Abstract:
Droplet size analysis of orchard sprayer having axial flow blower was carried out to determine the changes in droplet size at different speed and different blade angles. Droplet size analysis was carried out at two different positions (Outer and Inner) of crop canopy and at three different heights (Top, Middle, Bottom) of each crop canopy. The minimum value of droplet size at outer canopy and at top position was measured 117.4 µm at blade angle 40˚ and speed of operation 3.5 km/h. Whereas, the maximum value was recorded 207.9 µm at blade angle 25˚ and speed of operation 2.5 km/h. At middle position (Outer canopy) the minimum value of droplet size was recorded 126.0 µm as an effect of blade angle 40˚ and speed 3.5 km/h and maximum value 214.4 µm as an effect of blade angle 25˚ and speed 2.5 km / h. At bottom position (Outer Canopy) the minimum value of droplet size 137.6 µm was obtained as an effect of blade angle 40˚ and speed 3.5 km/h. Whereas, the maximum value was observed 226.0 µm at blade angle 25˚ and speed of operation 2.5 km/h. The minimum value of droplet size at inner canopy and at top position was found to be 109.0 µm at blade angle 40˚ and speed of operation 3.5 km/h whereas the maximum value of droplet size was recorded 198.5 µm at blade angle 25˚ and speed of operation 2.5 km/h. At middle position (Inner canopy)the minimum value of droplet size was measured 116.9 µm as an effect of blade angle 40˚ and speed 3.5 km/h and maximum value 205.3 µm as an effect of blade angle 25˚ and speed 2.5 km / h. At bottom position the minimum value of droplet size 131.1 µm was obtained as a effect of blade angle 40˚ and speed 3.5 km/h. Whereas, the maximum value was observed 219.1 µm at blade angle 25˚ and speed of operation 2.5 km/h.
