Abstract
Allelopathic effect of aqueous extract of Parthenium hysterophorus (L). were studied on seed germination and seedling emergence of some cultivated crops like Triticum aesticum (L)., Zea mays (L)., Sorghum vulgare PERS., Gossipium hirsutum (L). and Glycine max (L).. Seed germination of Zea mays (L). was completely inhibited at
2% leaf extract of Parthenium hysterophorus (L). and in Triticum aestivum (L) it was gradually reduced the seed germination up to the concentration of 10 %. While in Sorghum vulgare PERS. it was inhibited at 6 %. At 4 % aqueous extract the maximum inhibition occurred in Glycine max (L). and Gossypium hirsutum (L). The aqueous
extract of Parthenium hyterophous L. were having strong inhibitory effect on the growth of root and shoot development in the cultivated crops except Triticum aesticum (L). While on Sorghum vulgare PERS., it has shown moderate inhibitory potential
