Which of these practices can help manage weeds effectively?

Diverse crop planting is an effective practice for managing weeds because it enhances crop rotation and encourages biodiversity in the field. By planting a variety of crops, farmers can disrupt the life cycles of weeds, making it harder for them to establish and proliferate. Different crops may compete for resources in distinct ways, which can suppress weed growth. Additionally, diverse cropping systems can attract beneficial organisms that help in controlling weed populations.

This approach also reduces the reliance on herbicides, which can lead to resistance issues if used exclusively or in a repetitive manner. It promotes a more sustainable agricultural system by improving soil health, reducing pest pressures, and fostering a balanced ecosystem, ultimately leading to better crop yields and reduced weed competition.
