Weeds are unwanted and undesirable plants that grow naturally alongside cultivated crops in agricultural fields. Two common examples of weeds are Xanthium (Gokhroo) and Parthenium (Gajar ghas). \nIt is essential to remove weeds from crop fields because they compete aggressively with the main crop plants for basic requirements like sunlight, water, nutrients, and space. As a result, the main crops receive insufficient nutrition, leading to stunted growth and reduced crop yield. Removing them early ensures proper nutrient availability and optimal growth for the cultivated crops.
