Abstract

Nowadays, agricultural sprayers are the most widely used equipment to carry out pesticide applications. Several kinds of sprayers have been developed from hand-operated, hydraulic sprayers to boom/speed sprayers or aircraft sprayers with the development of agricultural engineering. The objectives of this study were to design a self-propelled field sprayer to be operated and controlled remotely and evaluate the performance of the purposed machine at different forward speeds of 9.33, 8.39, 7.46, 6.48, and 6.22 km/hr and different pump pressure of 9.5, 8.5, 8, 7 and 6 bar under laboratory conditions. Also, evaluate and calibrate the performance of the spraying system. The results showed that the maximum actual field capacity was 8.66 fedd/hr at 9.33 km/hr, and the total operation cost was 60.44 EGP/hr (6.98 EGP/fedd) at 9.5 bar.
