The study included measurements of the vertical distribution of spray for two different ways of nozzles setting, two types of nozzles and two fan rotation speeds. The vertical distribution of spray depended significantly on spray emission system, the configuration and the type of nozzles and in the slightest degree on the fan rotation speed. The smallest share of liquid fell on the edge segments (≤ 5.22%) and the largest on the middle ones – 29.33%. The change in the configuration of nozzles significantly affected the change in the spray vertical distribution (by the spray displacement between the 50-cm segments). The greatest changes in the vertical distribution of spray – as affected by nozzle configuration change – was observed for the sprayer with the horizontal spray emission with maximum change in one segment of 14.0% (an average of 7 segments: 5.38%).
