Title: Research Article Allelopathic Effect of Some Common Weed Extracts on Seed Germination and Seedling Growth of zea mays l. (maize) var. Local.
Abstract: The present study was conducted to investigate the allelopathic effects of some common 10 weed (Alternanthera sessilis (L.) R.Br,ex DC, Amaranthus tricolor L., Cardiospermum helicacabum L., Corchorus olitorius L., Cyperus rotundus L., Euphorbia heterophylla L., Euphorbia hirta L., Phyllanthus amerus Schumach. & Thonn. , Portulaca oleracea L., Vicoa indica (L.) DC.) extracts (aqueous & ethanolic) on seed germination and seedling growth of maize (Zea mays L.) Var. Local under laboratory conditions. The seeds soaked in aqueous leaf extract of Phyllanthus amerus Schumach. & Thonn showed much reduced incidence of seed mycoflora and more seed germination, seedling emergence, root length and shoot length of maize. It is followed by Portulaca oleracea L., Euphorbia hirta L. Some extract showed completely incidence of seed mycoflora on maize seeds. The root, stem and leaf extract of Cardiospermum helicacabum L. showed stimulatory for seed mycoflora and inhibitory for seed germination, seedling emergence, root and shoot length as compared to other plant extracts and control. The result is demonstrated the allelopathic potential of ten common weeds in same maize field and suggested that those weeds may affect maize seed germination and seedling growth due to inhibitory or stimulatory effect of allelochemicals which are present in the extract of weeds.
