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 the ground various parameters (the ground humidity). And farming parameters output such as the rate of survey, the adventitious infestation and the corn grains yield and these components. The experimental device including the technical factor farming on three levels: zero tillage or direct seeding (DS), conventional tillage (CT) and simplified cultural technique (SCT) or minimum tillage (TM) and only one cereal species. The positive hydrous assessment in zero tillage and also yield components and the grain yield. The zero tillage, in addition to its advantages as regards evaporation reduction, makes it possible to fix well the cereal cycle. It also makes it possible the culture to benefit from the first year rains and to escape the dryness's from end from cycle. The application finality of this study is to mitigate some causing effects climate warming. (C) 2015 The Authors. Published by Elsevier Ltd.
