Response of post-emergence herbicides on weed control and yield in Sesame [Sesamum indicum (L.)]

A field experiment was carried out at the Research Farm, Department of Agronomy, College of Agriculture, RVSKVV, Gwalior (M.P.) during kharif 2013-14. Treatment two hand weeding at 20 and 40 DAS recorded significantly higher grain yield (673.61 kg/ha) followed by Propaquizafop 10% EC @ 50 g a.i./ha PoE (515.83 kg/ha). Treatment two hand weeding at 20 and 40 DAS recorded significantly higher weed control efficiency(95.5 %), followed by PoE application of treatment Propaquizafop 10% EC @ 100 g a.i./ha PoE (73.08 %). Treatment two hand weeding at 20 and 40 DAS also gave highest values for economical parameters viz., B:C ratio (2.81) and net income (48703.32/ha) followed by treatment Propaquizafop 10% EC @ 50 g a.i./ha PoE.
