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 .

Four varieties of broad bean (French, Syrian, Tewwtha and Babylon) were used in a complete diallel cross.Genotypes(parents and F1 hybrids) were sowing in college of agriculture and forestry fields at Hammam Al-Alil using randomized complete block design with three replications. The studied characters were plant height (cm), no. of days to heading and maturity, no. of branches per plant, leaf aera index , no. of stem nods ,no. of florets, pod setting ,pod length, no. of pods per plant, no of seeds per pod, 100 seed weight (gm) , seed yield (gm/ plant) and biological yield. The parents and F1’S were significantly different for all studied characters except heading date. General combining ability was significant for heading and maturity date, no. of branches , no. of node, leaf area index, pod length, no. of seeds per pod and seed yield, while specific combining ability was significant for all studied characters except no. of node , no. of florets and pod setting . Reciprocal effects exhibited significant differences for all characters except for heading date. A significant additive variance were found for all studied characters except 100 seed weight, while a significant dominance variance was detected for all characters except heading date, pod length, pod setting and no. of pods per plant . Broad sense heritability (H2) estimates were high for maturity date, leaf area index, no. of seeds per pod ,100 seed weight and seed yield, while narrow sense heritability (h2) estimates were low for all characters except maturity date, leaf area index, no. of pods ,pod length , no. of pods per plant and no. of seeds per pod.

Data were collected for yield, its components, protein and oil percent. The analysis carried out according to the factorial mating design method of to study the combining ability and gene action. The results showed highly significant differences among genotypes for all studied characters.The line SH appear to have good general combining ability for larger number of characters followed by IK8 and ZP. The crosses showed differences in its specific combining ability effects. The crosses (ZP x W13R) and (OH40 x W17.161) have specific combining ability effects in desirable direction for most characters. The dominance genetic variance was more important than the additive variance for the most studied characters, and the estimates of average degree of dominance was greater than one for all characters. Broad sense heritability ranged from 86.77% for ear diameter to 99.62% for 100 grain weight, while narrow sense heritability ranged from 20.92% for protein percent to 61.40% for number of rows per ear.

A field test was conducted during the season of 2004-2005 at kileasan Research Center in Agriculture college- Sulaimani University, to study the influence of varieties(Nainava, American selected), cultural methods(row, sowing) and three seed rates (15, 25 and 35 kg/D) on the lentil growth, yield and its associated weeds. RCBD with three replicate was laid out in factorial experiment. The results indicated that Nainava variety was found to be superior when compared with American selected variety for the characters of pod weight, 1000 seed weight, seed weight/plant, seed yield/m2, but there was no significant difference between the two varieties for the other characters. Row cultural method posses higher and significant value than sowing method for total weed dry weight/m2, plant height, lowest pod height and empty pod no./plant, although an inverse result was recorded for plant dry weight and seed yield/m2. Among the seed rate, the high rate was surpassed the low one in total weed dry weight/m2, lowest pod height, 1000 seed weight and seed yield/m2. A significant interaction between the varieties and cultural methods especially at Nainava culturing by sowing was shown, also a significant interaction was observed between the varieties and different seed rate in one side & between cultural methods and seed rate in other side which revealed linearly increasing of seed yield by increasing seed rate. Simple correlation coefficient data confirm significant correlation between the characters.
