Effects of Different Parent Materials and Toposequence on status and distribution of Iron Oxides in Some Soils of Sulaymaniyah Governorate / Iraq
type: item
description: Three transects were chosen in Sulaymaniyah governorate / Iraq. The first was located within the Bazian Plain, while the second was in Sulaymaniyah plain, and the third was located within the plain of Shahrazur, in order to study the effect of parent material and toposequence on the status and distribution of Iron oxides in these soils. Results Shows that there is a differences in the amount and distribution of free iron oxides between the studied pedons, and even within one Pedon. These differences can be attributed to the effect of the difference in the parent materials and topography. Also, the soils developed on Basalt rocks and Red Mudstone were characterized by their high iron oxides and dark brown color, while those developed on Limestone rocks were characterized by their low iron oxides and yellowish brown color. The topographic location also, affected the transport of weathering products of parent rocks from elevated areas and deposed in the plain areas.

type: item
description: The recent research aims to collect fungal fruiting bodies from the Iraqi environment / Baghdad Governorate /Al-Salihiya and diagnose them morphologically and molecularly using the polymerase chain reaction (PCR) technique.The fruiting bodies obtained from wild mushrooms were subjected to quantitative and qualitative analysis using HPLC to detect biologically active phenolic compounds in the fungus. The effect of some physical factors and conditions on the growth rate of fungal mycelium and its density was also studied in terms of (temperature, pH, type and concentration of materials used in preparing the media in addition to the effect of light and darkness factors). The results of BLAST analyses showed that there is a 99% match between the genes of the local isolate and the fungal strains belonging to the edodes species. This local isolate is designated by the symbol (EkRu-Bagadad-1) and the sequence (OM432157). Regarding the phenolic compounds profile, the results showed that the mushroom contains 15 phenolic compounds, which included 6 phenolic acids (Vanillic, Chlorogenic, 4-hydroxyl benzoic, Caffeic, Gallic, Cinnamic,) and 9 flavonoids (catechol, cinnamaldehyde eugnol, quercetin, nigellone, rutin, Pyrogallo, lignans, kaempferol). The total phenolic compounds in the mushroom amounted to 661.64 mg/L, and 4-hydroxybenzoic acid was the most concentrated phenolic acid in the mushroom. The results also showed that the highest growth rate of radial mycelium of the local strain of Shiitake mushroom was achieved in potato peel medium at concentrations of 20 gl-1 , which reached (0.473 cm/day). The local strain under study recorded the highest growth rate in all culture media used at pH (6) and temperature 23 C. The results also showed that the growth rate in the dark was higher than the growth rate in the light in all natural media used.

ESTIMATING THE EFFECT OF URBAN GROWTH ON CURVE NUMBER USING GIS IN THE ERBIL SUB-BASIN OF THE KURDISTAN REGION OF IRAQ
type: item
description: The urban development of areas directly affects hydrological processes by changing patterns of surface runoff. Cities growing experience increased flood risks as natural water absorption is reduced by changing permeable ground with structures non-absorbent. The research analyzes how expansion of urban between 2017 and 2023 influenced the Curve Number (CN) in the Erbil Sub-Basin, 1318 km2 using (GIS). This study stands differ from earlier research by focusing solely on how LULC changes affect CN values without considering precipitation data. The study achieves a more precise understanding of urbanization impacts on hydrological responses through its precipitation-independent methodology. This research methodology utilizes high-resolution satellite imagery along with soil classification maps and digital elevation models (DEMs) to determine transformations in land use and land cover (LULC). This study uses the Soil Conservation Service Curve Number (SCS-CN) method to analyze runoff changes caused by urban development. CN values steadily grew from 80.53 in 2017 to 81.50 in 2023 as agricultural and barren lands transformed into urbanized spaces. The growing trend points to an increased risk of urban flooding while decreasing groundwater recharge which makes it essential to develop sustainable water management practices.

