This search was conducted in Albassa town at Lattakia governorate , during 2011 and 2012 growing seasons for study effects of 3 sowing dates ( 15th of April , 25th of April and 5th of May ) and 4 levels of nitrogen fertilization ( N1: control , N2: 50 kg/ha , N3: 100 kg/ha , N4: 150 kg/ha ) on several attributes of groundnut (Coastal category) production . The results showed that the 5th of May sowing date had significant excel in the average of the two growing seasons in dry weight of pods in plant , wheight 100- Seeds, The per-hectare yield of seeds and Harvest index , It ranked first in the two seasons search. Also, The application of nitrogen fertilizer at a rate of 150 kg/ha had resulted in a significant increase in studied productivity traits in the average of the two growing seasons , Except for harvest index , which was at least as compared to other levels of fertilization. The interaction between the sowing date ( 5th of May ) and the level of nitrogen fertilization (150 kg/ha) showed a significant excel in the average of the two growing seasons in dry weight of pods in plant , wheight 100- Seeds and The per-hectare yield of seeds .

Research summary
يهدف البحث إلى دراسة تأثير مواعيد الزراعة ومستويات التسميد الآزوتي على بعض الصفات الإنتاجية للفول السوداني (الصنف الساحلي) في منطقة البصنة بمحافظة اللاذقية خلال الموسمين الزراعيين 2011 و2012. تم اختبار ثلاثة مواعيد للزراعة (15 نيسان، 25 نيسان، و5 أيار) وأربعة مستويات من التسميد الآزوتي (0، 50، 100، و150 كغ/هكتار). أظهرت النتائج أن موعد الزراعة في 5 أيار مع التسميد الآزوتي بمعدل 150 كغ/هكتار حقق أفضل النتائج من حيث وزن القرون الجافة، وزن المئة بذرة، وإنتاجية وحدة المساحة من البذور. كما أظهرت الدراسة أن التسميد الآزوتي بمعدل 150 كغ/هكتار أدى إلى زيادة معنوية في الصفات الإنتاجية المدروسة باستثناء دليل الحصاد الذي كان الأقل مقارنة بمستويات التسميد الأخرى. توصي الدراسة بزراعة الفول السوداني في 5 أيار وإضافة السماد الآزوتي بمعدل 150 كغ/هكتار لتحقيق أعلى إنتاجية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة لأنها تسلط الضوء على تأثير مواعيد الزراعة والتسميد الآزوتي على إنتاجية الفول السوداني، وهو محصول ذو أهمية اقتصادية وغذائية. ومع ذلك، يمكن أن تكون الدراسة أكثر شمولاً إذا تم تضمين المزيد من المتغيرات البيئية مثل نوعية التربة ودرجة الحرارة والرطوبة. كما أن الدراسة اقتصرت على منطقة واحدة، مما يجعل من الصعب تعميم النتائج على مناطق أخرى ذات ظروف بيئية مختلفة. بالإضافة إلى ذلك، كان من الممكن أن تكون الدراسة أكثر فائدة إذا تضمنت تحليلاً اقتصادياً لتكاليف وفوائد استخدام مستويات مختلفة من التسميد الآزوتي.

This study was carried out during the growing season of 2015 to study effect od three planting date (1 Feb., 15 Feb. and 1 March) and four levels of nitrogen fertilization (0, 40, 60 and 80 kg/Ha) with interactive effect between them on some yield components of cumin.
This study was conducted at the vegetable field of department of horticulture and landscape design, college of agriculture and forestry ,Mosul university, during spring of 2007 and 2008, to study the effect of times and levels of nitrogen fertiliz ation on some characters vegetative growth, flowering ,and yield of summer squash .Result indicated that, the time of nitrogen fertilization at the stage of fruit-set caused a significant increased in the leaf number /plant ,length of the plant and the fresh weight/plant. While the time of nitrogen fertilization wasn't affected significantly the total yield. The level at 320 kg.N/ha caused a significant increase of the characters vegetative growth and total yield. Also result revealed that, the interaction between the stage at fruit set and nitrogen fertilization at 320 kg.N/ha led to increase the total yield .The yield was found to positively correlation with the plant length ,fresh and dry weights of plant, leaf area, fruit weight, male and female flowers, and the sex ratio.
It is well established that sugar content of sugar beet increases as the plant reaches the biological maturity stage. This means that the sugar beet plant must be left in the field to complete its growth. Farmers are usually concerned with the hig hest yield of sugar beet roots regardless of their content of sugar, but sugar-processing companies are concerned mainly with the amount of sugar extracted from a certain weight of roots, in addition to the purity of the sugary juice. Farmers normally receives the price of their sugar beat crop based on the sugar content of the crop. Thus, in this type of farming, biological control is a worldwide-procedure. Biological maturity depends on ways of yield formation and a close control of the mechanisms of forming yield components (no. of roots / unit area; average root weigh; average sugar content) which require a detailed study of the characters of the grown cultivar and the overall conditions of the growing area. Results showed that harvesting of sugar beet sown in fall season befor the plant completes it’s growing cycle (in June) results in a big yield in addition to a reduction in sugar content in the roots which inturn results in a big loss in the national economy. Results indicated that delaying date of harvest up to ١٨th of July markedly increased root and sugar yield as well as sugar content in the beet roots. Increasing nitrogen rate up to ٤٠٠ kg / ha resulted in a marked increase in root and sugar yield / ha . On the other hand, sucrose content gradually decreased with excess nitrogen. Higher plant density (more than ١٠٠,٠٠٠ plants /ha) enforce for late harvesting in comparison with other densities for at least ١٠ days to obtain high yield of roots and sugar.
The study included the selection of the best methods to extract the enzyme among nine methods. The protein content was concentrated and precipitated by cold acetone among other five methods of concentration (partial purification). The purification stages were achieved by using ion exchange column chromatography (DEAE – Sephadex A 50 column). Followed by gel filtration chromatography using sephacryl S-300. The active parts were lyophlizated (free drying) to obtain Lipoxygenase with 43.18% yield and 8.16 folds of purification and specific activity of 1162.9 unit / mg. The purity of enzyme was confirmed by poly acryl amide gel electrophoresis under non denaturing conditions, with the appearance a single band .
The research was conducted during the agricultural seasons 2016,2017 m in the Syrian coast in Tartous governorate, the village of Beit Sheikh Yunus. To study the effect of organic and chemical fertilization on some productive traits (number of flow er/plant, fruit weight /plant, weight of 1000 fruit gr, fruit yield Kg/h, harvest index%) of Coriander plant.
