This work presents the methodological steps of calculating the basic indices of economical effectiveness of irrigation technologies. Cost was divided into fixed and variable costs. The results from calculation of the irrigation cost of irrigation sprinklers Nettuno, Odra, Maya, R. Bauer and Sigmat are given. In terms of the efficiency cost and the need for labour, an R. Bauer sprinkler, model 110/300, was found to be the most advantageous.
