In wheat growing, one may apply technologies with a reduced number of works without influencing significantly the yield level. Both the weight of 1000 grains and the hectolitric weight in wheat where not significantly influenced by the application of the technologies of reduced soil works, but it was remarked a decrease tendency of these values once with the decrease of the working depth and the diminuation of the soil mobilization degree. Soil physical and physical-mechanical properties were modified under the influence of soil works. Soil aeration porosity and structure total hydrical stability decreased at the same time with the decrease of the working depth and the diminution of soil mobilization degree, while the apparent density and the soil penetration resistance increased. There were noticed significant and distinct significant correlation between elements of production and soil physical and physical-mechanical characteristics.
