A factorial pot experiment was conducted according to a completely randomized design (CRD) in greenhouse to evaluate contamination of oleander plant with some heavy metals, based on calculation of international environmental pollution indicators and effect of heavy metals on growth of oleander plant , with three factors and six replications. soil was treated with three heavy metals: Pb, Cd, and Ni, and four combinations: Pb + Cd, Cd + Ni, Ni + Pb, and Pb + Ni + Cd, with two levels of each element: 0 and 120 for Lead, 0 and 10 for Cadmium, and 0 and 70 mg kg-1 for Nickel with six time periods used for sampling: 40, 80, 120, 160, 200 and 240 days after planting, using sandy loam soil. Treatments symbolized as TNi, TCd, TPb, TCd,Ni, TNi,Pb, TCd,Pb, TCd,Ni,Pb, and TO. Results showed an increase in values of bio concentration factor (BCF) of oleander root system for Ni in TNi, TCd,Ni, TCd,Ni,Pb, and TNi,Pb treatments, reaching 0.9, 0.43, 0.50, and 0.77, respectively, and decreased in the rest treatments. Highest values were for Cd in treatment C, which reached 1.57, while it was less to other treatments. Values are lower from one for, oleander plant is considered one of plants that accumulate Cd. Values of BCF were low for Pb. Values of BCF increased with increasing time periods. Values of the bioaccumulation factor (BAC) increased with increase in concentrations of available heavy metals in soil. Values of biological transfer factor (TF) for Cd, Ni, and Pb decreased below value of one. Heavy metals added to soil significantly affected values of plant heights, and plant dry weight.

The present research provides the first comprehensive and integrated taxonomic revision of Picris spp. distributed in the Rawanduz (MRO) district- Kurdistan Region- Iraq, a region where members of the genus have long been considered taxonomically challenging. Two species, the biennial to perennial Picris strigose and annual Picris kotschyi, were documented and examined using detailed morphological, micro-morphological, and anatomical analyses. Plant Materials were collected from natural populations representing different elevations, and a wide range of diagnostic characters were evaluated, including vegetative and reproductive morphology, trichome structure, achene features, ecological preferences, and geographical distribution within Iraq. Anatomical investigations, based on transverse section of stems, leaves, and peduncles, revealed several traits of diagnostic value, such as stomatal type, leaf thickness, vessel arrangement, vascular bundle number, and variation in the indumentum of vegetative and reproductive structures. Notably, the distinction between the two species was strongly supported by the number and structure of glochidiate hooked hairs, heteromorphism versus homomorphism of the achenes, peduncle morphology at fruiting, and the presence or absence of persistent basal collars. These features, when combined, provide reliable and consistent discrimination criteria, particularly in cases where flowering-stage materials alone are difficult to separate. The study also reports new local records for both species within the MRO district, including Halgurd mountain and Safin mountain, contributing to the regional understanding of Picris biogeography. Based on limited population sizes, habitat disturbance, and observed anthropogenic threats, both species are assessed as Critically Endangered (CR) in Iraq according to IUCN criteria. Overall, this work offers the most detailed and updated taxonomic account of Picris in the Kurdistan Region and highlights the importance of integrating morphological and anatomical evidence in resolving complex species boundaries.

Hyoscyamus niger have the main pharmaceutical tropane alkaloids and glycosides in their tissues. The study aimed to enhance the biosynthesis of these compounds by tissue culture techniques. Callus cultures were established from leaf explants on MS medium. Three chemical salts were added separately in different concentrations to the culture medium to evaluate their effects on callus growth and content of pharmaceutical compounds. The results demonstrate that copper (Cu) and cadmium (Cd) decreased callus weights, while the aluminum (Al) did not exhibit any significant effects, compared to the control treatment. However, the HPLC assay proved that the chemical stress caused beneficial effects in promoting the production of alkaloid and glycoside compounds in callus cultures. Succinctly, the highest concentration of Cu (36 mg/L) caused a significant increasing in the content of hyoscyamine, scopolamine, and hyoscyammoside-A. Whereas, Al and Cd at low concentration (5 mg/L) produced the varying significant increasing in the substances of tropane alkaloids and glycosides, compared to the other treatments and the control. These finding concludes that application of chemical elicitation in certain concentrations offer advantageous visions for developing the conditions that related with biosynthesis of medicinal compounds in H. niger.

