Abstract: Two field experiments were conducted during the season of 2013/2014 and 2014/1015 at Sabaheya Soil, Water and Environment Research Institute, Agricultural Research Station to investigate the role of proline foliar application (0 ,150 and 300 ppm) in counteracting the harmful effect of salinity stress at various concentartions (500,1000,2000 and 3000ppm) on potato plants growth characters, yield and its components. The results showed that all growth characters including: plant length, number of shoot, total yield of tuber/plant (gm), number of tubers/plant and average tuber weight/plant were decreased with increasing salinity stress level alone or combined with applied proline . On the other hand, salinity stress levels alone or combine with applied proline foliar application increased tuber dry matter%, starch content, total sugars and reducing sugars. It could be noticed that applied proline could partially reduced the harmful effect of salinity stress on growth and yield characters of potatoes.
