2. INTRODUCTION
 Irrigation is the artificial application of water to
the land or soil.
 The process of artificial application of water to
the soil for the growth of agricultural crops is
termed as irrigation.
 It includes the construction of weirs, dams,
barrages and canal systems for the regular
supply of water to the culturable (i.e. cultivable)
lands.

4. CANAL IRRIGATION
 Canal irrigation- extensive plains
 Drained by well distributed perennial rivers
northern plains, coastal plains, deltas and broad
valleys of the peniunsula .
 Inundation canals -taken out without
constructing dams or 'bunds‘. Get water-stream
is flooded Have limited validity.
 The post-independence multi-purpose projects.

5. SOURCES OF IRRIGATION
 Depending upon the availability
 Water surface
 Ground water
 Rainfall conditions
 Rivers
 Well
 Tubewell
 Tap water

7. BENEFITS OF IRRIGATION
Following are the important benefits of irrigation;
 Yield of Crops: - In the period of low rainfall or
drought, the yield of crop may be increased by the
irrigation system.
 Improvement of Cash Crops: - Irrigation helps to
improve the cultivation of cash crops like vegetables,
fruits, tobacco, etc.
 Prosperity of Farmers: - When the supply of irrigation
water is assured, the framers can grow two or more
crops in a year on the same land. Thus the farmers may
earn more money and improve their living standard.

8. NECESSITY OF IRRIGATION
 Insufficient Rainfall: - When the seasonal rainfall is
less than the minimum requirement for the
satisfactory growth of crops, the irrigation system is
essential.
 Uneven Distribution of Rainfall: - When the rainfall
is not evenly distributed during the crop period or
throughout the culturable area, the irrigation is
extremely necessary
 Development of Agriculture in Desert Area: - In
desert area where the rainfall is very scanty, irrigation
is required for the development of agriculture.

10. DAMS
 Dam is a solid barrier constructed at a suitable
location across a river valley to store flowing water.
Storage of water is utilized for following
objectives :-
 Hydropower
 Irrigation
 Water for domestic consumption
 Flood control
 For navigational facilities
 Other additional utilization is to develop fisheries
