摘  要:This investigation was carried out at Faculty of Agriculture and Forestry-University of Duhok/Kurdistan-Iraq. Three experiments were included in this investigation: (1) First experiment was a bioassay related to the germination performance, shoot and root development of corn (Zea mays L.) and peanut (Arachishypogaea) at two concentrations of root (3% and 1.5%) and shoot (12% and 6%) aqueous extracts of corn medium; (2) The second experiment dedicated to the intercropping of corn and peanut at four treatments; (3) While the third experiment involved the effect of peanut root exudation on growth of corn. Experiment results revealed that corn shoot and root water extracts highly inhibited seed germination of both corn and peanut, the inhibitory of shoot extract was more than root aqueous extract. While its effect on the seedling growth was vice versa as compared with control treatment, there was an increase in root and shoot length of both corn and peanut when grown in corn aqueous extracts. Intercropping experiment results has stimulated most traits of peanut under studying. Also for corn, there was apparent and significant increase in all characteristics as compared with control. It was further confirmed from the results of peanut root exudates that had all studied characters of corn were stimulated than the control treatment.
