Irrigation Systems in Agriculture - Detailed Revision Notes
Irrigation systems form the backbone of Indian and Uttar Pradesh agriculture, compensating for erratic monsoon patterns. For the Allahabad High Court RO/ARO and UPPSC examinations, questions frequently target sources of irrigation (tube wells, canals), irrigation potential, efficiency of modern methods (drip/sprinkler), and UP-specific canal networks like the Upper Ganga Canal and Sharda Canal.
Major Sources of Irrigation in Uttar Pradesh
Uttar Pradesh relies heavily on groundwater and canal networks due to its vast fertile plains and perennial rivers. Tube Wells and Groundwater (नलकूप और भूजल): Tube wells constitute the largest source of irrigation in Uttar Pradesh, accounting for nearly 74-75% of the total net irrigated area. Weste...
Prominent Canal Systems of Uttar Pradesh
The Gangetic river system feeds multiple monumental canals that irrigate vast agricultural tracts across UP. Upper Ganga Canal (ऊपरी गंगा नहर): Take-off point is Bhimgoda Barrage near Haridwar (Uttarakhand). Opened in 1854, it irrigates Saharanpur, Muzaffarnagar, Meerut, Bulandshahr, Aligarh, and Ma...
Modern Irrigation Techniques & Efficiency
Shifting from flood irrigation to micro-irrigation is vital for sustainable groundwater management in water-stressed zones. Drip Irrigation (ड्रिप सिंचाई): Delivers water drop-by-drop directly to the plant roots via a network of valves, pipes, and emitters. It achieves water use efficiency of up to ...
Water Conservation & Institutional Framework
Governance, water policy, and legal frameworks governing surface and groundwater use in Uttar Pradesh. Groundwater Extraction Regulation: The UP Ground Water Management and Regulation Act provides norms for sinking new tube wells, mandating registration in over-exploited and critical blocks to preve...
Key Questions & Answers
- Which is the largest source of irrigation in Uttar Pradesh?
- Tube Wells / Groundwater (accounting for approx 74-75% of net irrigated area).
- When was the Upper Ganga Canal opened for irrigation?
- In 1854, taking off from Bhimgoda Barrage near Haridwar.
- What is the primary motto of the Pradhan Mantri Krishi Sinchayee Yojana (PMKSY)?
- 'Har Khet Ko Pani' and 'More Crop Per Drop'.
- Which canal system is the largest in Uttar Pradesh?
- The Sharda Canal System (originating from Banbassa).
Common Exam Traps
- Tube Wells vs Canals Share: Aspirants often confuse canals as the top irrigation source in UP due to their historical prominence. However, tube wells rank first (~75%), while canals rank second (~19%).
- Upper Ganga Canal Origin: Do not confuse Upper Ganga Canal origin (Bhimgoda Barrage, Haridwar) with Lower Ganga Canal origin (Narora, Bulandshahr).
