Abstract: An experiment was conducted during the rainy (kharif) seasons of 2013 and 2014 at Gwalior, Madhya Pradesh, to study effect of post-emergence herbicides on yield and economics of sesame (Sesamum indicum L.). The ex- periment was laid out in a randomzied block design (RBD) replicated thrice, with 8 treatments. Sesame variety TKG 22 was grown by adopting recommended package of practices except weed-control measures which were applied as per treatments. Two hand-weedings at 20 and 40 days after sowing (DAS) gave significantly higher weed control efficiency (94.14%), followed by propaquizafop @ 125 g a.i./ha (69.51%) over rest of the weed-con- trol treatments. Pooled results showed significantly higher growth and yield attributes and seed yield (718 kg/ha), stalk yield (3,243 kg/ha), gross income ( 73.4 103), net income ( 47.3 103) and benefit: cost ratio (2.82) under 2 hand-weeding at 20 and 40 DAS over rest of the weed-control treatments, followed by propaquizafop @ 50 g a.i./ha. Application of propaquizafop @ 125 g a.i./ha produced phytotoxicity on sesame plants and subsequently affected the growth attributes in crop; however, symptoms of chlorosis disappeared 2530 days after application of herbicides.
