Abstract
The present study aimed at evaluating the effects of aqueous extracts of two dominant weed species on seed germination and seedling growth of tobacco. At the high concentration (6%), leaf aqueous extract of digera muricata mart. Was found to have the inhibitoriest effect, whereas inflorescence extract of chinopodium murale l. was found very less inhibitory effect of nicotiana tabacum followed by those of the other plant extracts after five days. All aqueous extract of two weed species inhibited seed germination and seedling growth of nicotiana tabacum when compared with distilled water.
