Salinity tolerance in potato cultivars was studied in polythene bags of 30 cm size. A 50% yield reduction occurred at 4.81–5.70 dSm−1 depending on cultivar. It was estimated that if soil salinity exceeds 1.92 dSm−1, the mean potato yield declined by 14.78% per unit increase in soil salinity. Cultivar Kufri Sindhuri showed maximum tolerance to salinity followed by Kufri Badshah and Kufri Chandramukhi. The minimum yield decline was 13.91% with per unit increase in soil salinity in cultivar JH-222 as compared to other cultivars.
