Abstract:
Cymbopogon (Jones) Schult reduced the growth of Brassica campestris, Pennisetum, Setaria italica and Dichanthium annulatum in root mixed culture in pot and field experiments. Aqueous extracts from leaves, stems and roots; root exudates, litter mulch and soil collected from beneath Cymbopogon significantly arrested the germination and early growth of afore-said test species. All the species except Dichanthium annulatum exhibited low moisture contents in nutrient rich growth medium containing shoot extract or mulch. Chromatographic studies of shoot extracts revealed the presence of caffeic, p-coumaric, ferulic, chlorogenic and p-hydroxybenzoic acids. The toxicity depend upon the part assayed and test species used. Germination and growth were independently affected.
