Correct option is D
The correct answer is (d) Use of organic manures.
The new agricultural strategy, often referred to as the Green Revolution, primarily focused on the following characteristics:
o Use of chemical fertilizers: These were introduced to enhance crop yields and provide necessary nutrients to the soil.
o Use of hybrid seeds: High-yield variety (HYV) seeds were developed and used to increase crop production significantly.
o Extensive irrigation: Large-scale irrigation projects and methods were implemented to ensure a reliable water supply for crops.
Organic manures: This is not a characteristic of the new agricultural strategy. Instead, the focus was on chemical fertilizers for quick and substantial improvements in crop yield. Organic manures are more aligned with traditional and sustainable farming practices, which emphasize long-term soil health.
