Allelopathic effects of aqueous extract of pagoda tree and creeping jenny on five crop plants including wheat (Triticum aestivum), barley (Hordeum vuIgare), corn (Zea mays), millet (Pennisetum americanum) and chickpea (Cicer arietinum) were investigated in a series of experiments conducted at the faculty of Agriculture, SB University of Kerman, Iran. Experiments were based on RCBD with 3 replications in greenhouse condition and CRD in laboratory condition in which different concentrations of weed leaves extract including (0, 25, 50, 75 and 100% of a stock solution (10%W/V)) were applied on all crop plants at germination and seedling growth stages and different responses were measured. Results showed that the three way interaction effect of alkaloid × concentration × hybrid was significant on the traits in both greenhouse and laboratory. By increasing the concentration of alkaloid, inhibitory effect was also increased. The 100% concentration was most effect and control concentration was least effective. There was a significant difference between the two weeds in terms of allelopathic effects and creeping jenny reduced plants growth more compared to pagoda tree. However, all crops were significantly affected by allelopathic properties. It was concluded that pagoda tree and creeping jenny residues in the field had the potential of allelopathic effects on crop plants therefore should be removed from the field before planting.
