ROLE OF RELATIVE CODON USAGE (RSCU) ON INFECTIVITY AND VIRULENCE OF FOWL ADENOVIRUS ISOLATED FROM INFECTED IRAQI POULTRY
type: item
description: This study was aimed to investigate the role of codon usage on infectivity and virulence of fowl adenovirus. The PCR amplicon sequence revealed that loop1 has a hypervariable region and is adjacent to loop2 on Hexon A segment, while Hexon B segment has a less variable region. The fiber gene is similar among isolates, with differences associated with the virus. Most belong to fowl adenovirus-4, with others in type 8b and E. The study revealed increased effective nucleotide codons in isolates 5, 33, 44, and 15 in Fiber gene, Loop2, and Loop1genes. The study analyzed the impact of mutation on codon usage, hypervariable regions 1-4, and the effective number of codons by determining high and low effective usage. Fowl adenovirus has hypervariable regions that extend at a specific area along HexA segment. The study found stable regions in viruses with variable nucleotides, indicating their evolutionary capability and abundance of amino acids Alanine, Glycine, Proline, Arginine, and Serine, as detected by relative codon usage calculation. The high usage of these codons may result in mutational pressure, potentially aiding in understanding the infectivity and pathogenicity of Fowl adenoviruses through natural selection.

MICROMORPHOLOGY CHARACTERIZATION POLLEN GRAINS OF SUBGENERA PRUNUS AND CERASUS (ROSACEAE) IN KURDISTAN REGION-IRAQ
type: item
description: This investigation was aimed to study pollen grains of subgenera Prunus and Cerasus. The polleniferous materials were collected from different places of Kurdistan region of Iraq living specimens. Pollen grains of all investigated taxa of subgenera Prunus and Cerasus were isopolar, monad, symmetric, tricolporate, dicolporate and tetracolporate pollens also observed, but very rarely. The pollen grains shape of taxa of subgenera Prunus and Cecasus divided in two groups subprolate and prolate depending on P/E value. While, the size were medium with the exception of P. domestica subsp. italica grains were found to be small in size. The percentage of repeat morphological shape of pollen grains in polar view showed that the triangular outlines shapes of pollen grains were the most repeated, while, in the equatorial view the elliptic outline shapes was dominant in all taxa. Pollen grains surface of studied taxa was showed stri­ate pattern with perforations in the grooves except P. domestica subsp. insititia which appeared striate-reticulate type of exine sculpture. Principal component analysis can recognize 67.7 % of the total variability thus can help prediction of taxa.

INFLUENCE OF EXOGENOUSLY APPLIED GLUTATHIONE AND GIBBERELLIC ACID IN A BEAN UNDER SALT STRESS IN VITRO CONDITIONS
type: item
description: This stady was aimed to investigate effect of treatment with 0, 0.25 and 0.50 mM of Glutathione (GSH) and 0, 1.0 and 2.0 mg L-1 of Gibberellic acid (GA3) in enhancing the growth of calli cultures was tested under normal and critical concentrations of sodium chloride (NaCl). The experiments were conducted during October, 2022 to June 2023 at the plant tissue culture laboratory in Center of Desert Studies, University of Anbar. The experiments designed according to the complete randomized design (CRD). The critical limit of NaCl in calli cultures was determined after 35 days of cultivation in MS medium. The results showed that the concentration of 200 mM caused the highest significant decrease in the fresh weight (FW) and relative fresh weight (RFW) of these cultures, which amounted to 457 mg and -0.086, respectively. However, it did not differ significantly with what was produced by the concentration with 150 mM. As for the salinity experiment, the combination of 0 mM + 0.5 mM + 2.0 mg L-1 for each of NaCl, GSH, and GA3, respectively, was the most consistent in improving the study indicators. This combination achieved the highest significant average for FW, dry weight (DW), RFW, and the effectiveness of Catalase (CAT) which amounted to 973.7 mg, 52.8 mg, 0.947, and 13.119 U mg-1 protein, respectively. However, the combination with the combination of 0 mM + 0.5 mM + 1.0 mg L-1 for each of NaCl, GSH and GA3, respectively, were recorded the lowest significant level of Malondialdehyde (MDA) content, which amounted to 1.951 µM g-1 FW.

