Online published on 11 January, 2012. Abstract In the present study the leachates leaf, bark and fruit pulp of Phyllanthus emblica were used for observing their allelopathic effects on germination and growth of Eleusine coracana, Phaseolus mungo, Setaria italica and Amaranthus caudatus. The higher concentration (10.0%) of leaf leachate showed maximum (100.0%) reduction in germination and growth of A. caudatus. Lower concentration (2%) of bark leachates inhibited maximum (47.00%) germination of S. italica. Bark leachate (2%) stimulated 15.55 & 37.04% radicle and plumule growth of S. italica and A. caudatus, respectively. Fruit pulp of P. emblica was more toxic for A. caudatus and drastically inhibited the germination and growth. Leaf leachate of P. emblica were more toxic for germination and growth of all the test crops.
