This paper presents a review of works on effective water use, which have been completed or not from 1985 to November 2003, and aims to determine the priority research topics in the South-Eastern Anatolia Project (SEAP) Areas. The information and relevant data from existing papers, articles and some scientific catalogues were collected and analysed. The number of completed researches from 1985 until November 2003 is 90 except the works on the participatory irrigation management. Most of studies (87percent) are completed, and approximately 72percent were on the subjects related to the crops and irrigation management. Among these studies, 61 percent (44percent of total) includes subjects on full and limited irrigation and 29 percent (21percent of total) involves crop-atmosphere relationships. The greatest number of studies has been conducted in 1996 and 2003, corresponding to 14 percent of the total in each year. Most of the studies are a replicate of each other. The studies were supported only by the state institutions.
