Abstract
The present investigation was carried at Research Farm of R.A.K. College of Agriculture, Sehore (Madhya Pradesh), during Kharif season (2016). Six weed control practices were evaluated in randomized block design with three replications. The results of present study revealed that hand weeding twice at 30 and 45 DAS recorded higher growth and yield attributes followed by application of imazethapyr 35% + imazemox 35% 70 WG 70 g/ha at 20 DAS (PoE) and pendimethalin 30 EC 1 kg/ha (PE) fb imazethapyr 10 SL 100 g/ha (PoE). Application imazethapyr 35%+imazamox35% 70 WG 70 g/ha (PoE) at 20 DAS recorded highest net return of ₹73870/ha and cost benefit ratio 1:3.58.
