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 .

الخلاصة

Wheat production under climate of northern Iraq depends mainly on annual rain quantity and its distribution. Generally the annual rate is low and poorly distributed ,as a result the yield is low and unstable. Accordingly it has been suggested that small amounts of supplementary irrigation (SI) can alleviate the adverse effects of such unfavorable rain pattern, moreover the optimum dose of nitrogen fertilization is an important factor boosting wheat production and improving quality. The purpose of this study was to investigate the effect of nitrogen fertilizer and abridged (SI) on yield and grain quality. Field experiments were performed during the growing season 2003-2004 at two locations laying out as split-split plot design in RCBD, involving four promising bread cultivars as sub-sub plot, two levels of N fertilizer (zero and 80 kg N/ha) as sub-plot under rainfall alone and with (SI) as a main plot added at booting and heading stages at a rate of 25 mm for each stage. The results showed that N fertilizer had a significant effect on grain yield, grain protein content at both locations. The (SI) affected significantly number of grain/spike, grain yield, the interactions between factors were significant for most characters.

The study tackles the effect of agricultural investment in developing the agricultural sector in iraq for the period 1880-2000.analysis has been made by the minimum square method in two stages (2.s.l.s). Linear function has been chosen as the best means for the equation in accordance with economic aspects representing the correlation between agricultural investment being a variance and the limited factors being independent variances. They are agricultural loons to form the fixed agricultural capital, G. D. P., trade balance, chemical technology, mechanical technology, agricultural work force, agricultural domestic product. It is clear from analysis the significance of all variances (forming fixed capital, trade balance, mechanical technology, agricultural domestic product).as for the second stage of estimation, values of agricultural investment have been used being a variance and the agricultural growth being a variance dependent upon the decided function. There is also a negative correlation between the agricultural product growth and the agricultural investment. This correlation shows the negative reflections of both war and blockade as well as concentrating investment expenditure upon projects of infrastructure and reconstruction neglecting protects of agricultural product, all this has led to the weakness of agricultural investment and in consequence the weakness of the agricultural product growth.

Rain agriculture of cereal crops is submitted on a high level of risk and uncertainty especially in the relative importance of agricultural areas which depend upon such a type of irrigation. Acreage productivity undo rain production conditions is full of risks due to the difference of rain full and its distribution. Therefore, the research tries to measure the type of the relation between Barely and Wheat crops production from one side and the level of rain fall through the stages of plant growth from another for the period 1980-2000 in Nineveh province. This quantity limit has its own importance directly upon food product and Iraqi food security. Depending upon the hypothesis which says that there is a strong relation between the ratios of rainfall and the productivity of both Wheat and Barely. There is also another strong relation between rain distribution upon the main stages of plant growth and the productivity of acreage for both crops .Econometric and analytical results have confirmed that there is a significant relation between rainfall and the productivity of both Wheat and Barely crops as a dependent variance. Also, there is a variation in relative importance for the relation between dependent variance and the distributional nature of rains during the stages of plant growth for the two crops of the study.

This study was put to investigate the possibility of utilizing E. camaldulensis bark extract as an adhesive for particleboards manufacturing after the determination of their tannins content. Bark extracts were extracted by using either hot water or 1% Na2CO3 (both gave an acceptable percent of extracted tannin). Prior to panels manufacturing, the concentrated extracts were hydroxymethylated with para-formaldehyde which normally releases formaldehyde during hot pressing. Panels were manufactured using either hydroxymethylated hot water extract or hydroxymethylated Na2CO3 extract, all at three levels of pressing temperature (160, 175, 190 c◦.) and two levels of pressing time (10 and 15 minute). A 10% resin content was used to get a panels target density of 0.55 gm/cm3. The physical and mechanical properties of the produced panels were tested. The results indicated, that by using hot water hydroxymethylated extract, a better values of the different studied properties were obtained, especially with those panels which manufactured at 175c◦.press temperature and 15 minute pressing time, but in general the average values of such panels did not exceed the values of the same properties given in the American standard for particleboards properties.

Survey of eggplant fields showed that 93.33% of the fields were infected with root– knot nematodes , the mean of the infection was 33.33% in these fields reaching it’s maximum value (51.66% ) in the fields of Salamia area while it’s minimum value was 16.66% in the fields of Mosul area . The highest population density of nematode was found in the soil of one of the fields of Rabee’a area and the lowest in another field in the same area . Distribution of root–knot nematode species in eggplant fieids showed the presence of M.javanica and M. incognita .The former one was more widespread . Susceptibility of eggplant cultivars against M. javanica revealed that the cultivars differed among themselves.The cultivar Alton Kopri was the most susceptibile one, while Black beauty was with medium resistance. M.javanica completed its lifecycle in the roots of cultivars Al-Ton Kobri, Asil Zakholi (local) and Syrian in 27,30 and 32 days respectively, while nematode could not complete its life cycle in the roots of Tarhi and Black beauty cultivers.
