A significant portion of Manipur’s agriculture is:

Rainfed
Irrigated
Plantation-based
Mechanized

The correct answer is: Rainfed.

Manipur is a landlocked state in northeastern India. It is bordered by Nagaland to the north, Assam to the west, Mizoram to the south, and Myanmar to the east. The state has a population of over 2.8 million people.

The economy of Manipur is based on agriculture, forestry, and tourism. Agriculture is the main source of livelihood for the majority of the population. The main crops grown in Manipur are rice, maize, wheat, sugarcane, and vegetables.

The state receives an average annual rainfall of about 2,000 mm. The monsoon season is from June to September. The rest of the year is dry.

The majority of agriculture in Manipur is rainfed. This means that the crops are grown without the use of irrigation. Rainfed agriculture is more vulnerable to droughts and floods.

Irrigated agriculture is a type of agriculture where water is supplied to the crops through artificial means, such as canals, wells, or pumps. Irrigated agriculture is more productive than rainfed agriculture. However, it is also more expensive.

Plantation-based agriculture is a type of agriculture where crops are grown on large plantations. Plantations are often owned by large corporations. Plantation-based agriculture is common in tropical countries.

Mechanized agriculture is a type of agriculture where machines are used to perform most of the agricultural tasks. Mechanized agriculture is more productive than traditional agriculture. However, it is also more expensive.

In conclusion, the correct answer to the question “A significant portion of Manipur’s agriculture is:” is “Rainfed.”
