type: item
description: Mature leaves fully expanded, undamaged were used in this study for leaf anatomy (blade, midrib and petiole) for 12 taxa of subgenera Prunus and Cerasus (P. cerasifera Ehrh., P. domestica subsp. domestica L., P. domestica subsp. syriaca (Borkh.) Janchen ex Mansfeld, P. domestica subsp. insititia (L.) C. K. Schneid, P. domestica subsp. italica (Borkh.) Gams ex Hegi, P. armeniaca var. armeniaca, P. armeniaca cv. Saeede Meraime, P. microcarpa var. pubescens (Bornm.) Meikle, P. microcarpa var. microcarpa, P. brachypetala (Boiss.) Walp., P. mahaleb L. and P. cerasus L.). Also trichome length and frequency on areole part of leaf blade for each taxon were measured. All taxa were characterized by bifacial mesophylls which consist of palisade parenchyma in the upper side and spongy layer in the lower side. The investigated taxa divided according to the number of palisade parenchyma layers in three groups. The shape of midrib, petiole transverse section and shape of the vascular bundles were important diagnostic values used for identifications of taxa. The leaves of all investigated taxa of subgenera Prunus and Cerasus have unicellular trichomes with different shapes kinds present on leaves blade of all studied taxa. Mostly the trichomes in abaxial side areole longer than the trichomes in the adaxial side, also the frequency of trichoms in the abaxial face was significantly higher than in the adaxial face.

PHYTO-SYNTHESIS OF CdO NPs BY CRUDE EXTRACT OF POLYGONUM MULTIFORUM
type: item
description: The goal of this research is to detect flavonoids in Polygonum multiforum and use these extracts in the phyto-synthesis of (CdO NPs) Nano-particles (CdO, CdO2) and characterize them. The HPLC examination yielded five compounds: Emodin (29.55%), followed by Aloe-emodin (24.52%), Chrysophanol (19.24%), Rhein (16.61%), and Physcion (10.06%). Two techniques were utilized to synthesize NPs, and the average size (by AFM) was (83.26 and 86.14) nm for the first and second procedures, respectively. SEM analysis revealed that process 1 produced Nano-rod particles with diameters ranging from (20-50) nm, whereas procedure 2 produced hexagonal Nano-plate crystals with a single Nano-scale size (20-100) nm. TEM pictures showed the same characteristics. For processes 1 and 2, the FTIR analysis showed prominent bands at 524 and 532.4 (1/cm), respectively. This was ascribed to stretching vibrations in Cd-O.

ECONOMIC ANALYSIS OF THE IMPACT OF ECONOMIC VARIABLES ON AGRICULTURAL INVESTMENT IN IRAQ FOR THE PERIOD 1990-2020
type: item
description: This research aimed to study the effect of some economic variables (agricultural output, interest rate, agricultural exports, and imports) in determining the volume of agricultural investment in Iraq during the period (1990-2020) by conducting a dynamic econometric analysis of the data collected from its secondary sources. The Error Correction Model (ECM) was employed, and the statistical analysis was performed using EViews 12 software. The results revealed a positive and significant long-term relationship between the explanatory variables and the dependent variable, agricultural investment. Its equilibrium value in the long term is one unit, and 7% of the divergence from the equilibrium between the long term and the short term can be adjusted during the same period. The agricultural domestic product and agricultural exports for the previous year have a significant positive effect on agricultural investments, whereas agricultural imports have a negative sign. There is no effect of the interest rate on agricultural investments. The results also showed that there were no structural changes in the model variables during the study period.

AN ECONOMIC ANALYSIS OF THE ROLE OF RURAL WOMEN IN IMPROVING FARM INCOME AND LIVING STANDARDS.
type: item
description: This study aimed to determine the contribution of women in diversifying sources of farm income, thereby improving the standard of living of the rural family, through their work in various primary and secondary agricultural production activities. Rural women in Iraq constitute a large part of the family's farm work. In addition to her paid work on other farms. Despite the significant role of rural women's contribution to production processes. However, the percentage of their participation in some agricultural operations is less than that of men due to their limited control over production and marketing decisions. This is reflected negatively in their ability to generate income. The research used cross-sectional data for a random sample that included (384) women from separate rural areas in Baghdad governorate to determine the effect of the working hours of women and men in addition to the number of animals owned by women on the size of the total farm income through the use of the OLS model, the ordinary least squares method with the double logarithmic formula. The results showed that increasing the number of working hours for women positively affects the increase in farm income. Moreover, the size of the parameters of women's work in animal production activity (0.16) and industry (0.15) were more influential than men's work (0.08(. As for the plant production side (0.26), its effect was less than that of men due to the existence of some activities that are specific to women rather than to men. Therefore, the research recommends the need for programs related to developing the skills of rural women in all agricultural activities, providing health and educational care for women, and empowering women financially and technically to increase their contribution to income generation and improve the standard of living for the family.

