hi maam/sir the QUESTION is how can the efficiency of irrigation be increased?

answered-by-expert Expert Answer

Irrigation efficiency can be increased if we reduce the water losses during irrigation and acieve niformity of application. If either the water losses are large, or application uniformity is poor, efficiency will be low.

Proper irrigation scheduling is important if high efficiencies are to be achieved.

Aside from over-watering, the major losses associated with surface irrigation systems are direct evaporation from the wet soil surface, runoff losses, and seepage losses from water distribution ditches. If thesed can be reduced, irrigation efficiency can be increased.

In addition, irrigation should be done according to the nature of the crop as well as the nature of the soil in the fiels.
A cheap irrigation system suitable to an area should be adopted for obtaining maximum returns.
