Abstract

A floristic survey of rice agro-ecosystems of Yamoussoukro, Attiegouakro and Didievi in Cote d’Ivoire. The floristic and phytosociological surveys contribute to an in-depth analysis of major weeds affecting rice growing in agro-ecosystems. These surveys sort out the qualitative and quantitative aspects of flora weeds. As a result, 227 species distributed in 151 genera and 56 families were recorded. The most represented families are Poaceae, Cyperaceae, Asteraceae, Euphorbiaceae, Rubiaceae and Fabaceae. The species inventory helps to reveal 5 major weeds. Regarding the centesimal frequency and abundance-dominance, there are Cyperus difformis L. and Echinochloa crus-galli (L.) P.Beauv. Fimbristylis littoralis Gaudich., Sphenoclea zeylanica Gaertner and Leptochloa caerulescens Steud..
