Weed management continues to be one of the major challenges faced in organic farming because synthetic herbicides are not permitted. Organic farming systems depend on cultural, mechanical, biological, and ecological methods that strive to achieve a balance between productivity and environmental sustainability. Cultural techniques, such as crop rotation, intercropping, and cover cropping, help suppress weeds by boosting crop competitiveness and enhancing soil fertility. Mechanical strategies, including tillage, mulching, and flame weeding, offer immediate weed control but can often be labor- and energy-intensive. Biological and ecological practices, like allelopathy, livestock integration, and interactions with soil microbes, provide eco-friendly solutions that enhance biodiversity, although their effectiveness can vary. Increasingly, integrated weed management (IWM) systems that integrate these various methods are being investigated to improve control while preserving soil health and crop yields. Recent advancements like robotic weeders, biodegradable mulches, and precision technologies open up new possibilities for sustainable weed management. Nonetheless, significant obstacles persist, including elevated labor expenses, reduced yields due to inadequate weed control, and the effects of climate change on weed behavior. This review compiles existing knowledge and underscores future possibilities, stressing the necessity for extensive field trials, adaptive approaches in response to changing climatic conditions, and enhanced policy backing along with farmer education. Progressing toward sustainable weed management in organic farming will be vital for boosting crop yields, protecting biodiversity, and achieving global food security objectives.
