Application of pesticide and insecticide is important for minimising biotic stress and increasing of food production. Application of pesticides is mainly accomplished by hydraulic energy nozzles sprayer.For applying insecticide and fungicide the complete coverage on leaf surface of crop hollow cone hydraulic nozzles are used. Three commercially available hydraulic hollow cone nozzles N1, N2 and N3 (Aspee 80/450, Aspee 100/700 and Aspee 100/900; respectively) suitable for agricultural spraying were selected and studied for different spray characteristics such as discharge rate, swath width, spray angle and spray distribution pattern for different pressure. A standard horizontal spray patternator was used for measuring spray distribution pattern for selected nozzles.In this study, results showed that nozzle N3 give maximum discharge (1320 ml/min) followed by N2 (1128 ml/min) and N1 (868 ml/min) 4 kg/cm2pressure. The minimum spray volume was collected at the outer edges while it increased towards the centre of the nozzle. The swath width of nozzle N1, N2 and N3 was increased from 44 to 60 cm, 62 to 73 and 67 to 88 as pressure increased from1to 4 kg/cm2respectively.Increase in spray angle from 52° to 68°, 69° to 78° and 73° to 89° was observed for nozzles N1, N2 and N3as pressure increased from1to 4 kg/cm2respectively.
