ABSTRACT
Allelopathic effect of three accessions of Jatropha curcas on four field crops viz. Triticum aestivum, Raphanus sativus,
Linum usitatissimum and Lens esculenta through bioassy was studied in laboratory. The level of inhibition of aqueous leaf
extract of J. curcas varied with its accessions and type of tested field crops. The tolerance of the crops was in order of
Lens esculenta > T. aestivum > Raphanus sativus > Linum usitatissimum. Invariably, maximum inhibition was observed in the
higher concentrations of aqueous extract.
Key words : Allelopathy, Field crops, Jatropha curcas, Leaf aqueous extract.
