Abstract: A field experiment was conducted at Main Agricultural Research Station (MARS), College of Agriculture, Dharwad where six herbicides namely Glyphosate, Paraquat, Glufosinate ammonium, Saflufenacil, Halosulfuron and Imazethapyr were tried as a post emergence in addition to pre-emergence application of Atrazine. Totally nine treatments were tested using Randomized Block Design having three replications with two control (Weedy check and weed free check) and one standard RPP check. At all the growth stages weed free check was recorded higher weed control efficiency (WCE) than rest of the weed control methods. However after application of post emergence herbicides Atrazine @ 1 kg ha-1 fb Glyphosate @ 2.5 kg ha-1 was recorded with WCE of 92.12 percent next to weed free check. Weed free check was recorded significantly higher grain yield (84.59 q ha-1), stover yield (114.10 q ha-1) and harvest efficiency (42.57 %) which was followed by Atrazine @ 1 kg ha-1 fb Saflufenacil @ 75 g ha-1. Weed free check was recorded significantly higher gross return (₹ 98206 ha-1), whereas Atrazine @ 1 kg ha-1 fb Saflufenacil @ 75 g ha-1 was recorded significantly higher net return (₹ 64405 ha-1) and B:C ratio(3.14).
