Soil and foliar application of potassium enhances fruit yield and quality of tomato under salinity

Potassium plays a key role in the survival of plants under saline conditions in mitigating the adverse effects of sodium. The effect of application of potassium to soil (0, 3.3, and 6.6 mmol/kg) and leaves (4.5 and 9 mM) on tomato yield and quality under 3 salinity treatments (0, 7.5, and 15 dS m–1), using 2 salt-tolerant (Indent-1 and Nagina) and 2 salt-sensitive (Peto-86 and Red Ball) genotypes, was studied in a pot experiment.