EVALUATING SLOW RELEASE FERTILIZER PREPARED BY LOADING PHOSPHORUS ON SURFACE MODIFIED NANO SYRIAN ZEOLITIC TUFF
type: item
description: This study was aimed to assessment of using nano Syrian zeolitic tuff (NSZT) as carrier to produce slow release phosphate fertilizer was executed. phosphate salt was loaded to modified nano-zeolite by HDTMA-Br (hexadecyl trimethyl ammonium bromide) surfactant application. Two main treatments (SMZ1, SMZ2), making approximately monolayer (83%) and bilayer (190%) real coverage of external cationic exchange capacity respectively. Phosphate was loaded on SMZ to prepare slow release fertilizer (SRF1, SRF2) respectively. Surface characteristics were conducted by using XRD and SEM techniques. Adsorption/ release experiments and incubation column were studied. Results showed that Langmuir isotherm was better to give good estimation of phosphorus sorption about nature of homogeneity. Phosphate release time into water solution from SRFs increased as surface modification ratio increased. Elovich model was good tool to predict the phosphate release ratio coefficient which was independent of HDTMA-Br modification coverage ratio. After 40 days of incubation experiment in columns, soil effect dropped up the leached phosphate in the flux less than 10% of the initial P loading concentration. Incubation column experiment confirms expectations about the anion exchange mechanism between phosphate and bilayer on NSZT.

BIOCHAR-SUPPLEMENTED IN VITRO CULTURE OF MUSA ACUMINATA VAR. BARANGAN TO CONTROL CONTAMINATION AND ENHANCE REGENERATION
type: item
description: This study aimed to evaluate the effectiveness of coconut shell-derived biochar supplementation in Murashige and Skoog (MS) medium to suppress contamination and enhance regeneration efficiency. A Completely Randomized Design (CRD) with 11 biochar concentrations (0–5 g/L) was used, each with three replicates. Parameters observed included contamination and browning onset, browning intensity, propagule formation time, fresh weight, shoot number, and shoot height. Results showed that biochar significantly delayed contamination and browning. The 2 g/L treatment yielded the best results: 13.8 days after culture (DAC) for contamination and 12.67 DAC for browning. The lowest browning intensity (score 1.41) occurred at 5 g/L. Propagule formation was fastest at 3 g/L, while optimal shoot multiplication and height were observed at 2 g/L. These benefits are attributed to biochar’s ability to enhance nutrient availability, adsorb phenolics, stabilize pH, and regulate endogenous hormones. However, concentrations ≥4 g/L reduced culture performance, likely due to osmotic stress and media imbalance.

DISTRIBUTION OF CLICK BEETLES AND THE DEVELOPMENT OF CONTROL MEASURES IN POTATO FIELDS OF THE REPUBLIC OF ARMENIA
type: item
description: The studies were conducted at the Aragatsotn region of the Republic of Armenia during the years 2021-2024. Four species of click beetles (family Elateridae) belonging to the order Coleoptera of the class Insecta were recorded. The most widespread species was the sowing click beetle (Agriotes sputator L.), making up 56%. The steppe click beetles (Agriotes gurgistanus Fald.) accounted for 25% of the total population. The striped (Agriotes lineatus L.) and dark (Agriotes obscurus L.) click beetles were relatively less common, constituting 14% and 5%, respectively. Based on the analysis of the damage caused by wireworms to the tubers of different potato varieties it can be concluded that the Impala and Arizona varieties are more resistant to the phytophagous pest. These varieties are recommended for cultivation in potato farms. Nuprid (0.2 L/t), Kruiser (0.2 L/t), and Force (15 kg/ha) demonstrate high biological efficacy against wireworms, showing effectiveness comparable to the standard variant, Prestige (1.0 L/t).

