This investigation was carried out on the effect of salinity on protein content in leaves and grains of four genotypes of oat (JHO-822, JHO-851, Kent and UPO-94). The plants were irrigated with different saline waters (3, 6, 7.2, 10, 12 and 14 dSm<sup>-1</sup>) in the field. Protein in leaf was analyzed at 90 days after sowing. Cv. JHO-822 and JHO-851 contained higher leaf protein at 3 and 6 dSm-1 but lower at 7.2 to 14 dSm<sup>-1</sup>. Kent and UPO-94 registered an increase in leaf protein only at 3 dSm<sup>-1</sup> but declined at all salinities. Grain protein of cultivars of oat also registered significant enhancement at 3 dSm-1 but significant reductions at other salinities. The higher protein content in leaves and grains in cv. JHO-822 may be due to higher photosynthetic rate of plants due to higher total leaf area.</span></p> ER -
