NDA Geography · Indian Geography — Economy, Resources and Transport
Agriculture, Crops, Soils and Land Use
What India grows and where, the soils it grows in, the cropping seasons, and how the land-revenue records officially classify every parcel of land.
Why this matters
The single largest subtopic in the chapter — around 23 PYQs once the misfiled stems are set aside, leaning EASY-to-MODERATE. The marks cluster in four buckets: the land-use / fallow-land vocabulary (current fallow vs culturable wasteland is asked almost every year), the soil-to-region pairs (black/regur, laterite), the crop conditions and crop-to-state pairs, and the agricultural schemes. Learn the fallow-land thresholds and the regur/laterite facts cold.
Concept 1 of 5: Kharif, Rabi and Zaid — the three cropping seasons
Definition
- Kharif (monsoon, sown Jun–Jul, harvested Sep–Oct) — rice, bajra, jowar, maize, cotton, jute, groundnut. Needs warmth + heavy rain.
- Rabi (winter, sown Oct–Nov, harvested Mar–Apr) — wheat, barley, gram, peas, mustard. Needs a cool growing period and dry, warm ripening.
- Zaid (short summer, Mar–Jun) — watermelon, muskmelon, cucumber, fodder crops.
- A crop's season is the key recall fact: in the Northern States barley is a rabi crop, while rice and bajra are kharif.

Concept 2 of 5: Land-use categories and fallow land
Definition
- Land-Revenue Records classify land into 9 categories of land use.
- Current fallow — left uncultivated for up to one year (a normal rest).
- Fallow other than current fallow — uncultivated for more than 1 year but less than 5 years.
- Culturable wasteland — left fallow for more than 5 years (it has gone out of cultivation but could be reclaimed).
- Barren and waste land — land that cannot be brought under cultivation at all (rocky, desert).
| Term | How long uncultivated | Meaning |
|---|---|---|
| Current fallow | Up to 1 year | A normal one-season rest |
| Fallow other than current fallow | 1 to 5 years | Resting longer than a season NDA repeats this 1-to-5-year band almost every year. |
| Culturable wasteland | More than 5 years | Out of cultivation but reclaimable NDA 2024 (Sep) — fallow for more than five years is culturable wasteland. |
| Barren and waste land | Permanently | Cannot be cultivated |
| (Land-use categories in total) | — | 9 categories |

Concept 3 of 5: Soils of India — black, laterite, alluvial
Definition
- Black / Regur soil — Deccan cotton soil; develops on basaltic lava under hot, SEMI-ARID (dry) conditions; dark coloured, clayey, moisture-retentive; ideal for cotton. (A claim of 'light coloured' or 'hot and humid' is the trap.)
- Laterite soil — forms in hot, wet climates by heavy leaching; rich in iron and aluminium, but poor in nitrogen, lime and phosphate. Of {calcium, nitrogen, phosphate, potash}, it is comparatively rich only in potash.
- Alkaline soils — high sodium, pH above 7.0.
- Bajra grows on sandy / shallow black soils (Rajasthan, UP, Maharashtra); ragi suits red and shallow black soils (Karnataka, Tamil Nadu).
| Soil | Forms under | Best for / key fact |
|---|---|---|
| Black / Regur | Basaltic lava, hot dry climate | Cotton; dark, clayey, retains moisture NDA 2024 — regur is DARK and forms under hot DRY (not humid) conditions. |
| Laterite | Hot wet, heavy leaching | Rich in iron/aluminium; of the nutrients, only potash NDA 2025 (Sep) — laterite is rich in potash, poor in N, P, lime. |
| Alkaline | High sodium, pH > 7 | Needs reclamation |

Concept 4 of 5: Crop-growing conditions and plantation crops
Definition
- Tea — tropical/sub-tropical climate, heavy rainfall 150–250 cm, well-drained acidic soil (NOT lime-rich). Assam, Darjeeling, Nilgiris.
- Coffee — warm, moist climate with a dry spell at ripening, rolling well-drained fields; does NOT want sunshine above ~35 °C. Karnataka is the leading producer.
- Crop-product pairings the NDA tests: food crop = ragi, cash crop = jute, plantation crop = coconut (all correctly matched).
- Specialised farming: apiculture = honey, sericulture = silk, silviculture = forestry, viticulture = grapes.
| Crop / activity | Key condition or product |
|---|---|
| Tea | 150–250 cm rain; acidic, well-drained soil (NOT lime) NDA 2018 — only conditions 1 and 2 hold; 'soil should contain lime' is wrong. |
| Coffee | Warm + moist, dry spell at ripening; Karnataka leads NDA 2017 — correct set is 1, 2 and 4 (not the '>35 °C sunshine' clause). |
| Apiculture | Honey |
| Viticulture | Grapes |

Concept 5 of 5: Farming types, dry-land farming and farm schemes
Definition
- Features of Indian agriculture — subsistence farming, heavy population pressure on land, dependence on the monsoon. Predominance of cash crops is NOT a feature.
- Intensive subsistence agriculture — practised in India, Japan, Indonesia; NOT in Canada (extensive mechanised farming).
- Dry-land farming — confined to areas with rainfall less than 75 cm.
- An area leaves the drought-prone category if 20% or more of its gross cropped area is irrigated.
- RAD (Rainfed Area Development) — diversified farming, soil-health management, cluster-based approaches. 'Optimizing canal irrigation' is NOT an RAD strategy.
- NFSM-CC (Commercial Crops) covers cotton, jute and sugarcane — NOT coffee.
| Item | Key threshold / fact |
|---|---|
| Dry-land farming | Rainfall < 75 cm NDA 2020 — confined to areas below 75 cm rainfall. |
| Excluded from drought-prone | ≥ 20% gross cropped area irrigated NDA 2020 — 20 per cent or more under irrigation. |
| RAD scheme | NOT canal irrigation |
| NFSM-CC commercial crops | Cotton, jute, sugarcane (NOT coffee) |
