Due to the low-fat content and its richness in fatty acids, especially the saturated ones, and lower cholesterol levels
than mutton and beef, many consumers prefer broiler chicken meat. However, the refrigerated storage may lead to
chemical alterations and microbial proliferation in the meat product, generating metabolites that induce physical and
chemical quality changes in the chicken meat. Thus, the study focuses on chicken meat\'s oxidation of lipids and proteins,
microbial degradation, and physicochemical attributes during refrigeration. The study involves 30 forty-two-day-old
ROSS broiler chickens with an average live body weight of 2.023 ± 0.017 kg at a commercial plant in Erbil, Kurdistan
region of northern Iraq. After bleeding and evisceration, chicken breast muscle samples were divided into three portions,
then tagged, vacuum-sealed, and stored in a 4°C refrigerator for 1, 3, and 5 days. In this study, there were increased
activities of microbes, including lactic acid bacteria, Enterobacteriaceae, pseudomonas species, and total aerobic counts
(P≤0.05) as the days of ageing went up. The thiobarbituric acid reactive substances, carbonyl, and free thiol contents
changed significantly as the meat ages for 1, 3, and 5 days. Similarly, the refrigerated storage of broiler chicken meat was
significantly reduced the value of colour, muscle pH, WHC, drip loss, cooking loss, and heavy chains (actin and myosin).
Improved refrigerated storage and meat ageing are vital to ensuring better meat quality, safety, and shelf life.

The experiment was carried out during the growing season (2023-2024) at a farmer's field in Baweiza / Telkif, northwest of Mosul city, which is located within the Semi-Arid (36°27'17.8"N 43°04'51.9" E). Where the rain amount reached 279 mm. The field soil was characterised as a Silt-Loamy soil texture. A Turkish modern disk grain drill was used in the experiment (Skalak), which is manufactured specifically for conservation agriculture, for seeding wheat grains. The experiment included three factors: the first was soil moisture with two high levels of 23% and an ideal moisture level of 17%; the second was three seeding speeds (8.3, 10.3 and 12 km/h); and the third was seeds coverage tool (with and without press wheels), the experiment was established using a Randomized Complete Block Design (RCBD) under split-split plot system, where the moisture factor occupied main plots, seeding speed was assigned to sub-plots, and sub-sub-plots were used for seeds coverage tool. The Duncan multiple range test compared means at a 0.05 significance level. The following traits were studied: Slippage percentage, soil adhesion strength, actual soil disturbance volume, and grain yield. The important results are that the ideal soil moisture of 17% achieved significant improvements in all studied qualities compared to high soil moisture of 23%. The results also indicated a significant effect at a speed of 12 km/h, where the highest value of slippage, soil disturbance volume, grain yield, and the lowest soil adhesion strength were recorded. The use of press wheels achieved a significant positive difference in soil adhesion strength, while not using press wheels led to a significant improvement in the slippage percentage. The results showed that the triple interaction between moisture content, seeding speed and seed pressure wheels did not significantly differ in the studied characteristics (slippage percentage, actual soil disturbance volume, and grain yield). However, it was found that there was a significant effect in reducing the value of adhesion force at ideal humidity with a speed of 12 km / h using seeds press wheels

Drought is a significant phenomenon associated with climate change, impacting various sectors. Effective planning is essential to mitigate its effects and minimize potential damage. Remote sensing data and GIS-based spatial analysis were employed to assess drought conditions. This study focuses on Sulaymaniyah Province, located in northeastern Iraq, covering an area of 21,240 km². Geographically, the province lies between longitudes 44°49'59" E and 45°59'43" E, and latitudes 34°21'07" N and 36°15'48" N. The study utilized Landsat 8 OLI satellite data to derive two key spectral indices: The Normalized Difference Vegetation Index (NDVI) and the Normalized Difference Water Index (NDWI). These indices were analyzed using ArcGIS 10.4.1 to assess drought conditions and their spatial distribution across the region. Maps highlighting NDVI and NDWI values were created to evaluate the drought impacts for the years 2013, 2017, 2021, and 2022.The findings indicate a clear spatial variation in drought severity across the province. NDVI analysis from 2013 to 2022 shows notable vegetation cover fluctuations, with low vegetation increasing from 43.7% to 66.5% in 2021 and dense vegetation peaking at 11.9% in 2017 before declining sharply. NDWI analysis indicates a rise in extremely drought-affected areas from 17.4% to 34.8%, while no-drought zones decreased from 0.6% to 0.1%. These findings reflect increasing water stress and environmental changes in Sulaymaniyah Governorate. Vegetation density declined after 2017, and drought severity worsened. NDI increased from 0.42 in 2013 to 0.53 in 2022, indicating a growing disparity between plant health and water availability, suggesting worsening drought conditions in Sulaymaniyah Governorate

