Abstract

In present study the allelopathic effect of aqueous leaf extracts of Clerodendrum viscosum, Ageratum conyzoides and Parthenium hysterophorus was observed on the seed germination of Chickpea in vitro (Cicer arietinum.L.).Seed germination was found to be inhibited in all the leaf extract concentrations used i.e. 2%,4%,6%,8% and 10%. However higher inhibition was observed in the 10% leaf extract of the test plants (i.e. Cl. viscosum, Ag. conyzoides and P. hysterophorus). In compare to all allelopathic plants extracts more inhibition was found in P. hysterophorus leaf extract followed by Cl. viscosum and Ag. conyzoides. Higher inhibition of radical and plumule growth of the Chickpea seeds was found with the increase in concentration of the leaf extracts used. Percentage of germination of Chickpea seeds was found to be low in 10% concentration whereas in untreated seeds it was found to be more.
