Allelopathic effect of different accessions of Jatropha curcas on field crops in Bundelkhand Region (U.P.) India

Abstract

<jats:p>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 &gt; T. aestivum &gt; Raphanus sativus &gt; Linum usitatissimum. Invariably, maximum inhibition was observed in the higher concentrations of aqueous extract.</jats:p>
