In the context of the climate changes, the cereals’ culture appears relatively vulnerable because of some of his characteristics, as well physiological as socio-economic. Uncertain rain agriculture in the semi-arid and arid areas and their need hydrous annual negatively affects the production and the output in grains. The study of ground various parameters (humidity) and farming parameters output such as the survey rate, adventitious infestation and corn grains yield and these components. The experimental device including technical factor farming on three levels: zero tillage (or direct seeding) (DS), conventional tillage (CT) and simplified cultural technique (SCT) (or minimum tillage) (TM) for only one cereal species. Soil moisture, yield components and grain yield were higher in zero tillage. In addition to its benefits for evaporation reduction, direct seeding allows caller the cereals cycle. It also makes it possible at the culture to benefit from the first year rains and to escape the dryness from end from cycle. The application finality of this study is to mitigate some causing effects climate warming. |
