Agriculture takes place in the river valleys of Uttarakhand (a meagre 10-15% of the total land area). Over time, several slopes have been shaped into field terraces, a common trend in mountain agriculture everywhere. The Uttarakhand farmers have also developed advanced manure, crop rotation, and inter-cropping practices. Most land along the slopes remains unirrigated. Three types of agriculture are traced to these river valleys adapting to the type of land:
Hoe cultivation, rotation of 3 crops in 5 years
Important crops: millets, amaranth
Always terraced, but unirrigated
Important crops: mandua, jhangora, chaulai
paddy cultivation, low-lying, irrigated, double cropped
Important crops: wheat, rice, sugarcane, etc.
| Ecological sub-region | Altitude(m) | Chief Crops |
| Lower Dun, Terai | 300-600 | wheat, rice, sugarcane |
| Upper Dun, Bhabar, lower Shivaliks | 600-1,200 | wheat, rice, mandua, jhangora, chaulai, maize |
| Middle Garhwal-Kumaon | 1,200-1,800 | wheat,rice,mandua,jhangora,"cheena",potato, barley |
| Upper Garhwal-Kumaon | 1,800-2,400 | wheat, barley, potato, chaulai, cheena, "phaphra" |
| Cold Zone | 2,400-3,600 | wheat,barley,potato,phaphra,chaulai,"kauni","ogal" |
Different pulses are inter-cropped during the two harvest periods -
- early winter after the rainy season (millet)
- midsummer before the hot dry season (barley-wheat)
Agriculture comprises an important factor contributing to the economy of Uttarakhand.
