Agriculture
Focused last-minute revision with clear concepts, high-yield comparisons, diagrams, exam traps and compact practice.
Chapter Snapshot
- Agriculture is a primary activity involving cultivation of crops and often livestock.
- Farming systems depend on land, labour, capital, climate, technology and market access.
- Subsistence farming mainly meets family needs; commercial farming mainly produces for sale.
- Crop distribution reflects temperature, rainfall, soil and market conditions.
- A farm can be studied as a system of inputs, processes and outputs.
- Agricultural development aims to improve productivity, efficiency and sustainability.
What You Will Learn
- Explain agriculture as a primary activity
- Distinguish subsistence and commercial farming
- Identify intensive, primitive and plantation farming
- Relate major crops to climatic conditions
- Explain farm inputs, processes and outputs
- Understand agricultural development and productivity
Last-Minute Chapter Map
Revise this chapter in three passes:
- Understand the key geographical idea.
- Memorise comparisons, terms and cause–effect links.
- Attempt the compact questions without looking at the answers.
1. Agriculture as a Primary Activity
2. Farm as a System
A farm can be understood as a system. Inputs include seeds, fertiliser, machinery, labour, capital and water. Processes include ploughing, sowing, irrigation, weeding and harvesting. Outputs include crops, livestock products and income. Weather, market prices and technology influence the system.
3. Subsistence Farming
Subsistence farming mainly aims to satisfy the needs of the farmer's family. It may use small landholdings and family labour. Primitive subsistence farming may involve simple tools and small plots. Intensive subsistence farming uses high labour and inputs on limited land to obtain more production.
4. Commercial Farming
Commercial farming produces mainly for sale in markets. It may use modern machinery, improved seeds, irrigation and chemical or organic inputs. Farm size varies by region. Plantation agriculture is a form of commercial farming usually specialising in a single major crop such as tea, coffee, rubber or sugarcane over a large organised estate.
5. Major Food Crops
Rice generally needs warm conditions and abundant water, especially during growth. Wheat prefers a cooler growing season and bright sunshine during ripening. Maize grows in a wide range of climates with adequate warmth. Millets are important in many drier regions and can tolerate relatively low rainfall.
6. Fibre, Beverage and Other Crops
Cotton generally needs warmth and a long frost-free period. Jute needs warm, humid conditions and abundant water. Tea grows well in warm, wet climates on well-drained slopes; coffee also requires suitable temperature, rainfall and elevation conditions. Crop requirements vary with variety and local farming practice.
7. Agricultural Development
Agricultural development means improving farm productivity and farmer well-being through better seeds, irrigation, soil care, machinery, storage, transport, research and access to markets. Sustainable agriculture also aims to protect soil, water and biodiversity.
Types of Farming
| Type | Main Aim | Typical Features |
|---|---|---|
| Subsistence | Family needs | Smaller output for direct use |
| Intensive subsistence | High output from limited land | High labour and input use |
| Commercial | Sale in markets | Market orientation and often greater capital use |
| Plantation | Commercial production of one major crop | Large organised estates and processing links |
Selected Crop Conditions
| Crop | Broad Conditions |
|---|---|
| Rice | Warm, wet conditions; abundant water |
| Wheat | Cooler growing season; sunshine during ripening |
| Millets | Can grow in relatively drier conditions |
| Jute | Warm, humid and high rainfall |
| Tea | Warm, wet climate; well-drained slopes |
A farm operates as a system connecting environmental and human inputs with agricultural outputs.

Compact Practice
Plantation agriculture is mainly which type?
View Solution
Commercial farming
Which crop is strongly associated with warm and very wet conditions?
View Solution
Rice
What are farm inputs?
View Solution
Resources used in farming, such as seeds, labour, machinery, water and fertilisers.
Differentiate subsistence and commercial farming.
View Solution
Subsistence farming mainly meets household needs; commercial farming mainly produces for market sale.
Why can irrigation and storage both increase farm income?
View Solution
Irrigation can stabilise production, while storage reduces post-harvest loss and allows better marketing.
