The avoidance of failure in construction projects is not an easy task, which makes the failure of the construction project to achieve its objectives a major problem experienced by all countries in the world, especially Iraq. Where nearly two-thirds of the construction projects in the world have been suffered by significant problems as an increase in the cost of the project, delay in the specified duration for execution, and stopping the project. Therefore it is required to study and apply new methods for managing the construction project to ensure its success and achieve its objectives. The aim of this study is to study the Agile project management method and its impact on the construction project. In addition, to identify the values and principles of Agile project management, which can be applied in the Iraqi construction industry to be adopted it as a new method to manage the construction projects in Iraq. The researcher reviewed the relevant literature to define the method of Agile project management and its methods and impact on the construction project. Then, the researcher conducted a questionnaire survey of a sample of engineers' experts who work in four main parties in the construction project: (beneficiary, supervising, designer, and contractor). The results of this survey showed that it is possible to apply the four values of Agile project management for managing the Iraqi construction projects, and can apply eleven of the twelve principles of Agile project management for managing the Iraqi construction projects.

A field experiment was carried out to evaluate the effect of different irrigation systems on some soil physical properties, growth and yield of cotton crop in one of the experimental fields of the College of Agricultural Engineering Sciences, University of Baghdad in Jadiriyah / Baghdad in a sandy loam soil for the spring agricultural season 2021. Irrigation systems included surface drip irrigation, subsurface drip irrigation and furrow Irrigation systems as a control treatment were studied in this experiment. Soil moisture content, soil bulk density, soil moisture homogeneity coefficient, plant height and plant yield were measured in this study. Nested design was used under randomized complete block design (RCBD) with three replications. The superiority of the subsurface drip irrigation system (LSD = 0.05) in obtaining the highest soil moisture content stood 15.01%, the lowest soil bulk density stood 1.28 g cm -3 , the highest soil homogeneous Humidity Factor stood 95.73%, the highest plant height stood 121.75 cm, and the highest number of boll branches stood 13.10 branches plant -1 and the highest yield stood 141.98 g plant -1 Compared with surface drip irrigation system. Furrow irrigation excelled in obtaining the highest soil moisture content stood 20.51%, the highest plant height reaching 135.50 cm, and the highest number of boll branches reached 16.79 branches plant -1 and the highest yield reaching 196.125 g plant -1 . Results obtained of this study improved our understanding regarding irrigation of cotton crop under arid and semi-arid conditions
