Crop yield has increased.

Meta-analyses and many field studies show that widely planted GE traits (especially Bt insect‑resistance and herbicide tolerance) have raised average yields — by roughly 10–25% in many studies overall — mainly by reducing insect damage and improving weed control and crop management. Effects vary by crop, trait, location and management, so local results can be smaller or larger.
