The availability of fresh water for agricultural use is declining in many areas of world due to increasing water
needs of industries and municipalities. Thus agriculture faces challenges of using low quality waste water and
saline water for crop production. Many studies indicate that these water resources traditionally classified as
unsuitable for irrigation can be used successfully to grow crops without long-term hazardous consequences to
crops and soils if proper management strategies are established. These strategies include adopting advanced
irrigation technology, selection of salt tolerant crops, leaching of salts below the crop root zone.
Water scarcity is becoming one of the major limiting factor for sustainable agriculture in the semi arid regions
of the world. In India the entire arid and semi-arid regions have been characterised by low rainfall and has the
problem either of water scarcity or poor quality groundwater. The use of saline/alkali ground water posses a
major threat to plant growth and health, which is mostly observed in semiarid parts (Minhas and Bajwa, 2001).
In India, the regions identified for poor quality water are major parts of Rajasthan, Gujarat, Haryana, North
western UP and South western Punjab. Poor quality water constitutes 32-84 % of ground water surveyed in
different parts of India is either saline or alkali (Minhas, 1996).
Saline water upto 11 dS/m has been used successfully for commercial irrigation for a number of crops globally
(Rhodes et al., 1992). However, in order to assure maximum yield form crops irrigated with saline water, it is
necessary to develop special management techniques. Presently drip irrigation is widely regarded as the most
promising irrigation system to use saline water. Several factors contribute to the good results obtained with
saline water irrigation using drip irrigation under protected structures. (I) less water use results in less salt
deposited on the beds, (ii) avoidance of leaf burn, (iii) high frequency drip irrigation prevents the soil from
drying out between irrigations, thereby avoiding peaks in salt concentration and concomitant high osmotic
potentials and (iv) salts are continuously leached out from the wetted section and accumulate at the wetting
front away from the active root zone.