A FUZZY-AHP AND GEOSPTIAL ANALYASIS MODEL FOR LAND SUITABILITY ASSESSMENT OF DATE PALM (Phoenix dactylifera) CULTIVATION IN NORTHREN BASARAH, IRAQ.
type: item
description: This study was executed in the northern part of Basrah Governorate in southern Iraq to evaluate the suitability of lands for date palm cultivation by integrating fuzzy logic, remote sensing, and geographic information systems. Nine criteria were studied, including chemical properties (EC, pH, O.C, CaCO₃, and CEC) and physical properties encompassing soil particle size distribution, soil depth, and soil bulk density, in addition to the supervised classification map. The importance and influence of all criterion have been determined through a Multi-Criteria Decision-Making (MCDM) method. Fuzzy logic was then employed to develop a specific mathematical model for evaluating land suitability for date palm cultivation and to produce a land suitability map for study area. 73.96% of the studied lands are unsuitable (N1), while moderately suitable (S2) lands constituted 15.45%, and marginally suitable (S3) lands constituted 10.59%. Lands that classified as S1 were missed due to urban expansion, high soil salinity, high carbonate minerals, and unsuitable soil depth for date palm cultivation. moreover, the developed mathematical equation can be applied to assess land suitability for date palm cultivation in areas with similar conditions to the study area.

SEQUENCE DIVERSITY AND MOLECULAR EVOLUTION ANALYSIS OF INTERNATIONAL TOMATO BASED ON THE ENTIRE ITS REGION
type: item
description: This study aimed to assess the genetic diversity and molecular evolution of tomato (Solanum lycopersicum) populations from various countries, which hold significant potential for future breeding strategies and germplasm conservation. To achieve this, a total of 15 sequences deposited in GenBank were analyzed using the complete internal transcribed spacer (ITS) region of the nuclear ribosomal DNA (nrDNA). The spacer sequence lengths ranged from 156 base pairs (bp) in the Swedish tomato to 713 bp in the Palestinian tomato. A notable variation in GC content was observed, with the Thai tomato exhibiting the highest value (67.48%) and the South Korean tomato the lowest (49.56%). Phylogenetic trees were constructed using both the distance-based Neighbor-Joining (NJ) and Maximum Parsimony (MP) methods. Sequence analysis revealed 38 monomorphic (invariable) sites and 15 polymorphic sites, of which 14 were singleton variable sites and one was parsimony-informative. Alignment of the 15 sequences enabled the identification of five haplotypes. The estimated transition/transversion bias (R) was 17.339, indicating a greater frequency of transitions over transversions in this region. Neutrality tests, including Tajima’s D and Fu and Li’s statistics, produced statistically significant results. The highest levels of genetic diversity were observed in South Korean, Iraqi, and Indian tomato samples.

EVALUATION THE EFFECT OF SYNTHESIZED ZINC OXIDE NANOPARTICLES FROM MYRTUS COMMUNIS L. LEAVES EXTRACT ON ESCHERICHIA COLI
type: item
description: This study was aimed to estimate the effect of zinc oxide nanoparticles synthesized by Myrtus communis L. on the expression of the adhesion genes fimH and fimA in isolates of uropathogenic Escherichia coli (UPEC). The biosynthesized-ZnO NPs was characterized through several techniques including UV–vis spectral analysis, atomic force microscopy (AFM), Field Emission Scanning Electron Microscope (FE-SEM) and Fourier transform infrared (FTIR). For determination of MIC and sub-MIC of ZnO NPs, only 7 multi-drug resistant (MDR) and strong-biofilm producer E. coli isolates (harbored both fimH and fimA) were selected based on our previous work. Microtiter plate method was utilized and the results indicated that only three isolates (C1, C2 and C23) with MIC and sub-MIC (125 and 62.5 µg/ml), respectively, were selected for further experiments. Quantitative Real Time PCR was utilized for determining the gene expression of fimH and fimA in three isolates (C1, C2 and C23), with and without treatment with ZnO NPs. According to the results, the relative expressions (2-ΔΔCt) of fimA gene in C1, C2 and C23 isolates of E. coli were downregulated in 0.51-fold after treated with 125 µg/ml of ZnO NPs, while the relative expressions (2-ΔΔCt) of fimH gene in C1, C2 and C3 isolates of E. coli were upregulated in 4.42-fold after treated with 125 µg/ml of ZnO NPs.

