Chapter 5: Bihar: Agriculture and Forest Resources — notes
The chapter’s 8 parts in the book’s order — the first idea of each and the points Medha Ma’am writes on the board — and the summary at the end. The full lesson and a check question for each part are in the app.
1. Bihar: An Agricultural State and Its Crop Seasons
You should know that Bihar is called an agricultural state because 80 percent of its population depends on agriculture for their living.
- • Bhadai (Autumn): May-June to Aug-Sept
- • Agahni (Winter/Kharif): mid June-Aug to Nov-Dec
- • Rabbi (Spring): mid Oct-Nov to April
- • Garma (Summer): needs irrigation/wet low land
- • 80% population depends on agriculture
2. Food Crops of Bihar
Okay, so let's learn about the important food crops of Bihar — Paddy, Wheat, Maize, coarse crops, oilseeds and pulses.
- • Paddy: 33.54 lakh ha -> 50 lakh tonnes (2006-07)
- • Wheat: 20.5 lakh ha -> 43 lakh tonnes
- • Maize: 798.31 thousand metric tonnes
- • Oilseeds: 140.60 thousand ha -> 149 thousand m.t.
- • Pulses: Rabbi 372 + Kharif 74 thousand m.t.
3. Commercial Crops, Vegetables and Fruits
Okay, so besides food crops, Bihar also grows some important commercial crops.
- • Sugarcane: 117 th. ha -> 5338 th. m.t. (W. Champaran 1st)

- • Problems: soil erosion, inferior seeds, small fields
- • Orthodox views, irrigation only 46% land
- • Floods: 64 lakh hectares flood prone
- • Also: scarcity of capital, poor animals, social problems
5. Water Resources and Means of Irrigation
Okay, so let's talk about water in Bihar.
- • Surface water: rivers, reservoirs, ponds
- • Underground water: wells, tube wells, hand pumps
- • 95%+ water used for irrigation
- • Canal: 40.63% irrigated land (most important)
- • Tube well: 38.77%; Wells: 2%; Tanks: 2.10%
6. Canals and River Valley Projects
Let us now learn about the canals built before and after independence.
- • Son Canal (1874): first modern irrigation project
- • Son Project -> 'Rice Bowl of Bihar'
- • Gandak Canal: barrage near Valmiki Nagar, 743 m
- • Kosi Project: started 1955, barrage at Hanuman Nagar
- • Kosi barrage completed 1963
7. Forest Resources of Bihar
Now let's talk about forests.
- • Per capita forest: Bihar 0.05 ha vs National 0.53 ha
- • Moist Deciduous: southern hills, NW; Sal, Shisham
- • Dry Deciduous: Kaimur, Rohtas; Khair, Palash, Neem
- • Plains & Diara: no natural forests
- • Hilly areas (W. Champaran, Kaimur, Banka, Jamui, Gaya, Munger): more forest
8. Forest and Wild Life Conservation
Okay, so let's talk about forests and wildlife in Bihar.
- • Forest cover in Bihar: 6.87% (National policy wants 33%)
- • Rehabilitated forest: 2849 ha (2004-05) -> 15237 ha (2006-07)
- • 2005-07: more than 2 crore plants planted
- • 14 sanctuaries + 1 National Park = 2064.41 hectares
- • Sanjay Gandhi Botanical Garden, Kanwar lake, Kusheshwar Asthan
Summary
Okay, so let's go back over what we covered in this chapter. We started with Bihar as mainly an agricultural state. It has four crop seasons — Bhadai, Agahni, Rabbi and Garma. We saw the important food crops too, like paddy, wheat and maize. And we saw the commercial crops — sugarcane, jute and tobacco — along with vegetables and fruits like potato, mango and litchi. Then we looked at the problems farmers face. Soil erosion, inferior seeds, small fields, orthodox views, poor irrigation, and devastating floods — all of these hold agriculture back. After that, we moved to water resources and irrigation. Canals are the most important means, right? Then come tube wells, wells and tanks. And we also spoke about the big river valley projects — Son, Gandak and Kosi. These help with irrigation, and they generate hydro-electricity too. Finally, we looked at Bihar's forests. They're divided into Moist Deciduous and Dry Deciduous types, and they're spread unevenly across the state. We also saw the efforts made to conserve forests and wildlife — rehabilitation, plantation, and sanctuaries like Kanwar lake and Kusheshwar Asthan. Now, tell me — out of all these topics, which one did you find most interesting?
