Agro-Climatic Zones of Chhattisgarh
Chhattisgarh's three agro-climatic zones (Plains, Bastar Plateau, Northern Hills): districts, rainfall, soils, crops and IGKV research stations for CGPSC.
Prerequisites
- Rice Bowl of India: Cropping Pattern: the crops you will now place on the map
- Physiographic Divisions: the three agro-climatic zones copy the three relief units
- Climate and Soils of Chhattisgarh: rainfall pattern and local soil names
The Hook: Three Farmers, One State
A farmer near Arang in the plain transplants paddy in bunded Kanhar fields and hopes the Mahanadi canal will water a gram crop in winter. A farmer near Kondagaon in Bastar sows maize and kodo on a red, gravelly upland at the forest edge. A farmer near Ambikapur in the north grows paddy and niger, and worries about frost in January. All three live in Chhattisgarh, but they farm in three different worlds.
How does agricultural science divide the state, and why does the division matter for policy?
Why it matters: Prelims asks the number and names of the zones, the wettest zone and zone-wise crops. Mains GS-III asks for region-specific strategies: a single “paddy policy” does not fit all three zones.
What Is an Agro-Climatic Zone?
An agro-climatic zone (कृषि-जलवायु क्षेत्र) is a land unit with broadly uniform climate (especially rainfall and temperature), soils, terrain and cropping potential, so that one package of crops and practices suits it.
| Level | Scheme | Chhattisgarh’s place |
|---|---|---|
| National | Planning Commission’s 15 agro-climatic regions (1988–89) | Chhattisgarh lies in Region VII: Eastern Plateau and Hills |
| State | National Agricultural Research Project (NARP) zones, used by IGKV Raipur | 3 zones: Chhattisgarh Plains, Bastar Plateau, Northern Hills |
The research and extension body for these zones is Indira Gandhi Krishi Vishwavidyalaya (इंदिरा गांधी कृषि विश्वविद्यालय), Raipur, the state agricultural university (established 1987), with a zonal research station in each zone.

Zone-Wise Issues and Strategies (Mains material)
| Zone | Key problems | Strategy |
|---|---|---|
| Plains | Paddy mono-cropping; dry western plain (Maikal rain shadow: Kabirdham, Bemetara); under-used rabi; soil fatigue | Diversify rabi to gram, lathyrus, linseed through utera; efficient canal use; soybean–gram rotations; protective irrigation for the western plain |
| Bastar Plateau | Poor, eroded upland soils; almost no irrigation; low input use; remoteness and insecurity in Left-Wing Extremism-affected districts | Millets (kodo-kutki, ragi) with processing and MSP; maize; watershed works and small tanks; forest-produce value chains; organic branding |
| Northern Hills | Short growing season, frost and cold; hilly terrain; low irrigation | Maize, niger, mustard and pulses; horticulture on slopes; soil and water conservation; solar pumps |

Level 3: Mains Answer Writing
Q1. Name the agro-climatic zones of Chhattisgarh and state one distinguishing feature of each. (60 words)
- Chhattisgarh Plains: central basin; lowest rainfall but the most irrigation; Kanhar–Dorsa–Matasi–Bhata soils; paddy with rabi gram and lathyrus.
- Bastar Plateau: highest rainfall; red and laterite uplands; maize, kodo-kutki, ragi, niger; about 97% rain-fed.
- Northern Hills: Surguja division; red-yellow soils, cold winters; paddy, maize, niger, mustard.
Q2. “One agricultural policy cannot suit all of Chhattisgarh.” Examine this statement with reference to the state’s agro-climatic zones. (150–200 words)
Intro: IGKV divides Chhattisgarh into three agro-climatic zones that differ in rainfall, soil, terrain and irrigation.
Differences:
- Plains: driest zone yet the most irrigated; deep Kanhar soils; paddy surplus and procurement-driven farming.
- Bastar Plateau: wettest, but thin red-laterite uplands and about 97% rain-fed; millets and forest produce matter more than surplus paddy.
- Northern Hills: cold winters, slopes and about 95% rain-fed; maize, niger and pulses.
Why uniform policy fails: a high paddy price mainly rewards plains farmers with surplus; uplands need water harvesting, millet markets and soil conservation instead.
Zone-specific approach:
- Plains: rabi diversification via utera, water-use efficiency, soybean–gram rotations.
- Bastar: Millet Mission, processing units, watershed works, organic and tribal branding.
- North: maize and pulses, horticulture, solar pumps.
Conclusion: Region-specific packages, guided by IGKV’s zonal stations, give more equitable and climate-resilient growth.

Key Takeaways
- Chhattisgarh has three agro-climatic zones matching its three relief units: Plains, Bastar Plateau, Northern Hills.
- Bastar is the wettest, the Plains the driest, yet the Plains are the most irrigated and grow the most paddy.
- Nationally the state lies in the Eastern Plateau and Hills Region (VII).
- Almost all farming outside the canal commands is rain-fed.
- Policy should be zone-specific: rabi diversification in the plain, millets in Bastar, maize and pulses in the north.
What’s Next
- Irrigation Projects of Chhattisgarh: the canal commands that make the plain different
- Agricultural Schemes in Chhattisgarh: Millet Mission and diversification incentives
- Tribes of Chhattisgarh: the farming communities of Bastar and the northern hills
