In the assessment of the quality of treatment using the application indicator there is no information concerning the parametric characteristics of the sprayed plant. Therefore, the aim of this study was to determine the application of the utility liquid depending on the coefficient of the position of the spray surfaces with the use of the selected single- and dual- spray nozzles. The studies were performed at the Institute of Agricultural Engineering of the University of Environmental and Life Sciences in Wroclaw, in laboratory conditions. The carrier of nozzles acting as an independent sprayer was used for spraying. The coefficient of the position of the spray surfaces as the relation of surfaces of vertical projections and to the surfaces of horizontal projections was determined using artificial plants by appropriately setting its sprayed surfaces. Results of the tests and their analysis showed the influence of the position of spray surfaces coefficient on the deposit of the spray liquid.
