Allelopathic Potential

Allelopathic effects of Parthenium hysterophorus were studied on seed germination and seedling growth of Triticum aestivum, Oryza sativa, Glycine max and Cajanus cajan. The shade dried leaves of Parthenium hysterophorus were soaked in distilled water for 24 hours at room temperature to obtain aqueous extract and sterilized seeds were treated with 2%, 4%, 6%, 8% and 10% concentration of P. hysterophorus leaves aqueous extract. The germinated seeds were counted every day to observe mean germination time. It has been found that significant time is taken to germinate with increasing concentration. It has been also observed that germination percentage, root length, shoot length and seedling vigour value were reduced at >2% as compared to control. The 10 % aqueous extract showed the maximum inhibitory effect on seedling growth. In the present investigation, the leaves aqueous extract of P. hysterophorus had strong inhibiting effects on seed germination and seedling growth. It is necessary to keep this weed under check at the emerging stage at agro crop field so that crop growth constraint may be avoided

Allelopathy is a phenomenon of direct or indirect, beneficial or adverse effects of a plant on its own or another plant through the release of chemicals into the environment. This experiment was carried out to determine the allelopathic effect of Cyperus rotundus L. (purple nutsedge) tuber aqueous extract on seed germination and initial growth of Glycine max L. (soybean) seedlings. The experiment was performed in completely randomized (CRD) design with five replications, using a range of concentrations of aqueous tuber extracts of nutsedge, i.e.: 0%, 5%, 10%, 15%, 20% and 25%. The petri dish experiment showed that with increase of the tuber extract concentration, a significant increase was noted in mean germination time (MGT), significant decreases in germination index (GI), growth tolerance index (GTI), wet weight seedling, dry weight seedling and  length of soybean seedling.
