The correct answer is: Rainfed.
Manipur is a state in northeastern India. It is a landlocked state with a population of over 2.8 million people. The state is known for its natural beauty, its rich culture, and its diverse ethnic groups.
Agriculture is the main occupation in Manipur. The state has a humid subtropical climate with two distinct seasons: a wet season from June to September and a dry season from October to May. The average annual rainfall is about 1,200 mm.
The main crops grown in Manipur are rice, maize, wheat, sugarcane, and pulses. The state also has a significant livestock population, including cattle, buffalo, pigs, and poultry.
A significant portion of Manipur’s agriculture is rainfed. This means that the crops are grown without the use of irrigation. Rainfed agriculture is more vulnerable to drought and other weather conditions than irrigated agriculture. However, it is also less expensive and requires less infrastructure.
Irrigated agriculture is the practice of using artificial means to water crops. This can be done through a variety of methods, such as canals, wells, and sprinklers. Irrigated agriculture is more productive than rainfed agriculture, but it is also more expensive and requires more infrastructure.
Plantation-based agriculture is the practice of growing crops on large, single-crop farms. Plantation crops are often cash crops, such as tea, coffee, and rubber. Plantation-based agriculture is common in developing countries, where it can provide employment and income for rural communities. However, it can also have negative environmental impacts, such as deforestation and soil erosion.
Mechanized agriculture is the practice of using machines to perform agricultural tasks, such as planting, harvesting, and threshing. Mechanized agriculture is more efficient than manual agriculture, but it also requires more capital investment.
In conclusion, the correct answer to the question “A significant portion of Manipur’s agriculture is: Rainfed / Irrigated / Plantation-based / Mechanized” is Rainfed.
