This paper analyzes the success of the project "IRRI - Irrigation Project". On the territory of the Republic of Croatia over the past few years, large droughts have been recorded that negatively affect agricultural production decreasing yields. Manufacturers therefore lose the capability of further investment in increasing production or investing in new technologies. With this project has been proven that with the help of EU funds, it is possible to receive support for investment in irrigation, which will prevent the huge loss of cultures necessary for agricultural production during the dry season. With a help of 17 demonstration fields set up in the municipalities of Lovas and Tompojevci in the Republic of Croatia, and in the municipalities of Odžak and Šamac in Bosnia and Herzegovina, increased agricultural production was provided and they serve as a guideline for other producers to successfully maintain agricultural production. With this work will be show which all procedures and processes should be carried out in order for the project to be successful and then eventually be 3 released in function. Given that theproject was completed in 2014, the aim of the work was to find out how much the project has met and meet the expectations of all the participants through the collected data and surveys.
