Abstract
Manual weeders reduce labour requirements compared with hand weeding but remain time-consuming and physically demanding in paddy cultivation. A rotary power weeder powered by a 4.5 hp single-cylinder, air-cooled engine and equipped with three rotary units was developed for direct-seeded paddy and evaluated under field conditions. The machine was tested at three forward speeds and compared with manual weeding using a khurpi. Weeding efficiency decreased with increasing forward speed, whereas plant damage and power requirement increased. The highest grain yield and benefit–cost ratio were obtained at 1.27 km h⁻¹, which was identified as the optimum operating speed. Field evaluation demonstrated that the developed machine reduced labour requirements, provided effective weed control, and improved the operational efficiency of mechanical weed management in direct-seeded paddy cultivation.
