In the period 2002-2005 it was studied the effect of the soil ploughing depth for sunflower on soil humidity regulation and yields. It was tested two ploughing tillad on depth 23-25 cm and 31-33 cm. The results present that the deeper ploughing on 31-33 cm increases total water supplay quantity of water productivity in soil and yields of sunflower. The effect of ploughing tillage on depth 31-33 cm with respect to water productivity continues to flowering phase. Yields are increased with 165 kg/da.
