“…The highest growth and yield parameter represented by root and shoot of Turnip and Chard was obtained with 40kg fed-1 applied calcium (Ca) and potassium (K) combined with 0.05 mM salicylic acid (SA) as compared with same levels of Ca and K without SA and control treatment. At 40 days of sowing, Chlorophyll a and Chlorophyll b and carotene of Turnip and Chard significantly increased by Ca and K combined with SA application [75].…”

Salt stress is one of the major abiotic stresses decreasing crop production, particularly in dry and semi–arid regions. Reclamation of salt–damaged soil is important as it is sweeping cultivable land day by day. Potassium is an essential element for plant development which is an extremely active ion in the soil system. Potassium is second to nitrogen in plant tissue levels ranging from 1 to 3% by weight. As a cation, potassium is highly mobile in plant and moderately mobile in the soil system. The essentiality of potassium is identified with its multiple roles in plants. Among these are the maintenance of cell turgor pressure and cell lengthening, osmoregulation, leaf and stomata movements, enzyme activation, phloem solute transport, cation/anion balancing, control of membrane polarization, cytoplasmic pH regulation, chloroplast structure and functioning, protein and starch synthesis, and energy preservation across membranes. As almost all of these processes are directly associated to plant adaptation to the in hospitable environment. It could be concluded that potassium uptake, transportation, and homeostasis play important role in conferring salt tolerance in plants.
