Abstract
The allelopathic influence of aqueous extracts of Chrozophora obliqua on the germination and seedling growth of Pennisetum typhoides (Bajra) have been determined. It was eminent that 10 g aqueous extracts of leaves and 48 h treatment present inhibitory effect on germination percentage, radical length and number of seminal roots and the cause was found significantly higher than that recorded in the stem and control treatment. The inhibitory effects were increased proportionally with increasing extract concentration and soaking duration. The only exception was observed in the 5 g concentration of leaves that decreased the plumule length. These findings indicate that P. typhoides sown in fields which had leaf and stem litter of C. obliqua will be adversely affected regarding germination, growth and ultimately resulting in lower yield.
Key words: Allelopathy, aqueous extracts, Chrozophora oblique.