The experiment was carried out at southwest Baghdad during fall season 2021 and spring season 2022 on the industrial potato of Arsenal hybrid, and the experiment carried out using randomized complete block design with in split plot arrangement with three replicates (4 × 3 × 3). Bio-fertilizer distributed within main plots and interaction between phosphorus levels and Brassinolide growth regulator within sub plot.

The study aimed to investigate the impact of location on the nature of the natural landscape along riverbanks and how the design of this landscape changes based on site-specific variables by establishing a theoretical framework that incorporates the principles of plant element design, considering these influences in the design of urban vegetative scenes. Subsequently, the study seeks to validate this theoretical framework along the banks of the Tigris River in Baghdad, focusing on the case study of Abu Nu’as, a site of cultural and natural significance for the city's residents. Among the key findings of the study is that the efficiency of designing urban vegetative scenes along riverbanks is enhanced through the use of local plant species that are adapted to the natural and cultural environment. This improvement is seen in both aesthetic and functional values of the riverbank due to the visual and functional characteristics possessed by these plants. Planting the appropriate species in designated locations contributes to achieving visual openness, especially with the neighboring areas and the roads perpendicular to the riverbank.

The approach of the Green and Ampt (1911) for describing water entry into unsaturated porous media was critically appraised .Theoritical revision was made of a previous mathematical approach, to give it complete rigor in describing water flow for rectangulary abrupt water content profile. Rigorous rederivation of this equation yielded a straightforward and complete interpretation of the suction head at the wet front w. The suction head w at the wet front is given as the integral of the suction-head-  dependent hydraulic conductivity function K () with the upper limit of the integral being the suction head 0 at the initial water content 0. Furthermore, w is shown to be a constant of the flow process even when G-A rectangular abruptness does not hold. The equation is shown to be the hydraulic conductivity K (1) of the wet region behind the wet front which is a function of the constant averaged water content of the wet region. For experimental data of cumulative infiltration with time, both the G-A and two –term Philip equation were fitted by nonlinear regression. The G-A equation gave better fitting than Philip equation for certain soil texture, but both equations gave a very well fitting (%1error). G-A parameter K1 gave a very good agreement with the measure hydraulic conductivity for all soil studied. The other parameter w was calculated from the fitted parameter a and show values correlated to soil texture in expected .Abruptnen of soil water transient profile was tested using soil moisture probes-GS3.

The research aims to study and identify the most important economic and social factors affecting the marketing surplus of wheat farms in Baghdad Province for the agricultural season 2023 using the regressive regression model. The data were obtained through a questionnaire prepared for this purpose and the study relied mainly on the raw data of a random sample of a total of 150 wheat farmers in the province distributed over the various agricultural units of Baghdad Province. Results showed that the marketing surplus of the wheat in Baghdad province is sold through three channels; the first is marketing to the state by 57%, the second is marketing to wholesalers by 40%, and the third is marketing to brokers by 3%. Results also displayed that the marketing surplus of wheat crop in Baghdad is positively affected by a set of variables, namely the amount of production of the getter, the average selling price per ton, and the efficiency of marketing services, while the marketing surplus is related to wheat is negatively affected by variables of in-kind deductions, family consumption, and loss of harvest and collection. The study recommended the need for nutritional awareness for individuals in rationing wheat consumption from the farm, as well as encouraging the establishment of an efficient marketing system by governmental and non-governmental organizations to market wheat production.

The objective of this study was to evaluate the effect of dietary sesame hulls (SH) on the growth and blood profiles of growing lambs. Twenty-four lambs (initial body weight = 21.8 ± 1.35 kg; age = 75 ± 2.5 days) were randomly assigned to 3 diets. Diets with no SH (CON), 75 g/kg SH (SH75), or 150 g/kg SH (SH150), for 120 days, with 10 days adaptation period, followed by 110 days for data collection. The dry matter, crude protein, neutral detergent fiber, acid detergent fiber, and metabolizable energy intake were greater in the SH75 and SH150 diets than in the CON diet. Conversely, the group SH150 exhibited the highest values (P < 0.05) of ether extract intake. Lambs fed diets containing SH showed greater final body weight, total gain, and average daily gain than those fed the CON diet. Notably, the gain cost was lower for the SH75 and SH150 groups than for the CON diet. Blood parameters did not vary in response to the SH supplementation. Sesame hulls could be an alternative nutritional feed ingredient for growing lambs due to their nutritional value and cost-effectiveness.

