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 .

The study aimed to recognize cultivators motivations to participate in the National Program For Cotton Cultivation Development, and to determine the reasons for non-participation in the program. The two research samples consist of cultivators who participated and those who did not participated in the Program, the first sample consists of 70 cultivators and the second sample consists of 88 cultivators. Two questionnaires we prepared, The first was prepared to measure motives of cultivators to participate in the Program while the second was prepared to determine the reasons for non-participating in the Program. The data was analyzed by using means and percentage. The results showed that the motivations of 78% of the repondents were weak to moderate, and that the economic motives occupied the first rank order, and the main reasons for non-participating were economic reasons. Though, we recommend to reinforce the cultivators by introducing financial support through the government and provide agricultural inputs with reasonable prices.

The study included both descriptive and quantitive analysis for the reality of production and consumption for the wheat crop in Iraq during the period 1980-2006 in addition to its future exceptions till the year 2015. Results of analysis have revealed that yearly increase in consumed quantities of wheat exceeds the yearly increase of produced quantities. This explains that the food gap is large and reached critical levels due to many factors like the high rates in population growth and the improved levels of income and the decrease of areas of land cultivated as well as the type of consumption from this crop. Therefore the imbalanced distribution of economic resources specialized for producing wheat crop. The gap started to become large during time and this needed to limit and estimate the most important factors which effect production increase to the level reaching the achieved increase of population in order to avoid the negative effects of food gap and to prevent this gap not to be expanded . The study reached that future expectation to produce wheat crop in increased slowly and dose not suit with the expected increases of population numbers. The study also ended with the necessity to encourage local investment in cultivating wheat and ton depend upon agricultural policies which share in elevating the largest amount of economic efficiency in producing wheat crop in Iraq.

Cotton's crop is considered to be one of the strategic crops in Iraq, it is an important sources for fibers which are used in textiles as will as using its seeds in vegetable oil industry. It is one of the important irrigated crops in Nineveh province. Due to the cost increase and decrease in production size and the remot production than the optimum size. these all affected the acre yield . thus,we tried to understand to what extent can the farmens achieve size economies through field data which included (30) farmers representing 8.57% from the contracted farmers with the national program to develop cottons agriculture for the season 2005 . It is clear from studying productive situation for the period (1988-2004) that there is an expansion in cultivated area production and productivity with the positive annual growth rate about (0.01,0.06,0.07) respectively .The statistical analysis for the applied example has shown that there is an opposite relationship between farms size and productivity and also the function of costs was cubic and the best size for production in long – run is 12.39ton . is for the optimum area it can be exploition it form cottons farmers is 25.52 acre . Therefore, it is necessary to use modern technologies in production which contribute in increasing the yield in order to fill apart of the country's need from this crop .

To study the effect of foliar application of boron on growth and yield of sugar beet, two representing locations to Nineveh province which are differ in their chemical and physical properties were selected. Four boron levels (0, 2.5, 5 and 7.5) mg B. L-1 were sprayed, as boric acid (17.5% boron), using complete randomized block design (CRBD) with four replicates, the addition of boron was applied once and after the plant have at least six leaves. The results indicated that foliar application of boron resulted in a considerable increase in the fresh root yield of sugar beet in Hawi-Alwasta location 66.97 , 87.37 and 39.47%. However in Hammam Al-Alil location the first and second levels 2.5 and 5 mg B. L-1 as compared to zero boron resulted in an increase in the yield 2.18 and 39.33% respectively, while the highest level of boron 7.5 mg B. L-1 caused a decrease in yield (-12.19%).The foliar application of boron resulted in an increase in sugar percentage 13.95 , 18.60 and 10.46% in first location and 9.09 , 21.81 and 18.18% in second location as compared to zero boron respectively. However the yield of pure sugar in first location were 0.964 , 1.061 , 1.130 and 0.920 T.D-1 and 0.764 , 0.932 , 1.673 and 0.710 T.D-1 in second location.

To study the effect of magnesium on cation exchange characteristics, soil samples were collected from salt-affected soils of five locations from Al-Jazeera northern irrigation project of Nenava province-Iraq. Cation exchange experiment between Ca and Mg in the presence of sodium was carried out to quantify the Mg on the accumulation samples with ten electrolyte solutions using chloride salts of NaCl, MgCl2.6H2O and CaCl2.2H2O with ratio of Na: Ca + Mg ranging from 1: 9 to 9: 1. the SAR ranging from (0-40) and the total concentration of the chloride solutions was 100 mmolcl-1. Revealing soils preference for calcium and magnesium was conducted by using electrolyte solutions with different Mg/Ca ratios. The results showed that the selectivity coefficient values of Mg-Ca ranged between (0.466-0.810) with an average 0.622 which reflect that Ca and Mg are not identical in their exchange behavior and the studied soils showed a preference for Ca in comparison with Mg. The examined soils had a tendency to accumulate exchangeable Na when Mg rather than Ca was the complementary cation, the Na-Mg systems had between 11.5-23.7% more exchangeable Na with an average of 19%.