Study of some plant species as phytoremediation of heavy metals emission from oil refinery
type: item
description: This study was carried out to investigate the phytoremediation potential of six different plant species (Melia azedaracch ,Punica granatum,Cupressus arizonica, Platanus orientalis and Platanus orientalis) in the city of Erbil mitigating heavy metal emissions of an oil refinery. The research assesses photosynthetic pigments, heavy metal concentrations (Fe, Cu, Mn, Ni, Zn, As, Pb, Co, Hg and Se) from an oil, and biochemical attributes in leaves, highlighting their responsiveness to contamination. Variations in metal levels between control and polluted sites underscore the refinery's impact, while reduced photosynthetic pigments indicate potential ramifications for plant vigor. The intricate interplay between pollution levels and plant physiology is explored, offering crucial insights for effective environmental management strategies. Metals like Arsenic, Cadmium, Lead, and Mercury, commonly found in food, pose health risks due to human activities. The research underscores the significance of plants as indicators and reducers of pollutants, emphasizing the potential of phytoremediation in addressing environmental challenges. The findings contribute valuable information for developing sustainable approaches to combat pollution, particularly in industrial settings

GENETIC DIVERSITY INDICATORS IN SPP1 GENE OF LOCAL AWASSI EWES IN MIDDLE OF IRAQ
type: item
description: This study was conducted to identify the genetic diversity indicators of the secreted phosphoprotein 1 (SPP1) gene in flock of local ewe's sheep in middle of Iraq. The sample was made up of 48 ewes and the duration of the study was six months. Genetic polymorphisms were identified and four SNPs (4) variants were obtained. The average allelic abundance (Na) was 2.00, the average number of alleles affected (Ne) was 1.0539, Shannon Guide (I) 0.1163. The average allelic abundance was equal in all the variations studied (2.00) and the number of alleles affected was higher in SNP2 and SNP3, both at (1.0425) compared to SNP1 (1.0211) and SNP4 (1.1096). Obs-Hom and (0.9479) are very close to Exp- Hom and (0.9492). The individual's evidence of persistence within the Fis clan of the G, A, C and T allels of local sheep were -0.0367. The Fit's aggregate stability manual obtained according to SPP1 gene analysis is also -0.0367. Therefore, we can conclude that there is no genetic drift that causes genetic differentiation of the local sheep's sample and this may be due to the large number of rams used by matting, thereby creating an appropriate variation in flock.

ASSESSMENT OF SOIL EROSION RISK USING RUSLE IN SELECTED WATERSHEDS OF SULAIMANI PROVINCE, IRAQ
type: item
description: This study was aimed to assess the risk of soil erosion in 32 watersheds of Sulaimani province, Kurdistan/Iraq, based on Revised Universal Soil Loss Equation, GIS and RS data. The annual precipitation data were used to generate the rainfall-runoff erosivity factor using the previously developed equation for the region. The soil erodibility factor was estimated using soil particle size distribution data. The topographic factor was generated using a digital elevation model from a sentinel 2. The cover-management factor was determined by using Google Earth Engine with Landsat7 and Landsat8. While the soil erodibility and vegetation factors did not show high spatial variability across the province, rainfall erosivity showed an increasing trend from south west to north east of the region, ranged from 73 to 632 MJ mm ha-1 h-1. The results showed that the average annual soil loss for the different watersheds ranged from 2.12 to 62.05 t ha-1 y-1. The results also indicated that the main factors governing soil erosion in Sulaimani province are rainfall intensity, rugged topography, steep slopes, and sparse vegetation.