OPTIMIZING SOLAR OUTPUT TO REDUCE PHOTOVOLTAIC PANEL NUMBER IN IRRIGATION
type: item
description: This experiment aimed to study the effect of integrating a passive cooling system with varying air passage outlet clearances: 0 cm (C0, control), 10 cm (C1), 15 cm (C2), and 20 cm (C3) on the performance of polycrystalline and monocrystalline PV panels used in solar-powered irrigation systems. Performance metrics included PV efficiency, maximum power, required number of panels, and operational costs. Results showed a highly significant effect (P < 0.0001) of air passage clearance and PV type on all measured parameters. Specifically, the 10 cm clearance (C1) yielded the best outcomes, achieving the highest PV efficiency (16.26%), maximum power (41.12 W), lowest panel number (7), and lowest operational cost ($8.75). Among panel types, polycrystalline panels demonstrated superior efficiency (12.52%), maximum power (32.05 W), required fewer panels (11), and incurred lower operational costs ($13.50) compared to monocrystalline panels. These findings indicate that optimizing passive cooling can significantly enhance PV performance while reducing system size and costs.

type: item
description: A field experiment was conducted at the Al-Raed Research Station, located 25 km west of Baghdad, to investigate the effects of machine speed and plowing depth on various performance indicators of a mechanized unit. A combined implement was utilized to simultaneously perform multiple agricultural operations. The experiment employed two main factors: forward speed of the mechanized unit, with three levels (1.004, 2.03, and 3.048 km h-1), and plowing depth, with three levels (5, 8, and 10 cm). The performance indicators studied included slip percentage, operating costs (IQD ha-1), the number of soil clods larger than 22 mm in diameter, and Emergence percentage. Through the results obtained in the experiment The initial operational speed of 1.004 km h-1outperformed other treatments in terms of minimal slip (5.48%), reduced soil clod size (17.00 clods/m² > 22 mm), and higher maximum Emergence (85.30%). Nevertheless, it incurred the highest operational cost of 17807 dinars ha1-. Conversely, a plowing depth of 5 cm resulted in the lowest slip (7.42%), cost (15408 dinars ha1-), and soil clod count (18.30 clods/m²), while maintaining a high Emergence rate (84.90%). nested design with a completely randomized block design (RCBD) was adopted.

ANTIHYPERTENSIVE AND ANTIOXIDANT FUNCTION OF ENZYMATIC HYDROLYSATE FOR BARLEY PROLAMINE
type: item
description: This study was aimed to identify the role of barley prolamin (BP) hydrolysates which prepared from local barley (class Ibaa 99), prolamins isolate using pepsin and trypsin (individually - synergistically) in inhibiting the ACE 1 and as antioxidant agent. The Amino acids (AAs) content of barley protein were estimated by HPLC technique, and barley prolamin (BP) was isolated from whole barley flour (WBF) using 70% ethyl alcohol, and then purified depending IP and centrifugation. Prolamin molecular weight (M.wt) was determined using the electrophoresis technique. Barley prolamin isolate (BPI) subjected to enzymatic hydrolysis using 20U of pepsin and trypsin separately and synergistically for 8 h. Aliquot of the BPI hydrolysate was taken every 60 min to determine the degree of hydrolysis (DH%), antioxidant and antihypertensive properties. The results showed that barley protein contained 22 amino acids, and the percentage of the essential amino acids (EAA) and polar amino acids (AAs) were 35.08, 45.86 % of the barley protein composition, respectively. Prolamin constituted 24% of the total barley proteins and the BPI contained 90.5% protein. Electrophoresis pattern showed that most of the prolamin bands have M.wt about 34-55 KD. Synergistic hydrolysis of BPI gave the highest values for DH (50.68 %) after 8 h hydrolysis. The antioxidant function included the radical scavenging activity (RSA) and reducing power (RP) of hydrolysates was directly proportional to the DH%. The highest RSA value was 45% in the pepsin hydrolysates sample, and the highest absorbency for RP assay was 0.69 by synergistic hydrolysates sample after 8h. Bitter taste appeared in hydrolysates prepared by Pepsin and synergistic hydrolysis after 7h. The ACE 1 inhibition activity was proportional to the DH%, and the maximum activity reach to 81.44% after 8 h in pepsin hydrolyzed samples.

