Traditional yam cropping systems are based on shifting cultivation
and slash and burn which lead to deforestation and soil degradation. The objective of this study was to determine the productivity of cropping sequences with herbaceous legumes and
their effects on the profitability of subsequent yam. We compared
smallholders’ traditional cropping sequences (one-year fallow of
Andropogonon gayanus, maize) with those using herbaceous
legumes (maize-Aeschynomene histrix, maize-Mucuna pruriens
var utilis) during 2002–2005. Highest dry mater, nutrients recycled, and net nitrogen contribution were found with Mucuna
preceding yam (P < 0.001). Highest net revenue and return on investment were achieved in yam-based with legumes.Raphiou Maliki National Agricultural Researches Institute of Benin (INRAB),
