Chromolaena odorata, an invasive plant of the Asteraceae family, is widespread in Africa, particularly in Côte d’Ivoire, where it poses significant challenges to agricultural systems by competing with crops for essential resources. However, this plant also offers ecological and agronomic benefits when integrated into sustainable agricultural practices. It can enrich soils with essential nutrients, such as calcium, and promote soil alkalinization. Additionally, its dense biomass helps control weeds and prevent soil erosion. These underutilized characteristics warrant further investigation into its integration within sustainable agriculture. To this end, an agronomic trial was conducted in Daloa to assess the impact of C. odorata biomass on maize cultivation. Four treatments were tested in a Fisher block design: (i) C. odorata alone (Co), (ii) C. odorata with standard mineral fertilizer (CoNPK), (iii) standard mineral fertilizer alone (NPK), and (iv) a control with no treatment (T0). The results showed that the C. odorata alone treatment yielded the highest grain outputs, closely followed by the use of standard mineral fertilizer. In contrast, the control treatment produced the lowest yields, and the combination of C. odorata and mineral fertilizers resulted in yields lower than those from C. odorata alone. It is recommended to integrate C. odorata as a biofertilizer in sustainable agricultural systems due to its economic and ecological benefits. Further studies are required to define an optimal technical pathway for its use, assess its long-term effects on soils, and determine its potential to enhance crop profitability.

Abstract: (french)
Chromolaena odorata, une plante invasive de la famille des Asteraceae, est largement présente en Afrique, notamment en Côte d’Ivoire, où elle pose des problèmes dans les systèmes agricoles en concurrençant les cultures pour les ressources essentielles. Cependant, cette plante offre aussi des avantages écologiques et agronomiques lorsqu’elle est intégrée dans des pratiques agricoles durables. Elle peut enrichir les sols en éléments nutritifs, tels que le calcium, et favoriser l’alcalinisation des sols. De plus, sa biomasse dense aide à contrôler les mauvaises herbes et à prévenir l’érosion des sols. Ces caractéristiques sous-exploitées justifient une exploration plus approfondie de son intégration dans l’agriculture durable. Dans cette optique, un essai agronomique a été mené à Daloa pour évaluer l’impact de la biomasse de C. odorata sur la culture de maïs. Quatre traitements ont été testés en block de Fisher: (i) C. odorata seul (Co), (ii) C. odorata avec engrais minéral standard (CoNPK), (iii) engrais minéral seul (NPK), et (iv) témoin sans traitement (T0). Les résultats ont montré que le traitement C. odorata seul a donné les meilleurs rendements en grain, suivis de près par l’utilisation d’engrais minéraux standard. En revanche, le traitement témoin a produit les rendements les plus faibles, et la combinaison de C. odorata et d’engrais minéraux a donné des rendements inférieurs à ceux de C. odorata seul. Il est recommandé d’intégrer C. odorata comme biofertilisant dans les systèmes agricoles durables, en raison de ses avantages économiques et écologiques. Des études supplémentaires sont nécessaires pour définir un itinéraire technique optimal pour son utilisation, évaluer ses effets à long terme sur les sols, et déterminer son potentiel pour améliorer la rentabilité des cultures.
