Abstract: In order to proffer an effective management of weeds in agroecosystems, a study which revolves around recognizing the crop-weed inter-relationship is needed. In the light of the above, the interaction of Abelmoschus esculentus (L.) Moench and Tithonia diversifolia (Hemsl) A. Gray) in an agroecosystem located in the University of Ibadan was studied. Abelmoschus esculentus and Tithonia diversifolia were planted in plastic pots in a randomized block design and watered at alternative days with 2 L of water per pot. Results showed that Abelmoschus esculentus planted alone had the greatest plant height, stem diameter, leaf area, number of leaves and biomass accumulation than Tithonia diversifolia grown alone. However, analysis of variance carried out with each of the plants revealed that Tithonia diversifolia had a significant effect (p<0.05) on the dry weight of shoot and root of Abelmoschus esculentus and also on its number of leaves. Abelmoschus esculentus had no significant effect on the leaf area. The inferences of these results were discussed.
