Abstract
The principal driving force in agricultural research is to increase the yield of food crops For farming to remain productive it will be necessary to replenish the nutrients removed or lost from the soil The objective of this study was to determine the impact of yambased systems on soil productivity dry matter production nutrients recycled or removed profitability and soil fertility changes We compared smallholders’ traditional systems 1year fallow of Andropogonon gayanus yam rotation maizeyam rotation with yambased systems with legumes intercropped Aeschynomene histrix with maizeyam rotation intercropped Mucuna pruriens with maizeyam rotation The production of dry matter tubers shoots nutrients removed or recycled and soil properties were significantly improved on yambased systems with legumes in comparison with traditional systems Year × Treatment interactions influenced significantly the tuber dry matter production Site × Treatment and Treatment × Farmer interactions affected significantly nutrients removed or recycled The amount of nutrients recycled or removed was dependent on the dry matter production that in turn depended on soil fertility rainfall and farmers’ effectYambased systems with legumes brought a higher present value than traditional systems in the first 4 years and appeared attractive for land labour and cash productivitiesThe authors express their sincere appreciation and thanks for the financial support received from the French Agency for Development AFD in the framework of the Support Project for Farm Household development PADSE the Development Project for Roots and Tubers PDRT the Food and Agriculture Organisation of the United Nations FAO in the frame of the project TCP/BEN 3002 A entitled “Sustainable production of yams adapted to the markets” the International Cooperation Center in Agronomic Research for Development CIRAD the Cooperation Project for Academic and Scientific Research CORUS the French Embassy in Benin the International Institute of Tropical Agriculture IITAIbadan and the International Atomic Energy Agency IAEA Finally our greatest appreciation goes to farmers who freely agreed to participate in trials and make part of their fields available for the research Their active participation is also highly appreciated
