3. Both are essential for food security and global agriculture.

2. Importance of Cereals

1. Cereals are the staple food for a large part of the world's population.
2. They provide energy, fiber, vitamins, and minerals.
3. They have multiple industrial uses, including flour, alcohol, and biofuels.

3. Major Cereals and Their Importance

A. Wheat (Triticum spp.)

1. Wheat is a major temperate crop and a primary source of bread and pasta.
2. It is rich in carbohydrates and contains moderate amounts of proteins.
3. Leading producers: India, China, USA, Russia.
4. Wheat flour is used for making bread, biscuits, cakes, and chapatis.

B. Rice (Oryza sativa)

1. Rice is a staple food for over 50% of the world’s population.

C. Maize (Zea mays)

1. Also known as corn, maize is a globally important cereal.
2. It is used for human consumption, animal feed, and industrial purposes.
3. It contains high amounts of carbohydrates and moderate amounts of proteins and fats.
4. Major producers: USA, China, Brazil, India.
5. Maize is used in popcorn, cornflakes, ethanol production, and fodder.

4. Importance of Pulses

1. Pulses are a major source of plant-based proteins.
2. They are rich in fiber, vitamins, minerals, and essential amino acids.
3. Pulses improve soil fertility by fixing nitrogen through symbiotic bacteria.
4. Common pulses include lentils, chickpeas, peas, beans, and pigeon peas.

5. Major Pulses and Their Importance

A. Chickpea (Cicer arietinum)

1. Rich in proteins, fiber, and iron.
2. Used in making dal, hummus, and flour.

B. Lentils (Lens culinaris)

1. One of the oldest cultivated pulses.
2. Rich in proteins and essential amino acids.
3. Major producers: Canada, India, Turkey.

C. Pigeon Pea (Cajanus cajan)

1. Also known as Arhar or Toor dal in India.
2. Used in making traditional Indian dishes.
3. Fixes atmospheric nitrogen, improving soil fertility.

D. Black Gram (Vigna mungo)

1. Used in making idli, dosa, and dal makhani.
2. Rich in proteins, iron, and calcium.
3. Major producers: India, Myanmar.

6. Economic and Agricultural Importance

1. Cereals and pulses form the basis of the global food economy.
2. They provide employment to millions of farmers worldwide.
3. They contribute to the GDP of many agricultural countries.

7. Challenges and Future Prospects
