A field experiment was carried out at Agricultural Research Station, Kovilpatti, Tamil Nadu Agricultural University during Purattasipattam (October 2017 to January 2018) to study the effect of different weed management practices in rainfed sesame. The experiment was laidout in randomized block design with three replications having ten different weed management treatments in rainfed sesame variety SVPR 1 under vertisol. Application of Alachlor @ 1.5 kg a.i. ha-1 as pre emergence fb Quizalofop ethyl @ 50 g a.i. ha-1 on 25 DAS as early post emergence recorded significantly lesser weed index and higher weed control efficiency and inturn significantly produced higher plant height, dry matter production, seed yield (550 kg ha-1) and stalk yield (2432 kg ha-1). It was followed by the application of Pendimethalin @ 1.0 kg a.i. ha-1 as pre emergence fb Quizalofop ethyl @ 50 g a.i. ha-1 on 25 DAS as early post emergence.
