Weed management in irrigated sesame (Sesamum indicum L.)

A field experiment was conducted in Kolaram village, P. Velur Taluk, Namakkal district to evolve a suitable weed management programme for irrigated sesame variety CO 1 during summer season (March - June) 2018. The experiment was laid out in Randomized Block Design (RBD), replicated thrice with ten treatments viz., unweeded control, hand weeding twice (15 and 30 days after sowing (DAS)), pre emergence application of alachlor 1.5 kg ha-1, fluometuron 0.9 kg ha-1, post emergence application of propaquizafop 0.05 kg ha-1, quizalofop ethyl 0.05 kg ha-1 and combinations of pre and post emergence herbicides application. From the results, it is concluded that pre emergence application of alachlor 1.5 kg ha-1 on 3 DAS + post emergence application of quizalofop ethyl 0.05 kg ha-1 on 21 DAS was an efficient and economically feasible package to manage the weeds and to realize better returns from irrigated sesame.
