Allelopathy in Crop Production – A Review
Authors
Abstract
One of the most significant biological barriers to agricultural production systems is weeds. They
compete with crops for nutrients, sunshine, space, and water, which has a negative impact on crop development
and output. Allelopathy is the ability of plants to either promote or inhibit the growth of other plants in their
surroundings by the release of compounds into the surroundings. The compounds that are so released are
primarily secondary metabolites, known as allelochemicals. Allelopathy based weed management has the
potential to increase productivity without harming the environment, which proves essential for scientists trying
to ensure that there will be food for future generations. The main objective of this review article is to focus the
effect of different allelopathic measures in weeds, pests and diseases management. These include the use of
allelopathic cultivars, intercropping with plants that suppress weeds, using residues, mulches, cover crops and
crop water extracts that are allelopathic.
