Allelopathic Effect of Leaf Extract of Parthenium hysterophorus L. on Seed Germination and Growth of Cicer aeritinum L.

We studied the allelopathic effect of Parthenium hysterophorus on seed germination, root & shoot length and fresh weight of root & shoot and fresh weight of root & shoot, and seed vigour index (SVI) were calculated also. In this study allelopathic effect of leaf extract of different concentrations (5 %, 10 %, 15 %, 25 %, 50 %) were compared with control treatment. Seed germination and growth performance of Chickpea were low at high concentrations of leaf extract except for shoot length and fresh weight of shoot.