AN ECONOMIC ANALYSIS OF THE RELATIONSHIP BETWEEN AGRICULTURAL TRADE OPENNESS AND AGRICULTURAL GROWTH IN IRAQ FOR THE PERIOD (1990-2021).
type: item
description: The research was conducted to evaluate the link between agricultural trade openness and Iraqi agricultural development through the use of annual time series data from (1990–2021). This research that focuses on the Iraqi case study, as a developing country that opens up to the Global industry, and aims to identify the position of openness in facilitating agricultural development. The Research question centers around the effects of agricultural trade openness to agricultural growth or vice versa. The analysis is based on the examination of the secondary data utilizing statistics such as ARDL (Auto Regressive Distributed Lag) and co-integration analysis. The relevance of the findings results in understanding the complex causal relationship between agricultural trade openness and agricultural growth. The research conclusions indicate that the high agricultural trade openness index means that the Iraqi economy is highly dependent on the outside world, which weakens the economic and political ability to confront fluctuations in economic activity. The impact of the agricultural trade openness policy in Iraq depends on the performance of the economy in general and the quality of imported goods in particular. The co-integration test of the ARDL model shows the existence of a long-term balanced relationship between the dependent variable. The research recommends the need to enhancement the competitiveness of major agricultural products and adopts encouraging policies to enhance export. It also highlights the importance of developing effective agricultural policies that provide the necessary support to farmers, to adapt to the changes resulting from trade openness.

EFFECT OF PARTIAL REPLACEMENT OF WHEAT AND RICE FLOUR BY MODIFIED STARCH ON CAKE AND BISCUIT QUALITATIVE AND SENSORY PROPERTIES
type: item
description: This study was aimed to investigate the effect of substituting different proportions (10%, 20%, 30%) of wheat flour and Amber rice with enzymatically modified starch on qualitative and sensory characteristics of biscuits and cupcakes. The results showed a decrease in the thickness of wheat biscuits with an increase in the substitution percentage . The 30% substitution showed a significant difference compared to the others . Conversely, there was an increase in the diameter of biscuit samples, ranging from (42.00-48.30 cm), as well as the spread factor. The 30% substitution treatment showed a significant difference compared to the others. As for rice biscuits, the diameter and the spread factor values increased with increasing substitution rates. Sensory evaluation for rice and wheat biscuits indicated that substitution rates of (0, 10 and 20)% achieved similarity in aroma , taste, symmetry of form, and crumb color. However, substitution rates of 30% for both products showed a darker color, more hardness, and the development of an acidic flavor . As for the cupcakes, the specific volume decreased with increasing substitution rates. The highest values for wheat cakes were recorded at substitution rates of 10% and 20%,being 3.19 and 3.00 cm3 /g respectively. The lowest values were recorded for WC3 and RC3 (2.60 ,1.61cm3 /g). The sensory evaluation for the cupcakes samples showed no significant differences as compared to the control sample in term of moisture, texture smoothness, crumb color, and crust color. Substitution at 10% and 20% showed similarity in terms of symmetry of form, crumb homogeneity, aroma ,taste and moisture. However, the 30% substitution rate resulted in a noticeable decline in product acceptance due to a decrease in volume , texture smoothness, reduced crumb homogeneity, as well as a darker color and an undesirable flavor

ANALYSIS OF THE IMPACT OF THE GREEN ECONOMY ON SUSTAINABLE AGRICULTURAL DEVELOPMENT IN IRAQ FOR THE PERIOD (2003-2022)
type: item
description: The research aims to study the impact of the green economy on achieving sustainable agricultural development in Iraq for the period (2003-2022). The research used quantitative methods in analyzing GDP, green GDP, investment allocations for the agricultural sector, environmental allocations, cultivated areas and water imports of the Tigris and Euphrates rivers to distinguish the impact of these variables on agricultural GDP. The parameters were estimated using the Autoregressive Distributed Lag-ARDL framework. The results found that each of the green GDP, investment allocations, and environmental allocations came positive and consistent with the logic of the economic theory, while cultivated areas came positive but not significant. Rivers water flow had a negative signal due to the significant decline during the study period. The research found that the green GDP has the largest effect in agricultural GDP, and its impact is clear in advancing the development process. The research recommended the need to follow scientific methods and modern methods to reduce toxic and greenhouse gas emissions, which greatly affect pollution and agricultural production

