Corrosion Resistance Enhancement for low carbon steel is very important to extend its life service, the coating process is one of the methods which can using to achieve this, and it's the most important in surface treatments to improve the properties of metals and alloys surfaces such as corrosion resistance. In this work, low carbon steel was nitrided and coated with nano zinc using gas phase coating technical, to enhance the resistance of corrosion. The process included adding two layers. The first, a nitride layer, was added by precipitating nitrogen (N) gas, and the second, a zinc (Zn) layer, was added by precipitating Zn. The process of precipitating was carried out at different periods (5, 10, and 15 minutes). Scan electron mi

The study was conducted at the fields of the Dept. of Horticulture and Garden Engineering, College of the Agricultural Engineering Sciences, Jadriyah in the fall season of 2020-2021 aiming to culture the coral lettuce with green and red leaves under the hydroponics system using the modified nutrient solution film NFT and study the effect of aqueous extracts of alfalfa and berseem sprouted seeds on the quantitative and qualitative yield of the lettuce crop. The research was conducted as an experiment of split plots within the Randomized Complete Block Design (RCBD) of three replicates. The seedlings of the green coral lettuce, Locarno RZ, and red coral lettuce, Locarno RZ, symbolized by A and B respectively, were transferred to the c

The Umm Al-Naaj Marsh was chosen in Maysan province, and it is one of the sections of Mar Al-Hawza, which is one of the most prominent Iraqi marshes in the south. The marshes are located between latitudes 30 35 and 32 45 latitudes and longitudes 13 46 and 48 00. The area of the study area is 76479.432142 hectares to evaluate soil quality and health index and their spatial distribution based on measuring physical, chemical, biological and fertility traits and calculating the total quality index for those characteristics. Using an auger drilling machine, we collected 50 randomly selected surface samples, evenly distributed across the study region, from Al-Aq 0.0–0.30 m, noting their precise locations along the way. Soil health and quality w

This study was aimed to estimate the influence of Conocarpus erectus L. residues, and some micronutrients on growth and production of potato. This research was conducted at one of the fields of the College of Agricultural Engineering Sciences - University of Baghdad. The experiment was implemented using factorial arrangement (4X3X3) within randomized complete block design with three replicates. Conocarpus fertilizer was represented the first factor with three levels (7.5, 15, 30 ton.ha-1), which symbolized (C2, C3, C4). Mineral fertilizer as recommended dose as a control, which symbolized (C1). The second factor was foliar spraying with three levels of iron (0, 100, 200 mg.L-1), which symbolized (F0, F1, F2). The third factor is fol

This experiment was carried out at a private field in the eastern Radwaniyah Baghdad for the fall season 2020/2021 and spring 2021 to study the effects of adding mineral fertilizers, spraying salicylic acid and amino acids on some growth traits and yield of industrial potato plants. 200 kg N h-1 , 100 kg P2O5 h-1, 100 kg K2O h-1 and F2 consist of 275 kg N h-1, 180 kg P2O5 h-1, 200 K2O h-1 and F3 consist of 350 kg N h-1, 360 kg P2O5 h-1, 300 K2O h-1 and salicylic acid in three concentrations of 0,50 and 100 mg L-1 ( S1, S2, S3) and amino acids in three concentrations of 0, 1.25 and 2.5 ml L-1 ( A1, A2 , A3) It was carried out as a factorial split plot experiment, where the fertilizer levels (F1, F2 and F3) are in the main plot and th

In this study, functional and numerical response tests, which are important components in the selection of biological control agent, were carried out. In functional response trials, the amount of food consumed, attack rate (a) and handling time (Th) were calculated for each developmental period, depending on the number of preys given after 24 hours. The obtained results were evaluated with the Holling. In numerical response experiments, the development of the predator insect was examined depending on the number of preys given in certain numbers (5, 10, 20, 40 and 80) and the data were recorded. This phase of the trials continued until the individuals died. At this stage of the trials, the reproductive response of the p

This study was aimed to investigate the appropriate planting date and tolerance to adverse growing conditions in the spring season through seeds stimulation technology. A field experiment was carried out in the spring seasons of 2022 and 2023 according to a randomized complete block design in a split-plot arrangement with four replications. The main factor is planting dates (February 15^th, March 1^st and 15^th, and April 1^st and 15^th). The secondary factor is seeds stimulation (potassium nitrate 6 mg L^-1 + licorice extract 6 g L^-1, as well as soaking with distilled water only). The stimulated seeds (potassium nitrate + licorice extract) and the planting da

An experiment was conducted at the central lab of Graduate studies - College of Agriculture, University of Baghdad during 2015-2016. The objective was to study the effect of growth regulator on inducing callus from embryos of two alfalfa cultivars (PAC-78001 and local) variety by tissue culture technique using factorial experiments according to CRD. Seeds sterilized by NaOCl at 4.5% for 15 minutes, then, cultured on MS media free of growth regulators to embryo induced. The embryos were cultured on MS media at different concentrations of 2,4-D (0, 1, 2, 3 and 4) mg Li^-1. Induced callus from embryos was cultured on MS media supplementing with Kin. at 0, 0.25, 0.50, 0.75 and 1 mg Li^-1 to determ

Field experiment was conducted out Al-Anbar in winter season of 2011/2012 to investigate decision making of selection to the genotypes of caraway Carum carvi L. thus, to introduce in consequent breeding program and test effectiveness of GT Biplot and two model of multi-trait selection, master and against checks jointly in GGE Biplot software for seven genotypes by six traits of caraway. Genotypes were randomly distributed underwith RCBD design with three replicates. Results revealed that these techniques were effective to derived information from data. Where, GT Biplot extracted 92.6% of total variation. Furthermore, it was indicated that was significant association between plant height and umbellets no. which those trai

The aim of this work was to check the presence of the dumping from neighboring countries of Iraq, Turkey and Jordan. The margin of dumping was calculated by taking the difference between the normal value and the export price. If it exceeds 2%, then there is dumping. Product dumping in Iraq has increased since 2003, and it is increasing from year to year for many types of agricultural and food commodities. Main reasons are the high rate of imports and the absence of trade policies represented by customs tariffs which in turn control the trade exchange. The research concluded that there is an intentional dumping in the trade of some agricultural commodities with Iraq from neighboring countries. Trade exchange with these countries h