A field experiment was conducted during the spring season of 2024 at the College of Agricultural Engineering Sciences - University of Baghdad, to study cultivation sustainability of sunflower influenced by nitrogen fertilization and bacterial biofertilization. A split-plot arrangement within randomized complete block design with three replications was used. The main plots received 0, 25, 50 and 75% of recommended nitrogen, while the sub-plots were sown with seeds inoculated with Azotobacter chroococum, Azospirillum brasilense, their mixture and without inoculation, in addition to application of recommended nitrogen fertilization (200 Kg N ha-1) for later comparison with fertilizer combinations. The Findings showed that application 75% of recommended nitrogen fertilizer was significantly superiority in the leaf area (50.21 dm2), fertility rate (71.95%) and seed productivity (5.577 Mg ha-1). Also, there was a significant increase in the vegetative growth when seeds were inoculated with bio-fertilizer mixture, which led to an increase seeds number (1347.6 seeds head-1) and seed productivity (5.406 Mg ha-1). Significant interaction influence noted on most measured parameters. Regarding the comparison of fertilizer combinations with application of 200 kg N h-1, it was observed that the inoculating seeds with bio-fertilizer mixture or alone reduced about 25% of nitrogen fertilizer recommendation.

A field experiment was conducted to investigate the effect of seed priming and planting dates on the growth of two soybean cultivars. This study was conducted during the summer seasons 2022 and 2023 at the fields of the Agricultural Engineering Sciences - University of Baghdad. A Randomized Complete Block Design (RCBD) split-split plot arrangement was employed, with three replicates and three factors.

The results showed the superiority of the 15th June planting date, with the highest average plant height and crop growth rate. The Shaimaa cultivar exhibited the highest average in leaf area and crop growth rate, while also outperforming in plant height. The seed priming treatment with seaweed extract excelled in leaf area and crop growth rate, while the KCL treatment excelled in plant height. Overall, 15th June planting date and the Shaimaa cultivar showed superiority, along with the seaweed extract seed priming treatment.

This study was aimed to compare and evaluate the increasing or decreasing levels of Hsp70 gene expression of five species of Rosa L, 1735 (the most popular ornamental plant that extended throughout the global with high economic value and great cultural importance), Rosa canina, Rosa damascena, Rosa centifolia, Rosa hybrida and Rosa xanthine through total RNA extraction from plant leaves for the five species then reverse-transcribed to complementary DNA (cDNA) then amplified by RT-qPCR technique as a relative quantitation method .The results demonstrated that gene expression of HSP70 was varied between two seasons, spring and summer seasons. The highest gene expression of HSP70 for the R. canina in summer season was recorded at 1.0000 gene fold and 22.950 Ct value as compared with other treated species show low fold of gene expression (0.0012 - 0.0983) gene folding . Our conclusion is that HSP70 elevated levels of gene expression is crucial for heat stress tolerance precisely in R. canina enabled to maintain maintain vegetative growth and flowering throughout the year

This study aims to examine impact of monetary policy indicators on the agricultural foreign trade in Iraq. In addition, it seeks to examine the causal relationship between these indicators and analysis of the short and long-term effects of economic indicators (exchange rate, inflation rate, wide money supply, and interest rate) on agricultural foreign trade in Iraq for the period 1990-2021. The researcher used econometric analysis using the modern ARDL co-integration methodology. The results showed that the exchange rate had a negative multiplier effect on agricultural exports, reaching (-0.004) at a 2% significance level, and that annual inflation had a negative impact on agricultural exports, reaching (-0.004) at a level of significance of 2%. The level of significance is 1%. As for the broad money supply, increasing money would increase the purchasing power of everyone who owns it, and it reached (2.54) at the level of significance of 5%. As for the interest rate, a rise in the interest rate would reduce the volume of loans and investments and thus affect It had a negative impact on agricultural exports and amounted to (-0.17) at a significance level of 1%. The results of the analysis showed that the exchange rate has a clear impact on agricultural imports, as it amounted to (0.003) at a significance level of 1%, and in comparison, with the interest rate, which amounted to (0.01), which was not significant. As for the broad money supply, as it reached (4.41) at a 5% significance level, the increase in the money supply will be pushed to reduce the value of the currency, which will lead to an increase in agricultural imports. As for the annual inflation rate, which reached (-0.0008), it is not significant, and it is recommended.