The effect of carrot juice on sperm-head abnormalities was studied in white mice after oral administration , in addition to the effect of cyclophosphamide (Cp) and their interactions in different combinations . Results indicated that carrot juice (0.1 , 0.25 , 0.5 ) ml administrated orally had no effect compared to the background baseline abnormalities . Cp (50mg / Kg of body weight) elevated the abnormalities to 9 – 15 times the background level (Negative control) . These abnormalities were lowered due to the natural repair processes to 5 times on time spans 6 days . Treatment of animals with carrot juice before mutagen (Ca/Cp) had great effect to reduce the abnormalities , followed by using the juice with mutagen (Ca+Cp) treatment , while using the juice after administration of Cp had slight effect to lower the abnormalities .Types of abnormalities were studied ; the sperms lost the hook was induced greatly by Cp and by treatment (Ca+Cp) . However , most types of abnormalities such as sperm with atrophic head or with spherical heads , sperm with hammer shaped heads and sperm with rod shaped heads were lowered in general at significant levels (P<0.01) compared to positive control and some abnormal sperms were disappeared such as rod shaped sperms . Using the juice after mutagen treatment (Cp/Ca) was effective in lowering the abnormalities to a significant levels (P<0.01) , but after 6 days and in time depending manner .

10 years old Platanus occidentalis L. had been fallen from Ninava plantation forest to examine the effect of stem height and diameter levels and their interactions on fiber length, fiber lumen diameter, fiber length/diameter ratio, rankle ratio and specific gravity. The results indicated that generally the highest means of fiber length, fiber length/diameter ratio and specific gravity were at the 1st height level (0.3m), then these means decreased gradually by increasing height levels and it reached the lowest mean values at 8th height level (14.3m). the effect of height on fiber diameter, fiber cell thickness and rankle ratio was found to be the lowest mean values at the 1st height level (0.3m), then these means began to increase as height level increased until it reached the highest values at the 5th height level (8.3m), then the mean values of fiber diameter and fiber cell wall thickness decreased gradually until the 8th height level (14.3m), while the lowest mean value rankle ratio was at 7th height level (12.3m) then its value increased a little at the 8th height level. The effect of diameter levels on studied properties showed that the lowest mean fiber length and fiber length/diameter ratio were at the pith, then it decreased gradually until it reached the highest value at the 4th diameter level (near the park). Also it was found that the lowest fiber diameter and fiber cell wall thickness was near the pith, then it increased gradually until it reached the highest value at the 3rd diameter level, then it decreased for little value at the 4th diameter level. The lowest rankle ratio was near the pith, then it increased gradually as the distance get closer to the park. The results also showed that the highest specific gravity was near the pith, then it decreased gradually as the distance become closer to the park until it reached the lowest mean value at the 4th diameter level.

The study aims to using the surface water's drainage system maps which prepared from the aerial photographs to draw the gully erosion maps of Kand Anticline and its surrounding areas in northern Iraq. Gully erosion means and its intensity at different positions of study area were calculated. Its relation with the distributed geomorphological aspects in the study area to determine the effects and deformation of soil that affects an engineering structures such as Weirs and Check Dams. The analysis of gully erosion map which prepared by using computer program (Surfer 32) revealed that. The area has been affected by gully erosion in three zones, where as light gully zone formed 14.95% of the area, moderate gully zone formed 44.33% of the study area and the severe gully zone formed 40.72% of the total area. This show that the area interfere from moderate to severe gully erosion effects.

This study comprised four locally cultivated bread wheat varieties ; (Abu – Ghraib 3, IPA, 99, Tamoaz 2, and Iraq) which were sown in 2003 – 2004 under rain fed and supplementary irrigation (SI) with two levels of nitrogen fertilizer (0 and 80 kg N. ha¯1). The harvested grains stored for 3.5 year under room temperature before measuring the parameters. The purpose of this study was to find out the effect of (SI) and N. fertilizer on some physiochemical properties. The results indicated significant differences in protein contents, seed hardness, granularity, width, thickness, solvent retention capacity and protein sedimentation value among varieties. Nitrogen fertilizer affected all these parameters, the second order interaction had no significant effect. Generally N. fertilizer and varieties had a great influence on these criteria comparing with the supplementary irrigation.
