Abstract
This study investigated the potential of a hexacopter unmanned aerial vehicle (UAV) spraying system as one of the agricultural spraying methods in Malaysia. The altitude of the UAV he operated at 1.5 meters and under a wind speed of 1.15 meters per second he tested three different nozzles. The uniformity and spread of application in paddy field conditions were evaluated. ImageJ software was used for evaluation. The results showed that using an electrostatic centrifugal nozzle for droplet dispersion resulted in remarkable average droplet densities, especially 134.03 deposits/cm2 in the upper region and 153.93 deposits/cm2 in the lower region. Furthermore, in the electrostatic centrifugal nozzle, it was confirmed that 3478 droplets were deposited in the upper region and 3255 droplets were deposited in the lower region.
