Abstract	Allelopathy refers to the direct or indirect chemical effect of one plant on another through the release of secondary metabolites known as allelochemicals into the environment. In agriculture, this natural ecological phenomenon has gained significant attention as a sustainable alternative to synthetic herbicides, pesticides, and fertilizers. Allelochemicals such as phenolic acids, terpenoids, alkaloids, and flavonoids are released through root exudation, volatilization, leaching, and residue decomposition, influencing weed germination, pest activity, and soil microbial dynamics. The integration of allelopathic crops like rice, wheat, sorghum, sunflower, and rye into farming systems can suppress weeds, reduce pathogen incidence, and improve nutrient cycling without degrading soil health or contributing to chemical residues. This aligns with the core objectives of sustainable development in agriculture: enhancing productivity, conserving biodiversity, minimizing environmental pollution, and reducing input costs for farmers.
Keywords	Allelopathy, Allelochemicals, Volatilization, Sustainable development, Flavonoids.
