Plants have several direct or indirect effects on other surrounding organisms in which it may be harmful or beneficial, in this study the potential allopathic effects of Ziziphus spina-christi (Sidr) leaf extracts were investigated alongside wheat (Triticum aestivum L), barley (Hordeum vulgare L.), cress (Lepidium sativum L.) and fenugreek (Trigonella foenum-graecum L.) Seeds for the observation of their germination, in which different concentrations (0%, 2.5%, 5.0%, 7.5%, and 10%) of sidr aqueous and methanolic extracts (70% methanol) were made and used against these seeds in vitro and their effect on germination was determined. This experiment showed a significant inhibitory effect of both extracts on seed germination at all concentrations and it became more effective as the concentration rises, as a result, sidr leaf extracts may demonstrate the use of this species as an herbicide and provide significant agricultural success
