Correct Option
The correct option is The success of the Green Revolution.
Explanation
Rabi crops are sown in winter (October to December) and harvested in summer (April to June). Important Rabi crops include wheat, barley, peas, gram, and mustard. The agricultural output of North-Western India was fundamentally transformed by technological interventions introduced in the mid-1960s.
Option Analysis
- The success of the Green Revolution. is Correct: The Green Revolution was instrumental in transforming agriculture in Punjab, Haryana, and Western Uttar Pradesh. The introduction of High-Yielding Variety (HYV) seeds, mechanization, and the development of assured irrigation infrastructure (tubewells and canals) allowed these regions to maximize the production of Rabi crops, particularly wheat.
- High humidity during the ripening season. is Incorrect: Rabi crops generally require a cool climate during the growing season and bright sunshine with dry conditions during ripening. High humidity during the ripening season is detrimental to crops like wheat, as it increases susceptibility to pests and fungal diseases.
- Heavy rainfall from the Southwest Monsoon. is Incorrect: The Southwest Monsoon occurs from June to September and primarily supports Kharif crops. While the moisture retained in the soil helps, Rabi crops in winter rely mainly on irrigation and precipitation from Western Disturbances, not the Southwest Monsoon.
- The use of traditional seeds. is Incorrect: The surge in growth was driven by the shift from traditional seeds to High-Yielding Variety (HYV) seeds. Traditional seeds generally have lower yields compared to the scientifically developed varieties used during the Green Revolution.
Key Takeaway
The dominance of Punjab, Haryana, and Western Uttar Pradesh in Rabi crop production is a direct result of the Green Revolution, which combined HYV seeds, fertilizers, and irrigation to ensure high productivity.
