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.

3. CANAL IRRIGATION Canal irrigation construction service Irrigation canal with water on the plantation field

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

6. 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.

7. 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.

9. 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
