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 .

Weed control study on cotton conducted during summer growing season 2005 at Sumel and Zakho (Dohuk Governorate) in Iraqi Kurdistan region, to determine the effect of different methods of weed control. Cultural practices used in different row spacing (60 or 80 cm) while mechanical methods used hoeing at 4, 8, 4+8 weeks after sowing (WAS). Also chemical herbicides such as Treflan pre-planting soil incorporated, Gallant super early post – emergence and Treflan+Gallant were used. Weeds can compete strongly with cotton, potentially reducing cotton yields .Decrease in row spacing (60 cm) was much better for reducing weed dry weight than 80cm within 75 or 100 days after sowing. On the other hand, the narrow spacing gave more cotton yield and increase up to 76.88 %, 40.81% at Sumel and Zakho locations respectively. Hoeing at an early stage or two times of hoeing was a good option for weed control. Also two times of hoeing 4+8 (WAS) was more effective on weed than row spacing. Lint yield was higher up to 408.75%, 173.55% in two times of hoeing treatment at the two locations, respectively. Treflan or Treflan+Gallant gave significant result in reducing weed biomass in both locations over two periods. However, Treflan+Gallant reduced weeds dry weights 42.8%, 41.8%, 70.6% and 71.5% at the two locations within the two periods, respectively.

ِAn evaluation of olive irrigation in Bashiqa area was done. Informations were collected for ten different orchards, which describe area of orchard, numbers and age of trees, and their average production. with the calculation of discharge applied to every one. Field measurements also were done to find depth of irrigation water in the year. This is compared with the calculated depth of irrigation water requirement by using CROPWAT software depending on average monthly climatological data and rainfall. The results show that the age of tree affect the productivity, also the applied irrigation water to these orchard are less than their requirements. So, it is recommended to increase the amount and frequency of irrigation water. A seasonal irrigation water depth of 400-650 mm, with an average of 100 mm during summer months, is a good choice for better production.

The effect of carrot (Ca) juice on induction of chromosomal aberrations in white mice bone marrow cells was studied under natural conditions and induction of cyclophosphamide (Cp). Results showed that administration of juice (0.1, 0.25, 0.5)ml orally for 6 days had no effect on induction of chromosomal aberrations(Chromosomal breaks, Chromatid breaks, Ring chromosome and Dicentric chromosome), except that the higher dose (0.5 ml) elevated the level of chromosomal aberrations slightly and it was beyond the statistical significancy (P< 0.01). While oral administration of Cp (50 mg/Kg of animal body weight) increased the aberrations 9 times in comparison to the negative control , the latter level of aberrations was lower to 7 times due to natural defense processes of the body. Using the juice and mutagens in different combinations, such as using juice after administration of the mutagen (Cp/Ca), or using the juice before administration of mutagen (Ca/Cp) or administration both of them together resulted in lowering the aberrations in general, but the treatment of (Ca/Cp) was the best especially when used for 6 days.

This system was used to study the mutagenic effect of rocket juice (Eruca sativa) and its antimutagenic activity against the cyclophosphamide(Cp) mutagenic activity using different combinations by measuring the cytotoxicity (Estimating the survival index) , and genotoxicity by estimating the induction of streptomycin and rifampicin resistant mutants (As chromosomal markers) . Results showed that rocket juice at 50 and 100 µl / ml of log culture cell suspension in phosphate buffer had no cytotoxic or genotoxic effects , higher levels (200µg / ml) had slight cytotoxic and genotoxic activities . Cp had both cytotoxic and genotoxic activities . Combinations of plant juice and mutagen (Cp) together (J+Cp) or using juice before treating with mutagen (J/Cp) or using the juice after treatment with mutagen (Cp/J) showed different effects . The treatment (J+Cp) and (J/Cp)protect the cells and the survival index didn't exceed the cutoff value of mutagenic agents , while the (Cp/J) treatment was unable to protect the cells . The latter effects appeared as an induction of streptomycin and rifampicin resistance .

