Meaning

Tea is a plantation beverage crop. It is a bush whose tender leaves are picked by hand and processed into tea. It grows best on well-drained hill slopes in warm, moist, frost-free tropical and subtropical areas. India is the world's second-largest producer of tea [2]. The crop is a classic UPSC example of how climate, slope and soil decide where a crop grows. The story of tea in India began with British-era estates in Assam.

Explanation

What kind of crop it is

  • Tea is a plantation crop.
  • Plantation agriculture means one crop grown on a large estate. It is grown for sale and often for export.
  • It needs a lot of labour and a lot of money.

  • It is closely linked to factories that process the crop.

  • Origin: tea is native to the hills of northern China. The British brought it to India.

  • The Tea Board (1953) is the body that develops and regulates the crop.

Conditions it needs

  • Climate: tropical or subtropical. It must be warm, moist and frost-free all year.
  • Rain: frequent showers spread evenly through the year.
  • Steady moisture keeps the bushes putting out soft new leaves.

  • These tender leaves are the part that is picked.

  • Soil: deep, fertile and well-drained, and rich in humus (dark organic matter from rotted plants).

  • Slope: hill slopes are best.
  • Rainwater runs off a slope quickly.
  • So water does not stand at the roots, and the roots do not rot.

Labour and processing

  • Plucking needs many workers. Most of them are women, who pick the leaves by hand.
  • Processing happens inside the tea garden.
  • Fresh leaves spoil quickly.
  • So each estate has its own factory close to the bushes.
  • This is why tea is a plantation crop linked to industry, not just a farm crop.

How tea spread in India

  • 1840s: the first plantations began in the Brahmaputra valley of Assam.
  • Next: the sub-Himalayan districts of West Bengal, namely Darjeeling, Jalpaiguri and Cooch Behar (the Duars–Terai belt).
  • Then: the Nilgiri and Cardamom hills of the Western Ghats, in Tamil Nadu and Kerala.

Where it occurs

  • India, main states (highest to lowest):
  • Assam has about 53% of the tea area and gives over half the output. The main area is the Brahmaputra valley.
  • West Bengal: Darjeeling, Jalpaiguri and Cooch Behar, in the Duars–Terai belt at the foot of the Himalaya.
  • Tamil Nadu: the Nilgiri hills of the Western Ghats.

  • Kerala (Cardamom hills) and Karnataka also grow tea [2].

  • India, minor areas: Kangra (Himachal Pradesh), Uttarakhand, Meghalaya, Andhra Pradesh and Tripura.

  • India's output: 1.203 million tonnes in April–December 2024-25 [2].
  • World:
  • NCERT says India grew about 21% of world tea (2018) and ranked second after China.
  • India is still the second-largest producer [2].
  • Kenya and Sri Lanka lead world tea exports. India's share of world exports has fallen.
  • India's tea exports were US$ 605.90 million in April–October 2025-26. This was 15.16% more than in the same months a year earlier [2].

Don't confuse with

  • Coffee: coffee is also a plantation beverage crop, but it is a crop of the Western Ghats highlands and grows under shade trees. Karnataka leads in coffee. Assam leads in tea. Coffee came from Yemen, and tea is native to northern China.
  • Rubber: rubber is an equatorial industrial crop. It needs over 200 cm of rain and over 25°C, and Kerala leads. Tea is a beverage crop, and its key need is evenly spread showers with no frost.
  • Commodity Board years: the Tea Board (1953) is the youngest of the three. The order is Coffee Board (1942) → Rubber Board (1947) → Tea Board (1953).
  • Darjeeling vs Nilgiris: Darjeeling is in the sub-Himalayan part of West Bengal. The Nilgiris are in the Western Ghats of Tamil Nadu. Both grow tea, but they are in different mountain systems.

Prelims Hooks

  • First tea plantations: 1840s, in the Brahmaputra valley of Assam. Tea is native to the hills of northern China.
  • Tea states, highest to lowest: Assam (about 53% of the area) > West Bengal > Tamil Nadu.
  • India's first GI tag: Darjeeling tea (2004-05). A Geographical Indication (GI) is a legal tag for a product whose quality comes from the place where it is made.
  • Place–state pairs: Darjeeling, Jalpaiguri, Cooch Behar → West Bengal. Nilgiri hills → Tamil Nadu. Cardamom hills → Kerala. Kangra → Himachal Pradesh.
  • World rank: India is the second-largest producer, after China [2], but Kenya and Sri Lanka lead tea exports. A common trap is to treat "largest producer" and "largest exporter" as the same thing.
  • Condition trap: tea needs frost-free weather and evenly spread showers all year, plus well-drained slopes. Waterlogged flat land is unsuitable.

Mains Points

  • Why tea grows where it does (GS-I)
  • Tea needs frost-free warmth, frequent showers and well-drained, humus-rich slopes.
  • These are found in the Brahmaputra valley, the sub-Himalayan foothills of Bengal and the Western Ghats (Nilgiri and Cardamom hills).

  • British-era plantations started in Assam in the 1840s. They left behind an estate system that uses a lot of labour, mostly women pluckers, with a factory on each estate.

  • Trade and value addition (GS-III)

  • India is the second-largest producer [2], but its share of world exports has fallen to Kenya and Sri Lanka.
  • Exports are recovering. They rose 15.16% to US$ 605.90 million in April–October 2025-26 [2].
  • Possible answers:
    • GI-based branding, building on Darjeeling tea, India's first GI.
    • Support for small growers.
    • Replanting old gardens to raise yields.
