Correct answer
West Bengal
Why this answer is correct
The correct answer is West Bengal.
Key Points
- In India, particularly in states like West Bengal, Assam, and Odisha, the prevailing climatic conditions allow for the cultivation of three distinct crops of rice within a single agricultural year.
- The three varieties are identified based on their seasonal cycles and are locally named Aus, Aman, and Boro.
- Aman is the primary winter rice crop. It is typically sown during the onset of the Southwest Monsoon in June and July and harvested between November and December. It occupies the largest portion of the total rice area in the state.
- Aus is referred to as autumn rice. It is sown during the pre-monsoon period in May and June and harvested in the autumn months of September and October.
- Boro is known as summer rice. This variety is sown in the winter (November to January) and harvested in the summer (April to May). Its cultivation is heavily reliant on assured irrigation facilities during the dry season.
- The fertile alluvial soil and the hot, humid climate of the lower Gangetic plains in West Bengal provide the ideal environment for this intensive cropping pattern.
Additional Information
- Rice (Oryza sativa):
- It is the staple food crop for a significant majority of India’s population and is primarily a Kharif crop.
- Growth requires high temperatures (above 25°C), high humidity, and annual rainfall exceeding 100 cm.
- West Bengal is consistently among the top producers of rice in India, contributing significantly to the national food security.
- Geographical Context of Other Options:
- In Manipur and Nagaland, rice is often grown using Jhum (shifting) cultivation or terrace farming in hilly terrains, where a single crop is more common due to topographical constraints.
- While Bihar is a major rice producer, the specific nomenclature and systematic triple-cropping of Aus, Aman, and Boro are most traditionally associated with the Bengal delta region.
