The main purpose of tillage in crop production is weed control. Tillage helps to manage weeds by disrupting their growth and lifecycle. By turning the soil and bringing buried weed seeds to the surface, tillage exposes them to unfavorable conditions, promoting their decay and reducing their competition with crops. This process can also incorporate crop residues into the soil, which can further deter weed establishment while improving overall soil health.

While tillage may also contribute to increased crop yields indirectly by creating a favorable seedbed and enhancing water infiltration, its primary function centers around managing weeds effectively. Other options such as soil erosion and soil compaction are typically considered negative effects of improper tillage practices rather than its main objectives.
