Abstract
Most of the developing countries apply pesticides using a lever operated knapsack (LOK) sprayer. In this method, operator swings the lance in front of his movement. Therefore, it is impossible to maintain a constant nozzle height that produced an uneven spraying. In addition, operator contaminated himself. To overcome this problem, a project was undertaken to design and develop a boom for LOK (Lever Operated Sprayer) sprayer. The development and experiment were done in Department of Farm Power and Machinery workshop at Bangladesh Agricultural University. The boom and frame were fabricated and its performance was tested as the research work. Forward speed of the operator while spraying was recorded as 2.015 km/hr. The effective field capacity of the boom sprayer was found as 0.145 ha/hr. This research observed that field efficiency was 71.86%. The fabrication cost of the boom sprayer was found to be 2310 tk. It was also found that the spraying service charge if estimated 700 Tk/ha, including a profit of 342 Tk/ha, the spraying operation using the machine to cover more than 2.53 ha per year will be profitable.
Key Words: Boom design, Economic use, Fabrication cost, Modified knapsack sprayer, Optimum spraying height.
