In order to study the response of various sorghum genotypes to different salinity levels, a pot experiment was carried out at NWFP Agricultural University Peshawar Pakistan during 1997. Analysis of the data revealed that significant differences were observed for shoot fresh weight, shoot dry weight, shoot Na+ and K+ concentration both at 15 and 30 days after salt application. Three sorghum genotypes PARC SV-8, PARC SV-1 and PARC SV-2 performed significantly better than the others. Increasing salinity levels had significantly reduced shoot fresh weight, shoot dry weight and shoot K+ concentration at 15 and 30 days after salt application. Similarly, interaction between various genotypes and salinity levels had significantly affected shoot fresh weight and shoot dry weight at 15 days and shoot Na+ and K+ concentration at both 15 and 30 days after salt application.
