Management of weeds in irrigated groundnut (Arachis hypogaea L.) under satpura plateau and hill zone

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.
