A field experiment was conducted on sandy loam soil to study the “Effect of weed management on weed dynamics, yield and quality of groundnut (Arachis hypogaea L.) under northern hill of Chhattisgarh’’at Research-cum-instructional farm of Raj Mohini Devi College of Agriculture and Research Station, Ajirma, Ambikapur, Chhattisgarh, during kharif season of 2023. The experiment comprising of 9 treatments with three replications laid out in randomized block design. The results revealed that hand weeding at 20 and 40 DAS recorded significantly maximum weed control efficiency (%), lowest weed density (m^-2) ,lowest dry weight of weed (g m^-2) and lowest weed index (%), higher pod yield (1930 kg ha^-1), haulm yield (2610 kg ha^-1), harvest index (42.51%), seed index (44.74%), shelling percentage, quality parameter such as oil content (48.30%) with maximum net return (₹ 77466 ha^-1) and BCR (2.02). However, integrated weed management practices application of Pendimethalin @ 0.75 kg ha^-1 PE fb Imazethapyr @ 75 g ha^-1 at 20 DAS followed by Pendimethalin @ 0.75 k ha^-1 PE fb Quizalofop-ethyl @ 40 g/ha at 20 DAS also recorded higher weed control efficiency, yield attributes, pod yield and haulm yield compared to other treatments.
