Abstract
Effect of different manually operated weeders on weeds and grain yield of maize was studied. Among the manually operated weeders evaluated, wheel hoe registered an yield increase of 154% over control, took lowest weeding time (71.43 hr/ha), covered maximum area with minimum cost of operation (Rs. 714/ha) on weeding twice on 25 and 45 DAS which was on par with pre-emergence application of atrazine 0.5 kg/ha on 3 DAS followed by hand weeding on 45 DAS.
