Consider the following pairs:

Region Well-known for the production of
1. Kinnaur Areca nut
2. Mewat Mango
3. Coromandel Soya bean

Which of the above pairs is/are correctly matched?

  1. A1 and 2 only
  2. B3 only
  3. C1, 2 and 3
  4. DNone
Show answer

Answer: (D) None

All three pairs are WRONG — a rare 'None' answer.

(1) Kinnaur (Himachal Pradesh) — famous for apples, dry fruits, and chilgoza pine nuts, NOT areca nut.

Areca nut grows in warm, tropical coastal regions like Karnataka, Kerala, and Assam.

(2) Mewat (Haryana/Rajasthan border) — an arid/semi-arid region, NOT known for mango.

Mango-famous regions include Malihabad (UP), Ratnagiri (Maharashtra), and Malda (West Bengal).

(3) Coromandel (eastern coast of Tamil Nadu/Andhra Pradesh) — known for rice cultivation, NOT soybean.

Soybean is grown predominantly in central India — Madhya Pradesh is called the 'Soya State.'

When all three pairs are obviously mismatched geographically, answer 'None.'

(Ref: Khullar, India Comprehensive Geography)

Why this was asked

This tests knowledge of specific regional agricultural specializations across India's diverse climatic zones.

All three pairs are deliberately wrong - Kinnaur produces apples not areca nut, Mewat is arid and unsuitable for mangoes, and Coromandel grows rice not soybeans.

UPSC is checking if students can match crops to their correct agro-climatic zones rather than getting confused by similar-sounding regions.

Kinnaur Region & Agricultural Products

Geography Kinnaur

Kinnaur Region: Location, Climate & Agricultural Products

Must know

Kinnaur is a district in Himachal Pradesh known for apples and dry fruits

Located in the trans-Himalayan region with cold, dry climate

NOT suitable for areca nut which needs warm tropical climate

Good to know

Famous for chilgoza pine nuts and barley cultivation

Geographic Context

Kinnaur is a high-altitude district in Himachal Pradesh bordering Tibet. Its trans-Himalayan location gives it a cold, dry climate unsuitable for tropical crops like areca nut.

Exam traps

Trap: Pairing Kinnaur with areca nut — wrong climate zone entirely

Remember: High altitude = apples, coastal tropics = areca nut

Chilgoza pine nuts are Kinnaur's unique specialty crop

Mewat Region & Agricultural Limitations

Geography Mewat

Mewat Region: Arid Climate & Agricultural Constraints

Must know

Mewat spans Haryana-Rajasthan border with arid/semi-arid climate

NOT suitable for mango cultivation due to water scarcity

Famous mango regions are Malihabad (UP), Ratnagiri (Maharashtra)

Good to know

Mainly grows bajra, mustard, gram — drought-resistant crops

Geographic Constraints

Mewat region straddles the Haryana-Rajasthan border and experiences arid to semi-arid climate with irregular rainfall. This makes it unsuitable for water-intensive crops like mango.

Exam traps

Trap: Assuming arid Mewat can grow water-loving mangoes

Remember: Mango needs 750mm+ rainfall, Mewat gets 300-500mm

Malihabad-UP is the classic mango region, not Mewat

Coromandel Coast & Rice Cultivation

Geography Coromandel

Coromandel Coast: Rice Cultivation Hub, Not Soybean

Must know

Coromandel Coast covers eastern Tamil Nadu & Andhra Pradesh

Famous for rice cultivation in deltaic plains, NOT soybean

Soybean is grown in central India — Madhya Pradesh is the 'Soya State'

Good to know

Coromandel has Cauvery & Krishna river deltas ideal for rice

Geographic Profile

The Coromandel Coast stretches along the eastern shores of Tamil Nadu and southern Andhra Pradesh. Its fertile deltaic plains formed by rivers like Cauvery and Krishna make it ideal for rice cultivation, not soybean.

Exam traps

Trap: Linking coastal Coromandel with continental crop soybean

Remember: Deltaic coast = rice, black soil plateau = soybean

Madhya Pradesh produces 60% of India's soybean, not coastal regions

Areca Nut Cultivation Zones

Geography Areca nut

Areca Nut: Tropical Coastal Cultivation Requirements

Must know

Areca nut (betel nut) needs warm, humid tropical climate

Major producers: Karnataka (70%), Kerala, Assam

Requires 1,500mm+ rainfall and coastal/high humidity areas

Cannot grow in cold, dry regions like Kinnaur

Climatic Requirements

Areca nut (also called betel nut) is a tropical palm requiring high temperature (25-35°C), heavy rainfall (1,500mm+), and high humidity. This limits cultivation to specific coastal and northeastern regions.

Major Mango Cultivation Regions

Geography Mango

India's Premier Mango Growing Regions & Varieties

Must know

Malihabad (UP) — famous for Dasheri and Safeda varieties

Ratnagiri (Maharashtra) — Alphonso mango capital

Malda (West Bengal) — Fazli and Langra varieties

Good to know

Mango needs 750mm+ rainfall and sub-tropical to tropical climate

Climatic Requirements

Mango cultivation requires sub-tropical to tropical climate with 750-1,250mm annual rainfall, well-drained soil, and warm temperatures (24-30°C). This explains why arid Mewat cannot support mango orchards.

Soybean Cultivation Regions

Geography Soya bean Coromandel

Soybean Cultivation: Central India's Black Soil Belt

Must know

Madhya Pradesh is called the 'Soya State' — produces 60% of India's soybean

Black cotton soil (regur) in central India ideal for soybean

NOT grown on coastal deltaic plains like Coromandel

Good to know

Other producers: Maharashtra, Rajasthan, Karnataka

Geographic Distribution

Soybean thrives in the black cotton soil belt of central India, particularly Madhya Pradesh which alone produces 60% of national output. The Coromandel coast's deltaic alluvium is unsuitable for soybean cultivation.