The present study was conducted at the experimental field site Qlyasan Research Station, situated within the Sulaimani region. This facility serves as the research hub for the Department of Biotechnology and Crop Science, affiliated with the College of Agricultural Engineering Sciences at the University of Sulaimani. A field experiment was conducted in spring during the growing season of (2023) to evaluate the impact of planting date on growth, yield and quality of niger (Guizatia abyssinica Cass.) cultivars The experiment include two factors first was planting dates: (April 1st, April 15th, May 1st and May 15th), while second factor include cultivars (Benglanuglue, Karal and Animax). Results revealed that the longest days to 50% flowering and days to maturity and the highest values plant height, branch number/ plant, capitulum number/ plant, seed number/ capitulum, 1000-seed weight, and seed yield (kg ha-1), seed oil content obtained from crop sown on 1st April as compared to other planting dates. The lowest values of all the mentioned parameters were obtained from the crop sown on 15th May. However, the highest amount of seed protein content was obtained from crops sown on 15th May. Among the cultivars, Benglanuglue performed significantly better than other cultivars and produced the highest seed yield and seed oil content at the 1st April sowing time

This research, conducted at Bakrajo Technical Institute in a multi-span greenhouse during the 2024-2025 growing season, investigates Influence of Irrigation Water Electrical Conductivity EC on Lettuce Growth and Yield, Treatment 1 (EC = 1.6 dS m-1), Treatment 2 (EC = 4.4 dS m-1), Treatment 3 (EC = 3.98 dS m-1), Treatment 4 (EC = 2.67 dS m-1), Treatment 5 (EC = 2.86 dS m-1), and Treatment 6 (EC = 0.750 dS m-1). Experiment design plant height, leaf number, chlorophyll Content change to intensity, fruit change to head diameter, fresh weight, root weight, and dry matter yield. The study reveals a clear negative correlation between higher EC levels and plant development, with lower EC values (0.750 dSm-1) promoting optimal growth across nearly all the measured parameters. Plants exposed to the 0.750 dSm-1 EC level exhibited the highest average values for key growth metrics, including plant height (42.0 cm), leaf number (45), and chlorophyll SPAD readings (87.4), indicating superior growth and photosynthesis. As the EC levels increased, plant performance steadily declined. Specifically, EC values above 2.67 dSm-1 significantly reduced growth indicators, including plant height, leaf number, and head size. This decline in performance is attributed to osmotic stress and nutrient uptake limitations caused by high salinity. The study also found that excessive salinity severely affected other growth parameters, leading to marked reductions in fresh weight, root weight, and dry matter, especially at EC levels of 3.98 dSm-1 and 4.4 dSm-1. Further correlation analysis confirmed strong positive relationships between several growth parameters, such as plant height, number of leaves, and yield. The findings of this study underscore the critical importance of effectively managing irrigation EC levels to maintain plant health and optimize agricultural productivity. It suggests that excessive salinity in irrigation water can hinder plant growth, limit nutrient absorption, and negatively affect overall plant development, highlighting the need for careful monitoring and control of EC in irrigation systems.

The purpose of this research is to identify the level of effectiveness of human resource management practices from the perspective of agricultural extension workers in achieving the objectives of agricultural extension centres in Sulaymaniyah Governorate, as well as to classify the fields of these practices according to their importance, and studying the correlation between them and a group of independent variables. The research population comprised all agricultural extension personnel employed at the extension centres within Sulaymaniyah Governorate, totalling 95 workers in agricultural extension. These workers were distributed throughout the various districts and sub-districts of the governorate; the research findings illustrated that the effectiveness of human resource management practices in agricultural extension centres is low, with a tendency to reach a medium level. Additionally, the research results revealed that planning practice was the highest-ranked discipline compared to other practices. They also findings indicated a correlation between the effectiveness of human resource management practices and certain research variables, specifically (Age, Gender, Duration of agricultural service, Duration of agricultural extension service, Participation in Training courses, and Workplace) However, no correlation was identified concerning other variables, such as (Academic specialisation, Academic achievement, Marital status, Attitude towards human resource management practices, and Sources of agricultural information). Therefore, the researchers recommend enhancing awareness and training on the importance of human resource management and its role in improving productivity and providing the financial and technological resources necessary for effectively implementing these practices within the agricultural extension centres in the governorate