This work was put to determine the best value of specific gravity of Poplar nigra through different sampling criteria. Four groups of seven years old poplar trees were used (3, 5, 7 and 12 trees). Samples were taken at different heights from the stem of each tree(at :stump height , Breast height , at each one meter and two meters along the stem )in addition other samples were taken from fixed position (at: Breast height ,1/2 and 2/3 the height of tree) to determine the specific gravity . The results showed , a significant variation among the groups of trees and throughout the stem height .It is found that the groups of 3 and 5 trees gave values of specific gravity not representative to the actual values ,The same is true for the average values at breast height and for the three levels of height in the stem ,because it appeared that the first gave average value was lower and the second level gave higher average than the actual value of the specific gravity of poplar trees, while the average values at stump height in the group of 12 trees gave a considerable value which is close enough to the actual value ,and one can use it as a representative value of the specific gravity of Poplar nigra.

A half diallel analysis among five inbred lines of maize (OH40, N28, W17.161, B57 and Agr183) was done. Inbred lines and crosses were planted using randomized complete block design with three replications. Data were taken for traits: plant height, upper ear height, number of ears per plant, length and diameter of ear, number of rows per ear, number of grains per ear, 100 grain weight and grain yield per plant. The results showed that mean squares of genotypes, general and specific combining abilities were significant for all traits. Marked significant heterosis was observed for almost all the traits studied. It was shown that dominant variance was more than additive one for all traits except number of grains per ear. The two inbred lines OH40 and B57 were good general combiners for the most traits, and the crosses (N28 x OH40) and (B57 x N28) were the best specific combinors. Broad sense heritability was high for all the traits while narrow sense was high for number of grains per ear. The genetic advance as percent of the mean was moderate for number of grains per ear and low for the remainder traits. Average degree of dominance exceeded one for all the studied traits, and this an indication of the presence of over dominance.

This study was carried out at two sites of different texture which was clay and a clay loam in Mosul - Al-Rasheedia. and located at what is considered to be a semi water fall guaranteed arable area .A plough of three different shank shapes have been used . These shapes were vertical, inclined forward and curved with two plough depth of 8-12 cms and 13-17 cms successively with three speeds 3.70 ., 7.15 and 9.64 Km/hour. To study the effect of the shank shape on the some physical properties of soil (moisture content, bulkdnsity, porosity, penetration resistence and mean weight diameter) the two experimental farms have been designed by the use of complete randomize design which was used with three factors and replications. The main results of this study are: The curved shank outperformed at the first site and at the three dates in recording the lowest bulk density, highest porosity and the lowest penetration resistance for the two dates at the first site and by the use of the means of the two sites. The 8-12 cm depth outperformed at the two sites with their means in recording the lowest bulk density and highest porosity .The (7.15) Km/ hour speed recorded the lowest bulk density and highest porosity at the beginning , middle and the end of the season. The vertical shank at depth of (13-17) cm and at speed of (9.64) Km/hour gave the highest moisture content at the first site at the end of the season. The inclined forward shank outperformed at the depth of (13-17) cm with speed of (7.15) Km/hour at the second site giving the lowest bulk density and highest porosity at the end of the season.

The study showed a negative correlation among soil – saprobs Aspergillus nigur , A. flavus, A. ochraceus , Mucor sp. , Penicillium glabrum , Stemphylium loti and Fusarium oxysporum f. sp. radicis – lycopersici (Forl) , i . e. ,a significant reduction in its inoculum density , with aprominance of A . nigur and A. flavus. Regression analysis exhibited that excess of Diammonium phosphate and of Forl inoculum resulted in reduction of its pathogenicity . Manures were increased each of saprobs and the pathogen.Thus , Manures as soil amendments stimulated saprophytic competition in the soil and also inhibited the growth and sporulation of Forl , particularly A. niger. The application of Diammonium phosphate plus mixed saprophytes and Forl inoculum decreased disease incidence insignificantly in the greenhouse, the use of manures also reduced disease severity. Soil humidity increase by 1% resulted in increase of severity by 0.02.
