Abstract– Weeds are plants which grow elsewhere and are generally unwanted in the crop fields. In the wheat fields of Kosi region in Bihar, weeds are found growing luxuriantly and affect wheat crop in many ways. The present paper is based on experiment conducted to examine the Allelopathic effect of weed (Phalaris minor Retz.) extract on wheat (Triticum aestivum L.) var. “Vidisha”. Various concentrations of weed (Phalaris minor Retz.) extracts i.e., 5%, 10%, 15%, 20% were prepared in distilled water and used for the treatment of seeds of wheat (Triticum aestivum L.) var. “Vidisha” in triplicate for seven days. The said concentrations were applied to examine per cent seed germination, growth and vigour of the seedlings. It was found that weed extracts reduced the percent seed germination over control (0%), while growth of the seedlings showed increased root and shoot lengths.
