Green revolution referes to increased production of

Options

A. Green plants
B. Pulses
C. Milk
D. High yield variety crops

Answer

**Step-by-Step Solution:**

1. **Understanding the Green Revolution**: The Green Revolution refers to a significant increase in agricultural production, particularly in developing countries, due to the introduction of high-yielding varieties (HYVs) of crops, improved agricultural practices, and the use of fertilizers and irrigation.

2. **Time Frame**: The period commonly associated with the Green Revolution is from the 1960s to the 2000s. During this time, many countries, especially in Asia and Latin America, experienced substantial increases in food production.

3. **Key Crops**: The primary crops that saw increased production during the Green Revolution were wheat and rice. These staples are crucial for food security in many parts of the world.

4. **Statistical Evidence**:
- Wheat production in India increased from 11 million tonnes to 75 million tonnes.
- Rice production rose from 35 million tonnes to 89 million tonnes.
This dramatic increase in production was largely due to the development of semi-dwarf varieties of these crops.

5. **Role of Scientists**: Norman E. Borlaug, a prominent scientist, played a pivotal role in the Green Revolution by developing semi-dwarf wheat varieties at the International Center for Wheat and Maize Improvement in Mexico. His work significantly contributed to the increased yields of wheat.

6. **Examples of High-Yielding Varieties**:
- An example of a high-yielding wheat variety is Kalyan Sona, which is known for its high yield and disease resistance.
- Similar advancements were made in rice varieties, which also contributed to the overall increase in food production.

7. **Conclusion**: The Green Revolution primarily refers to the increased production of high-yielding variety crops, particularly wheat and rice, which were developed through scientific advancements and agricultural practices.

**Final Answer**: The Green Revolution refers to the increased production of high-yielding variety crops, especially wheat and rice.
