Allelopathic potential of Diospyros kaki L. against Triticum aestivum L., Brassica compestris L. and Trifolium alexandrinum L

Allelopathic studies of Diospyros kaki L. were conducted by using aqueous extracts from leaves, bark, litter and mulching in various experiments. It was observed that the germination, radical growth, plumule growth, no. and growth of seminal roots, fresh weight and dry weight of Triticum aestivum L and Brassica campestris L. and Trifolium alexandrinum L. were significantly reduced in various bioassays. The aqueous extracts of leaves were inhibitorier than the bark extracts for the test species Triticum aestivum L. Aqueous extracts obtained at room temperature were inhibitorier than hot water extracts. Litter and mulching experiments also showed inhibitory effects. Further studies are required to see its allelopathic behavior under field condition against its associated species, to identify the toxic principle, and to evalvate as biocontrol agents for weeds, insect and disease control.