AN ECONOMIC ANALYSIS OF THE IMPACT OF TRADE OPENNESS ON AGRICULTURAL OUTPUT GROWTH IN IRAQ FOR THE PERIOD 1990-2020
type: item
description: This research aimed to measure the impact of trade openness and changes in the terms of trade on the growth of agricultural domestic product in Iraq for the period 1990-2020. The independent variables were represented by indicators (trade openness, agricultural exports, the rate of trade of agricultural crops, and the exchange rate). The Autoregressive Distributed Lag Model (ARDL) measures the relationship between variables, in addition to the PP test for the stability of the time series. After the estimated model passed the bounds test, the short-run and long-run functions were estimated. The results of the estimation in the short run showed the existence of a positive effect of both terms of trade and the exchange rate on the growth of agricultural domestic product. As for the rate of trade openness, its effect was negative, and the results did not prove significant for the agricultural export index. In the long term, it was significant. As for trade openness, its effect became positive due to the growth of exports in the long term. The results indicated that the terms of trade are not in the country’s favor, due to the small volume of agricultural exports.

AN ECONOMIC ANALYSIS OF THE FACTORS DETERMINING THE ROLE OF RURAL WOMEN IN AGRICULTURAL PRODUCTION IN BAGHDAD GOVERNORATE.
type: item
description: The study aims to determine the impact of economic and social determinants on the size of women's contribution to agricultural work. The research used qualitative response models to determine the impact of the explanatory variables (age, marital status, educational level, training skills, experience in agricultural work, NGO support, health status, family size, experience in secondary agricultural work, use of agricultural machinery in plant production) and their impact on the variable affiliated with the participation of rural women for a random sample of (384) women in separate rural areas in Baghdad Governorate. The results of the analysis showed that the size of the family and the use of mechanization had a negative and weak effect on the contribution of women. As the increase in the size of the family leads to an increase in its household burdens at the expense of its work in farm work. And because the use of mechanization is limited to men, the increased use of technology, especially modern ones, works to reduce women's working hours on the farm. The rest of the variables had a positive and significant impact on their contribution. Accordingly, the research recommends the provision of health and educational services for women, as well as their involvement in training, extension, and economic and financial empowerment programs to raise their contribution to achieving sustainable agricultural development.

EVALUATION OF INHIBITORY ACTIVITY CHITOSAN NANOPARTICLES LOADED ON BASIL OIL AGAINST PSEUDOMONAS AERUGINOSA BIOFILM FORMATION
type: item
description: The increasing resistance of Pseudomonas aeruginosa to antibiotics has complicated the treatment of infections due to its various virulence factors. One of its major pathogenic traits is the ability to form thick biofilms, which allow the bacteria to adhere to living or nonliving surfaces and enhance drug resistance. Consequently, exploring safe and effective therapeutic alternatives from plant sources has become essential for combating this multidrug-resistant pathogen. In this study, essential oil of Ocimum basilicum (BEO) was extracted via distillation and analyzed by GC-MS. The BEO was then loaded onto chitosan nanoparticles (BEOCSNPs) prepared using the ionic gelation method with tripolyphosphate (TPP). The nanoparticles were characterized using UV–vis, FTIR, SEM, and XRD techniques. Clinical isolates of Pseudomonas aeruginosa were obtained and identified with the VITEK-2 system. The minimum inhibitory concentrations (MICs) of BEO and BEOCSNPs were determined using a 96-well resazurin-based microdilution assay. The MIC of BEO ranged from 190 to 95 µg/mL, whereas the MIC of BEOCSNPs was significantly lower, ranging from 3.75 to 0.93 µg/mL. The inhibitory effects at sub-MIC concentrations were assessed by measuring optical density in a 96-well microplate using 0.1% crystal violet staining, which showed a significant decrease in biofilm formation. The biofilm inhibition activity of BEOCSNPs was notably higher in isolates P16 and P22, with inhibition percentages of 84.28% and 79.32%, respectively. In comparison, BEO alone inhibited P16 and P22 at 66.74% and 57.43%, respectively. These results indicate that Ocimum basilicum essential oil loaded onto chitosan nanoparticles exhibits superior inhibitory activity against biofilm formation of Pseudomonas aeruginosa compared to the essential oil alone.

