The subject of the performed experiments comprised standard RSMM 110-02, RSMM 110-02 nozzles, AI 110-02, AI 110-02 air induction nozzles as well as AZMM 110-02, AZMM 110-03 low drift nozzles. The working speed during spraying was vp = 7 km/h. Each sprayer was tested at the following three levels of working pressures: p1 = 0.2 MPa, p2 = 0.4 MPa and 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 of the leaf
The purpose of applying an additional air flux in field sprayers is limiting liquid drift. The tlux also influences the quality of plant spraying. Air Plus Spridotrain sprayer, produced by RAU company, was applied in the research on the influence of air flux on the quality of coverage of winter wheat (Roma variety). The plant coverage was determined using water sensitive papers.
