The present study was conducted to assess the allelopathic effects of leaf and bark aqueous extracts of Populus ciliata, Pyrus pashia and Prunus cerasoides on Glycine max, Eleusine coracana, Echinochloa frumentacea and Amaranthus hypochondriacus under laboratory and field conditions. Tested tree species exhibited inhibitory effects on studied crops. Inhibitory effect was more pronounced in laboratory than that recorded in field conditions. Under laboratory conditions, P. ciliata showed maximum allelopathic effect; while, under field conditions, negative effect was not observed in studied crops. Among test crops, maximum germination (%) was recorded in G. max and minimum in E. coracana. Leaf extracts of P. ciliata and P. cerasoides showed stimulatory effect on A. hypochondriacus and E. coracana, and bark extracts of P. pashia and P. cerasoides showed stimulatory effects on G. max.
