Comparative Study of the Effect of Direct Seeding, Conventional Tillage and Simplified Cultural Work on the Behavior of a Wheat Crop (Triticum Durum)
The direct seeding system is an alternative to traditional farming, which has proven unsuitable for new climate and economic data of competitiveness and sustainability (Elbrahli, 2009). In addition to the economic, working time and energy advantages, direct seeding techniques are a new agronomic approach aimed at developing or even restoring the soil to natural fertility. This improvement in soil fertility it based on an organic and biological revitalization of soils and a restructuring of its surface, which instead of being sensitive to degradation will become a support for sustainable agriculture (Mrabet et al, 2005). Improving techniques based on the restoration and conservation of organic matter is a preferred option for the regeneration of soil fertility. (Bock et al, 2005). The adoption of simplified cultivation techniques and direct seeding would allow the efficient preservation of natural resources and the environment, and their dissemination must take into account the diversity of the production environment, its constraints and the role played by the cereal sheep farming. It also aims to identify the many facets of these conservation techniques that help and reinforce the sustainability of agriculture. (Zaghouane et al, 2006).
Objective: To highlight the possibility of using direct seeding in wheat management by ensuring acceptable productivity while respecting the principle of sustainable agriculture (conservation agriculture)
