Research summary
تأثير مواعيد الزراعة ومعدلات التسميد الآزوتي على بعض مكونات الغلة لنبات الكمون هو موضوع دراسة نفذت خلال الموسم الزراعي 2015. تم اختبار ثلاثة مواعيد للزراعة (1 شباط، 15 شباط، و1 آذار) وأربع مستويات من التسميد الآزوتي (0، 40، 60، و80 كغ/هـ). النتائج أظهرت أن موعد الزراعة في 1 آذار حقق زيادة معنوية في معظم مكونات الغلة باستثناء عدد البذور في النورة. كما أن التسميد الآزوتي بمعدل 80 كغ/هـ أدى إلى زيادة معنوية في جميع مكونات الغلة. التداخل بين موعد الزراعة الثالث ومعدل التسميد الآزوتي الرابع أعطى أعلى ارتفاع للنبات وعدد فروع ونورات. الدراسة أوصت بالزراعة في 1 آذار مع استخدام التسميد الآزوتي بمعدل 80 كغ/هـ لتحقيق أفضل إنتاجية.
Critical review
دراسة نقدية: الدراسة قدمت معلومات قيمة حول تأثير مواعيد الزراعة ومعدلات التسميد الآزوتي على نبات الكمون، ولكن هناك بعض النقاط التي يمكن تحسينها. أولاً، الدراسة لم تأخذ في الاعتبار تأثير العوامل البيئية الأخرى مثل الرطوبة والرياح التي قد تؤثر على النتائج. ثانياً، كان من الممكن توسيع نطاق الدراسة ليشمل مناطق جغرافية مختلفة لضمان تعميم النتائج. ثالثاً، لم يتم مناقشة الجوانب الاقتصادية بشكل كافٍ، مثل تكلفة التسميد والعائد الاقتصادي للمزارعين. أخيراً، كان من المفيد تضمين تحليل طويل الأمد لتأثير التسميد الآزوتي على التربة وصحة النبات.

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 .
The research was Carried out in Jisr area in the province of Idlib during the growing season 2013 - 2014 to study the effect of planting dates in autumn sowing 28/9/2013 = (1), 8/10/2013 = (2), 18/10/2013 = (3) and spring sowing 18/3/2014 = (1), 28 /3/2014 = (2), 8/4/2014 = (3) on yield and growth parameters. The results showed that the autumn sowing has a significant increase in growth parameters compared to spring sowing: adapting coefficient (76.67-82.28%), Plant hight (67.15 - 56.3 cm), number of branches/plant (11.63 - 6.84), number of head/Plant (21.39 - 17.76), oil content (23.19 - 20.68)%, yield petals (96.12 - 60.57) kg/ha, seed yield (1331.82 - 768.31) kg/ha, oil yields (315.15 - 158.99) kg/ha to autumn and spring, respectively. While maturity date of autumn plants was delayed compared to spring (245.33 - 145.33) Day. When sowing was of autumn, growth parameters of third soing date were a significantly higher compared to both the second and first sowing: number of branches / plant, number of heads / plant, number of seeds / head, oil ratio (%), oil yield (kg/ha), yields seeds ( kg/ha), petals yield (kg/ha). Wheras the first sowing date has delayed maturity date compared of both the second and third sowing dates. When sowing was in spring, growth parameters of the first sowing dates were a significantly higher compared to both the second and third except for days to maturity.
This search was carried out in the farm of faculty of Agriculture- Damascus during 2012-2013 to determine the adaption of five Safflower genotypes) Farming conditions in the lug intensive in the province of Damascus under the effect of different nitrogen fertilizers and witness without fertilization N3 . And how they affected safflower accessions morphological traits and productivity.
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.
