Irrigation & Water Management

This section usually covers surface, sub-surface, sprinkler, and drip irrigation, crop water requirement, duty, delta, base period, irrigation scheduling, soil-moisture concepts, water-use efficiency, and watershed management.

Yes. It is one of the key practical areas in Unit 3 because it connects crop production with efficient use of water, method selection, scheduling, and conservation.

Drip irrigation applies water close to the root zone in small amounts, while sprinkler irrigation sprays water over the field like artificial rainfall. CUET questions often compare them on water efficiency, crop suitability, and field conditions.

These are core irrigation terms used to express water requirement relationships. Students are expected to understand what each term means and how they are related when discussing crop water use and irrigation planning.

Irrigation scheduling is important because it helps decide when and how much water to apply based on crop need, soil moisture, and climate. It supports better water use and avoids over- or under-irrigation.

Yes. Watershed management is included because irrigation is not only about applying water to a field; it also involves conserving and managing land and water resources over a drainage area.

Students usually remember drip irrigation as one of the most water-efficient methods because it minimizes wastage and delivers water directly to the crop root zone.

A strong order is irrigation-method classification first, then water-use efficiency, then duty, delta, and base period, and finally irrigation scheduling and watershed management.

Most students revise this topic fastest with comparison tables for irrigation methods, short definitions for duty-delta-base period, and one-line notes on scheduling and watershed concepts.
