The Green Revolution was a significant agricultural initiative that aimed to increase agricultural productivity in India. It involved the adoption of modern agricultural techniques such as the use of high-yielding varieties of seeds, irrigation, fertilizers, and pesticides.
Option 1 suggests that the Green Revolution was most successful in Punjab and Tamil Nadu. While Punjab was indeed a major state where the Green Revolution had a significant impact, Tamil Nadu did not witness the same level of success in terms of productivity improvement.
Option 3 suggests that the Green Revolution was most successful in Haryana. While Haryana did experience a positive impact from the Green Revolution, it was not the only state that saw substantial improvements.
Option 4 suggests that the Green Revolution was most successful in Uttar Pradesh and Maharashtra. While these states did see some improvements in agricultural productivity, they were not at the same level as Punjab, Haryana, and Uttar Pradesh.
Therefore, option 2 - Punjab, Haryana, and Uttar Pradesh - is the most accurate answer as these states experienced the highest level of success and impact from the Green Revolution in terms of increased agricultural productivity.
