    This investigation is falls within the framework of conservation agriculture. Indeed, twenty-five years after the first of zero tillage farming experiences, this new method was named crop conservation agriculture because it helps preserve soil nutrients, water absorption enhancing and infiltration and biodiversity by maintaining the natural equilibrium in the soil. The objective of this work is the study of the impact of tillage (conventional work and direct sowing) on water properties of the soil, especially the water-holding capacity of the soil in semi arid zone (case of Tiaret region). According to the results, the comparative analysis between the two types of tillage (direct drilling and conventional tillage) shows that water studied parameters such as moisture equivalent (He), of holding capacity (Cr) wilting point (Pf) and AWR (UK) are higher in the case of direct seeding than in the case of conventional labor Â
