Abstract

Enhancement of rice yield with more profit is major concern among scientists and round the clock efforts are being made to alleviate this situation. Competition between crop and weed is just struggle for nutrients, space, light and water resulted in poor yield. This competition not only affects yield but also increase cost of cultivation resulting in low profit over investment. Weed is considered one of the yield reducing factor. An experiment was conducted to evaluate a potent low dose herbicidal combination for broad spectrum weed management in transplanted rice during kharif 2015 at Jawaharlal Nehru Krishi Vishwa Vidyalaya, (JNKVV), Jabalpur (M.P.) using randomized block design (RBD) with seven treatments and four replications. Critical parameters -Weed population (No. m-2), Weed dry weight (g m-2), Weed control efficiency (WCE, %) and weed index (WI, %) were observed to see the efficacy of applied chemicals. Mixed application of weedicides Bensulfuron methyl 60 g with pretilachlo
