
The lack of information about the cultivation of coriander plant in Syria prompted us
to study the effect of four plant densities (33.33،10، 13.33 and 20 plant/m2)، and four levels
of phosphate fertilization (0107.2،160.8، and 214.4 of Superphospha
te 46%) on some
productive and quality traits of the coriander plant. This study was carried out in Tartous
province during the growing season 2014، using Randomized Complete Block design with
a Split Plot arrangement of treatments. The Results revealed that there were significant
differences between the treatments for the whole traits، in addition to a significant
interaction between density and phosphate fertilization. Although the densities (10، 13.33
and 20 plant/m2) varied in their effect، they had superiority upon the
control(33،33)plant/m2، and the density 10 plant/m2 had more important effect in terms of
increasing each of: branches number/plant، seed weight/plant، seeds number/inflorescence،
protein content in plants and seeds and beta carotene and chlorophyll. However، the level
160.8k.g/h of P2O5 increased the number of inflorescences/plant، number of fruits/plant
and seed weight/ inflorescence.
