Flight Operational Parameters of Drone with Atomization as Components of Optimum Spray in Corn

This study used a 4 × 2 factorial design with four blocks, consisting of the following speeds: 16, 20, 24, and 28 km/h (factor 1) at flight heights of 4 and 5 m (factor 2) above the plant canopy. Water-sensitive paper was affixed to the upper third of the corn plants at the V8 stage.