type: item
description: This study was aimed to detect the phzS and phzM genes in Pseudomonas aeruginosa clinical isolates that form pyocyanin and resist antibiotics. The study was conducted by collecting 240 samples from different clinical sources (burns, wounds, urinary tract, and ear infections) at Medicine City laboratories Baghdad-Iraq. Only 140 samples were diagnosed as P. aeruginosa, with the major identification depending on morphological characteristics, biochemical tests, the Vitek 2 compact system, and molecular detection of the 16S rRNA gene responsible for this bacterium. Identified isolates were investigated for hemolysin, protease enzymes, and pyocyanin production. The genes phzS and phzM, involved in pyocyanin production, were investigated, and the isolates' sensitivity to 12 antibiotics was also tested. The results showed that all the isolates were able to produce hemolysin, 80% of the isolates were protease enzyme producers, and 72.15% produced pyocyanin. The presence percentage of the phzS gene (90%) was higher than that of the phzM gene (70%), and only the isolates that possessed the two genes producing pyocyanin, while those that contained one of the genes phzS or phzM did not. The highest levels of antibiotic resistance were for colistin (100%) and ceftazidime (97.14%), while the least were for imipenem (26.42%) and piperacillin-tazobactam (22.85%). The isolates producing pyocyanin are more resistant to antibiotics than those unable to produce it.

MONITORING AGRICULTURAL DROUGHT IN REGIONS OF IRAQ USING REMOTE SENSING TECHNIQUE
type: item
description: The phenomenon of drought is one of the most significant environmental and climatic extreme events; it is more complex in terms of measuring, monitoring, and identifying the possible effects and hazards associated. The remote sensing index, which included the Vegetation Health Index (VHI), was used to describe the geographic and temporal distribution of the springtime agricultural drought. VHI can be calculated based on the Temperature Condition Index (TCI), Vegetation Condition Index (VCI), and Normalized Difference Vegetation Index (NDVI) derived from MODIS Terra satellite data. The outcomes showed that the droughts in the years 2001–2002, 2008–2009 were the most extreme in twenty-two years. The drought years 2001-2002 were followed by the drought-free years 2002/2003,2008/2009. The years 2017-2018 show this phenomenon distributed mostly in the south and southwest bearing. According to the findings, the southwest and western regions are more vulnerable to drought. The results of the drought index VHI indicate that the country is facing non-uniform cycles of drought for all types of droughts. Also, the results showed that there is a negative significance between rainfall and extreme, severe, and moderate drought, even if there was no substantial negative link between rainfall and dryness. It is recommended to adopt the VHI index to monitor the desiccation of vegetation in semi-arid areas with little access to surface meteorological information.

EFFECT OF BIRTH NUMBERS AND PREGNANCY PERIODS ON SOME BLOOD PARAMETERES OF AWASSI EWES
type: item
description: This study was conducted to investigate the effects of birth number, pregnancy stage (pre- and post-pregnancy), and their interaction on selected blood parameters in local Awassi ewes under grazing conditions. The experiment involved 33 local Awassi ewes, divided equally into three groups: the first group consisted of ewe lambs, the second group included ewes with one previous birth, and the third group comprised ewes with multiple births (2–3). Birth number showed no significant effect on any of the blood parameters. However, mean corpuscular hemoglobin concentration (MCHC), hemoglobin (Hb), and packed cell volume (PCV) were significantly higher at mid-pregnancy (12th week) compared with the 4th and 20th weeks of pregnancy. Serum total protein and cholesterol levels were significantly higher (P ≤ 0.01) during the pre-pregnancy period compared with other stages. Serum calcium levels were significantly higher (P ≤ 0.01) during the pre-pregnancy period and at the 4th week of pregnancy compared with the other stages. Phosphorus concentrations increased significantly (P ≤ 0.01) at the 4th week of pregnancy compared with all other study periods. However, no significant interactions were observed between birth number and pregnancy stage. In conclusion, the pre-pregnancy period had a critical impact on certain blood parameters of local Awassi ewes.

EFFECTIVENESS OF MARINE FUNGI AS FEED ADDITIVE ON NATIVE CHICKEN PERFORMANCE
type: item
description: This study was conducted to determine the effectiveness of marine fungi as a feed additive on the performance of native chickens. One hundred and eighty unsex one-day-old native chickens were used in this study. Chickens were kept for ten weeks and given a treatment supplemented with the dietary marine fungi (1, 2, 3, and 4 ml/kg) in a ration consisting of yellow corn, rice bran, fish meal, soybean meal, coconut meal, L-lysine, methionine, and CaCO3. The data collected were feed consumption, body weight gain, carcass percentage, mortality rate, and feed efficiency. The results showed significant (P<0.05) decreased feed consumption and increased mortality with adding marine fungi. They did not affect the body weight, carcass percentage, and feed efficiency. The highest mortality occurred in a group of chickens supplemented with marine fungi as much as 3 ml/kg. It was concluded that marine fungi could be added to the ration as much as 1 ml/kg from the beginning of keeping to improve the performance of native chickens effectively and increase the chicken’s immunity. It is suggested to mix marine fungi extract into the drinking water. Thus, its active compounds might be absorbed more effectively to improve the performance and produce healthy poultry products.
