Auteurs : Chennafi Houria .
Résumé
The potential expression of wheat is related to environmental conditions, mostly tributary on water constraint. Besides, deficit irrigation, the genotype performance associated to environmental management of the plant improves the water use efficience. Indeed, in the medium where water is scarce, the preservation in root zone of a limited amount of water by suitable practice of soil reduces the effect of the advent of a water scarcity at sensible vegetative stage. The approach is based on agricultural development oriented on reducing of the disturbance of soil associated to the use of natural resources in a sustainable improvement.
