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 .

Concept which tackled the effect of international trade organization policies in agricultural exports in developing countries were various. These concepts remarked that organization policies had made a decrease in the share of developing agricultural export to its GDP. Thus, trade exchange rate has become unfavorable in developing countries and this had its effect in distributing the National income on both National and International levels. This increased the backwardness of developing countries and shared in the progress of advanced countries. There are also other ideas which say that international trade organization policies had got great advantages for the developing countries reflected in its agricultural exports depended upon this conclusion that the principles of the classic theory in foreign trade which mentioned by the economist David Ricardo in writing the political economy of 1817. in this respect, the study depended on a hypothesis which says that international trade organization policies have variant effects in agricultural experts in developing countries according to the nature of its economic structures and the efficiency of its systems in dealing with the organization policies . In order to confirm the papers hypothesis, a sample of developing countries had been chosen included (Egypt, Moritania, Tunisia, Turkey, Thailand, Indonesia, Morocco, and Jordan). This sample depended on time series data in estimating the phenomenon of the study and for each country separately for it reflects the resulted changes in its agricultural exports in view of features and characteristics which differ from one state to another.

الخلاصة

A strain of Lactobacillus brevis was isolated from a spoiled pickle sample and propagated in MRS liquid medium. The strain possessed high mannitol dehydrogenase activity. The free and immobilized cells in calcium alginate gel beads were used for the production of mannitol using batch culture in bioconversion medium (BCM). The highest mannitol yield was achieved after four days of incubation at 37 oC using cells concentration of 2x106 cells/ml. The reuse of the cells for mannitol production led to a little decrease in their produtibility. The effect was minor with immobilized cells. Mannitol production was proportional to fructose concentration in BCM medium while there was no effect upon using potassium phosphate buffer medium. The continuous mannitol production by immobilized cells was conducted in a glass column. A reverse relationship was noticed between fructose solution flow rate and mannitol yield, but the production rate was higher at higher flow rates. Thus, it is advised to apply fast flow rate with repeated substrate recycling in order to achieve the desired conversion of fructose.

This study was conducted to test the ability of the lesser grain borer to attack 10 varieties of wheat and caused any injury to the grain stored in their ears, and to compare that with the infestation of the released seeds of the same varieties. The results showed that the beetle failed to cause any damage to the first group of wheat, although the process of re-infection were repeated three times, and that the incidence of the insect for all varieties of wheat stored in the ears was zero % , and that all insects were dead within a maximum of 10 days after putting them on the ears, while the percentage of germination of the stored grains reached 75.2% as an average.,while it was decreased for with an average of 32.3 %. It also resulted in injury insect to a significant decrease and clear the proportion of gluten in the flour of infected seeds with an average of 19.9 % as compared with that stored in the ears showing an average of 35.2% . On the other hand the percentage of infection for the released seeds reached 52.3 % as an average., as confirmed by the amylograph test the existence of significant differences between the values of the maximum viscosity were very high in the infected samples giving an average of 901 B.U while it was in the sound 548.4 B.U.,such differences for some of the sensory qualities of grain exposed to insect injury made it unacceptable from the standpoint of work manufacturing laboratory bread or some other pastry.

This study was carried out in the field of College of Agriculture - University of Salahaddin in Erbil during the season 2009 - 2010 including the evaluation of four hybrids derived from diallel crosses among seven varieties of durum wheat, previously assessed on the basis of combining ability and heterosis of them. The breeding program continued until these hybrids reached the sixth generation, and were compared with three other varieties, two of them cultivated on a large scale. Fifteen traits were studied, including different growth, physiological characters and grain yield and its components. The hybrid (Acsad- 65 × Kosem- N) has been selected to continue its breeding in order to adopt a new variety based on its performance superior in most of the studied traits, especially in the productivity score and grain yield and in traits that are showed positive correlation with the grain yield like leaf area index, net assimilation rate, spike length, 1000-grain weight and spikes/m2, which had the greatest effect in the prediction of grain yield according to the results of multiple regression analysis.

The experiment was carried out at the field of College of Agriculture at the University of Duhok during the spring season of 2010. Eleven inbred lines of maize, had been selected, eight of them were used as a line (males), (ZP 204, ZP 301, ZP 595, ZP 670, ZP 430, ZP 505, un 44652, ZP 735) and the reminder used as testers (females), (ZP 197, ZP 607 and ZP 707) to estimate gene action, specific and general combining ability, heterosis and heritability for yield and its components under two nitrogen fertilizer levels (135 and 275 Kg N/ha). The results showed significant positive heterosis for most studied characters of hybrids under two nitrogen levels. The better hybrids for grain yield were (ZP 607 × ZP 505) and (ZP 707 × ZP 204). The line ZP 505 showed the heights positive GCA effect of grain yield. Heritability in broad sense was high for all studied characters while heritability in narrow sense was high for ear height under both nitrogen levels and number of rows / ear under value nitrogen level only. The additive variance was more than dominance variance for all characters except 100 grain weight (g) and ear length (cm) under (135 Kg N). The average degree of dominance was greater than one for all characters. The results of this study can enhance the use of promising inbred lines in a programme focused on developing hybrid that efficiently can take up and use nitrogen.

A full diallel was established in 2006 at Duhok Univ., Iraq, to study heterosis and combining ability for growth, and yield components in four varieties, Early long purple(1),Long purple(2),Black Beauty(3), and Alton kubry (4) of eggplant. The results revealed that F1's exhibited significant heterosis for all traits. The hybrid (3×1) gave the highest heterosis value for plant height and fruit weight. The hybrid (4×2) produced the greatest value for number of branches and early yield plant . Whereas, the hybrid (4×1) was earliest in date of flowering and possessed the highest heterosis in fruit diameter. The parent 2 (long purple) revealed as the best general combiner for most desirable traits . Analysis of combining ability indicated that GCA mean square was significant for all traits, whereas, SCA mean square was non-significant in number of branches ,number of leaves till 1st inflorescence, total and early yield. Specific combining ability results for each hybrid exhibited that 2x4 was characterized with a good specific combining ability for most traits .On the other hand ,there was a significant reciprocal effect's for date of flowering, no. of flowers inflorescence-1 , average fruit weight, no. of fruits plant-1 ,fruit length and diameter which was obviously recognized between the hybrid 3x1 and its reciprocal.
