Abstract: Salinity stress adversely affected the rice growth, productivity and yield from last few decades. Here, in this study the ameliorative role of foliar application of potassium (K) and salicylic acid (SA) have been investigated against salinity stress in rice. Four rice varieties (Kashmir Basmati, Basmati-370, Super-Basmati and Basmati-515) were exposed to NaCl stress (0, 100mM) and sprayed with SA (0.02%), K (0.1%) and their combination (SA+K) at vegetative and flowering stages. Salinity stress caused reduction in plant fresh and dry weight, plant height, chlorophyll and carotenoids contents, and photosynthetic rate.
