Which crop is extensively cultivated in the fertile alluvial soils of Arunachal Pradesh?

Rice
Wheat
Maize
Tea

The correct answer is: a) Rice

Rice is the most important crop in Arunachal Pradesh, accounting for over 80% of the state’s cultivated area. It is grown in both the hilly and the plain areas of the state. The main rice-growing areas are the Brahmaputra valley, the Subansiri valley, and the Lohit valley.

Rice is a tropical crop that requires a warm and humid climate. The ideal temperature for rice cultivation is 25-30 degrees Celsius. The crop also requires a lot of water, and is usually grown in flooded fields.

Rice is a major source of food for the people of Arunachal Pradesh. It is also used to make a variety of other products, such as rice flour, rice wine, and rice paper.

The other options are incorrect because:

  • Wheat is a temperate crop that does not grow well in the tropical climate of Arunachal Pradesh.
  • Maize is a drought-tolerant crop that is not as well-suited to the humid climate of Arunachal Pradesh.
  • Tea is a plantation crop that is grown in specific areas of the state, and is not as widely cultivated as rice.
