Abstract
The irrigation properties of the Voghji and its main tributaries – Artsvanik and Geghi rivers and their agricultural risks according to the content of some heavy metals and dissolved mineral salts were investigated. Water sampling was implemented in irrigation period (July) of 2016. The results of the study showed that waters in the Voghji river site located in the downstream from Kapan town and in the area of the Artsvanik river mouth, according to molybdenum, manganese, iron and sulfate contents, were unallowable for the use for irrigation purpose and may pose agricultural risks.
