The correct answer is: a) Rice-Wheat.
Punjab is a state in northwestern India. It is known for its fertile land and its agricultural production. The dominant cropping pattern in Punjab is rice-wheat. Rice is grown during the Kharif season (June-October), while wheat is grown during the Rabi season (November-March).
Rice is a staple food in Punjab. It is a cereal grain that is grown in flooded fields. Rice is a good source of carbohydrates, protein, and fiber. It is also a good source of vitamins and minerals, such as thiamin, niacin, and iron.
Wheat is another staple food in Punjab. It is a cereal grain that is grown in dry fields. Wheat is a good source of carbohydrates, protein, and fiber. It is also a good source of vitamins and minerals, such as thiamin, niacin, and iron.
The rice-wheat cropping pattern is a major contributor to the agricultural economy of Punjab. It is a highly efficient system that produces a large amount of food. However, the rice-wheat cropping pattern also has some negative environmental impacts. The use of irrigation water and fertilizers can lead to water pollution and soil degradation.
In recent years, there has been a growing interest in alternative cropping patterns in Punjab. Some farmers are experimenting with growing crops such as maize, mustard, and cotton. These crops are less water-intensive than rice and wheat, and they can help to reduce soil degradation.
The future of agriculture in Punjab will depend on the development of sustainable cropping patterns. Farmers will need to find ways to produce food without damaging the environment.
