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.
