Response of different doses of aqueous extracts of Poplar leaf was studied on germinating seeds and early seedling growth. Five doses comprised of distilled water (control), 0.5, 1.0, 1.5 and 2.0 ml application of leaf leachates were treated. The effect of aqueous extracts was found inhibitive indicating a direct proportional relationship with increased application of leaf leachates for all the parameters studied. Each variety showed maximum extent of phytotoxicity at 2 ml leachates application in comparison to untreated control. The range of susceptibility to applied allelochemical among Wheat varieties was found in the order of ‘H.D. 2285’ > ‘Sonalika’ > ‘H.D. 2380’ > H.S. 295’, while in case of Maize varieties, lower phytotoxicity (resistance) was observed in ‘PSCL-3438’ and ‘Naveen’ in comparison to that in ‘Parvati’ and ‘Sartaj’ (susceptible to phytotoxicity).
