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

Invertase from Saccharomyces cerevisiae was immobilized by entrapment in carrageenan gel beads and used for sucrose hydrolysis. The immobilization efficiency was 88% when the concentration of the added enzyme was 100 unit/ml of gel and dropped to 49% upon increasing the added enzyme concentration to 500 U/ml. The immobilized enzyme remained fully active after 12 weeks of storage at 4°C. The hydrolytic activity of the enzyme was found to be influenced by temperature and pH. The preferred hydrolysis temperature was 55 °C for both the free and immobilized forms. The optimum pH was 4.5 for the free enzyme and was 4.5 – 5.5 for the immobilized enzyme. Km values for the free and immobilized invertase were 63.4 and 87.8 mM, respectively. Vmax values for free and immobilized invertase were calculated as 31.4 and 24 mM.min-1, respectively indicating lower affinity by the immobilized enzyme for its substrate and lower reaction velocity. In a continuous process using packed bed column, hydrolysis percentages of 84, 29 and 18% were obtained by using flow rates of 0.25, 1 and 2 bv/hr, respectively. On the contrary, the specific productivity was enhanced by increasing the flow rate in the column.

This study was carried out in a private nursery in Mosul city, between February and September 2004, to investigate the effect of shading percentage, GA3 and micronutrient on chemical composition of Indian rubber plant Ficus elastica Roxb. decora plants produced by vegetative propagation. Hence, three different factors were investigated: shading at 35 and 70% from natural light, spraying with gibberellic acid (GA3) at 0, 100, 200 and 300 mg/ Liter were applied every 21 days, two times as foliar spray, and micronutrient at 0, 1 and 2 dosage/ week/ pot. The Factorial Experiment was conducted by using the Split-plot in Randomized Complete Block Design. Each treatment was replicated three times. The results can be summarized as follows: The shading percentage had no effect on all chemical characters studied except Fe content. Spraying with 300 mg GA3/ Liter gave a significant increase in total chlorophyll, total N % and the content of Zn, Cu and Mn when compared with the control plants, but these treatments caused a significant decrease in Fe content in leaf tissue, while carbohydrate content did not affect. Fertilization with micronutrient increased the content of anthocyanine, Zn and Cu increased to 7.19 mg/ 100g fresh weight, 79.06 mg/ kg, 14.32 mg/ kg, respectively when adding 2 dosages of micronutrient/ week/ pot compared with 6.31 mg/ 100 gm fresh weight, 71.38 mg/ kg and 10.59 mg/ kg for control respectively. In general, the interaction between 35% shading, spray with 300 mg GA3/ Liter and one dosage of micronutrient gave best results of N% and CHO%, but the best results of total chlorophyll and Anthocyanine content were in 2 dosage micronutrient/ week. Finally, higher values of Zn, Cu and Mn content were under the interaction 70% shading, 200 mg GA3 / Liter and 2 dosage of micronutrient.

The current work was carried out on fifteen multi-coloured male local rabbits aged 4-6 weeks old. The rabbits were allocated into three groups having a resembling mean live weights. The 1st group was fed a control ration composed of concentrated feed and fresh Lucerne (alfalfa) plants. The amount of lucerne used was represented by a quarter of the matter of the concentrated feed daily offered to the rabbits. The 2nd and the 3rd groups were fed conc. Feed as well as fresh celery and cabbage leaves for the other two groups, respectively. Throughout the feeding trial which lasted eight weeks total body gain and daily consumed feed were calculated. At the termination of the experiment, all rabbits were sacrificed and carcass measurements were taken. The findings showed that there was a significant difference (P≤0.05). between the 1st group as compared with the 2nd and 3rd groups in relation to total body weight. Also the results revealed that total concentrated feed a mount consumed was different among the three groups, with nearly similar feed conversion efficiency of all groups. There were a significant differences among the groups regarding mean hot carcass weights characters as well as fleshing percentages, considering dressing percentages and edible organ weights, there were no significant differences among the three groups. From the above results, It is advised not to add fresh celery or cabbage leaves alone to the concentrated rations of the local growing rabbits as a sole source of roughages because it may adversely affect their productive traits. therefore owing to the low crude fiber contents of celery and cabbage leaves, it is recommended to be mixed with other suitable roughages.

Brucella melitensis was isolated from human which is the final host for this bacteria and from sheep milk, the main sourse of infection. Two isolates were obtained; isolate (1) from 23 blood speciemens taken from patients showed clinical findings of malta fever which their serum gave high agglutination titer in Rose Bengal Test, isolate (2) was isolated from 37 milk sample collected from (Mahweer, Manarat Shabbak and Bartillah) from sheep which suffered from abortion and their serum gave positive results with Rose Bengal Test. After the diagnostic biochemical tests, we found that these two isolates belonged to the species B. melitensis. Both isolates were cured in soft white cheese when flooded in a salt solution at concentrations 5 and 7.5 % and stored at 4 oC. No growth of isolate (1) was observed after 13, 11 days respectively, also no growth of isolate (2) was observed after 17, 13 days when flooded with a salt solution at concentrations 5 , 7.5 %, respectively , but there was no effect of the concentration 2.5 % on the resistant of both isolates in cheese. Both isolates were cured from soft white cheese when exposed to 50 oC for 60 minutes and 60 oC for 30 minutes. The study showed that the combination use of flooding with salt solution and high temperature in results treatment of both isolates in cheese has given an inhibitory effect on both isolates resistance in a short time when compared with the use of each factor alone. The concentration 2.5 % showed an effect on both isolates in cheese when combined with the temperature factor. The use of 50 oC with flooding with salt concentrations 2.5 , 5 , 7.5 % led to cure both isolates after 20 , 20, 10 minutes, respectively , and when 60 oC was used with the same concentrations above also led to cure both isolates at 10 , 10 , 5 minutes respectively.

Five entries of durum Wheat (1- Azul-5 2- Yousef-1 3- Omgenil-3 4- Syrian-4 5- Mrb3/mna-1) in addition to local cultivar (Um-Rabeeh) and their hybrids were used. The studied characters were number of days to 50% flowering, plant height, number of grains/spike, number of spikes/m2 , biological yield , grain yield, harvest index, 1000-grain weight and protein percentage. Entries were significantly different at 1% level for all traits. Phenotypic and genetic coefficient variation vounes were low for numbers of days to 50% flowering , number of spikes/plant , grain yield and protein percentage , medium for plant height , number of grains/spike, biological yield and harvest index and high for 1000-grain weight . Expected genetic advance values were low for number of days to 50% flowering, 1000-grain weight and protein percentage, high for grain yield and medium for the other traits . The cross (Syrian-4 × Azul-5) exhibited significant heterosis in desirable direction for plant height, biological yield and grain yield , while the cross (Um - Rabeeh×Yousef-1) had significant and positive heterosis for protein percentage .
