cultivated land and nearly half of irrigated land is saltaffected,
greatly reducing yield well below the genetic
potential (Ghassemi et al. 1995; Munns and
James 2003; Flowers 2004). Soil salinization is becoming
a more acute problem for sustainable development
of agricultural production, primarily because
of declining irrigation systems and type of irrigated
water (Ghassemi et al. 1995).
Saline environment is generally deficient in nitrogen
(Amonkar and Karmarkar 1995) and reduction
in NO3
- uptake could be mostly due to high Cl- content
