Crop residues are vital resources for improving the productivities of cereal-legume-livestock systems in savannahs of West Africa. The competing demands for their uses as fodder or soil amendments present a tradeoff between increasing crop yields and sustaining livestock productivity. An agricultural sustainability framework was used to evaluate the ecological benignity, economic viability, social acceptability and sustainability of five crop residue allocation options at Cheyohi (Ghana), Sarauniya (Nigeria) and Garin Labo (Niger). The crop residue allocation options were: 0, 25, 50, 75 and 100% of haulm with 0, 75, 50, 25 and 100% of stover, respectively, as soil amendment or fodder. The ecological benignity was assessed on the basis of the impact of the allocation option on soil quality, performance of crops and livestock. Indicators such as net benefit from crop or livestock units of the farm and the value cost ratio for the allocation option were used to estimate the economic viability. The indicators used to appraise the social acceptability were the indigenous knowledge of farmers on the alternative uses of crop residues, the perceived constrain ... 전체 초록 보기
