A field experiment was conducted at Pusa (Bihar) during wet season of 2005 and 2006 to evaluate the efficiency of weed management practices under different nitrogen scheduling on weed growth and yield of wet direct seeded rice Twenty five treatment combinations consisted of five weed management practices and five nitrogen scheduling practices. The various weed management treatments significantly decreased the density and dry weight of weed and increased the weed control efficiency, grain and straw yield compared with the unweeded check. Butachlor with Safener combined with one hand weeding, was at par with two hand weeding, recorded maximum values of the entire yield attributes and yield with lesser weed density and dry weight over weedy check. Application of N in 4-5 splits produced maximum grain yield and net return of wet seeded rice.
