Abstract: 

Agriculture has an important role in the development of the Beninese economy. Now, the sector has a major change with the agricultural motorization. In order to contribute to the sustainable management of farms, this study evaluated the effect of four motorized ploughing depths on soil structure and vegetative growth of maize. Results show that ploughing at 15 cm depth provides the best agricultural yield and does not adversely affect the physical, mechanical and hydrodynamic characteristics of the soil. The optimum yield is estimated at 2.98 t / ha with a plow depth of 14.66 cm for the DMR-ESR-W variety. The TZEE-W-SR variety was 3.29 t / ha obtained with a plow depth of 14.39 cm.
