البحث في مزرعة أبي جرش التابعة لكلية الزراعة - جامعة دمـشق خـلال الموسـم الزراعـي 2010/2011 بهدف تحديد تأثير معدل البذار في مؤشرات الغلة لأربعـة طـرز بيئيـة مـن اليانـسون (.L anisum Pimpinella) حصلّ عليها من مناطق بيئية مختلفة من القطـر؛ ريـف دمـشق (حينـة و سعسع، و حمص و إدلب، وزرعت بثلاثة معدلات للبذار (10 ،15 ،20 كغ/هكتار)، و وزعـت المعـاملات وفق تصميم القطاعات العشوائية الكاملة و بثلاثة مكررات. و أخذت القراءات الآتية: عـدد النباتـات فـي مرحلة الحصاد، و ارتفاع النبات، و عدد النورات/ نبات، و عدد البذور و وزنها/ نبات، و الغلة مـن البـذور. أظهرت النتائج اختلاف قيم الصفات المدروسة تبعاً لمعدل البذار و للطراز البيئي، إذْ تفوق معدل البذار 15 كغ/ هكتار معنوياً في الغلة من البذور بغض النظر عن الطراز البيئي المستخدم. أدت زيادة كميـة البـذار المستخدمة حتى 20 كغ/ هكتار إلى المحافظة على أكبر عدد من النباتات بوحدة المـساحة فـي مرحلـة الحصاد مترافقاً بانخفاض في عدد النورات الممتلئة، و وزن البذور في النبات، كما أشارت نتائج التحليـل الإحصائي إلى تميز الطراز البيئي، إدلب بأعلى وزن للبذور في النبات، و بأعلى مردود مـن البـذور فـي وحدة لمساحة و لاسيما عندما زرع بمعدل بذار 15 كغ/ هكتار. عموماً، أوضحت نتائج البحث تأثر مكونات الغلة في نبات اليانسون (عدد النباتات في مرحلة الحصاد، و وزن البذور من النبات)، و الغلة مـن البـذور بالطراز البيئي و بمعدل البذار المستخدم.
This research was carried out at the farm of Faculty of Agriculture, Damascus University, during 2010-2011 growing season to determine the effect of seedling rate on yield traits (plant number at harvesting, plant height, number of umbels/plant, number and weight of seeds/ umbel, plant dry weight, seed yield and harvest index.) of four ecogenotypes of Anise plants, (Pimpinella anisum L.) collected from different places of Syria: Damascus countryside (Hena, Saasaa), Homs and Edlib. Sowing rates were 10, 15 and 20 Kg/ha.. Trial was laid out using completely randomized block design with three replicates for each treatment. Results showed that studied traits differed according to seeding rate and the ecotype. There were significant differences for the treatment of seeding rate of 15 kg/ha., on seed yield. Regardless the ecotype, increasing the seeding rate up to 20 kg/ha. resulted in maintenance of highest number of plants/unit area, but accompanied with reduction in fertile umbels and seed weight. Statistical analysis showed that the ecotype of Edlib recorded the highest seed weight/ plant and highest seed yield/ planted area, especially with the seeding rate of 15 kg/ha. However, the results showed the seed components of Anise (plant number at harvesting, weight of seeds/ plant) and seed yield were affected by the ecotype and seeding rate.

Aniseed Crop, Pimpinella anisum L. is one of the important medicinal and
aromatic plants in Syria and the world. It has very important economic value,
appear in its medicinal and multi-uses. Weeds considered as the greatest
obstruct for aniseed pr
oduction and hand picking is commonly used for weed
control. So the investigation was carried out to evaluate the effect of the
herbicide, Afalon on the weeds of aniseed and its phytotoxicity. Afalon
treatment resulted in high efficacy for the broad leaves weeds (92.4 %, 97.1 %
and 96.1 %) for the half rate, field rate and double field rate, respectively and
(5.8 %, 23.9 % and 29.1 %) for the narrow weeds. The treatment of double
field rate gave a high yield (715.3 Kg/ha.) that was equal to weeded plots (777.8
Kg/ha.), and the field rate treatment (673.6 Kg/ha.) was significantly superior
to other treatment. This indicated the importance of spraying aniseed crop with
Afalon especially when hand picking not possible. Phytotoxicity effect were not
recorded on anise plants. Some other plants were not affected by the herbicide
like Ammi majus and coriander, those are belong to the same family, Apiaceae.
The study aimed to estimate water requirements for Anise, the crop
