Agriculture
- Cropping seasons:
| Season | Sown / harvested | Crops |
|---|---|---|
| Kharif | Sown June–July (monsoon), harvested September–October | Rice, maize, jowar, bajra, cotton, groundnut, soybean, jute, arhar |
| Rabi | Sown October–December, harvested March–April | Wheat, barley, gram, mustard, peas, masoor |
| Zaid | March–June | Watermelon, cucumber, moong, fodder |
- Major crops and leading states (recent years):
- Rice: West Bengal, UP, Punjab. Bihar is a significant producer.
- Wheat: UP, MP, Punjab.

- Jute: West Bengal, Bihar, Assam.
- Tea: Assam, West Bengal.
- Coffee: Karnataka.
- Rubber: Kerala.
- India's global rank:
- 1st in milk, pulses and jute;
- 2nd in rice, wheat, sugarcane, fruits and vegetables;
- India became the largest rice exporter.
- Irrigation:
- About 55% of net sown area is irrigated.
- Main sources: tube wells and wells (more than 60%), canals, tanks.
- Schemes: PMKSY ("Har Khet Ko Pani", "Per Drop More Crop").
- Revolutions:
- Green (food grains);
- White (milk): Operation Flood, Verghese Kurien;
- Blue (fish);
- Yellow (oilseeds);
- Golden (horticulture);
- Pink (meat and prawns);
- Sweet (honey).
Minerals
| Mineral | Main areas | Notes |
|---|---|---|
| Iron ore | Odisha (Keonjhar, Sundargarh), Jharkhand (Noamundi, West Singhbhum), Chhattisgarh (Bailadila), Karnataka (Bellary) | Odisha is the top producer; hematite and magnetite |
| Coal | Jharkhand (Jharia, Bokaro, Karanpura, Rajmahal), Odisha (Talcher), Chhattisgarh (Korba), West Bengal (Raniganj) | Mostly Gondwana coal; Jharkhand and Odisha have the largest reserves, about a quarter each |
| Manganese | Odisha, MP, Maharashtra, Karnataka | |
| Bauxite | Odisha (Panchpatmali), Jharkhand (Lohardaga), Chhattisgarh, Gujarat | Aluminium ore |
| Copper | Jharkhand (Singhbhum, Ghatshila), Rajasthan (Khetri), MP (Malanjkhand) | |
| Mica | Jharkhand (Koderma, Giridih), Andhra (Nellore), Rajasthan | |
| Uranium | Jaduguda (Jharkhand), Tummalapalle (Andhra) | UCIL |
| Gold | Karnataka (Kolar, Hutti) | |
| Petroleum | Mumbai High, Gujarat, Assam (Digboi, 1889, the oldest refinery), Rajasthan (Barmer) | |
| Limestone | MP, Rajasthan, AP, Bihar (Rohtas) | For cement |
The Chotanagpur plateau is India's mineral storehouse (the "Ruhr of India").
Energy
- Installed capacity: roughly 480–500 GW in 2025. Coal-based power is still the largest share.
- Non-fossil capacity: passed 50% of installed capacity in 2025, well ahead of the 2030 target in India's NDC.
- Targets: 500 GW of non-fossil capacity by 2030 and net zero by 2070.
- Solar: Rajasthan (Bhadla) and Gujarat lead. Wind: Gujarat and Tamil Nadu.
- Nuclear power plants: Tarapur (1969, the first), Rawatbhata, Kudankulam, Kaiga, Narora, Kakrapar, Kalpakkam.
- Hydropower: Bhakra–Nangal, Tehri, Sardar Sarovar, Nagarjunasagar.
- The DVC (1948) was modelled on the Tennessee Valley Authority. Its dams are Tilaiya, Konar, Maithon and Panchet.
Industry: location factors
- Industries locate near raw materials, power, labour, markets, transport, capital and government policy.
- Weight-losing raw materials (iron ore, coal, sugarcane) pull an industry towards the raw material.
| Industry | Location logic | Examples |
|---|---|---|
| Iron and steel | Near iron ore and coal | TISCO, Jamshedpur (1907); SAIL plants at Bokaro (USSR help), Bhilai (USSR), Rourkela (Germany), Durgapur (UK); Vizag; Salem |
| Cotton textiles | Raw cotton, humid climate, ports, markets | Mumbai, Ahmedabad ("Manchester of India"), Coimbatore |
| Jute | Raw jute, water, cheap labour, port | Hooghly belt |
| Sugar | Sugarcane is weight-losing and perishable | UP, Maharashtra; north Bihar (old mills) |
| Cement | Limestone | MP, Rajasthan; Bihar (Rohtas, Banjari) |
| Petrochemicals | Refineries, ports | Jamnagar (world's largest refinery complex), Barauni (Bihar, 1964) |
| IT and services | Skilled labour, infrastructure | Bengaluru, Hyderabad, Pune |
Transport and communication
- Roads:
- India has about 63 lakh km of roads, the 2nd largest network in the world.
- NHDP (1999): the Golden Quadrilateral and the NS–EW corridors.
- Bharatmala; PMGSY (rural roads, 2000).
- NH 44 is the longest national highway (Srinagar–Kanyakumari).
- Railways:
- The first train ran Bombay–Thane, 16 April 1853.
- It is run through zonal railways. East Central Railway has its headquarters at Hajipur (Bihar).
