As the rarest agricultural input, water has increased its productivity over the last few decades. Surveys based on the amount of virtual water and water productivity indicators in agricultural crops, we need to examine the relationships that indicate the actual amount of water consumption for crop production. The present study, virtual water content of selected crops (Wheat, Barley, Chickpea, Sugar beet, Potato, Tomato, Cucumber, Alfalfa and Clover) examined in Saqqez city of Kurdistan province using three indices of physical and economic productivity of water including CPD, BPD and NBPD in the year 2015-16. The results of CPD index for Sugar beet and chickpea products were 9.5 and 0.2 kg / m3 with the highest and lowest values, respectively. Also, the results of BPD, and NBPD for Potato and Tomato products were about 3900 and 395 Toman per cubic meter respectively, and the NBPD index of 1420 and -110 Toman per cubic meter had the highest and the lowest values respectively. Other results of the research on the amount of virtual water showed that the chickpea product with 4.2 m3 / kg virtual water had the highest level of virtual water, which is also the lowest virtual water productivity in this product. In contrast, the index for sugar beet at 10 kg / m3 has the highest amount of virtual water productivity in the study area
