Part 1: Basics of Agriculture & Crops
▪ Agriculture: Definition, Importance, History
Definition: Agriculture is the science and practice of cultivating the soil, growing crops, and
raising livestock to produce food, fiber, and other products essential for life.
Agriculture marks the shift from hunter-gatherer life (Neolithic Age) to settled
civilization.
India is an agricultural powerhouse, with diverse cropping patterns due to varied climates
and soils.
Agriculture’s role:
o Economic Backbone (provides employment).
o Food Security (grains, pulses, fruits, vegetables).
o Raw Materials for industries (cotton for textiles, sugarcane for sugar).
, ▲ What is a Crop?
A crop is a group of plants of the same species cultivated in a field at a large scale for
commercial purposes.
Examples:
o Food crops: Wheat, Rice.
o Fiber crops: Cotton, Jute.
o Oilseeds: Mustard, Groundnut.
o Fodder crops: Sorghum, Berseem.
Crops are classified based on use, growing season, water requirement, and climate
adaptability.
● Types of Crops (Seasonal Classification)
1. Kharif Crops:
o Sown: June–July (start of monsoon).
o Harvested: September–October.
o Climate: Warm and wet.
o Examples: Paddy, Maize, Cotton, Soybean.
2. Rabi Crops:
o Sown: October–November.
o Harvested: March–April.
o Climate: Cool, dry growth period; mild summer at harvest.
o Examples: Wheat, Barley, Mustard, Pea.
3. Zaid Crops:
o Sown: Between Rabi and Kharif (March–June).
o Examples: Watermelon, Cucumber, Muskmelon.
📌 Olympiad Tip: Match crop name with season + climate; this is a common question format.
★ Cropping Patterns
1. Monocropping:
o Growing a single crop repeatedly in the same field.
o Risk: Soil nutrient depletion, pest attack vulnerability.
2. Mixed Cropping:
o Growing two or more crops together without a fixed row pattern.
o Advantage: Minimizes total crop failure risk.
3. Intercropping:
o Crops grown in a specific row arrangement to maximize space & nutrients.
o Example: Maize + Soybean.
4. Crop Rotation:
o Growing crops in planned succession to restore soil nutrients.
o Example: Cereals → Legumes (adds nitrogen).
💡 Hinglish Deep Insight:
“Socho agar hum bar-bar ek hi crop lagayenge (monocropping), toh soil ke nutrients khatam ho
jayenge. Crop rotation ek natural fertilizer ka kaam karta hai kyunki legumes nitrogen fix karte hain.
Ye Olympiad ke liye bahut hi common tricky question hai.”
■ Factors Affecting Agriculture
Soil Type: Determines crops (Black soil → Cotton; Alluvial → Rice, Wheat).
Climate: Temperature, rainfall decide crop choice.
Irrigation: Water availability is crucial in arid zones.
Technology: Use of machinery, HYV seeds, fertilizers boosts production.