These studies were carried out with the purpose of boosting the efficiency of oil crop production. The purpose of this study was to gain a better understanding of how the use of organic and mineral fertilizers can influence the physical and chemical features of gypsum soils. Compost, manure, and biochar are examples of organic soil additions that may provide an increase in soil porosity, water-holding capacity, soil microbial population, root penetration, and nutrient utilization. These improvements can be accomplished by the application of organic soil amendments. On the other hand, there is the availability of concentrated inorganic fertilizers, which provide a substantial amount of elements such as minerals and vitamins. These fertilizers are composed of nitrogen, phosphorus, and potassium, and their purpose is to improve the quality of crops as well as the vitality of plants. By combining a number of different methods of fertilization, it is possible to successfully lessen the quantity of soil that is compacted and to optimize the efficiency with which nutrients, root conditions, and water regimes are cycled through the plant. Research conducted in the field has shown that the implementation of the strategy leads to an increase in the amount of oil crops that are produced. An increase in oil quality and quantity, as well as an increase in the plant's resistance to abiotic stresses like salt and drought, are the means by which this objective may be attained. According to the findings of this research, the management of gypsum soils should make use of methods that are both effective and environmentally friendly. It also established that the most effective method to attain these aims is to combine organic and mineral fertilisers as the acceptable and practical techniques to promote sustainable agriculture and realise the oil crop production potential on gypsum soils. This was determined by the findings of the study.

This study involved two techniques for transferring important genes related to nitrogen fixation into Bacillus megaterium. Initially, morphological characteristics and molecular properties were analyzed to identify isolated bacteria. This process led to the isolation of Bacillus megaterium, Azotobacter chroococcum, and Rhizobium leguminosarum using a specific growth medium. Morphologically, the results showed that all the bacterial colonies were circular, convex, and smooth. A. chroococcum was creamy color, while B. megaterium and R. leguminosarum appeared white. The application of molecular approaches relied on identifying chromosomal DNA, specifically the nifH1 and nifV genes of A. chroococcum, and the plasmid DNA, including the nodD1 and nodG genes of R. leguminosarum. Additionally, genomic DNA and two primers of B. megaterium were included. The nodD1 and nodG genes were successfully transferred from R. leguminosarum to B. megaterium, resulting in 46 colonies on agar plates of Sperber medium that contained tetracycline and ampicillin as genetic markers. Furthermore, the nifH1 and nifV genes were transferred into the transformant B. megaterium from A. chroococcum via a conjugation mechanism, leading to the growth of 170 colonies on plates of Sperber's agar medium containing erythromycin and ampicillin as genetic markers. To confirm the success of these transfers, molecular analyses were conducted to detect the nodD1 and nodG genes in the transformant B. megaterium, as well as the nifH1 and nifV genes in the conjugant B. megaterium. This was achieved using appropriate primers and PCR conditions for all the genes, followed by gel electrophoresis, demonstrating the successful completion of both techniques

