What do crops of the green revolution need in order to produce high yields?

Crops of the Green Revolution require a combination of high-yielding varieties (HYVs), adequate water supply through irrigation, and the application of chemical fertilizers and pesticides to maximize growth and protect against pests and diseases. Additionally, optimal agricultural practices, such as crop rotation and proper field management, are essential to sustain productivity. Access to modern farming equipment and technology also plays a crucial role in achieving high yields.
