The field experiment was conducted at Post Graduate Research Institute in Animal sciences Kattupakkam Tamil Nadu, India during Rabi (Oct-Mar) seasons of 2016-17 to study the effect of different weed management techniques in direct seeded puddled rice variety ADT 43. The experiment was laid out with unpaired t test design. The treatment of chemical weed management technique (pre - emergence application of pretilachlor) was compared with two time manual weed management technique (control) in direct seeded puddled rice. Among the weed management techniques, chemical weed management technique significantly influenced the growth and yield characters and yield of direct seeded puddled rice. The maximum plant height, number of tillers /hill, grain yield, straw yield and cost benefit ratio were recorded under chemical weed management technique during Rabi. The lowest grain yield, straw yield were recorded under control treatment.
