Any tillage system modifies the soil structure and, depending on the edaphic aspects, mechanization favors or destroys the structure, affecting the growth and development of the crop.
▶ This is affirmed by what was demonstrated in the data collection, where there was no statistical difference in the level of anchorage of the root system and therefore in the development of the crop under study.

The use of the mechanized direct tillage system is recommended for large sowing extensions and manual direct sowing for small plots, since there is no difference with the other tillage methods in better conditions for root development and therefore for the crop.
It is suggested to alternate tillage systems, depending on the type and level of soil compaction, starting with tillage with a moldboard plow and then sowing directly, thus reducing damage to the biotaedaphics.
Therefore, it is advisable for producers to carry out direct sowing, due to the reduction of mechanization expenses for land preparation, which would only generate costs for manual sowing or mechanized sowing.
It is recommended that producers who opt for conventional or traditional mechanization reduce herbicide application costs and use moldboard plowing to establish the crop without weeds, since this type of tillage produces greater root anchorage and reduces the proliferation of weeds.