The Bekhma Dam was once proposed as a massive solution to Iraq’s growing water challenges. But after decades of political delays, environmental concerns, and engineering complications, it remains incomplete. Instead of waiting for a project of such scale, this study explores more flexible and sustainable options. Using historical discharge data from the Eski Kalak Gauge Station, machine learning (XGBoost) was applied to project future water availability under changing climate conditions. The model showed a clear downward trend in discharge, indicating a dominant dry pattern in the coming decades and reinforcing the urgency of adaptive planning. In response, four upstream dam sites were identified through GIS and DEM analysis and evaluated based on reservoir capacity, topography, and regional fit. Bekhma itself was also reconsidered this time as a scaled-down version supported by those smaller alternatives. The idea is simple: by capturing floods and sediment in the upper basin, we can reduce Bekhma’s dead storage requirement and make those construction more realistic. This integrated approach could deliver the key benefits water security, storage, flood mitigation while reducing cost, social impact, and structural risk. Importantly, the study clarifies that these alternatives are not a complete replacement for Bekhma, but rather a practical and scalable support system to strengthen resilience. The study argues that combining predictive hydrology with decentralized infrastructure offers a smarter path forward for the Greater Zab Basin. Based on these findings, the study recommends adopting the proposed upstream alternatives alongside a reduced Bekhma structure to create a flexible, climate-resilient water management system.

This study aimed to enhance food security in Jordan by improving meat quantity and quality in Awassi sheep through introducing two economical genomic mutations; FecB and CLPG. In this study, a group of 209 Awassi ewes were involved in the study where 10 heads were distributed to each collaborated farmer, then Half of the ewes were inseminated with mutations Carrier’s rams, while the other half was inseminated with rams carrying the CLPG mutation, After the lambing season, a genomic DNA extraction and genotyping process (FRLP) for the newborns was conducted and revealed successful introgression of the mutations, resulting in lambs carrying either the FecB or CLPG mutations. Our results showed the successful introduction of the FecB and CLPG mutations in Awassi sheep, with a considerable number of lambs carrying the mutation, in Jordan the frequencies of the mutations were almost zero but now and after introducing the carrier rams to farmer’s fields it has been increased to 0.41 (as heterozygous FecB genotype) and 0.50 for that CLPG heterozygous genotype (in the supported population). Ewes who were in the first parity their Prolificacy was elevated up to 2.5 lambs/ of those holds the FecB mutation. The new introduction of the mutation to farmer’s fields will contribute directly to the livelihood of the farmers and enhancing food security in Jordan.

This study was aimedto characterize by using two genetic groups of chickens, which were Kurdish indigenous chickens (KK) and commercial Super Harco chickens which bred particularly for dualpurpose (SS),Four combinations were produced by diallel crossing between the two genotypes which are (KK, KS, SK, and SS).. The single nucleotide polymorphisms (SNPs) in the GH genes were identified between genotypes. Additionally, assessment oftheir belong to genotypes relationships with growth efficiency (body weight (BW) at hatching and 3,6,9, 12 weeks of age was carried on. The four genotypes were detected by using polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP) techniques by specific primers and restrictase for GH gene.Our data showed that the AA genotype had more values in KK and SK chickens while AB genotype were more in values in KS. The genotype BB was only more in SS (0.56) birds and no values in KK (0.04), KS (0.25) and SK (0.09) birds. The analysis of chi-square test indicated that SK, SS, males and femaleswhich arein (HWE) Hardy-Weinberg equilibrium (p<0.05). The statistical analysis showed that significantcorrelations (p < 0.05) between the GH and the following parameters: BW at 3, 6, 9 and 12 weeks of age, it was determined that the hetrozygotes AB genotype values were superior in BW (39.00± 0.37 kg) and (38.50± 0. 70 kg) in KS * Male and KS * Female respectively at hatching. On the other hand, KK * Female with AA genotype had the lowest body weight (31.60e ± 0.50, 219.00e ± 2.45, 456.60g ± 1.64, 752.00e ± 1.70 and 1087.00g ± 1.48) kg at day one, 3,6,9 and 12 weeks of age respectively compared to other genotypes. Based on the findings of this study, we proposed that in pure and crosses lines chicken population selection programs, a candidate gene marker for chicken growth characteristics could be the GH gene.

