    Abstract

    Effect of sprayer bounce and wind velocity on spray pattern displacement (SPD) of two agricultural nozzles were studied using an experimental spray patternator. Tests were conducted at a nozzle pressure of 207 kPa at two wind conditions (C, crosswind velocity of 2.68 m/s; and CH, combination of crosswind velocity and headwind velocity of 2.63 m/s) and at two sprayer bounces (0.2 and 0.4 m amplitude at a frequency of 1 Hz).

    Sprayer bounce × wind velocity had significant effect on the SPD values. For both the nozzles, the SPD value for sprayer bounce (0.4 m amplitude) × crosswind velocity × headwind velocity was higher by at least 5 percentage points than that for sprayer bounce (0.4 m amplitude) × crosswind.
