Description
Summary:When developing agricultural sprayers, it is desirable to follow measures and procedures that would result in minimal impacts on the ecosystem. With the technical perfection of the machine for plant protection, it is especially important to adjust the technical parameters of application of pesticides - working speed, working pressure, air flow and speed, spraying norm, type of sprayer, etc. The aim of the research is to define the jet geometry in accordance with the average canopy geometry, with the task of increasing the efficiency of the application by adjusting the parameters to the treatment conditions. The result is a reduction in the risk of environmental impact, through a reduction in losses. The norm of 530 l/ha, achieved a slightly higher coverage on the target area of 56.27% on the left side, while the right side is slightly less covered with 46.08% coverage. The highest norm in the research was 650 l/ha with an average coverage of 56.28%, ie a coverage of 64.48% on the left side and 48.09% on the right side of the unit.
