The research was carried out in the agricultural season 2016-2017 the village of DweirRaslan Tartous governorate with three planting dates (20 November - 10 December - 1 January) and three densities (12 - 14 - 16 plants / m2) Where the planting time was the main pieces and the plant density occupied the dissecting pieces once to study the effect of planting date and plant density on some morphological characteristics of white thermos plant. The results showed that dates of the early dates (November 20) were higher in plant height, with an average of 64 cm and surface area of the paper surface at an average of 24.367 thousand. M 2 / ha and in shape of the length of the century with an average of 7.50 cm. As for the plant density, the plants of density12 plants / m 2 in the height of plant exceeded an average of 65.6 cm and length of the century with an average of 8.13 cm, while the plants of density 16 plants / m 2 in the area of paper area average 24.213 thousand.

Research summary
أجريت هذه الدراسة في الموسم الزراعي 2016-2017 في قرية دوير رسلان بمحافظة طرطوس، بهدف دراسة تأثير موعد الزراعة والكثافة النباتية على بعض الصفات المورفولوجية لنبات الترمس الأبيض البلدي (المر). تم استخدام ثلاثة مواعيد للزراعة (20 تشرين الثاني، 10 كانون الأول، 1 كانون الثاني) وثلاث كثافات نباتية (12، 14، 16 نبات/م²). صممت التجربة بطريقة القطاعات العشوائية المنشقة، حيث شغلت مواعيد الزراعة القطع الرئيسية وشغلت الكثافة النباتية القطع المنشقة. أظهرت النتائج تفوق نباتات الموعد المبكر (20 تشرين الثاني) في صفة ارتفاع النبات بمتوسط 64 سم، ومساحة المسطح الورقي بمتوسط 24.367 ألف م²/هـ، وطول القرن بمتوسط 7.50 سم. أما بالنسبة للكثافة النباتية، فقد تفوقت نباتات الكثافة 12 نبات/م² في صفة ارتفاع النبات بمتوسط 65.6 سم وطول القرن بمتوسط 13.13 سم، بينما تفوقت نباتات الكثافة 16 نبات/م² في صفة مساحة المسطح الورقي بمتوسط 24.213 ألف م²/هـ. توصي الدراسة بزراعة الترمس الأبيض في الموعد (20 تشرين الثاني) وبكثافة نباتية 16 نبات/م² عند استخدامه كعلف أخضر في مرحلة الإزهار، وبكثافة نباتية 12 نبات/م² للإنتاجية البذرية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في تسليط الضوء على تأثير مواعيد الزراعة والكثافة النباتية على نبات الترمس الأبيض البلدي في ظروف الساحل السوري. ومع ذلك، يمكن تقديم بعض الملاحظات النقدية لتحسين الدراسة. أولاً، كان من الممكن توسيع نطاق الدراسة لتشمل مناطق أخرى في سوريا لتعميم النتائج بشكل أفضل. ثانياً، لم تتناول الدراسة تأثير العوامل البيئية الأخرى مثل التسميد ونوعية التربة بشكل مفصل، مما قد يؤثر على دقة النتائج. ثالثاً، كان من الممكن استخدام تقنيات تحليلية أكثر تطوراً لزيادة دقة البيانات المستخلصة. وأخيراً، كان من الأفضل تضمين توصيات أكثر تفصيلاً حول كيفية تطبيق النتائج في الزراعة العملية.

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.
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.
We evaluated some of the qualities of productivity for lentil variety ( Lens esculanta ) Idlib2 in the province of Hama, which lies within the third zone in the two seasons 2013- 2014. manner random sectors dissident once and three replications fo r each worker where she planting dates widget Home and operated plant density widget dissident once in order to determine the date and density suitable to reach the best production of lentils in a peaceful area. 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.
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.
The research was conducted during the growing season in 2013- 2014 in Bssiren Hama. In a split- plot design: the varieties were main plots (asgro, rama, Muncipal) and the sowing dates were subplots (15\11;30\11;15\12 and 30\12) and the densities we re subplots (20 plant\m2, 13.33 plant\m2). The early planting went to Significant increase in the days to germination, long time of fruit; the number of days to flowering and the number of days to fruiting; Plant height; Number of branches plant ; weight of pod; number of pods plant; dressing percentage; Yield of green pods plant and Yield of green pods. While the high density was observed Significant increase in the Plant height; Number of branches plant; weight of pod; number of pods plant; and Yield of green pods plant, while the low density was observed Significant increase in the Yield of green pods. The Asgro variety was obtained at Rama and Muncipal varieties in the number of branches plant; number of pods; Yield of green pods plant and, while the Rama variety was obtained by the plant height, and non- significant results were found among varieties by the weight of pod. The positive results also showed in the interaction among factors.
