A Review on Weed Characteristic and Weed Management for Sustainable Farming

A major obstacle to agricultural productivity worldwide, weeds pose serious problems for crop yield and quality. They are fierce rivals to farmed crops because of their competitive nature, quick growth, and capacity for environmental adaptation. With an emphasis on how weeds affect nutrient availability, water resources, and light competition, this paper offers a thorough examination of how weeds affect crop productivity. The paper also examines contemporary weed management techniques, such as mechanical, chemical, cultural, and biological control approaches. Along with integrated weed management (IWM) strategies that seek to strike a compromise between effectiveness and environmental and economic sustainability, the development of herbicide resistance and the growing concern about its effects on sustainable agriculture are also covered. Finally, the potential of new management techniques and emerging technology, like genetic modification and precision agriculture, to enhance weed control and reduce adverse crop effects is assessed. In order to lessen the negative effects of weeds on global food security, the review's conclusion emphasizes the significance of implementing a variety of flexible weed management techniques.
