ABSTRACT
The global threat posed by rising soil salinity to agricultural production is serious. The Harmonized World Soil Database is the only database that currently offers data on worldwide soil salinity; however, it has a number of limitations regarding the way soil salinity is measured. A new assessment is therefore required. The present research work was conducted at Botanical Garden, Department of Botany, University of Malakand, Khyber Pakhtunkhwa Pakistan. Different mays verities at morphological level were treated with different salt stress as compared to control environment. After germination, four maize genotypes were evaluated for morphological study. Different concentration (0, 50, 100 and 200) mM NaCl were applied at appropriate stages. Salt stress shows reduction in growth of all mays varieties. Plant height in case of control and treated, the mean value was 31.27, standard error 1.16, coefficient of variance was 26.94, range from Minimum 25 cm and maximum 32 cm, leaf length in control and treated, the mean value was 21.50, standard error 1.74, coefficient of variance was 33.45, range from Minimum8.00cm and maximum 32 cm, leaf width incase control and with salt treated mean value was 0.37, with standard error 0.02, coefficient of variance was 0.00, range from minimum 0.30cm and maximum 0.50, respectively. All varieties were compared under different salt stresses to control condition.
