Abstract:

The chemical compounds have been reported to be exuded by plants and their inhibitory effects of other plants. The research work was carried out to study the allelopathic effect of root, bark and leaf extracts of Azadirachta indica L. on the seed germination of Abelmoschus esculentus L. Germination studies were conducted in laboratory, the bhendi seeds treated with the root, bark and leaf extracts of Neem. On the seventh day the morphological parameters, photosynthetic pigment and biochemical contents were analysed. The result showed that the rate of germination of bhendi decreased in all Azadirachta indica L. extracts. The reduction in biochemical contents of bhendi was also noted. The highest rate of germination was observed in control (distilled water) treatment and the highest rate of inhibition was observed in root extract followed by bark and leaf extracts.
