حول المجلة

صدرت مجلة زراعة الرافدين لأول مرة عام 1966 واستمرت لغاية عام 1982، وتوقفت بعد ذلك لمدة ثلاث سنوات بسبب القرار الوزاري بتوزيع المجلات العلمية على الجامعات العراقية وحسب الاختصاصات حيث كانت حصة العلوم الزراعية لجامعة صلاح الدين التي أصدرت المجلة العراقية للعلوم الزراعية (زانكو)، وكانت المجلة الوحيدة في العلوم الزراعية في وزارة التعليم العالي والبحث العلمي ، ثم صدرت مجلة زراعة الرافدين مرة أخرى وذلك في عام 1986 واستمرت إلى عام 2000 إذ تم اعتماد مجلة زراعة الرافدين مجلة قطرية وبهذا تم تغير اسمها إلى المجلة العراقية للعلوم الزراعية . وحصلت على الرقم الدولي ISSN 1609-4077 واستمرت بالصدور إلى المجلة إلى عام 2004 إذ تم إعادة اسم المجلة إلى مجلة زراعة الرافدين واعتبرت مجلة قطرية – دورية-علمية – محكمة وحصلت على الرقم الدولي الجديد ISSN 1815-316X وصدر المجلد 33 العدد 1 وهو تسلسل مجلة زراعة الرافدين إذ أن المجلة أصدرت 32 مجلد قبل تحويلها إلى المجلة العراقية للعلوم الزراعية. واستمرت المجلة في الصدور إلى الوقت الحاضر 2012 المجلد (40) .

كانت المجلة عند صدورها عام 1966 بعدد واحد سنوياً، وحالياً تصدر بأربعة أعداد دورية لكل سنة. ولابد من الإشارة إلى أن المجلة في بداية إصدارها عام 1966 كان يضم العدد خمسة بحوث باللغة الانكليزية، وتزايدت في الوقت الحاضر لتضم 30 بحثاً باللغتين العربية والانكليزية .

حصلت المجلة خلال مدة عملها على تقييمات وزارية عالية فقد حصلت هيئة التحرير في عام 1996 على كتاب شكر وتقدير من السيد الوزير لتميز المجلة ، كما اعتبرت المجلة متميزة في عام 2009 أيضا إذ حصلت على درع الوزارة وشهادة تقديرية .وقد حصلت المجلة في سنة 2012 على الاعتمادية الدولية وبالتالي اصبحت في متناول جميع دول العالم .

There is a growing public interest in sustainability and environmental conservation. This growing public concern implies the need for focusing programs on sustainable agriculture, where by, agriscience college teachers, and extension agents can play a key role.. However, the question is whether agriscience teachers, and extension agents have been prepared to carry out this task? The focus of this study was to identeify agriscience teachers', and extension agents' perceptions regarding sustainable agricultural practices. This study used survey design and was conducted on 68 agriscience teachers and 112 extension agents in Ninavah. An instrument was developed to collect data consisted of two parts utilized to identify their perceptions regarding importance and impacts of sustainable agrecultural practices. The form also consisted of two questions, one about the importance of diffusion of sustainable agriculture concepts among agriscience teachers, extension agents, and farmers, and the other about their perceptions regarding importance of including agricultural education programs a subject on sustainable agriculture. The results showed that both agriscience teachers and extension agents perceived importance and impacts of sustainable agricultural practices.However agriscience teachers were more positive toward instruments items than extension agents. Both teachers and extension agents interested in diffusion of sustainable agricultural concepts among agriscience teachers, extension agents, and farmers, as well as they had apositive view towards including agricultural education programs a subject about sustainable agriculture in agricultural college, institutes, and schools.