The current experiment was conducted in the poultry field of the department of animal production at the College of Agriculture - University of Kirkuk for the period from 22/2/2024 until 4/4/2024, to study the effect of improving the nutritional value of local sunflower seed meal used in broiler diets by adding a lactic acid bacteria and its effect on production traits. 280 one-day-old, unsexed Rose 308 broiler chicks were randomly distributed into seven treatments, with four replicates for each treatment (ten birds for each replicate). The treatments were as follows: (T1) the control diet without any additives, (T2) 25% of the soybean meal replaced with sunflower meal, (T3) 50% of the soybean meal replaced with sunflower meal, (T4) 75% of the soybean meal replaced with sunflower meal, (T5) 25% of the soybean meal replaced with sunflower meal and the lactic acid bacteria added, (T6) 50% of the soybean meal replaced with sunflower meal with the addition of the lactic acid bacteria and (T7) 75% of the soybean meal with sunflower meal with the addition of the lactic acid bacteria. The results showed Significant differences (P ≥ 0.05) in the treatments (third, fourth, sixth and seventh) in the feed consumption rate and no significant differences in the nutritional treatments (first, second and fifth) in the weight gain rate, and in the cumulative week for the feed conversion treatment, the results showed no significant differences (P ≤ 0.05) between the treatments (third, fourth, sixth and seventh), and as for the carcass weight, the first, second, third, fifth and sixth treatments were significantly superior to the fourth and seventh treatments. The relative weight of the gizzard, the fourth treatment, was significantly superior (P ≤ 0.05) to the rest of the nutritional treatments, unlike the relative weight of the breast, which showed a significant difference (P ≥ 0.05). The results of the study showed that there were no significant differences (P≤0.05) in the relative weight of the liver, heart, thigh, back, wings and neck

This study was conducted on the wild wormwood plant collected from Mount Piramagroon with coordinates 35°46'21.6" N, 45°13'46.7" E and an elevation of 2611 m, Sulaymaniyah, Iraqi Kurdistan, aiming to focus on the phytochemical profiling, antioxidant, and anticancer activities of this plant. The results showed that the methanolic extract of this plant contained total phenols at 61.45 mg GA/g, while total flavonoids reached 32.51 mg rutin/g. The plant extract also contained total glycosides (18.9 mg securidaside/g), total saponins (25.5 mg/g), and total alkaloids (23.5 mg/g). By using advanced HPLC technology, ferulic acid, p-coumaric acid, apigenin, catechin, gallic acid, and kaempferol at concentrations (30.7, 491.3, 307.1, 663.1, 256.5, and 384.1 µg/g), respectively, were detected, with a dominance of catechin, followed by p-coumaric acid. The volatile oil extracted by hydro-distillation, Clevenger apparatus, and GC-MS technology was found to contain 16 active compounds, with the highest concentration being the α-pinene compound at a concentration of 12.33%, followed by myrcene (9.15%). Furthermore, strong antioxidant effects were observed. The IC50 value of the extract was 62 μg/mL compared to 250 μg/mL for ascorbic acid. The results of cytotoxicity testing using the Cell Line technique depicted that the methanolic extract showed a highly significant anticancer activity against MDA-MB231 cells at a concentration of 10000 μg/mL after 72 h of incubation. Based on these comprehensive results, we conclude that there were very high concentrations of active compounds present in the extract of this plant, in addition to its high antioxidant and anti-breast cancer activities, making the plant a promising natural source containing powerful antioxidants and anti-breast cancer agents.

Water samples were taken from 36 wells in agricultural lands in Erbil governorate, Iraqi Kurdistan region. Soil samples were taken from five calcareous and seven gypsiferous soils from different locations in the Erbil and Nineveh governorates. Some of the chemical properties of the studied waters and soils were analyzed. Then, the water types, soil types, ion pairs, and their activities and ionic strengths were calculated. The main results were summarized as follows:
The water of (11, 10, 9, 2, 2, and 2) wells before correcting ion pairs plus activity had (Ca-SO4, Ca-HCO3, Mg-SO4, Mg-HCO3, Na-HCO3, Na-SO4) types, respectively. After correcting ion pairs and activity, the water of (1, 16, 3, 6, 7, and 3) wells had the mentioned types, which means correcting ion pairs and activity had a great impact on changing the water types.
The soil samples represent seven gypsiferous and five calcareous soils, depending on their calcium carbonate and gypsum content. The amount of ion pairs in gypsiferous soils is higher than their amount in calcareous soils. The ratio between ion pairs in gypsiferous to calcareous soil ranged from 0.67 to 3.19. The highest value was recorded for (CaSO4)0, while the lowest value was for (MgHCO3) 0. The series of ion pairs for both gypsiferous and calcareous soils was arranged as [(CaSO4)0, (MgSO4)0, (CaHCO3) +, (MgHCO3)+, (NaSO4)-, (KSO4)-, and (NaHCO3)0]. The dominant ions contributing to ion pair formation are Ca+2 and SO4-2; their highest and lowest values were recorded at Sinu1 and Akri locations, respectively. The highest correlation coefficient value between ionic strength and ion pairs was recorded in gypsiferous soil compared with calcareous soil, with the mean values of correlation coefficient of (r= 0.71** and 0.54*), respectively

