Abstract
The weed should be controlled and eliminated at their early stage. Depending upon the weed density, 20 to 30 percent loss in grain yield is quite usual which might increase up to 80 percent if adequate crop management practice is not observed. The present study was conducted in Prayagraj district of Uttar Pradesh, The manual weeder was fabricated by using locally available material. The developed weeder is capable of reducing time wastage, labor requirement and power consumption. The performance evaluated in terms of weeding efficiency and capacity of weeder. The minimum losses, maximum efficiency and highest quality are achieved by the developed weeder. The average efficiency of weeder was observed for single point type shovel and duck type shovel as 88.51% and 85.043% respectively. The average capacity of weeder was observed for single point type shovel and duck type shovel as 0.0512 ha/day and 0.0492 ha/day respectively
