Trial Name: 2022 Allelopathic Effects of Cover Crops on a Crop Rotation
Description
Allelopathy is the direct or indirect impact on plant individuals, whether they belong or not to the same species. Established as substances composed of secondary metabolites, allelopathy can a) affect growth and yield of another plant and b) develop autotoxicity, where plant individuals’ secrete chemicals that prevent propagation and development of seedlings of same species growth.
Allelopathy can be used as a strategic tool to mitigate chemical weed management. Residues of allelopathic cover crops not only provide benefits to the soil but also help to reduce weed populations during their growth and likely for the cash crops seeded in the season thereafter.
