Abstract
The study was conducted to investigate the allelopathic effects of leaf powder of Rumex dentatus L., Euphorbia helioscopia L., Parthenium hysterophorus L. and Carica papaya L. on seed germination and seedling growth of Avena fatua L., R. dentatus, Helianthus annuus L., Triticum aestivum L. and Zea mays L. using a laboratory bioassay. Seed germination, radical and plumule length of T. aestivum were significantly suppressed by R. dentatus and P. hysterophorus leaf powder whereas these parameters were not suppressed by E. helioscopia and C. papaya leaf powder when compared to their control treatments. Euphorbia helioscopia and P. hysterophorus leaf powder application decreased the seed germination and subsequent seedling growth of A. fatua and R. dentatus. There was no effect on growth of Z. mays and H. annuus when the leaf powder of E. helioscopia was applied on their seedlings. Rumex dentatus exhibited auto-toxicity.