This experiment was carried out during the growing season of 2004 – 2005 at Horticulture field researches, Agriculture and Forestry College, Mosul University to evaluate five faba bean cultivars for water stress and supplementary irrigations by withholding complementary watering at either vegetative (RWW), flowering (WRW), pod developments and seed fillings (WWR) stage, whereas the check and other treatments were watered whenever 25% soil AWC is depleted to a depth of 25 cm. The results revealed that Pod developments and seed fillings was the most drought susceptible stage where supplementary irrigation should be applied to improve yield and yield quality. However, other stages were less sensitive, particularly the early vegetative stage. The five cultivars were categorized in the following order according to their performance at the most drought susceptible stage: Local Syrian > Aquadulce > Towaytha > Babylon > Taka357. Subsequently, forecasting depending up on cultivar seeds germinations under sub-optimal conditions could not be used as indicator for the approval of drought resistance cultivars. Finally, results confirmed the Taka357 was the most drought susceptible during all stages particularly in seed filling stage.

This study was designed to determine the ability of hydrogen peroxide (0.5 %) consumed in drinking water to induce oxidative stress in lying hens and to make sure of oxidative stress interference occurred in creating fatty liver hemorrhagic syndrome (FLHS) in this pattern. Oxidative stress was determined through measuring the levels of glutathione (GSH) and malondialdehyde (MDA) in liver tissue and of Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) aspartate amino enzymes levels . H2O2 treatment showed significant increase in glucose , cholesterol and triglycerides levels and significant decrease in liver tissue glutathione GSH and asignificant increase in liver tissue malondialdehyde MDA . The levels serum AST and ALT were significantly increase also , the above changes indicate the ability of oxidative stress in laying hens . Methionine was used to determine its ability in preventing oxidative stress or to remove the effects of oxidative stress . The methionine was used as capsules given orally . Laying hens were divided into (5) groups . Each group included (7) birds were treated daily for (28) days . Methionine was chosen in order to test their ability to protect birds against oxidative stress or To remove the effect of oxidative stress as follow : 1- Treating the laying hens with methionine with out oxidative stress for 28 days . 2- Treating the laying hens with H2O2 together and methionine from beginning of treatment . 3- Stressing the laying hens from the beginning of treatment water with then treat it with methionine from the (15th) day of the beginning of H2O2 treatment . The treatment of methionine showed similar effects when it was used . It reduced the levels of glucose , cholesterol , triglycerides , ALT and AST in serum . Also the level of GSH increase whereas the level of MDA decreased , as well as decrease in the fat liver % . The results of this study were identical with the hypothesis that states : free radicals are considered strong causative factor in (FLHS) in laying hens so the H2O2 (0.5 %) induced oxidative stress in laying hens can be considered anew experimental pattern to be used in different scientific studies in order to create asimilar case of fatty liver hemorrhagic syndrome .

Codling moth is very common pest that infesting the apples in addition to pear and quince. Also produce high economic looses. The percentage of fallen fruits as a result of infestation was 60.34 %. Infestation by this pest also caused that the fruits to be not approached to the normal size and weight as well. The size of invaded fruits was 56.18 cm3, while that of the non-invaded was 71.68 cm3 in average. The average weight of infested fruits was 46.78 gr. and that of the non-infested was 59.98 gr. Chemical control of the pest was conducted using three concentrations of the pesticides: Actellic (1, 1.35 &1.6 cm3 / L.), Danitol (0.6, 0.9 & 1.2 cm3 / L), and Sumicidin (0.67, 0.95 & 1.2 cm3 / L) at the three peaks 20 April, 21 May & 1 July according to the threshold level. Results of control showed high activity for the three insecticides giving 0.77, 0.87 & 4.74 % as an average of infesting fruits respectively, while that of control was 77.59 %. It can be concluded that for successful control it must be precisely define the emergence of the pest using the light and food traps which considered being very important issue to demonstrate spray times for the chemical control.

الخلاصة

This study was conducted in College of Agriculture University of Mosul during 2004 to show the light color (blue, green, red and white) and light density (100, 160, 250 W) which was used in Hestand light trap on adult trapping of lepidoptera. The effect of color and density of light on adult of some specis of order lepidoptera cutworm attractively was studied, the result showed that the traps with blue color bulb were more effective than of green, red & white color where the average of captivity were the 2.80, 1.93, 0.67 & 0.93 adult night, respectively. The study also showed that there were no significant differences between the traps of the white light density of with 160W bulb power and 250W bulb power which gave average captivity of 7.17 & 7.43 adult night, respectively, while traps of 100W bulb showed lower effect in adult capture.
