**IRRIGATION TECHNICS
Irrigation:-The science of artificial application of water to the land,in accordance with the 'Crop requirements' throughout the 'Crop period' for full-fledged nourisement of the crop is defined as a irrigation.
NECESSITY OF IRRIGATION IN INDIA:-
India is a tropical country with a vast diversity of climate,topography and vegetation.Rainfall in india,varies considerably in its place of occuaranc,as well as in its amount.Crops cannot,therefor,be,raised successfully,over the entire load,without providing artificial irrigation on fields.
More than seventy percent of our population directly depends on agricultur.Out of a total geographical area about 328 million hectares,about 184 million hectares is the cultivable area.
ADVANTAGES OF IRRIGATION:-
Irrigation project is designed,keeping in view of its economics benefits........likely to be occured or likely to be incurred.there is a big investment on the project and the future recuring changes for maintenence and operation.The project estimate is generally sanctioned when the benefit gives at least about 8% interest on the capital outlay.
The importance and advantages of irrigation during the times of acute food shortages and growing population of our country......
some of the advantages of irrigation......
(I)Increase in foode production.........(Irrigation helps in increasing crop yeilds,And hence,to attain self-sufficiency in food).
(II)Optimum quantity..............(Yeild will be smaller for any quantity lesser than or in excess of this optimum quantity).
(III)Elemination of mixed cropping ...............(in the areas where irrigation is not assured,generally mixed cropping is adopted)....By mixed cropping,showing together of two or more crops in the same field.....If the weather condition are not favourable to one of the crops,they may be better suitable for the other,and thus the farmer may get at least some yeild.
(IV)General properity........Revenue returns with well developed irrigation helps in prosperity of the entire nation and community.
(V)Domestic water supply......helps in augmenting the water supply in near by villages and towns,where the sources of water are not available....its also helps in providing drinking water for animales,and water for swimming bathing etc.
(VI)Facilities of communication........(Irrigation channels are generally provided with embankments and inspection roads......these inspection paths provide goodroadways)
(VII)Inland nevigation ..........Larger irrigation canels can be used and developed for nevigation purposes
(VIII)Generation of hydro-electric power.........Cheaper power generation can be obtained from water development projects,primarily designed for irrigation alone........for example Ganga and sarda canels,constructed for irrigation,are new generating hydro-electric power as a side product up to about 80,000 kilo watts.
