2. Definition
Pranamesh Chakraborty
Irrigation may be defined as the process of supplying water by
artificial means to agricultural fields for crop production. If water
available to the plants from rainfall is not sufficient, it is
supplemented by irrigation water.
In order to achieve this objective, an irrigation system is required
to be developed that involves planning, design, construction,
operation and maintenance of various irrigation works:
• Source: River, Reservoirs
• Control structure: Barrages, Head Regulators
• Distribution system: Irrigation Canals
Introduction

3. Types of Irrigation

Surface Irrigation
Sprinkler Irrigation
Drip Irrigation

4. Definition
Surface irrigation is defined as the group of
application techniques where water is applied
and distributed over the soil surface by gravity.
It is by far the most common form
of irrigation throughout the world

Sprinkler irrigation is a method of applying irrigation water
which is similar to natural rainfall.
Water is distributed through a system of pipes usually by
pumping. It is then sprayed into the air through sprinklers
so that it breaks up into small water drops which fall to the
ground.

Drip irrigation is sometimes called trickle irrigation and
involves dripping water onto the soil at very low rates (2-20
litres/hour) from a system of small diameter plastic pipes fitted
with outlets called emitters or drippers.
Water is applied close to plants so that only part of the soil in
which the roots grow is wetted, unlike surface and sprinkler
irrigation, which involves wetting the whole soil profile.
Suitable for high value row crops.
