In no-tillage (NT) system, precedent crop residue retains on the soil surface to preserve soil water for crop growth. In response to the negative impact of soil degradation under conventional tillage (CT) system based on soil tillage, NT system without tillage practice and with protective cover of crop residue is being developed in many parts of the world. However, NT is a successful system especially in the South of America, but the impacts of this system on the Mediterranean climate especially in the southeast (SE) of France is less known; therefore, this study has been carried out within the scope of a European project. Durum wheat and corn were sown under CT and NT. Time requirement and fuel consumption in these two systems were measured. The results showed that durum wheat and corn yields were the same in both systems except of 2008, while work duration and energy requirement were 87% and 83% lower in NT system, respectively. Furthermore, NT could mitigate CO ₂ emission up to 50% as compared with CT. These results show that NT can be considered as a relevant alternative for CT regarding economical and environmental advantages.
