Research summary
تهدف هذه الدراسة إلى تحديد الاحتياج المائي لمحصول اليانسون (Pimpinella anisum L.) ومعامل المحصول (kc)، بالإضافة إلى دراسة تأثير الإجهاد المائي على إنتاجية المحصول. تم إجراء التجربة في منطقة دمشق، سوريا، حيث تم تطبيق ثلاثة مستويات من الإجهاد المائي (T1، T2، T3) والتي تمثل 20%، 30%، و40% من كمية الري الكامل (T0) على التوالي. أظهرت النتائج أن الاحتياج المائي لليانسون في المنطقة المدروسة بلغ 4260 م³/هـ، وقيمة معامل المحصول كانت 0.36. كما أظهرت النتائج أن الإنتاجية انخفضت بشكل غير معنوي في المعاملة T1، بينما انخفضت بشكل معنوي في المعاملتين T2 وT3 عند مستوى معنوية 0.05. تم حساب معامل الاستجابة للإجهاد المائي (Ky) والذي بلغ 0.25 و0.79 في المعاملتين T1 وT2 على التوالي. وأظهرت النتائج أن اليانسون يمكنه تحمل الإجهاد المائي إلى حد ما، حيث لم تظهر فروق معنوية في ارتفاع النبات بين المعاملة T0 والمعاملة T1، بينما انخفض ارتفاع النبات بشكل معنوي في المعاملتين T2 وT3 بنسبة 13% و30% على التوالي. خلصت الدراسة إلى أن محصول اليانسون يمكن أن يكون خياراً جيداً في المناطق ذات الموارد المائية المحدودة، حيث يمكن تطبيق الري الناقص بنسبة تصل إلى 30% دون تأثير كبير على الإنتاجية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة ذات أهمية كبيرة في مجال الزراعة، خاصة في المناطق التي تعاني من شح الموارد المائية. ومع ذلك، هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم توضيح كيفية تأثير الإجهاد المائي على جودة الزيت العطري المستخرج من اليانسون، وهو جانب مهم نظراً لاستخدامات اليانسون الطبية والعطرية. ثانياً، كان من الممكن توسيع نطاق الدراسة ليشمل مناطق أخرى ذات ظروف مناخية مختلفة لتعميم النتائج. ثالثاً، لم يتم التطرق إلى تأثير الإجهاد المائي على مراحل نمو النبات المختلفة بشكل مفصل، مما قد يساعد في تحديد الفترات الأكثر حساسية للإجهاد المائي. بشكل عام، تعتبر الدراسة خطوة مهمة نحو تحسين كفاءة استخدام المياه في الزراعة، ولكن هناك مجال لمزيد من البحث والتطوير.

The experiment was conducted for one growing season 2011 at Teezen Research Station in Hama Research Center-GCSAR in order to determine water requirements, crop coefficient (Kc) and the effect of different irrigation systems on productivity of pea nut crop. Four methods of irrigation were used (drip، sprinkler، mini sprinkler and surface irrigation) with three replications for each . Experiment was designed on the basis of randomized complete block with one water treatment (75% out of the field capacity). The results showed superiority of drip irrigation in terms of water consumption, and total water consumption (6522 m 3/h), which led to savings in irrigation water by (60.14%), compared with traditional surface irrigation, with a consumption (13495 m 3/ h). It also outperformed drip irrigation when (p<0.05) in crop yield, reaching productivity 5920 kg/ha, an increase of 22.57%, and total water use efficiency 1.91 kg/m3, compared with the (control) surface irrigation, reaching productivity (4820) kg/ha. Followed by methods for: irrigation sprinkler sprays small, with a water requirement (8999 and 9396 m 3/ h), and the efficient use of water (0.67 and 0.58) kg/ m3, and the percentage of savings in water (36.65 and 31.98%), respectively, compared with surface irrigation traditional Phonology developing did not show significant differences between irrigation methods in terms of the dates of germination, flowering and maturity.
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.
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, n umber 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.

The research aims to determine the water requirements by using drip irrigation, microjet irrigation, sprinker irrigation and surface irrigation for pepper. The study showed the following: • The pepper don’t need to irrigate through mars and april and the first third of may because the effective rainfall is more than the trees water requirement. • The irrigation efficiencies were 0.921, 0.886, 0.868 and 0.70 for drip, microjet, sprinker and surface irrigation, respectively. • the dayly irrigation averages for one plant by field studying were 1.084, 1.132, 1.152, 1.426 liter/day for drip and microjet and sprinkler and surface irrigation, respectively. • By regarding the surface irrigation as witness we can economize of water in one year for one hectare 3595 m3, 3222 m3 and 2858 m3 by using drip, microjet and sprinker irrigation, respectively. • The product quantities were 3995, 3389, 3315, 2910 by using drip, microjet, sprinker, and surface irrigation, respectively.
