Resumo: 	ABSTRACT: The present research work was undertaken to find out the phytotoxic effects of different concentrations of aqueous extracts of leaves, stems and root of milkweed (Calotropis procera) in the Agronomic Research Area of Department of Agronomy, Faculty of Agriculture, Gomal University, Dera Ismail Khan, Khyber Pakhtunkhwa (KPK), Pakistan during 2013-14 and 2014-15. The treatments consisted of different concentrations of aqueous leaf, stem and root extracts (10, 20, 30 and 40%) of milkweed, which were compared with tap water (control). The results showed that the reduction of all studied parameters, including weeds, growth and yield of wheat was proportional to the concentration of aqueous extracts of milkweed in use. The level of inhibition was concentration-dependent as inhibition increased with an increase in the concentration of aqueous extracts of all three plant parts of milkweed. Therefore, application of maximum concentration (40%) of aqueous leaf, stem and root extracts correspondingly reduced all the studied parameters. On the basis of the findings, it is concluded that the Calotropis procera should be removed near the cultivating wheat fields because it contains some phytotoxic substances, which may be leached out by the roots and cause serious losses to the growers and crop species.