This study was conducted in the poultry field of the Animal Production Department, in College of Agriculture, University of Kirkuk, for the period from 1/9/2024 to 24/11/2024 for a period of 84 days, with the aim of studying the effect of using celery seeds as a natural antioxidant with the industrial antioxidant Butylated Hydroxy Toluene (BHT) on the productive and physiological performance of LOHMANN BROWN laying hens. 128 laying hens, 86 weeks of age, were used. The birds were randomly distributed into eight nutritional treatments, with four replicates for each treatment, and each replicate had four hens. The nutritional treatments were as follows: First treatment: Control feed free of celery seed additives and BHT, The second treatment: Adding 100 mg/kg of the synthetic antioxidant BHT, Third treatment: Adding 1% of celery seeds, Fourth treatment: Adding 1.5% of celery seeds, Fifth treatment: Adding 2% of celery seeds, Sixth treatment: Adding 1% of celery seeds with the addition of 100 mg/kg of the synthetic antioxidant BHT, Seventh treatment: Adding 1.5% of celery seeds with the addition 100 mg/kg of the synthetic antioxidant BHT, Eighth treatment: Adding 2% celery seeds with 100 mg/kg of the synthetic antioxidant BHT, At the end of the nutritional study, blood samples were taken from the jugular vein of the 12-weeks-age chickens to conduct chemical blood analyses and some production traits. The results of the study showed a significant superiority (P≤0.05) of the eighth treatment over the control treatment in terms of egg production, egg mass, and feed conversion ratio. As for the blood chemical characteristics, there was a significant improvement (P≤0.05) in the level of glucose (mg/dl), cholesterol (mg/dl), high density lipoproteins mg/dl (HDL) and low density lipoproteins mg/dl (LDL), while there were no significant differences in the concentration of total protein (g/dl) and albumin (g/dl) in blood

This study was conducted at the farm of the College of Agriculture, Department of Animal Production, Kirkuk University, from April 28, 2024, to August 4, 2024, to evaluate the effects of substituting yellow peas with soybean meal on egg quality in laying hens. A total of 140 hens were randomly assigned to seven dietary treatments, with varying inclusion levels of yellow peas (0%, 20%, 40%, and 60%) replacing soybean meal. Enzymes were also included as part of a duplicated treatment design. The experiment followed a completely randomized design, with four replications per treatment, and data were analyzed using ANOVA and Duncan’s multiple range test at P ≤ 0.05. Egg quality parameters, including egg weight, shell thickness, albumen height, yolk color, and Haugh unit, were measured. Results showed significant differences in egg weight during specific weeks but no overall differences among treatments. The egg shape index varied significantly among treatments, with the highest recorded in the soybean meal-based diet. Yolk percentage was highest in the 20% and 40% yellow pea treatments, while albumin percentage was highest in the 60% yellow pea treatment. Eggshell percentage remained unaffected by dietary changes. These findings suggest that yellow peas can partially replace soybean meal in laying hen diets without negatively affecting overall egg quality. However, minor variations in certain parameters indicate potential influences of dietary protein composition and amino acid balance

Palm trees are the most important economic resource for Iraq in the past, which occupied advanced positions in the world in the number of palm trees and date production. However, palm groves have suffered a significant decline in their numbers for many reasons, such as climate change, drought, urban sprawl, neglect, geopolitical events, wars, and pests that affect palm groves. Studies have proven that biological determinants, which include disease and insect infestation, were among the oldest and most influential factors in the spread of palm groves and the decline in their numbers, which were approximately 30 million palm trees and declined to nearly half in the first quarter of this century. The article discussed the most important and most lethal pests in palm orchards, such as Khiyas palm pollen disease, shoot death, frond spotting, rot of the growing top, dobas, myxa, dust mites, and red palm weevil. These pests can lead to the destruction of large numbers of date palms, with infection rates ranging between 30 and 100% when appropriate conditions are provided. Because of its spread. It is concluded that insect pests are the most important biological factors affecting the spread of palm groves, and they cannot be eliminated and the deterioration of palm groves prevented except by developing an integrated control program under the auspices of the relevant state institutions
