The study analyzes the short-term effect of tillage systems on soil physical properties, spectral response and sunflower yield, was based on three tillage system NT (No-tillage); MT (Minimum tillage); and CT (Conventional tillage). Data collected include soil physical properties (PR: Penetration resistance, VWC-Soil water content, Ks-Soil hydraulic conductivity), crop’s spectral response through different multispectral sensors, and yield. Results showed that the for Ks, the highest value was obtained with NT at depth 0-10 cm. Concerning PR, high values were respectively recorded with CT (3.54 Mpa) during the vegetative period of the plant and with MT (2.54 MPa) during the harvesting period. Grain yields were also influenced by the tillage systems and reached values of 2.105, 2.631 and 3.052 kg/ha, respectively for the NT, MT and CT systems. Yield was also affected by heavy draught.
