Question

Green Revolution has been most successful for:
1. wheat
2. rice
3. gram 
4. maize

Answer 1

Correct Answer - Option 1 : wheat

The Correct Answer is "wheat".

• The green revolution is the great increase in the production of food grains (especially wheat and rice).
• It resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century.
• Its early dramatic successes were in Mexico and the Indian subcontinent.
• The new varieties require large amounts of chemical fertilizers and pesticides to produce their high yields, raising concerns about cost and potentially harmful environmental effects.
• Poor farmers, unable to afford the fertilizers and pesticides, have often reaped even lower yields with these grains than with the older strains, which were better adapted to local conditions and had some resistance to pests and diseases.

 

• The Green Revolution, or the Third Agricultural Revolution, is the set of research technology transfer initiatives occurring between 1950 and the late 1960s, that increased agricultural production worldwide, beginning most markedly in the late 1960s.
• The initiatives resulted in the adoption of new technologies, including high-yielding varieties (HYVs) of cereals, especially dwarf wheat and rice.
• It was associated with chemical fertilizers, agrochemicals, and controlled water-supply (usually involving irrigation), and newer methods of cultivation, including mechanization.
