One of the crucial climate variables affecting agricultural plant responses is salinity (an abiotic stress). Since salt deposition affects wide areas, soil salinity has become a prevalent issue. The current field experiment was conducted to find out the effect of adding potassium (20, 40, and 60 Kg K2O.fed-1) to the soil alone or together with foliar application of gibberellic acid (50 and 100 ppm) after 30 and 60 days of sowing during the two growing seasons of 2021 and 2022 on growth, some physiological parameters, yield and the quality of canola seeds grown in saline soil. The addition of potassium alone or in the presence of foliar spray with GA3 improved all the tested parameters of canola plant (Photosynthetic pigments, relative water content, tissue water content and all yield parameters). Also, the macro- and micro-elements (N, P, K, Zn, Fe and Mn) and quality indicators (oil, carbohydrates, protein and total antioxidants) in the yielded seeds were increased. The most pronounced treatment was 40 kg K2O.fed-1 + 100 mg l-1 of GA3. The result of correlation analysis revealed that seed yield has a strong positive correlation (r=1) with seeds nutrition parameters content (Oil yield, protein, carbohydrate, N, P, K, Fe, Zn and Mn). In conclusion, the addition of potassium to the soil with GA3 spraying increased canola output and growth, as well as the nutritional content of its seeds.
