Abstract

A hand operated rotary sprayer was fabricated by using locally available materials such as G.I. sheet, wood, rope and plastic tube. Performance studies were carried out at different throughputs and spraying heights at normal walking speed. The field capacity of the sprayer was 0.49 ha/hr or 16.6 l/ha at spraying height of 50 cm, nozzle speed of 2000 rpm, working speed of 2 km/hr, and spray discharge was 133.5 ml/min. The lateral distributions of the spray liquid from the rotary sparyer were measured. It was observed that about 65% of the total spray output was deposited within the radius of 50 cm of the rotary nozzle. The spray deposition in different heights on paddy plants was measured. The maximum deposition was found at the top of the plant. During spraying operation pulse and respiration rate of operator were recorded. The spraying cost was about US$ 3.5/acre.
