Celosia argentia L. is dominant alien weed reported from crop field of Islampur in Walwa taluka of Sangli district of Maharashtra, India. It has been scrutinized for its allelopathic potentiality of C. argentea against fresh weight and dry biomass of seedlings of wheat (Triticum aestivum L.). The laboratory experiments were conducted to assess fresh weight and dry biomass of seedlings of wheat after treating seeds with different concentrations (5, 20, 40, 60 and 80%) of aqueous leachates of inflorescence (flower), leaves and root of C. argentea separately. It was observed that the inflorescence and root leachates treatment responds in decline of dry weight of wheat seedling. The leaf leachates treatment was responsible for enhancement in dry weight of wheat seedlings but at lower treatments (5 to 40%). The higher treatment (60 and 80%) of leaf leachates cause much detrimental effect on dry weight, it reduces dry weight more than half as compared to control. The fresh and dry weight of wheat seedlings was increased after treatment of 5 to 40% leaf leachates however decreased more in 60 and 80% leaf leachates treatments. The allelotoxicity regarding wheat seedling was in pattern of leaf > inflorescence > root leachates were toxic on fresh and dry weight but at higher concentrations (80%). The present study indicated that the allelochemicals are present in the weed, C. argentea. This study needs further screening of allelochemicals and their characterization for detailed study.
