What change was observed in agricultural practices after the Green Revolution?

Correct option is C

The Correct Answer is C: Shift from low-yield to high-yield crops

Explanation:
The Green Revolution introduced high-yielding variety (HYV) seeds, improved irrigation, and increased the use of chemical fertilisers and pesticides. This led to a shift from traditional low-yield crops to high-yield varieties, significantly boosting food grain production, especially wheat and rice.

Key Points:

• Introduced high-yielding varieties (HYVs) to enhance productivity.
• Increased use of fertilisers and pesticides for better crop output.
• Expansion of irrigation facilities to support intensive farming.
• Mechanisation of agriculture with modern equipment like tractors and harvesters.

Additional Information:

• Monoculture of wheat only is incorrect; the revolution also impacted rice and other grains.
• Shift from cash crops to subsistence farming is inaccurate; the focus remained on commercial food production.
• Decrease in the use of fertilisers is incorrect; fertiliser use actually increased significantly.
