Abstract
Irrigation is an ageold practice, but efficient
irrigation is still a topic of study. The irrigation effici
encies if improved, we save the losses of water which in turn
will command additional area. Advances in irrigation techno
logy provide means to control over water delivery rates to
achieve a reasonable balance of upstream losses, deep
percolation and downstream tail water losses and greater
application uniformity over the fields.
The surface irrigation methods viz. furrow, border
and basin are generally favoured by the farmers though there
are certain added advantages if sprinkler and trickle
irrigation systems are used under particular set of conditions.
As thevuses for water supplies become more competitive, the
need increases for utilising the available water more
judiciously and save water whereever possible. The one way
of saving the water is to improve the overall efficiency of
prevailing irrigation systems. The another way is to use
less water per unit of production. One of the ways to improve
the efficiency is to estimate the losses and take necessary
measures to minimise them. The losses in the irrigation system
can broadly be classified as transit losses, management losses
and nonbeneficial use of applied water.