The objective of this study is to identify and quantify perfluorinated substances in different ready-to-eat foods found in the local markets of Baghdad Governorate. The emphasis is placed on these substances due to their extensive use in paper and cardboard packaging materials and the consequential health effects. The analysis utilized liquid chromatography coupled with mass spectrometric detection equipped with electrospray ionization. The values recorded for perfluorinated materials in samples of crispy chicken and french fries were (2.41 and 4.94) micrograms, respectively. As for samples of kebab, pizza, and cake, they were (5.14, 5.80 and 7.32) micrograms, respectively, and samples taken from stored ice cream (15-30–45) days recorded (0.23, 0.42 and 2.26) micrograms, respectively. It was found that the percentage of fat and the amount of perfluorinated substances in foods are directly related, and this is clearly evident from the fact that it was not detected in the French Bread samples, and may be due to the low percentage of fat which amounted to 0.86%., compared to the samples that showed positive results.

The results showed that pH, EC were decreased by 12.7, 65.1%, respectively when applied 0.8% of alum at the irrigation of river water and decreased by 11.9, 61.4 %, respectively when applied 1.0% of alum at irrigation with well water as compared to control treatment. While an increase occurred in CEC of about 20.0 and 19.8% at the irrigation of river and well water, respectively as compared to control treatment.While the addition of all levels of aluminum sulfate (alum) led to a significant effect on the available nitrogen in the soil and the biological yield when treating alum a5, which reached 48.6% and 48.50, respectively.

The study was conducted to investigate the relationship between the polymorphisms of A, B, C, D and E of the apolipoprotein A-1 (ApoA-1) gene with some traits (daily and total weight gain rate and feed conversion rate and efficiency) in 70 samples of common carp (Cyprinus carpio). There were significant differences in the growth traits of the genotypes A, B, C and D of the apolipoprotein A-1 gene compared to the genotype E. The results showed that the genotype C was significantly superior (p≤0.05) in the daily and total weight gain rates and reached the highest value of 0.56 and 39.42 g/fish, respectively, while the genotype E decreased to the lowest value of 0.14 and 9.50 g/fish, respectively. On the other hand, the feed conversion rate recorded highest significant effect (p≤0.05) at the genotype C and reached 5.13 Compared with the E genotype which recorded 9.6, the highest significant effect (p≤0.05) on the feed conversion efficiency trait was at the C genotype at a rate of 19.49% compared to the E genotype which reached 10.41%. We conclude from the above that the ApoA-1 gene may have an effect in improving the productive growth traits in common carp fish through its effect on the quantitative traits associated with the genetic phenotypes.

Soil color a basic quality of assessing pedogenesis and climatic effects hence, may provide valuable insight into soil properties and may serve as a distinctive and straightforward measurable climatic indicator. In this study, surface horizons samples were sampled at depth 0-30 cm by using an auger in ten provinces of Iraq where the climate conditions are different. Although the different physicochemical properties such as (Soil Texture pH, EC, O.M. CEC, CaCO3) were identified in the lab section, the Munsell Soil Color Book was applied in the field to identify the soil color. The result showed a rise in (pH, O.M., CEC, CaCO3, Fed, Clay) based on the color indices BWR, TR1, and TR2 in sub-humid climate areas; however, under the same climatic conditions, EC and CaSO4.2H2O levels were lower. While Xanthization was more common in semi-arid areas, the processes of Melanization and Runification were more active in humid environments. Multiple regression analysis indicated a statistically significant relationship between BWR and CaCO3, as well as between TR1 and CaSO4.2H2O. No significant relationship was detected between TR2 and the soil properties under investigation. Furthermore, linear regression analysis between climate and the BWR soil color index demonstrated a significant association, with value R² = 0.33 at a significance level of 0.01. Research findings demonstrated that Iraqi soil climate shows direct correlation to the BWR index specifically.

This study was aimed to determine the optimal conditions for removing total salinity from an aqueous solution of known salt concentration 10% using four new bacterial strains that are tolerant to high salinity genetically diagnosed and registered in the international gene bank (NCBI). Modified nutrient broth medium (MNB) was used with the addition of 10% sodium chloride. The ability of the bacterial strains to remove total salinity was tested in terms of the decrease in total dissolved solids (TDS), where the highest removal rate was after 72 hours, at a temperature of 30°C, with an inoculum volume of 1.5% and a pH of 7. The removal rates were higher in static cultures in the same conditions compared to using the vibrating incubator at 100 rpm. The removal rate decreased when using a mixture of the cocci strain with the three other bacillus species, and the removal rates were constant when using a mixture of the bacillus strains. Total desalination rates were obtained using bacterial strains (A, B, C, and D) after applying the optimal conditions obtained from this study (94, 91, 90, and 92) %, respectively.
