Abstract

The allelopathic potential of extracts and residue of sweet potato (Ipomoea batatas L.) Lam. plant clone 'CEMSA 78-354' on weeds seeds germination was examined. Plant residues inhibited the weed emergence and weed seeds germination. The negative Response Index indicated that monocot weeds were less sensitive than dicot weeds.  I. batatas plant parts extracts inhibited seed germination and stimulate radicle length of P. olerasea and A. spinosus. Many phytochemicals (fatty acids, triterpenes, steroids, alkaloids, quinones, phenols, tannins, flavonoids, saponins etc.) with allelochemical potential were detected in I. batatas plant