MORPHOLOGICAL AND MOLECULAR DESCRIPTION OF NEW RECORD OF METARHABDITIS RAINAI (NEMATODA: RHABDITIDAE) FROM BAGHDAD
type: item
description: Aim of this study was to identify and characterize the entomopathogenic nematode Metarhabditis rainai, which was isolated from soil samples carried out from Alrashdya at (33˚25ˈ13.4̎ N 44˚21ˈ45.3̎ E) Baghdad- Iraq and was illustrated by both morphological and molecular aspects. All specimens of M. rainai were cultured, identified and described using some morphometric criteria based on standard available key. Selected specimens (Zah, IQ2 OR960470 isolate) of this species were characterized by the body length of male was ranged from (377.49 – 563.89 μm), the body length of female was (857.44 – 1111.7 μm) and the body length of juvenile was (419.28 – 757 μm). Using partial 18S rRNA gene sequences, molecular characterization was performed on selected specimens of this species. The 18S-rRNA sequence of the Zah, IQ2 OR960470 isolate showed a sequence homology ranging from (88.50% to 100%) with the 18S rRNA sequence of M. rainai found in the NCBI database. The phylogenetic tree has been created to separate M. rainai species from closely related genera and species. Metarhabditis rainai Zah, IQ2 OR960470 isolate marks the first record of M. rainai in Iraq.

EVALUATION ANTIBACTERIAL AND ANTIBIOFILM ACTIVITY OF Cymbopogon citrates L. ON FIMA AND PAPC GENES AGAINST Escherichia coli
type: item
description: This study was aimed to evaluated the antibacterial activity on Cymbopogon citrates ( C. citrates ) leaves extract and assessment of its effect on fimA and papC genes in Escherichia coli ( E.coli )isolates. Rotery apparatus were used to prepare aqueous and methanolic extract; total phenolic content and high-performance liquid chromatography (HPLC) were conducted to determine the active compounds in the extract. The results showed that the methanolic and aqueous extracts contain seven flavonoids derivatives ( Catechine , Chlorogenic acid , Ferulic acid , Gallic acid , P-Coumaric acid , Qurcetine and Kaempferol ) in varies ration were identified on the basis of matching retention time with the standards. The total phenolic contents were 19.56 and 47.45 mg/g in 50 mg/ml, in aqueous and methanolic extracts respectively. The antibacterial activity of C. citrates leaves extracts showed that the aqueous extract was less effective than methanolic extract in concentration 16 mg/ml. Moreover, the result of the minimum inhibitory concentration (MIC) showed that the methanolic extract on E.coli isolates was 16 mg/ml, while the MIC values of aqueous extract were 32 mg/ml. C. citrates methanolic leaves extract had antibiofilm activity, which inhibits 90% and 100% of the biofilm formation of E. coli in concentrations 16 and 32 mg/ml respectively. The result of the gene expression revealed that there is a decrease in the expression of the fimA and papC genes.

GENETIC VARIABILITY AND MOLECULAR EVOLUTION OF THE IRAQI DATE PALM CULTIVARS USING INTERNAL TRANSCRIBED SPACER 1 (ITS1) REGION OF NUCLEAR RIBOSOMAL DNA
type: item
description: This study was aimed to investigate genetic diversity of nine Iraqi date palm cultivars (Phoenix dactylifera L.), two of them were propagated by tissue culture tiqneque. The variation in GC content in the ITS1 region was recorded at (52–53%) with an average of (52.7). The data suggests that transitions have a lower frequency compared to transversions in this region, where the overall bias R for transition/transversion has been estimated at (0.661). The aligned sequences associated with internal transcribed spacer 1 (ITS1) showed intraspecific variation, and the matched sequences enabled the identification of all cultivars studied as haplotypes. Phylogenetic trees constructed using distance-based ''neighbour-joining'' (NJ) and ''maximum parsimony'' (MP) techniques provided strong evidence for the independent structure of the considered accessions. Tests of molecular evolution reveal that the internal transcribed spacer 1 (ITS1) evolved in accordance with a precise neutrality paradigm. In a population predicted to be in equilibrium after the 6th generation, suggesting a recent demographic expansion in the Iraqi date palm population.
