🌾 Introduction to Agriculture

• Until around 10,000 B.C.E., humans led a nomadic lifestyle, wandering from one place to another in search of food and shelter.
• They ate raw fruits and vegetables, and later began hunting animals for food.
• Over time, they discovered how to cultivate land—growing crops like rice, wheat, barley, etc.
• This marked the beginning of agriculture, transforming human society from food gatherers to food producers.

🌿 What is a Crop?

• A crop is defined as plants of the same kind grown at one place on a large scale.
• ✅ Example: A field filled with only wheat plants is called a wheat crop.

🥕 Types of Crops Based on Seasons

India’s climate varies across regions, resulting in different cropping patterns.

🌧️ (i) Kharif Crops

• 🌱 Sown: Beginning of rainy season (June)
• 🌾 Harvested: End of rainy season (September/October)
• 🌾 Examples:
  • Paddy (rice)
  • Maize
  • Soyabean
  • Groundnut
  • Cotton

❄️ (ii) Rabi Crops

• 🌱 Sown: Beginning of winter (October)
• 🌾 Harvested: March/April
• 🌾 Examples:

🌾 Difference Between Kharif and Rabi Crops (CBSE Exam Important Question)

📘 Summary

• Kharif crops are monsoon crops, grown during June to October.

❓ Conceptual Questions with Answers

Q1: Why are crops classified based on seasons?

Ans: Crops require specific temperature, rainfall, and humidity for proper growth. Since these vary by season, crops are classified accordingly.

Q2. Why are crops divided into Kharif and Rabi types?

Ans: Because different crops require different climatic conditions—like temperature and rainfall—available in specific seasons.

Q3. Why does rice grow well in the Kharif season?

Ans: Rice requires a lot of water, and Kharif coincides with the monsoon season, providing abundant rainfall.

Q4: What is the importance of Kharif and Rabi crops in Indian agriculture?

Ans: These crops ensure year-round food supply and economic stability for farmers.