description: Optimizing the allocation of agricultural machinery is crucial for enhancing rice production efficiency, particularly in regions with uneven resource distribution. This study addresses the lack of localized, data-driven mechanization strategies in Kubu Raya Regency, bridging an important research gap in sustainable resource allocation. It focuses on Sungai Kakap and Kubu subdistricts in Kubu Raya Regency, West Kalimantan, to develop and prioritize the distribution of hand tractors, cultivators, and power threshers based on land area, cropping index, and existing saturation levels. Primary data were collected through structured interviews with a representative sample of agricultural stakeholders, while secondary data included rice production levels, machinery availability, and land use statistics. The results identified Tanjung Saleh and Kampung Baru as high-priority villages due to extensive paddy field areas, high cropping intensities, and critically low machinery saturation levels. Addressing these shortages can significantly enhance land preparation, planting efficiency, and post-harvest processing, leading to increased productivity and reduced operational costs. A validated coefficient approach and stakeholder engagement were integrated into the prioritization framework to ensure robust decision-making and policy relevance. The proposed prioritization framework offers a data-driven approach for equitable machinery distribution, supporting sustainable agricultural development and regional food security. Beyond Kubu Raya, these findings provide actionable insights for policymakers and practitioners seeking to refine agricultural resource allocation strategies in similar contexts. This study thus proposes a foundation for future research on optimizing agricultural mechanization, highlighting potential benefits for policy and practice at both local and broader scales.

ANALYSIS OF DROUGHT-TOLERANT GENOTYPES IN SORGHUM USING MULTIVARIATE ANALYSIS TECHNIQUES
type: item
description: This study was conducted during the spring and fall seasons of 2024. The results showed a significant positive correlation between the three indices and productivity under both drought stress conditions (Ys) and non-stress conditions (Yp). This indicates that these indices are effective in identifying Genotype with high productivity potential in both scenarios. In the spring season, the superior Genotype were G7 (Giza 113), G14 (ACSAD 51), G15 (ACSAD 56), G20 (ACSAD 62), and G23 (ACSAD 66). In fall season, the top-performing Genotype were G8 (Tabet), G10 (Uruk), G17 (ACSAD 47), G20 (ACSAD 58), and G25 (ACSAD 68). All these Genotype demonstrated drought tolerance with high productivity under both stressed and non-stressed conditions. The indices used in this study help in identifying Genotype with a high ability to withstand drought, thus enhancing their effectiveness in challenging environmental conditions. Additionally, the aforementioned Genotype are considered suitable for use in crop improvement programs in the central region of Iraq, due to their ability to adapt to drought conditions and maintain good productivity under varying circumstances.

MONITORING LAND COVER FIRES USING SPECTRAL INDICES AND SATELLITE DATA
type: item
description: This study aimed to monitor and evaluate the impact of fires on the appearance of the land surface in open and flat agricultural areas using spectral indices and Landsat8 Operational Land Imagery (OLI) satellite images. A representative area, covering 250.34 km², was selected in Nineveh Governorate in Iraq lies between latitudes (43˚ 20′ 0̋-43˚ 32′ 30̋) N and longitude (36˚ 25′ 0̋-36˚ 11′ 0̋) E on June and July 2019 in order to determine the burned area on the land, and use the resulting spectral signature to generalize it to the rest of the study area. Data from the American Landsat satellite, GIS software, and spectral indicators for vegetation covers, such as the Normalized Difference Vegetation Index (NDVI), the Soil-Adjusted Vegetation Index (SAVI), and the Normalized Burning Ratio index (NBR), were used to extract the results. Then, the Land Surface Temperature index (LST) and the difference Normalized Burning Ratio index (dNBR) were used to measure the validity of the results and the severity of the fires, respectively. After using and performing corrective processing of the spectral indices, applying the three indices and determining the difference between them for a short period of time, it was possible to discover the areas of fires and the proportions of their effects. The NDVI results showed that the area affected by very severe degradation increased due to the fires to 39.29%, while the LST increased from 47.70 to 48.39 degree. The study concluded that the area of ​​fire spread can be determined when there is a discrepancy in the pattern of spatial data that are close in date of capture and by using spectral indices.
