In India, although air-assisted spraying technique has been employed in some of the hand operated and boom sprayers, air-carrier sprayers capable of spraying vast orchard and tree crops are still aliens to Indian agriculture. As the name implies, an air-assisted sprayer utilizes an air stream to carry the spray droplets onto the target It employs a blower (which is basically a fan) to produce and deliver an air stream of sufficient discharge, velocity and pressure, and introduces the spray fluid into this air stream in the form of fine droplets at high pressures (from a reciprocating pump) at the air outlet. The study has been carried out on the parameter viz., blade angle (25?, 30?, 35?, 40?) and blade type (blade 1 and blade 2) which was affecting the droplet size and droplet density of spray. The minimum value of droplet size at outer canopy (134.7 µm) and inner canopy (126.9 µm) was observed at top position at blade angle 40? while the maximum value of droplet size at outer canopy (209.1 µm) and inner canopy (201.5 µm) was observed at bottom position at blade angle 25?. The minimum value of droplet density at outer canopy (27.6) and inner canopy (32.1) was observed at bottom position at blade angle 25? while the maximum value of droplet density at outer canopy (68.0) and inner canopy (72.8) was observed at top position at blade angle 40?. It was found that as the blade type changes from blade type 1 to blade type 2 droplet density increases while droplet size decreases.
