Which of the following was true with regard to the Green Revolution?

Correct Answer: It involved use of high-yielding variety of seeds

Explanation:

The Green Revolution in India was initiated in the mid-1960s to increase food grain production and achieve food self-sufficiency in the country. The key components of the Green Revolution included:

1. High-Yielding Varieties (HYV) of Seeds: The introduction of high-yielding varieties of seeds, particularly for wheat and rice, was the main feature of the Green Revolution. These seeds produced much higher crop yields per acre compared to traditional seeds.

2. Chemical Fertilisers and Pesticides: Unlike organic farming, the cultivation of HYV seeds heavily depended on chemical fertilisers, pesticides, and weedicides to achieve optimal output and protect crops from pests.

3. Controlled Water Supply / Irrigation: HYV crops required significantly large and regular quantities of water, making proper irrigation infrastructure essential, rather than relying on less water.

4. Focus Crops: The primary focus of the Green Revolution was on food grains, mainly wheat and rice, rather than pulses.

Therefore, the statement that "It involved use of high-yielding variety of seeds" is true regarding the Green Revolution.
