dc.description.abstractPerformance evaluation of a tractor operated air assisted orchard sprayer had been undertaken. Hollow cone nozzles and double action nozzles were used to study the performance of the sprayer. The sprayer was tested in laboratory at four operating pressures (3, 4, 6 and 8 kg/cm2) and three blower speeds (1288, 1883 and 2541 rpm) to determine the suitable operational parameters for the sprayer. The combination of 8 kg/cm² pressure and 1288 rpm blower speed was found to be the suitable combination which was selected for field test. Sprayer was operated in the field at three forward speeds (0.76, 1.09 and 1.64 km/h), and different parameters were recorded and analyzed. Volume median diameter and uniformity coefficient for hollow cone nozzles varied from 162 to 300 µm and 1.62 to 2.88 respectively and for double action nozzles, it varied from 127 to 166 µm and 1.29 to 2.34 respectively. The droplet density on upper and underside of leaves for hollow cone nozzles varied from 43 to 178 and 69 to 301 drops/cm2 respectively and for double action nozzles, it varied from 72 to 203 and 51 to 98 drops/cm2 respectively. Volume of spray deposition on upper and underside of leaves for hollow cone nozzles varied from 107.4 × 10-6 to 383.79 × 10-6 cc/cm2 and 100.59 × 10-6 to 781.93 × 10-6 cc/cm2 respectively and for double action nozzles, it varied from 120.23 × 10-6 to 216.05 × 10-6 cc/cm2 and 54.76 × 10-6 to 172.15 × 10-6 cc/cm2 respectively.en_US
