Résumé : Direct seeding mulch-based cropping systems have first been adopted to fight soil degradation caused by wind or water. Different systems have then been developed to face the range of constraints from humid tropical to semi-arid areas, in small farming environment as well as in high-mechanized agriculture. The best direct seeding on plant cover systems (DMC: direct seeding mulch-based systems, conservation tillage) can rapidly restore soil fertility, maximise the use of the available water and control weeds at a lower cost. It gives responses to farmers who aim at a higher profitability, an easier and simplified labour, and perspectives to the global need for a sustainable development and the preservation of natural resources. A generic approach can be defined to build new systems in different ecological and socioeconomic contexts: various hypothesis drawn from a multidisciplinary diagnosis are tested in matrices, i.e. system trials in which several key factors are combined. The Matrices are sites of research, innovation, and training. The involvement of farmers in the elaboration of those systems contributes greatly to their extension: the continuous assessment along with them help establish and further develop the systems to meet their specific needs.
