Crop rotations that include temporary grassland can effectively control weeds without the need for herbicides, leading to sustainable crop production. A study in Brazil compared a grassland-cropping rotation with a crop-based rotation and found that the grassland rotation significantly reduced weed interference in maize, resulting in higher crop yields. The grassland rotation suppressed weeds better, leading to fewer weeds in the early stages of maize growth compared to the crop-based rotation. This approach prevents the selection of weeds that can cause significant yield losses in maize, making it a cost-effective alternative for weed management in agriculture.
