The correct answer is: d) All of the above
Nagaland is a state in northeastern India. It is a mountainous state with a population of over 1.9 million people. The majority of the population is Naga, a group of indigenous peoples.
Rice is the staple food of Nagaland. It is grown in a variety of environments, including hilly areas, valleys and plains, and semi-arid regions.
Hilly areas: Rice is grown in hilly areas by terracing the land. This involves building a series of steps on the hillside to create a flat surface for planting. The terraces are then irrigated with water from streams or rivers.
Valleys and plains: Rice is also grown in valleys and plains. In these areas, the land is relatively flat and there is plenty of water available for irrigation.
Semi-arid regions: Rice is also grown in semi-arid regions. In these areas, the land is dry and there is less water available for irrigation. However, rice can be grown in these areas by using a technique called dryland rice cultivation. Dryland rice cultivation involves planting rice in areas where there is less than 500 mm of rainfall per year. The rice plants are then irrigated with water from wells or tanks.
Rice is an important part of the Naga economy. It is a major source of food and income for the people of Nagaland.
