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 .

This study was conducted on poplar bud psyllid in Ninevah during the years 2004 and 2005. For the first time Egeirotrioza justa Burk & Laute has been studied and recorded in Iraq. The poplar bud psyllid Egeirotrioza justa Burck & Laute attacks Populous euphratica trees and as a result of feeding by newly nymphs, small galls are formed on the twig tissues near the buds. The adults appeared on the trees during May to July. Mating usually occurred during the first week of May, mean periods of pre – oviposition, oviposition and post – oviposition (1.8 ± 0.74, 5.30 ± 0.57,and 2.00 ± 0.49) days, respectively. Egg laying took place singly on the leaf petiols, and on bouth services and margins of mature as well as the tender young leaves and twigs. The average number of eggs laid per female was 21.80, hatching of eggs was 80%, and sex ratio was 1:2. This species hibernates as a second nymphal instar. This insect has one generation per year.The study indicated that the south direction of a tree from south side of the forest and at a height more than 3m for trees were represented high average number of eggs nymphs and adults (100.00, 64.48,and 57.40), respectively.

Endogenous concentrations of free and bound abscisic acid (ABA) in bitter almond seeds Badam variety (local variety) from Sulaimania orchards Prunus amygdalus L. were determined by TLC and HPLC during various periods of cold stratification (0,15,30,45, and 60 days) and the germination was investigated at the Plant Hormones Laboratory in the Department of Plant Production, Faculty of Agriculture, University of Jordan, Amman, Jordan, during the period 2004 to 2005. The results indicated that cold stratification (at 5 ºC using perforated polyethylene bags filled with moistened perlite) significantly reduced abscisic acid (ABA) contents of the seeds and their endocarps. A sharp significantly decline in ABA was observed during the first 15 days, especially in 45 days, after that the decline was completely decreased. The reduction in the level of ABA during stratification was associated with significantly increased germination percentage especially for 45 days (85.133 %).

Thirty five Awassi lambs of 5.5–6 months old, with average initial body weight 34.25 kg were divided randomly into five groups each of 7 lambs. All lambs groups were fed ad libitum for 70 days on one of the five rations. The first group (A) was fed on barley grain only, group (B) barley grain with 10% sun flower meal and 0.7% urea, group (C) barley grain with 10% vetch seeds, group (D) barley grain with 20% vetch seeds and finally group (E) barley grain with 30% vetch seeds in addition to limestone and salt. After 4 weeks four lambs were randomly chosen from each group for digestibility trials to study the effects of treatments on nutrients digestibility. At the end of the experiment three lambs from each group were randomly chosen and slaughtered to study the carcass characteristics. Daily food intake for the five groups were similar and there was no significant differences in the digestibility of DM, CP, ether extract and CF. whereas the group that took 30% vetch seeds had a significantly higher NFE digestibility compared with group A. calculated increases were observed in feed conversion efficiency, average daily gain, final weight, carcass weight, dressing percentage, rib eye area and fat thickness for group (E).

This study was conducted in the animal husbandry station Al-Rashidiya, a branch of the general enterprise of animal researches in Mosul Governorate. Twenty one single female lambs at weaning age 90 days were divided randomly into three groups, fed on three rations different in protein levels 12, 15 and 18%. The rations was offered restricted feeding at a rate of 1 kg/head/day until the age of puberty. Weight of female lambs were recorded monthly after weaning age up to age of nine months. Blood samples were collected monthly at age of six months from Jugular vein to determine the concentrations of FSH hormone. All the female lambs were subjected to the rams at age of 7 months to determine the age and weight of early breeding. The results indicated that protein levels had no significant effect on the age and weight of lambs at puberty. The female lambs which were fed 12% ration reached the age of puberty at 242 days and were faster than other lambs which fed 15 and 18% rations. However, lambs fed on 18% protein reached the age of puberty at weight of 41.30kg when compared with other lambs fed other level of protein and were 42.88 and 44.83 kg, respectively. Protein levels had a significant ( < 0.05) effect on the concentration of F S H at age of 7 and 9 months only. However, only 15 female lambs were successfully breed.

This Study was carried out on the Ceratonia siliqua seeds in its natural distribution regions in Syria. These seeds were treated with some mechanical (scarification), chemical (H2SO4) treatments and Hot water. The results showed that there are high differences between most treatments in all the study areas according to the period germination and the weight of seedlings. It was found that the seeds of Beit-salhab and Al-muhawata then Al-isawia and Ras-albasit's seeds gave better results than the seeds of Harem and Mardash under affect of scarification and H2SO4 treatments according to the period germination and the weight of seedlings, so we should engorge these seeds propagation to give the best nursling and good quality of fruits. Due to the fact that Ceratonia siliqua is a Multi-purposes tree, and according to the results obtained, it was suggested that it’s necessary to put a plan for the conservation of the Carob tree in its natural distribution regions, choose the best ways to propagate it and enforce its economic and environmental role by using it in the afforestation plans.

And two tables for Canadian Economy were put using input-output model for the Employment and compensation in forestry sector and wood field. The results of welsh showed that these are an interrelationship of forestry with printing, publishing , petrolation, chemical products, furniture, electrical power, machine sales, hotels and recreation. And also welfare that the total purchase was 13.4 million dollars from UK and 3.6 million dollar from other countries, also the results declare the size of the whole- consumption, taxes , labor cost and the total surplus of employees. In addition to the interrelationship of the production sector and the other economic sectors. Concerning the results of Canada, which show the size of employment in forestry and wood sector, the cost of employments in forestry sector for both male and female, reached 2934 million dollars and in the Agro forestry actives was 7.5 million dollar, it was distributed to ages of forestry and the proposed activities in Agro forestry. This study gives also the tables of final consumption of wood products with coefficient matrix of input- output tables which illustrates the contribution of economic actives such as wood production import and export in the consumption of wood products, The total consumption of industrial wood, lumbers, composition boards, pulp and papers and paperboard, appeared to be: 199.9 , 21.7, 5.9 , 71.7 and 26 million dollar respectively.

The more the insect numbers increased; the more the damage area and percentage were, and have reached 3.10, 3.52, 4.5Cm3 and 67, 16, 91, 17, 20.08% for Zafarnia, Othmani, and Le-Cont varieties respectively when the insects average number was 7, 13.5, 17.5 insectleaf for the varieties at temperature average of 27.96C and relative humidity of 51.5%, whilst damage area and percentage have reached in the 1st of August 7.7, 8, 11.52 for the damage area respectively and 15, 34, 89, 33, 40.67% for damage percentage respectively; at temperature average of 27.16C and relative humidity of 35.5%. A decrease in the insects average number to 2.25, 4, 9.75 insectleaf for the Zafarnia, Othmani, and Le-Cont pear varieties has resulted in a damage area and percentage of 0.39, 0.78, 2.62Cm2 and 2.16, 4.06, 10.83% respectively at temperature average of 10.08C relative humidity of 75.81%. The results also revealed a significant and positive correlation between insect number and temperature and the damage average area and percentage while the correlation with relative humidity was significant and negative for the varieties under discussion.
