Weeding consists of uprooting and removal of unwanted plants which grow in a filed with a cultivated crop competing with the crops for moisture and plants nutrients. Suitable mechanization technology is needed to reduce drudgery and to enhance time lines of operation. Hence a study was conducted to evaluate the performance of power weeder, wheel hoe and star weeder under dry land condition. Three weeders were initially evaluated in the dry land planted with maize with a plot size 20 m × 10 m with row to row spacing of 60 cm. Actual field capacities of power weeder, wheel hoe and star weeder were 0.0494 ha/h, 0.022 ha/h, 0.021 ha/h respectively. Field efficiencies of power weeder, wheel hoe and star weeder are 82.33%, 73.66%, 80.76% respectively. Power weeder has more field efficiency than other two weeders. Weeding efficiencies of power weeder, wheel hoe and star weeder are 78.4%, 74.0%, and 75.4% respectively. Power weeder has more weeding efficiency than other two weeders. Operational cost is more for power weeder and less for wheel hoe, star weeder compared to power weeder. Wheel hoe is having less efficiency and less cost of operation among the three weeders. Since drudgery involved during weeding is more compared to other weeders hence, it could be given less preference to weed when compared between power weeder and star weeder.
