salinity have a negative impact on plant growth. The present research work was conducted at Botanical Garden Department of Botany, University of Malakand, Khyber Pakhtunkhwa Pakistan. Different maize verities at morphological level are treated with different salt stress as compare to control environment. After germination we evaluated four maize for morphological study. different concentration (0, 50, 100 and 200) MNaCl were applied at appropriate stages. Salt stress show reduction in growth of all maize varieties. plant height incase control and with salt treated mean value was 31.27, with standard error 1.16, coefficient of variance was 26.94, range from Minimum 25cm and maximum 32cm, leaf length incase control and with salt treated mean value was 21.50, with standard error 1.74, coefficient of variance was 33.45, range from Minimum8.00cm and maximum 32.00cm, 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 Minimum0.30cm and maximum 0.50 respectively. All varieties were compared under different salt stresses to control condition.
