stress on both genotypes. We have made an attempt to
find out a range of N levels on both lines that were
either limiting or in excess, because both genotypes
have different degrees of salt tolerance (Siddiqui et al.
2009). One of the primary objectives was to determine
how these genotypes differing in salt tolerance responded
to NaCl and N combination with respect to
their photosynthetic capacity and accumulation of
osmoprotectants and nutrients as well as yield
performance.
