| Summary: | Spraying of pesticides and cutting the grass is an important task in the agricultural sector to protect the crops from insects for obtaining high yield. In this study, a solar-powered sprayer cum grasscutter was introduced. The total fabrication cost of the solar powered sprayer cum grasscutter was 12550 Tk.. The application rate of the sprayer was 281.25 lit/ha with spray coverage of 46.7%. The theoretical field capacity and the effective field capacity of sprayer cum grasscutter were 0.08ha/hr and 0.06ha/hr respectively. The field efficiency of solar-powered sprayer cum grasscutter was found 75%, for an average of 2.1 km/hr operating speed. This research observed that cutting efficiency was 79%. The operating cost of the machine was 903.17 Tk/ha. The solar-powered sprayer cum grasscutter is free from pollution because no fuel is needed. The price of the machine is low as compared to others, which are available in the market. [Fundam Appl Agric 2021; 6(1.000): 35-42]
