Field experiment was conducted during kharif (June-July), 2009_10 to study the management of monocot weeds in irrigated groundnut. The experiment was laid out in randomized block design with 8 treatments with 3 replication. TG-24 variety of groundnut was used in the trial. Results of the experiment revealed that application of imazethapyr and chlorimuron (100+24 g ha−1) recorded maximum nodules plant−1, plant height, pods plant−1, pod yield, kernel yield, haulm yields followed by imazethapyr 300 g ha−1 and imazethapyr 200 g ha−1. Based on the data the highest pod yield 13.37 q ha−1 was recorded with hand weeding at 20 and 40 DAS which was statistically at par with imazethapyr + chlorimuron (100+ 24 g ha−1) 12.70 q ha−1, combination of imazethapyr + chlorimuron fetched the highest net monetary return of Rs. 14312 ha−1 and B:C ratio of (1.8), which might be due to less cost of labour in this treatment.
