Allelopathic effect of Parthenium hysterophorus Linn. on crop plants
Aqueous extract of Parthenium hysterophorus L. root and aerial part were tested on six crops for their allelopathic effect on seed germination, growth seedling and seed borne infection at various concentrations in laboratory condition. Aerial part and root extract of Parthenium hysterophorus showed inhibitory as well as stimulatory effect against particular crop plants. Germination of groundnut (Arachis hypogaea L.) was highly affected followed by mung bean (Vigna radiata L.). Where as seed germination in chickpea (Cicer arietinum L.) and soya bean (Glycine max L.) was increased. In aerial part extract, growth of radicle and plumule of A. hypogaea and V. radiata were decreased with increasing concentration of extract as compared to that of control. While the length of radicle and plumule of T. aestivum and P. typhoides were increased. Root extract of Parthenium also revealed inhibitory as well as stimulatory effect. Though the extract of Parthenium exhibited allelopathic effect but reduced seed borne infection in almost all crop seeds. Among all selected crop, A. hypogaea was found to be most susceptible to P. hysterophorus
