Abstract:
The effect of leaf and root extract of Cyperus tuberosus on the seedling growth of groundnut (Arachis hypogaea) was investigated using six aqueous extracts levels (0, 0.5, 1.5, 2.0 & 3.0 g/cm 3). It was observed that the toxic chemical released by C. tuberosus aqueous extract has more effects on groundnuts as significant depression on shoot and root growth was observed. Also shoot growth was more affected than root growth. The results revealed that different concentrations of leaf extracts caused significant inhibitory effect on root and shoot elongation of the receptor crops. Bioassays also indicate that the inhibitory effect was proportional to the concentrations of the extracts and higher concentrations had the stronger inhibitory effect, whereas, the lower concentrations showed stimulatory effect in some cases. This investigation also shows that the leaf extract of C. tuberosus have more allelopathy than seed extract.
