Abstract
An investigation was conducted at Chatha Farm of Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu during kharif seasons of 2006 and 2007 on the efficacy of different herbicides on growth and yield of direct wet seeded rice (DWSR) sown through drum seeder. Fourteen weed control treatments were tested in randomized block design replicated thrice. All the weed control treatments significantly reduced the population and dry weight of weeds which resulted in significantly higher growth and yield of rice over weedy check. Though the weed free treatment yielded significantly higher than other treatments, but it was not economical (1.55 B: C ratio). Among the herbicides pretilachlor @ 0.5 kg/ha at 6 DAS fb rotary hoe at 20 DAS not only significantly reduced population and dry weight of weeds but also increased the grain yield of rice with the concomitant increase in the yield attributes and also resulted in highest net returns (Rs. 25918/ha) and benefit: cost ratio (2.25).
