Droplet size statistical analysis in chemical crop protection with unmanned aerial vehicle

The development of modern technologies in agriculture, particularly the use of unmanned aerial vehicles (UA Vs), has enabled significant advancements in pesticide application, resulting in greater efficiency and precision in crop protection. This study aims to analyze the effects of various UA V flight parameters, specifically flight altitude, on droplet size and distribution uniformity. Field trials were conducted on the municipality of Zemun-Belgrade, Republic of Serbia, Latitude: North 44° 49' 22.2" and Longitude: East 20° 13' 19,2", with an altitude of 73 m. Different flight heights (1.5 m and 2.5 m) were tested at a constant flight speed of 3 m/s. The results indicated that smaller droplets, generated at higher flight altitudes, contributed to more uniform droplet distribution, while larger droplets at lower flight altitudes ensured better coverage. The most favorable outcomes were observed at a flight altitude of 2,5 m, where droplet distribution was both more uniform and of higher quality.
