Groundnut is one of the most important oilseed and food legume crops cultivated worldwide, valued for its edible oil, protein rich kernels, and contribution to soil fertility through biological nitrogen fixation. However, weed infestation remains a major constraint in groundnut production, particularly during the early growth stages when the crop exhibits slow initial growth and poor canopy coverage. Uncontrolled weeds compete with crop for nutrients, moisture, light, and space, resulting in significant yield reduction and deterioration in pod quality. Effective weed management is therefore essential to achieve higher productivity and profitability in groundnut cultivation. This review summarizes the major weed flora associated with groundnut fields and discusses different weed management approaches. Mechanical methods like hand weeding remain effective but are often constrained by labour scarcity and increased production costs. Herbicide-based weed management, involving pre-emergence, and post-emergence herbicides, has gained importance due to its efficiency and timeliness. The review also highlights the role of integrated weed management (IWM), which combines multiple approaches for sustainable and eco-friendly weed control while minimizing herbicide resistance and environmental hazards.
