TY - JOUR N2 - The subject of the performed experiments comprised standard XR 110 02, XR 110 04 nozzles, TT 110 02, TT 110 04 nozzles and AI 110 02, AI 110 04 air induction nozzles. The working speed of spraying was vp = 7 km/h. Each nozzle was tested at the following three levels of working pressures: p1 = 0.2 MPa, p2 = 0.4 MPa ad p3 = 0.6 MPa. The spray liquid was pure water at the temperature of 20°C. The plant coverage was determined: sk – spray coverage, nk – number of droplets per 1 cm2. The analysis of results of maize spraying showed that both standard nozzles and both TT nozzles achieved better results with number of droplets and degree of surface coverage for each of applied operating pressure. The lowest results from all examined kind of nozzles for number of droplets achieved injector nozzles (AI). For operating pressure 0.4 MPa nozzles fulfilled agrotechnical requirements for using insecticids, herbicides and fungicides.
